“…As in our study, this reduction is associated with a higher proportion of oleic and linoleic acids, demonstrating the deleterious effect of these fatty acids on lipid synthesis. Costa et al (2018) reported a linear reduction of fatty acids from lipid synthesis in an experiment testing levels of inclusion of 0-24% of cottonseed in the diet, however, contrary to the current study, there was no increase in the proportion of oleic acid and linoleic.…”

Our hypothesis was that different sources of unsaturated fatty acids from oilseeds (sunflower, soybeans, and cottonseed) could alter milk yield, fatty acid profile, and the amount of unsaturated fatty acids yielded in milk. It aimed to evaluate the effects of lipid sources on yield and composition and fatty acids in milk of primiparous Girolando cows. Five cows in lactation (35 ± 8 days), with 410 ± 7.15 kg BW were randomly distributed in a 5 x 5 Latin square. Five experimental diets, namely a control diet without an additional source of lipid and four diets with different lipid sources: cottonseed, sunflower seed, whole soybean, or soybean oil, as lipid source, to reach 70 g/kg of ethereal extract dry matter basis were used. Cottonseed and soybean oil addition reduced daily yield by 15 and 22%. Oilseed can alter fatty acid profile in milk. Whole soybean provided greater daily milk and fatty acids yields.

“…Since 2018, a significant amount of research has been published on the analysis of the fatty component of dairy products using GC. These studies illustrate various aspects of studying the fatty component of dairy products, such as the influence of feed type on the fatty acid composition of milk (Costa et al, 2018;Kučević et al, 2019), the importance of polyunsaturated fatty acids for improving the nutritional value of milk (Nguyen et al, 2019;Khosravi et al, 2018), differences in the fatty acid composition depending on the feeding regime of animals (Agradi et al, 2020;Barać et al, 2018;Sacchi et al, 2020), the influence of fat content on the properties of dairy products (Wang et al, 2019;Paszczyk et al, 2020;Ogrodowczyk et al, 2021), etc. Unresolved issues.…”

Topicality. The use of selenium-protein dietary supplements (SPDS) is relevant from a medical and economic point of view, as it can provide consumers with the required amount of selenium, and increase the value and attractiveness of food products. The diet of a modern person is very diverse in the composition of fatty ingredients. Of all natural fats, dairy is the most complex and unique one in its chemical composition. SPDS “Syvoselen Plus” contains up to 10% fat in its composition, therefore, studies of its composition are of certain scientific interest in view of the above. In many scientific studies, gas chromatography is used to determine the composition of not only the fat fraction of additives containing vegetable oils and animal fats, but also organic acids. The study of the fat fraction and the fraction of organic acids of additives by this method allows determining and predicting the composition of similar fractions in the final product from SPDS. This, in turn, allows for comprehensive control of the quality and composition of such final products. The aim of the article is to determine the quantitative and qualitative composition of fatty and organic acids in the SPDS “Syvoselen Plus” by the gas chromatography method, and to compare the results of the determination with the indicators of a hypothetical ideal fat. When writing the article, statistical and physico-chemical research methods were used, namely, the gas chromatography method, with the help of which the following problems are solved: the composition of the fat fraction of SPDS is determined quantitatively and qualitatively; the degree of correspondence of the main indicators of the fat “Syvoselen Plus” to the hypothetical ideal is established; the composition of organic acids in the additive is determined. Results. The fatty acid composition of milk fat, milk whey and SPDS was studied. Dietary supplement “Syvoselen Plus” contains a significant amount of palmitic (3117.71 mg/kg), stearic (1618.61 mg/kg), oleic (1397.95 mg/kg) and meristic (1296.69) mg/kg) fatty acids, which is confirmed by chromatograms of fat fractions of milk fat and SPDS. The main indicators of hypothetically ideal, milk, whey fats and DDBS were presented. As a result, it was established that the composition of fat, which is most similar to the ideal one, among the objects of the study, has SPDS “Syvoselen Plus” (the indicator of the ratio of the sum of oleic and linoleic acids to the sum of pentadecanoic and stearic acids coincides with the indicator of ideal fat, and the indicators of the ratio of linoleic to linolenic acids and linoleic to oleic acids are close to the values of the indicators of ideal fat). The study of the composition of organic acids of SPDS was carried out. Fractions of succinic, azelaic, and levulinic organic acids are predominant, which may be due to the type of dairy products from which the serum was obtained, the storage conditions of dairy products and the serum itself, the type of microorganisms that carry out the fermentation process and can produce various organic acids, and the production process of dairy products and their composition. Conclusions and discussion. The analysis of the fatty acid composition and the quality content of organic acids in “Syvoselen Plus” dietary supplement confirmed the feasibility of using a dietary supplement in health food technologies, since the latter contains enough polyfunctional fatty and organic acids.
