Abstract
The article presents the results of a study of the nutritional and biological value of grain drinks. The comparative analysis was made between fortified and non-fortified grain drinks, grain drinks were fortified with flaxseed flour to increase omega-3, resulting in a positive effect on the ω-6/ω-3 ratio. The aim of the study was to determine the change in the quality and composition of cereal drinks before and after enrichment with flaxseed flour. As a result of research, it was found that flaxseed flour increases the protein content in drinks. According to the content of fatty acid composition, grain drinks differ markedly from each other. On the basis of the conducted studies, it was proved that the enrichment of test samples with flaxseed flour had a positive effect on the content of Omega-3, as well as on the ratio ω-6/ω-3. The ratio of ω-6 to ω-3 in the developed products shows the following: rice drink, without enrichment - 0.67%, after enrichment was 3.23%, which indicates the correct ratio of ω-6 to ω-3; buckwheat drink, without enrichment - 0.81%, after enrichment - 3.76%, shows that enrichment has a positive effect on the ratio ω-6 / ω-3 and the content of ω-3 has become higher by 2.95%.The ratio of ω-6 to ω-3 in the developed products has reached optimal values, and the addition of a filler to grain drinks has increased the biological value of the product.
