2021
The article presents data on the development of a new fermented milk product kefir from unconventional milk raw materials of goat’s milk and with the addition of blackberry vegetable additive. It is scientifically justified to use blackberry puree in the production technology, as well as the use of an unconventional type of milk for the manufacture of kefir. The influence of blackberries on the quality indicators of the developed kefir was also investigated. Comparative analysis of kefir with different concentrations of blackberries was carried out. According to the results of organoleptic evaluation, it was revealed that the consistency in all samples is uniform, without disturbing the clot. The taste is sour milk, slightly sharp, without extraneous flavors and odors. There is a good slightly sweet blackberry taste and smell with an increase in the concentration of the additive. It can also be noted from the results that kefir with blackberries is enriched with iron and other micro and macro elements in the comparison with the control sample. According to physicochemical indicators, the sample with 10% replacement of milk with mashed potatoes was identified as the closest to the control. The benefit of goat’s milk kefir is due to the presence of various substances necessary for life. The properties of raw materials used are preserved and even enhanced considering the use of fermentation. Such kefir has a lot of natural proteins, the product is easily digested and absorbed by the body. Goat’s kefir makes it possible to improve digestion and metabolic processes in regular consumption. This product reduces the risk of developing most intestinal infections because of rich composition. There are probiotics in such kefir that oppose the spread of harmful microflora in the intestine. The product includes potassium and magnesium minerals that are especially important for normal operation of heart and vessels. There is phosphorus and calcium in it. The joint action of these minerals activates the process of regeneration and strengthening of bone tissue.
