Abstract
Today, consumers pay special attention to the quality of their products. They also expect a high level of innovation. Thus, the dairy sector's supply is increasingly focusing on the use of various additives with proven health benefits. The modern market of functional products consists of 65% dairy products. The basis of the technology of functional food products is the modification of traditional products, which ensure an increase in the content of useful ingredients in them to a level correlated with the physiological norms of consumption. Many scientific studies from different regions of the world are engaged in research, and their goal is to identify herbal supplements that have a beneficial effect on the human body. A specific feature of plant raw materials is the ability to synthesize a large number of various chemical compounds of various natures that have physiological activity. This article presents the results of studies on the effect of a biologically active additive obtained by using whey protein concentrate, saskatoon berries and mountain ash. The results of the physico-chemical, organoleptic parameters of yogurt obtained using the developed dietary supplement are presented. It was found that the content of proteins, vitamin C, and polyphenols in the finished yoghurts significantly increased. An increase in antioxidant properties was noted. The data obtained indicate the biological value of the developed yogurt was enriched with BIO-AP-IRGA dietary supplement.
