The objects of the study were: grapes of the ampelographic variety “Pinot Noir”; an extract obtained from dried \"sweet\" pomace of grapes remaining after the separation of the fermented juice; unfiltered unpasteurized unclarified kvass, obtained according to the classical technology on the concentrate of kvass wort with the addition of an extract from the pomace of grapes. The extract was obtained from grape pomace, pre-dried to a moisture content of 6% and ground to a particle size of 0.05 mm, by water extraction for 1.5 h at a temperature of 77–80 ° C at a hydromodule of 1: 14; the resulting liquid extract contains 2.0-2.2 g / 100 ml of polyphenolic substances. The extract was added to the composition of kvass \"before fermentation\" (at the stage of preparation of the main wort) and \"after fermentation\" (at the stage of blending the finished kvass). It was found that the introduction of the extract into the composition of kvass before the main fermentation promotes a better fermentation of dry substances, a higher content of polyphenols in the finished drink and a higher colloidal stability of these drinks. The samples with the addition of 10-15% extract were recognized as the best in terms of tasting qualities. According to the results of the study, the introduction of an extract from grape pomace into the composition of fermentation kvass is recommended at the stage of preparation of the main wort, in a dosage of 10% of the total mass of the main wort. 200-250 ml of kvass with such a dosage of grape pomace extract allows satisfying from 43% to 60% of the average daily requirement for polyphenolic substances.","PeriodicalId":374911,"journal":{"name":"Health, Food & Biotechnology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127247087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At this stage in the development of world breeding, not only the organoleptic characteristics of plants, but also their chemical composition, come to the fore. In connection with the growing interest in the effect of antioxidants on human health, breeders are increasingly turning their attention to the study of their comparative content in fruit, berry and vegetable raw materials. The results of a study of the influence of the grade of plant raw materials on the accumulation of substances exhibiting antioxidant activity (phenols, flavonoids, carotenoids) are presented. Popular vegetables and fruits cultivated and growing wild in the Samara region were selected as objects of research. The aim of the study is to obtain new information on the influence of such factors as the type and variety of fruit, berry and vegetable raw materials on substances with antioxidant activity (phenols, flavonoids, carotenoids). In the extracts of the analyzed samples, the total content of phenolic substances was determined by the method using the Folin-Ciocalteu reagent, flavonoids by the method based on the formation of a flavonoid-aluminum complex. The carotene content was determined according to GOST 8756.22-80 using acetone and hexane as extractants. The results of the study showed that the type and variety of plant raw materials are factors that directly affect the accumulation of the studied substances. To a greater extent, the results obtained relate to varieties of sweet peppers, fresh food pumpkin, rose hips. Significant variation in carotene content was recorded in pumpkin samples: from 1.20 to 4.90 mg%. Among the objects of research, it is recommended to use the fruits of the wild rose as a source of phenolic substances and carotenoids for the food and pharmaceutical industries. The work was carried out within the framework of the state assignment for fundamental research of the Federal State Budgetary Educational Institution of Higher Education «Samara State Technical University» No. 0778-2020-0005.","PeriodicalId":374911,"journal":{"name":"Health, Food & Biotechnology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125110755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
