Quality Management
The problems of global warming influence on the quality of elite wines is considered in the article. The working out of an adaptive reaction to changing climatic conditions, based on agrotechnical activities and on the use of biotechnologies in the production of finished products are presented.
The comparative estimation of the chemical compound of the apple-tree fruits which have been grown up in the conditions of the central zone of Krasnodar territory, depending on weather conditions of the vegetation period is presented. The obtained data has allowed to develop interrelation models between accumulation RSV, sugars, ascorbic acid, the general pol-yphenols, natural antioxidants and weather conditions of the period of vegetation of an apple-tree
The results of research of commodity qualities and biochemical indicators of sweet cherry of different varieties are presented. The varietal features defining flavoring qualities of sweet cherry varieties of different periods of maturation are established. The best varieties with high commodity and biochemical indicators of fruits for industrial use are allocated
The results of research of 8 modern remontant raspberry varieties adapted to technologies for crop of berries in autumn period at the annual shoots are presented. The complex biochemical and technological evaluation of raspberries on commodity quality, content of soluble solids, sugars, organic and amino acids, vitamins and polyphenols is given. Varieties for targeted use in the manufacture of jam and frozen products are allocated
Fruit using in winemaking at sufficiently high concentrations contain biopolymers of different nature, that is difficult for clarification and filterability, provokes occurrence of colloidal haze of wines. The use of enzymatic catalysis considerably reduces the concentration of biopolymers. Enzyme preparations have a different activity, that is confirmed by the results of research of qualitative and quantitative composition of amino acids, and ultimately by composition and concentration of higher alcohols, aldehydes, acetals, simple and high-boiling esters
