The article considers the issue of the influence of abnormal agrometeorological conditions on the yield capacity of early table grape varieties of interspecific origin in the Krasnodar region to create a mathematical model of minimum yield capacity. Paired correlation and multiple regression were used to assess the impact of abnormal agrometeorological conditions on the yield capacity. The yield capacity of grapes of early table varieties of interspecific origin was taken from different agroecological zones of the Krasnodar region for 1997-2020. Extreme agrometeorological indicators are calculated according to generally accepted methods. Using pair correlation, the most important extreme agrometeorological parameters were selected: the minimum air temperature of June-November of the previous year (r = 0.41), the total precipitation in May-July (r = 0.50) and the Selyaninov hydrothermal coefficient for May-July (r = 0.52). The prognostic model of the minimum yield capacity of early table grape varieties of interspecific origin included the minimum air temperature of June-November of the previous year and the Selyaninov hydrothermal coefficient for May-July. The model was tested according to the observed yield capacity indicators obtained in the Central Agroecological Zone on two varieties of early ripening of interspecific origin � Gurman Kraynova and Viktor. The predicted average minimum yield capacity of early table grape varieties of interspecific origin for agroecological zones and subzones of the Krasnodar region was determined using the developed yield capacity model. Agroecological subzones with high average minimum predicted yield capacity depending on abnormal weather conditions were identified � in the Black Sea zone, subzones BS1, BS2 and BS5 with yield capacity equal to or higher than 10 t/ha, in the Northern zone of subzones N1 and N3 with yield capacity above 9 t/ha, in the Western zone of subzone W1 with yield capacity above 9 t/ha, in the Central zone of the C1, C2 and C3 subzones with yield capacity above 8 t/ha. The lowest predicted productivity is shown by varieties in the subzones of the Central Agroecological Zone remote from the sea and in the Foothill zone. This technique for assessing the risks of cultivation is recommended to be used for any varieties of technical and table directions of use.

The paper presents the results of functional and structural modeling of products for personalized nutrition and substantiates the relevance of the development of specialized digital tools. The analysis of the production of food products in recent years has revealed the main trends in the structure of produced species. As objects for the organization of personalized nutrition, mass consumption products were chosen � bread and bakery products, confectionery, canned fruits and vegetables, soft drinks. As research methods, the methodology of functional and structural modeling of systems is used. Most food products contain various sets of ingredients, and those, in turn, consist of a certain set of chemical elements. Their combinations in various proportions lead to the fact that the final product will have certain properties, both positively and negatively affecting people's health. Accounting for these factors, identifying the composition of ingredients when designing products for personalized nutrition, in which the positive effect will be as favorable as possible, is a complex and time-consuming task that is impossible without the use of modern IT solutions. One of the basic stages of designing the corresponding digital tools is the description of the functional and structural model, which is presented in this article. This model allows to consider in detail the structure of future digital tools, the input and output information of each design stage, to determine the links and dependencies between the individual components of the system. The model is based on the SADT methodology in IDEF0 and IDEF3 notations. A TOP-diagram and three levels of decomposition are presented with an emphasis on the block of optimization of the component composition. Modeling of this particular process will later serve as the basis for creating digital tools for designing healthy food products with a given composition.

The article presents the stage of primary selection in the initial group of visually healthy grape bushes (about 500 pcs) of wine grape variety �Bastardo Magarachskiy� with high economically valuable characteristics, bred in the Institute Magarach. The studies were carried out in the production site of �Bastardo Magarachskiy� grape variety (No. 364, bush training AZOS-1, planting scheme 3 × 1.25 m) in �Alushta� branch of AO �PAO Massandra�. Agricultural recording for 500 bushes was carried out (average values for population were calculated, productivity indicators of �Bastardo Magarachskiy� variety with the degree of their variability were determined). In order to test the hypothesis about the regularity of distribution of quantitative characteristics in 500 initial bushes, we used three-sigma method and calculation of asymmetry and kurtosis indicators. It was established that distribution of such indicators as coefficient of fruitfulness k2 (665.2), percentage of developed shoots (652.08) and coefficient of fruitfulness k1 (8629) had the greatest positive asymmetry. The biggest negative asymmetry was noted in the distribution of such indicators as yield per bush (-502.6), number of fruiting shoots (-365.4), number of inflorescences (-337.8), number of eyes (-268.5), number of developed shoots (- 259.9), average bunch weight (-222.9), number of bunches (-218.2), productivity of a shoot in terms of raw bunch weight (-207.9). The greatest kurtosis was observed in the distribution of such indicators as coefficient of fruitfulness k2 (0.7), number of inflorescences (0.59), yield per bush (0.56), number of fruiting shoots (0.54), productivity of a shoot in terms of raw bunch weight (0.31). Variability degree of 9 characteristics (coefficient of fruitfulness k1, average bunch weight, number of bunches, number of developed shoots, number of eyes, shoot productivity in terms of raw bunch weight, yield per bush, number of fruiting shoots, number of inflorescences) is characterized as high (V= 26.54 - 41.79 %) according to the calculation of variation coefficient. The obtained data indicate the heterogeneity of population of the variety �Bastardo Magarachskiy� and the possibility of selecting highly productive protoclones.

In connection with the intensification of horticulture, as well as the relevance of the issue of import substitution, the issue of creating potentially high-yielding varieties of walnuts that can realize their biological productivity potential in the conditions of the North Caucasus is becoming increasingly important, since not only high yield capacity and valuable characteristics of fruits, but also, the increased adaptability to the specific environmental conditions of the region. At the same time, the signs of fruit quality still have one of the key values for the competitiveness of the variety. The article presents the results of research on the search for promising forms of walnut. In the course of expedition trips in order to select promising forms of walnut, valuable samples were identified, in which the lateral type of fruiting and a complex of economically valuable characteristics of the fruit were noted. In general, all 16 selected walnut forms are valuable for breeding programs for various characteristics (type of fruiting, yield capacity, large-fruitedness, important economically valuable fruit traits). Sample Nj-4 has a level of fruit setting on lateral shoots up to 80 %, which suggests the prospect of its use for breeding purposes for this trait. Forms Krd-2, Krd-3, Ps-13, Din-5, Din-10 can be considered promising in terms of the complex of phenotypic characteristics of fruits. These sampleshave a percentage of kernel yield, with the exception of Krd-3 (43.0 %), more than 50 %, good kernel extraction, kernel completion and can be used in breeding work as sources of economically valuable traits.

The article presents the results of three summer studies on the collection mother plot in the village of Uch-Dere. The characteristic of weather conditions by years for the research period is given. Thus, 2019 and 2021 were favorable years for the growth and development of the tea plant, compared to 2020. The total precipitation in 2019 was at the level of long-term data, and in 2021 this indicator was higher by 299 mm, which made it possible to compare the physiological response of tea plants to low levels of precipitation in 2020. The average monthly temperatures for 2019 and 2021 were within the normal range and are optimal for the tea bush in the humid subtropics of Russia. It has been established that 2020 has become a critical year in terms of the total precipitation during the tea leaf harvesting period and the temperature regime during this period. The conducted research made it possible to reveal the resistance of the studied varieties to abiotic factors of the growing environment; identify their susceptibility to drought and frost by the appearance of plants; determine points for each variety for drought resistance and winter hardiness; determine the degree of maturation of one-year growth during the growing season; establish the full number of tea leaf harvest per season, their seed productivity depending on the degree of pruning and weather conditions during the growth and development; select varieties that are donors for drought resistance and winter hardiness, in order to further involve them in the breeding process.

Grapevine bleeding is a sign of the grape plant coming out of a dormant state after winter. Despite this, more attention of scientists is focused on budbreak. According to the literature data, grapevine bleeding begins at air temperatures above 0 ºC. The date of the beginning of grapevine bleeding is also affected by soil temperature. The purpose of this work was a more insightful study of the dependence of the date of the beginning of grapevine bleeding on weather conditions: average, maximum and minimum air temperatures, average amplitude of air temperature, total precipitation and the sum of air temperatures above 0 and +5 ºC. The research was carried out according to the phenological data of the Anapa Ampelographic collection and the Anapa weather station for 2003-2020. The equations of multiple regression of the date of the grapevine bleeding of varieties of various ecological and geographical origin and separately of the Western European group are obtained. The coefficients of the paired correlation of the date of the beginning of grapevine bleeding with agrometeorological indicators are determined. The greatest influence is exerted by the average amplitude of air temperatures 10 days before the start of the grapevine bleeding phase � a significant pair correlation coefficient was obtained both for varieties as a whole and for groups, with the exception of intraspecific hybrids. The dependence is moderate inverse. Also, the average amplitude of air temperatures 5 days before the start of the grapevine bleeding phase has the inverse effect, but to a lesser extent. A direct weak and very weak connection of the date of the beginning of the grapevine bleeding is noted with average temperatures, the amount of precipitation for the period with temperatures above 0 º� and sums of air temperatures above 0 and +5 ºC.

The article presents the results of evaluating the efficiency of propagation of garden strawberry varieties under in vitro conditions. The paper compared the strawberry varieties of the Italian selection Asia, Cleri, Quicky and the varieties of the selection of the Federal State Budgetary Scientific Institution NCFSCHVW Nelli, Taira and Kemia. At the stage of introduction into in vitro culture, the Nelly varieties have a high level of regeneration � 80 %, Kemia and Asia � 73 %, Taira � 70 %, Clery � 62 %. The survival rate of explants Quicky variety was 34 %. A gradual increase in the concentration of 6-BAP during strawberry micropropagation increases the formation of strawberry shoots with each passage. An increase in the concentration of 6-BAP to 0.75 mg/l at the second passage contributes to an increase in the number of shoots by 1.5-2.7 times, depending on the genotype, and is 3.5-10.2 shoots. Increasing the concentration of 6-BAP to 1.0 mg/l at the third passage increases the number of shoots formed by another 8.9-31.4 % compared with the second passage and amounts to 5.1-11.3 shoots, depending on the variety. Thus, the varieties Taira, Nelli and Asia have a high breeding efficiency under aseptic conditions, on media with different hormonal composition, in total 22.7-26.0 microshoots per 3 passages, the average � varieties Clery and Kemiya � 13.7-14.8 shoots, low � variety Quicky � 10.7. The efficiency of rhizogenesis of regenerated plants of the studied strawberry varieties on a hormone-free Murashige-Skoog medium with half the content of macrosalts is 95-98 %. The successful rate of adaptation of microplants of the studied varieties ranges from 87 to 95 %.

Evaluation of grape resistance to low negative temperatures is relevant in connection with the increasing climate instability in the Anapo-Taman viticulture zone. An important metabolite associated with resistance to low temperatures is ascorbic acid. The purpose of this work is to conduct a comparative study of grape varieties of different ecological and geographical origin in terms of the dynamics of ascorbic acid content in the autumn-winter period and to identify varieties with increased resistance to low temperatures in terms of this indicator. The objects of research are grape varieties of various ecological and geographical origin: Kristall (control) � Euro-Amur-American origin; Krasnostop AZOS, Dostoynyi � Euro-American origin; Vostorg � Amur-American origin; Zarif � Eastern origin; Aligote � Western European origin. It was found that during t he autumn-winter period in the buds of grapes there was an accumulation of ascorbic acid. Its greatest increase was noted in the varieties Dostoynyi and Krasnostop AZOS � 3.6 and 3.9 times, respectively, in other studied varieties, this increase was 1.2-2.9 times. After artificial freezing, the least damage of cell membranes, determined by the accumulation of malondialdehyde (MDA), was noted in the Krasnostop AZOS variety � an increase in the content by 1.09 times. The varieties Kristall and Dostoynyi were next in terms of resistance � an increase in the level of MDA by 1.15 and 1.36 times, respectively. In other studied varieties, identified as unstable, this increase was 2.2-2.93 times. In varieties Krasnostop AZOS, Kristall, Dostoynyi after freezing, the content of AA increased � by 6.7-9.6%, i.e. ascorbic acid played the role of a low molecular weight antioxidant in suppressing the development of oxidative stress. According to the content and accumulation of ascorbic acid in the buds, the Krasnostop AZOS variety was identified out as the most resistant to extremely low temperatures. Next in terms of resistance were the varieties Dostoynyi, Kristall. The content of ascorbic acid in grape buds can be used as a diagnostic criterion in the selection of frost-resistant varieties for breeding purposes.

Micropropagation is a promising direction for obtaining a healthy, genetically homogeneous grape planting material. The efficiency of reproduction is determined by many factors, including the acclimatization of plants to natural environmental conditions. The difficulty of transferring in vitro plants to non-sterile conditions is associated with a number of physiological and anatomical features of in vitro plants, among which the low level of photosynthetic processes is of particular importance. The influence of various concentrations of sucrose in the culture medium and additives, simulating environmental stresses on the rates of photosynthesis of grapes during acclimatization, was studied. The content of sucrose 10g/l in the culture medium was the most optimal for the formation of the photosynthetic apparatus. Both low and high sucrose content in the culture medium negatively affected the formation of pigments and the efficiency of photosynthetic processes. The introduction of PEG and NaCl into the nutrient medium led to a decrease in the total content of pigments, the quantum yield of photochemical reactions, but increased the expression of RUBISCO activase. The use of ABA as part of the culture medium had a positive effect on the formation of pigments in grape plants during acclimatization. The effects of weak stresses on the photosynthetic parameters of grapes in in vitro culture and during the acclimatization period are identical to the effects of drought and salinity under natural conditions. At the same time, these types of influence have a positive effect on adaptive �anti-stress� reactions that prevent plant damage under ex vitro conditions, which ultimately increases the level of growth processes and the yield of seedlings during micropropagation of grapes.

This work presents the data on study results of two irrigation algorithms for Cabernet�Sauvignon grape variety in production conditions of the Livadia branch of FSUE PJSC Massandra in the South Coast of Crimea in 2019-2020. Experimental physiological algorithm provided for two water stresses to be carried out. The first short-term water stress was during the period of berry growth, t he second one � during the stage of berry ripening. The depth of water stress during the stage of berry growth in predawn values of water potentials in leaves was determined in the range of 0.5�0.55 MPa. The depth of water stress during the stage of berry ripening was in the range of �0.45��0.5 MPa. Crop load of plants in experimental version was determined as higher than normal � by 20 % compared to the optimal one. The control variant was a stress-free irrigation strategy against the background of optimal crop load. Basic tool to control water status of plants was a pressure chamber for measuring water potentials of leaves. Growing seasons of 2019-2020 were characterized by a significant rise of average monthly air temperatures compared to average long-term values and low annual precipitation amount: 357.0 and 410.6 mm, respectively. Such weather conditions have led to high evapotranspiration flow rate in grape plants. And yet, in the third decade of June, the plants of experimental variant experienced extreme water stress (�0.5��0.55 MPa). Ripening of grapes in stress variant of irrigation also took place with a moisture deficit. Average values of leave water potentials in predawn hours were �0.45-0.50 MPa. As a result of the research, it was found that stressful irrigation strategy against the background of an increased crop load, compared with a stress-free one and an optimal crop load, allowed an increase in the mass concentration of sugars by 1.5 g /cm3 , in the content of total phenolic substances by 28.3 % and coloring agents by 33.3 %.

The planting of basic mother grape plantations is usually carried out on sandy massifs, which have a number of specific properties, both positive and negative. One of these properties is the heterogeneity of the soil cover. First of all, this is due to the fact that sands are subject to deflation to a greater extent than fixed soils. The soil horizon can be partially or completely destroyed, carried by the wind and deposited on top of other soils. Thus, a new soil cover is formed, but with other factors of soil formation. In this regard, when transferring healthy seedlings to the open ground, plants often die. To avoid this, the laying of elite mother plantations on the lands of sandy massifs must be carried out taking into account the characteristics of these lands, including taking into account soil heterogeneity. The soil cover was typified on the Nizhnekundryuchensk basic mother grape plantations, as a result of which all the diversity of soil conditions was reduced to 5 types (microzones). The purpose of our study is to determine the influence of soil and ground conditions on the growth and development of grape plants, as well as to substantiate the feasibility of using fertilizers. Observations were carried out from 2004 to 2022 on 5 grape varieties from different ecological and geographical groups. As a result, it was found that the development of basic plants strongly depends on the type of soil conditions, while the dynamics of bush preservation indicators after several years of growth was noted. At the first and second types, plant development was the best, quantitative and qualitative parameters of the harvested vine parameters were optimal. The use of fertilizers on the third type of soil and ground conditions allows to obtain a vine in quality not inferior to the vine obtained from the first type of conditions.

Apple varieties have different response to fertilization and changes of root nutrition conditions. For three years, we studied the effect of fertigation on the content of nutrients in the leaves and the yield capacity in apple cultivars: Lobo and Spartan, grafted on rootstock 62-396. Planting scheme is 4 x 1 m, trees were cultivated on meadow-chernozem and dark gray forest soils. The experiment on meadow-chernozem soil was carried in AO "Dubovoe" (Tambov region), the experimental plot on dark gray forest soil was located in OAO "Agronom-Sad" (Lipetsk region). Leaf samples for analysis were taken during periods of the highest demand for the appropriate nutrients: phosphorus at the end of May, nitrogen at the end of June, and potassium in mid-August. Soil samples were taken before orchard planting and in August of the 3rd year of the study. The negative impact of drip irrigation on the content of soil nutrients was noted: the acidity increased on the meadow-chernozem soil, in both types of soil the content of available nitrogen decreased, as well as phosphorus and potassium in the upper layers of the soil. The content of the main nutrients in the leaves under fertigation depended on the variety response to fertilization, as well as on the soil type: the Lobo variety had a higher content of the studied nutrients in the leaves when fertigated on dark gray forest soil. The Spartan variety had a higher content of nutrients in leaves during fertigation on meadow-chernozem soil. Fertigation had a significant effect on increasing the yield capacity of Lobo variety on dark gray forest soil, and the yield capacity of Spartan variety on meadow-chernozem soil.

The ability to effectively protect orchards against apple scab is threatened by Venturia inaequalis developing resistance to fungicides with a particular mode of action. Three pathogen populations from orchards in the Krasnodar region were used in dose-effect tests to examine the susceptibility of the apple scab pathogen population to cyprodinil. One of the populations was collected in an abandoned garden and was the baseline. The rest of the populations are collected in commercial gardens with the annual use of fungicides, including cyprodinil. The effect of 7 concentrations of cyprodinil was determined: 0.001, 0.01; 0.10; 0.50; 1.00; 10.00 and 50.00 mg/l for the growth of monospore pathogen isolates on Leroux synthetic medium. A total of 63 fungus isolates were analyzed. The growth of mycelium on the fungicide was expressed as a percentage relative to the control variant of the medium. The concentration of fungicide active ingredient that resulted in a two-fold inhibition of growth, called the effective 50 % concentration (EC50), was found using a probit regression transformation of the relative mycelial growth on the active ingredient. Analysis of dose-effect curves showed hormetic responses at low fungicide concentrations. The results of the study revealed that the sensitivity of the original population was significantly higher than that of the two fungicidal populations at a significance level of p

Due to the high harmfulness of aphids in fruit and berry complexes and the poor knowledge of their life activity in the North-West region of Russia for three years 2019-2020 monitoring of their species composition and population dynamics was carried out in the educational and experimental orchard of St. Petersburg State Agrarian University (SPbSAU) (Pushkinsky district of St. Petersburg). Insect trapping was carried out with a Malaise trap. Nineteen species have been marked and identified, of which 6 are direct pests of fruit and berry crops. Five species damage field crops; the life cycle of six species is associated mainly with non-fruit trees and shrubs of the region; the remaining two species feed on weedage. The largest number of species was noted in 2019 � 17; in 2020 and 2021 � 6. At the same time, 2021 is the leader in terms of the number of identified individuals, moreover, mass capture was associated with the species Euceraphis punctipennis Zett. Species quite rare in the region, the Oxton aphid Hyperomyzus picridis Börn. and large thistle aphid Uroleucon sonchi L. were noted. Regularities in the dynamics of the number of insects during the growing season were analyzed. The largest number of aphids in the trap in 2019�2020 recorded in August-September, the period of their remigration to the primary hosts. In 2021, the maximum number of insects was observed at the end of May, due to migration to secondary hosts. The impact of weather anomalies in 2021 on the vital activity of phytophages was assessed. The largest number of aphids was observed in May due to high air temperature with sufficient precipitation. A further increase in temperature in June with absence or low total precipitation, significantly reduced the number of insect populations. The Malaise trap proved to be quite effective when used for monitoring aphids; its advantages lie in the fact that the trap can be installed at any point of any agrocenoses, is not stationary and is convenient for material selection.

Monitoring phytosanitary studies have shown differences in the prevalence and harmfulness of the European grapevine moth on vine plantations in the Rostov region in 2021 and 2022. Under favorable conditions for the development of the pest, yield losses from its impact on the generative organs of grapes can reach 40%, and the damage caused by it can contribute to the development of mycoses. A significant increase in the first generation of male butterflies was noted in 2022 compared to 2021. In our opinion, the increase in the number of the pest was due to favorable conditions for the wintering forms of the European grapevine moth. In the autumn-winter period, the sum of negative temperatures was 2.4 times less than the long-term average norm. In 2021, the second generation of the pest was the most numerous, in 2022 � the first, which can be explained by the influence of meteorological factors, especially air humidity. In particular, during all phases of the growing season in 2021, air humidity was above 60%. The most favorable year for the development of the third generation of the European grapevine moth was 2021, as evidenced by the largest number of pest males in pheromone traps. To reduce the harmfulness of the European grapevine moth, protective measures were taken against the second and third generations of the pest. For this purpose, the insectoacaricide Kinfos (active ingredient: dimethoate + beta cypermethrin 300 + 40 g/l) was used, the application rate was 0.4-0.5 l/ha. The use of the insecticide on the varieties Cabernet Sauvignon, Sibir'kovyy, Kristall, Tsvetochnyy contributed to a significant reduction in the prevalence of the pest, compared with untreated plantations. The listed varieties are characterized by the highest population of the pest. On the varieties Baklanovskiy, Denisovskiy, Kaberne severnyy, Kunlean', Pervenets Magaracha, Preobrazheniye revealed the least distribution of european grapevine moth.

Krasnodar region is the leading region of Russia in the production of grapes, one of the most important branches of production in the world. In the region, about 80% of the area is occupied by technical varieties. Fungal diseases, in particular leaf spots, cause significant damage to viticulture, as they can lead to a significant decrease in yield capacity. One of these diseases is necrotic leaf spot caused by fungi of the genus Alternaria Nees. The article provides an assessment of the incidence of hybrid forms of this disease. In the conditions of 2019, which was characterized by elevated average monthly temperatures during the growing season, the greatest spread of the disease was observed on hybrid forms of Tana 19 and Tana 92, on which the pathogen was present in a parasitic form. In the conditions of a later start of vegetation in 2020, the intensity of disease development was low on all varieties (0.7-12.3 %). In 2022, there was a shortage of precipitation in several months of the growing season, as a result of which the pathogen spread less on all hybrid forms and was present mainly as a saprotroph on weakened leaves. The spread and intensity of the disease development differed depending on the shoot tier � the most severe leaf damage is noted on older leaves of the lower tier, the least � on young, or leaves of the upper tier. Tana 92 was characterized by the greatest infestation of leaves of the middle and lower tier among all forms. When analyzing the mycopathocomplex of necrosis on the leaves of hybrid forms, it was found that it contains 8 species of hyphomycetes, of which 50 % are different species of Alternaria.

The research is devoted to the comparative analysis of physico-chemical and organoleptic parameters of ciders produced by Russian and foreign enterprises. Samples of products were taken from the trading network of Krasnodar by the method of spot sampling. The influence of beverage production technology on their physicochemical and organoleptic characteristics is shown. There was a significant difference between ciders made from freshly squeezed juice and concentrated apple juice, especially in the concentration of residual extract, which correlated with the fullness of taste of drinks. In ciders produced from freshly squeezed juice, a large concentration of residual extract, phenolic compounds, phosphorus, cations of potassium, calcium, magnesium, iron was noted. They were characterized by fullness of taste, bright aroma with tones of apples, pronounced tones of fermentation. At the same time, tones of alcohol and milk fermentation formed during fermentation of apple juice were identified in the taste. Cider samples made by fermenting concentrated apple juice had a simple fresh taste with hints of apples in taste and aroma. They showed the lowest concentration of residual extract, including phenolic compounds and ash alkaline and alkaline-earth elements. In some cider samples, the concentration of sodium cations had high values � up to 188 mg/dm3 , which indicates the use of water prepared using sodium-cationic filters. At the same time, a low concentration of calcium and magnesium cations was noted, which indicated their exchange for sodium ions during water treatment.

Protein deficiency is an acute problem in the modern world. On average, the recommended intake of protein per day for an adult is about 70 grams, and the indicators of actual protein intake are much lower and vary depending on the region. Currently, thanks to the development of innovations in genetics, new varieties of crops with a high protein content are being developed. These include amaranth and lentil crops growing on the territory of the Krasnodar region and the Russian Federation. The purpose of the study is to develop a sauce recipe based on amaranth greens and lentil seeds used as enriching protein additives. The objectives of the study include: creation of a conceptual model of protein-enriched sauce; selection of vegetable raw materials enriched with protein; development of a recipe for enriched sauce. During the research, the indicators of the chemical composition of raw materials were studied, confirming their technological significance for use as an enriching protein component for healthy food products; recipes for sauce with an increased protein content providing 16 % of the recommended daily intake were developed; regulatory documentation for a new type of product for healthy nutrition was developed; the efficiency of the investment project was calculated. Innovative criteria of the developed technology are the following indicators: the use of exclusively vegetable raw materials in the composition of products, without the addition of synthetic dyes and the possibility of changing functional properties by regulating the ratios of the components of the sauce formulation; increased preservation of nutrients in the finished product; physiological availability of sauce as an enriched product; high producibility of the method.
