Innovative technologies of extruded foods with alcoprotective action on the basis of fish raw

У статті наведений аналіз динаміки споживчих вподобань екструдованої снекової продукції на основі рибної сировини та обгрунтована доцільність створення харчових композицій з крупок зернових та картопляних пластівців, збагачених рибними порошками, з регулюємим хімічним складом та біологічною цінністю. З точки зору хімічних та біохімічних процесів описано властивості гліцину та бурштинової кислоти, як речовин, що нейтралізують токсичну дію ацетальдегіду в організмі людини під час вживання слабоалкогольних напоїв. Обгрунтована перспективність виробництва екструдованої продукції з компонентами, що перешкоджають руйнуванню клітин печінки та мозку у разі споживання слабоалкогольних напоїв. Проведена органолептична оцінка розроблених екструдованих продуктів, за результатами якої обгрунтована перспективність використання рибних порошків для виробництва екструдованих продуктів.The article analyzes the dynamics of consumer preferences of extruded snack foods on the basis of fish raw materials and substantiates the expediency of creating food compositions from grains of cereals and potato flakes enriched with fish powders, with regulated chemical composition and biological value. From the point of view of chemical and biochemical processes, the properties of glycine and amber acid are described as substances that neutralize the toxic effect of acetaldehyde in the human body during the use of low-alcohol beverages. The prospect of production of extruded products with components that prevent the destruction of liver and brain cells in the case of low-alcohol beverages is substantiated. The organoleptic evaluation of extruded products developed, the results of which proved the prospect of using fish powders for the production of extruded products. In the given work the technology of innovative food product - with functional alkoprotektornymi properties was presented. It is assumed that this product will expand the range of snack snacks to low-alcohol beverages and will be a reliable protection against the harmful effects of alcohol and its metabolism products in the human bod

Palaeogenomics of Upper Palaeolithic to Neolithic European hunter-gatherers

Modern humans have populated Europe for more than 45,000 years1,2. Our knowledge of the genetic relatedness and structure of ancient hunter-gatherers is however limited, owing to the scarceness and poor molecular preservation of human remains from that period3. Here we analyse 356 ancient hunter-gatherer genomes, including new genomic data for 116 individuals from 14 countries in western and central Eurasia, spanning between 35,000 and 5,000 years ago. We identify a genetic ancestry profile in individuals associated with Upper Palaeolithic Gravettian assemblages from western Europe that is distinct from contemporaneous groups related to this archaeological culture in central and southern Europe4, but resembles that of preceding individuals associated with the Aurignacian culture. This ancestry profile survived during the Last Glacial Maximum (25,000 to 19,000 years ago) in human populations from southwestern Europe associated with the Solutrean culture, and with the following Magdalenian culture that re-expanded northeastward after the Last Glacial Maximum. Conversely, we reveal a genetic turnover in southern Europe suggesting a local replacement of human groups around the time of the Last Glacial Maximum, accompanied by a north-to-south dispersal of populations associated with the Epigravettian culture. From at least 14,000 years ago, an ancestry related to this culture spread from the south across the rest of Europe, largely replacing the Magdalenian-associated gene pool. After a period of limited admixture that spanned the beginning of the Mesolithic, we find genetic interactions between western and eastern European hunter-gatherers, who were also characterized by marked differences in phenotypically relevant variants
