Juice, jams, oils, and other products are made from the berries. However, valuable biologically active substances of its bark, leaves, and branches (tannins, flavonoids, allantoin) are practically not used. On the territory of the Kaliningrad region there are vast areas of wild-growing sea-buckthorn the bio-potential of which is not used, but is of practical interest. The aim of the study is to study the chemical composition of pulp, seeds, and shell of berries, as well as to assess the content of allantoin in the bark and branches of wild buckthorn and to develop recommendations for the integrated processing of all parts of this plant. In the experiments, four samples of sea buckthorn berries from the Baltic coast collected at the villages of Yantarny, Donskoye, Filino, and at Cape Taran, as well of sea buckthorn Lekora, which grows in Germany in the Brandenburg region, were investigated. of sea buckthorn was determined by high performance liquid chromatography. It has been shown that wild buckthorn can be used for complex processing to produce biologically active compositions for the food and cosmetic industries. A complex scheme is proposed for processing the main parts of sea buckthorn to produce wine, water-soluble powder additives, and concentrates from juice; from oilcake — sea buckthorn oil; from pulp — a vitamin-mineral complex and fiber; and from branches — allantoin and fuel briquettes.","PeriodicalId":148431,"journal":{"name":"Journal International Academy of Refrigeration","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122097786","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}

The food system was created by hydrothermolysis of meat and bone tissues of bream and their fine grinding, followed by enrichment with a vegetable component (carrots and beets) and food additives. The resulting mass was thinly rolled, molded, and dried hot at a temperature of 1800 C for 30 minutes. In semi-finished products and finished samples, organoleptic, physicochemical and microbiological parameters were determined during storage under specified conditions for 72 days. The scheme of microbiological studies to establish the shelf life of dried fish products was determined by the requirements of the MUC 4.2.1847–2004. The organoleptic characteristics of dried snacks were high, the snacks retained their original shape, the color during storage practically did not change on the 72nd day. Indicators of the chemical composition of ready-made snacks: the mass fraction of water is 18–20 %, table salt is 1.5 %, organic acids are 0.04–0.06 %. The LabMaster-Aw analyzer showed an indicator of the water activity of ready-made dried fish-growing snacks (0.5), the values of which indicate a high antiseptic resistance of the product. The results of microbiological studies to determine the expiration dates indicate that the product meets the regulated microbiological safety criteria. Taking into account the reserve factor of 1.2 for this product group, the shelf life is set for 60 days at a temperature of 4±2°C.","PeriodicalId":148431,"journal":{"name":"Journal International Academy of Refrigeration","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131959851","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}
