Low–fat high–protein fermented milk product with oat extract as a nature stabilizer

Nowadays, the use of plant components in terms of their pronounced functional properties is of high relevance. Oat extract contains gums, β–glucans, vitamins (A, B1, B5, B9, PP, H), minerals (Fe, I, K, Si, Mn, Cu, Mo, etc.) and essential amino acids. It has been proven that a long–term use of β–glucans showed the reduction of the risk of cardiovascular disease and diabetes and the regulation of cholesterol and blood sugar. β glucans also have immunoprotective, anti–inflammatory, antimicrobial, prebiotic effects and improve intestinal motility. The aim of study was to develop the technology of low–fat high–protein fermented milk product with functional characteristics. Oat extract was used as a natural stabilizer and a source of β–glucans. Maceration technique was used for the extraction. The recommended extraction parameters were established and physicochemical characteristics of the extract were studied. The recommended doses of oat extract when introduced into milk and the optimal heat treatment conditions of the milk–oat mixture were determined. The influence of temperature on the gel–forming properties of oat extract was investigated. The effect of oat extract on rheological behavior, water–holding ability and shelf life of the finished product was studied. Regular consumption of lactic acid microorganisms has a positive effect on the digestive system and metabolism. Based on the organoleptic characteristics and physicochemical changes during the fermentation process in comparison with the control sample (without oat extract), the recommended starter culture combinations (Lactobacillus acidophilus, Lactococcus lactis subsp, Lactobacillus bulgaricus) were proposed

Problem-based learning of college students as a condition of the development of environmental consciousness when passing to the sixth technological mode

The relevance of the research: the development of high-end manufacturing leads to an increase in the negative impact of man on the environment. So, today the issues of developing environmental consciousness in college students are relevant.The problem statement: the negative impact of a person on the environment is increasing. However, the development of the ecological consciousness of students, awareness of the consequences of environmental impact is not at the proper level that is necessary in the transition of society to the sixth technological mode.The purpose of the research is to prove that the formation of the cognitive activity of college students in the ecological aspect is a necessary condition for the development of the ecological consciousness of college students.To solve the problem, the article considers such research methods as the analysis of pedagogical literature, observation, synthesis, generalization, considers the issues of practical application of methods on the example of classes in physical and mathematical disciplines and classes in Ecology.The conclusions: The use of mechanisms for the formation of students’ ability to show initiative in problem-dialogical interaction in matters relating to environmental problems contributes to the development of students’ environmental consciousness, the growth of their responsibility for the effectiveness of their professional activities, and the impact on the ecosystem

Mammal fauna during the Late Pleistocene and Holocene in the far northeast of Europe

The paper summarises materials on the mammal remains in northeastern Europe, dated by radiocarbon. Altogether, 23 local faunas of small mammals and 47 local faunas of large mammals were analysed. Multidimensional statistical analysis shows a strong correlation between changes in small mammal fauna composition and climate changes throughout time. The correlations with the spatial gradients, however, are less pronounced. The faunas are classified into three groups: (1) faunas of Holocene age; (2) Late Pleistocene ‘stadial’ assemblages; and (3) Late Pleistocene ‘interstadial’ assemblages. In some cases, changes in species abundance are better understood in terms of biotic interrelations rather than of climatic effects. The most pronounced change in small mammal fauna composition and structure occurred at the Preboreal/Boreal boundary, and a less conspicuous alteration took place at the LGM/Lateglacial transition. The most noticeable transformation in the large mammal fauna composition is dated to the early Holocene. Less significant changes are observed at the Middle Weichselian/LGM transition and at the LGM/Lateglacial transition. It is safely concluded that variations in the faunas of small and large mammals recorded in NE Europe during the last 35 000 years occurred synchronously and unidirectionally.
