Quality Management
The results of determination of frozen strawberry quality grown under various soil management systems are presented. It was found out that soil mulching had a negative effect on the content of dry soluble substances, sugars and organic acids of berries. Juice-retention ability of the berries. correlates with the amount of dry soluble substances in them before freezing, and in turn with the soil management. Frozen Honey strawberries grown without mulching had a high juice-retention ability.
According to the technological requirements for table grapes the transportability of variety is an important quality criterion. It is not always possible to characterize the transportability of table grapes varieties by the transportability coefficient, so the task of our research was to develop a method for objective evaluation of transportability of table grapes varieties and to determine the percentage of influence of cultural practices on transportabilitys indexes. Based on a study of indirect transportabilitys indexes of table grapes varieties and the results of conducted discriminant analysis, the regression equations describing evaluation of a concrete grapes variety for three levels of transportability were proposed. These equations allow to evaluate the impact of different cultural practices on the percentage of transportabilitys properties of a variety in its relation to different groups of transportability. With the purpose of testing the proposed method, the evaluation of impact of foliar feeding (as a cultural practice) on transportability of table grapes varieties was given. The analysis of data showed that, in most cases, the foliar feeding had a significant impact on indirect transportability indexes of studied varieties. The obtained regression equations were also tested with the purpose to evaluate the transportability of new table grapes varieties.
The purpose of this work is to establish the dependence of foamy properties of wine materials, made from varieties of interspecific breeding Bianka, Pervenets Magaracha and Podarok Magaracha, from a place of grapes growth and technology of its processing. For research of wine materials produced by the enterprises of Anapa and Temryuk area of Krasnodar Region are chosen. The results of research showed that the value of foam-forming ability of wine material depends on varietal features of grapes not only, but also on a place of its growing. It is established for all studied grapes varieties the following regularity: in the samples developed from grapes, growing in the Temryuk area, the value of foam-forming ability is slightly higher, than it is in wine materials from the Anapas area. The increase in height of foam column during samples foaming to 11-13 mm was observed in a course of research of wine materials of Aligote and Podarok of Magaracha. The conclusion is drawn that in Aligote and Podarok Magaracha wine materials the surface-active substances with raised foam-forming (not defaming) function is prevailed. The wine materials produced from interspecific hybrids of grapes of Bianka, Podarok Magaracha, Pervenets Magaracha and Aligotes classical variety, have close value of foam-forming ability and a surface tension. The results of conducted research show, that the technology of production of wine materials had the greatest impact on foam-forming ability.
The article is devoted to the development of QMS process guidance "Corrective and preventive actions" for the LLC SIE "Mikrovinodelie", which is one from important governing processes of the quality management system. The actuality of the development connects with the need of accelerate development of small-sized high-tech enterprises for processing of agricultural production on the basis of creating for them of a favorable competitive environment. The process of prevention and correction of actions for the release of products conforming to the requirements of national and international standards is the basis of eliminating and preventing of actual or potential inconsistencies in products, processes and documentation and provides the confidence of enterprise in its efficiency and competitiveness. The methodological basis of the research is the principle of process approach to development of quality management system. The process algorithm of "The corrective and preventive actions" is developed and it is based on the prevention of inconsistencies in the quality of wine production and removing of their causes. The order of fulfillment of operations is described, the input and output requirements to the process with links to regulatory documents governing there execution are advanced, the criterions for assessment of quality of the execution of this process and the matrix of distribution of responsibility are elaborated.
The purpose of the work is to establish the influence of packing materials on the chemical composition, organoleptic indices and stability of alcohol beverages. The glass bottles, intended for bottling of alcohol beverages, vodka and the wines, that were being stored in the glass bottles, the wines, that were being stored in the "packet in the box" and in the container from the combined materials were the subjects of study. The estimation of the bottle's quality were carried out by use of methods of GOST 2131-2013. The concentration of volatile impurities in the beverages was determined by the method of gas-liquid chromatography (rystal 2000M) and chromatomass-spectrometry (mass spectrometer of larus 600T, the USA). The experimental data about the influence of the packing quality on change in color, taste and aroma of alcohol beverages in the process of their storage are adduced. It is shown that the leaching of glass leads to the disturbance of the exterior view of production, its taste and aroma, and formation of dimness. The application of the combined packing metallized materials does not influence on safety of beverages, but it contributes to reduction of their quality and to formation of untypical aromatic compounds. In the aroma and taste of experimental wines the hydrogen sulfide tone, the bitterness and also the unpleasant tones of animal musk are identified. The substances whose presence in the wine lead to the formation of the strongly expressed outside tones are discovered (2-Meth.tetrahyd.thiophen-3-one, 3-(Methylthio)-propyl acetate, 3-(Methylthio)-1-propanol, 4-Oxopentanethioic acid). The substances of 2-Methoxyfuran, 2-Amylfuran, Furfuryl of methyl of ether, 2-Acetylfuran, 2-Acetyl-5-methylfuran, 2-Furanmethanol, 3,4-Dimethylfuran-2,5-dione, 3-Methyl-2,5-furandione, 5 (Ethoxymethyl) - 2-furaldehyde, 2,5-Furandicarbaldehyde, 5-Hydroxymethylfurfural, which are formed as a result of hot bottling and wine contact with container are revealed. The components (Tetramethylthiourea) of the packing material, which passed into wine from the market container in the process of storage are identified for the first time.
