The article presents material on the production of a new class of bio-correctors in the form of cryopowders from fruit raw materials grown in the Adler district of the Krasnodar Territory. Fruits of shadberry, feijoa and persimmon are chosen as research objects. Fruits have high characteristics of quality, but low shelf-life. The chemical composition of fruits contains a significant amount of easily digested carbohydrates, vitamins, macro and micronutrients. The dependence of the moisture content of fruit raw materials on the duration and speed of low-temperature drying is investigated. Mathematical substantiation of the freezing process and the contribution of dry substance heat capacity, ice and water to the heat generated during the water crystallization are given. The technological apparatus scheme for the production of cryopowders from fruit raw materials has been improved. It is based on raw material dehydration in a gaseous nitrogen environment, shock low-temperature freezing of research objects and ultrafine grinding of pre-prepared and dried raw materials in a liquid nitrogen environment.
A technology, based on the production of wine beverages from grape cryopowders in the mountain-valley zone of the Republic of Dagestan, is proposed. The data on the vacuum microwave drying of grape raw materials and subsequent grinding in a cryomill are presented. The modes of grape raw material preparation and its subsequent dehydration and cryo-grinding, which provide the possibility of successful use in the dried state in the production technology of wine drinks, are proposed. The principal feature is the use of whole grapes as a raw material, with rinds and seeds. The physical and chemical indicators, the content of phenolic substances and the organoleptic indicators of wine beverages made according to the traditional technology and the beverage made from grape cryopowders were studied. A comparative assessment of beverages was made. It is established that vacuum microwave drying conduces to better preservation of the properties of raw materials and finished products. The organoleptic assessment showed that the wine drinks developed according to the proposed technology had a more intense color and a more pronounced flavor of sweetness and sourness than traditional wine beverages. The advantage of this technology is the ability to transport grape cryopowders in unregulated temperature conditions to any point close to the consumer and carry out the production of wine beverages there.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
