Description
We have established a change in the concentration of nitrous connections - amino, ammonium, total nitrogen and protein - during the fermentation of grape must by different races of yeast. Yeast which ensure reduction in the number of nitrous connections at the stage of the active fermentation were isolated

EVALUATION OF RED CURRANT VARIETIES ON THE FRUIT QUALITY
06.00.00 Agricultural sciences
DescriptionIn this article we present the results of the evaluation of 20 red currant varieties from NCRRIHV collection. Evaluation of varieties for commercial quality and biochemical composition of berries are presented

INFLUENCE OF THE NEW RACES OF YEASTS ON THE CHEMICAL COMPOSITION OF THE WHITE TABLE FAULTS
DescriptionThe influence is shown for the race of yeasts to the dynamics of the fermentation of grape must, the composition of organic acids and aromatic of components. The races, which ensure obtaining high-quality winemakings material are presented

DescriptionIn the article we show the investigations of aromatic wine produced from grapes of Sauvignon blanc grown in AF South in Temryuk District. As a result, the article estimates obtained good organoleptic characteristics of the taste, within 7.3-7.9 points, which is higher than the passing score. It was found that the greatest negative impact on the formation of mutual organoleptic properties have such flavors as metilatse-tal and the amount of volatile acids

06.00.00 Agricultural sciences
DescriptionIn the article we have studied biological and morphological features of perspective varieties of apple-trees of different ecological and geographical origins. Taking into account the requirements of intensive gardening we have defined biometrics, water regime, allowed to estimate the variety and determine its ecological plasticity. We have allocated apple-tree varieties of native selection such as Krasna Darya, Kuban scarlet, Peach, Renet Kuban and Pamyat Easulu; introduced varieties: Enterprise, Fuji, Red Chief, Golden Bee for sortment renewal and creation of intensive plantations of apple-trees in the Chechen Republic

SELECTION OF VARIETY-ROOTSTOCK COMBINATIONS OF PLUM FOR THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionThe article shows the results of integrated assessment of variety-rootstock combinations of plum on clonal rootstocks and different schemes of landing. We have defined the basic biometric parameters of trees, and specific indicators of productivity, allowing to identify the most optimal variety-stable rootstock combination for the conditions of the Krasnodar region

Description
The article investigates the possible pathways for the formation of crotonaldehyde in wine production in the result of the activity of wine yeast and lactic acid bacteria. It established that exposure to exhaust gases, noble rot, pathogens and pests on grape plant does not lead to the biosynthesis of crotonaldehyde in grape berry. The experimental data to identify probable pathways for the formation of crotonaldehyde during vinification has been presented. The effect of the test substance on the life of yeasts and lactic acid bacteria has been estimated

METHODS OF DETERMINATION OF CROTONALDEHYDE IN FOOD
DescriptionThe article presents a review of the existing methods for the determination of crotonaldehyde in food. The necessity of this component in the control of food products, including wine, is visible because of its toxicity and the probability of formation during microbial synthesis and chemical transformations. The article describes the developed qualitative method of determining the content of crotonaldehyde in table wines with spectrophotometry
