Abstract
The invention belongs to the field of dairy products and foods and discloses black soybean selenium-rich yogurt and a preparation method thereof. The black soybean selenium-rich yogurt is prepared from the following components in parts by mass: 8 to 10 parts of black soybean, 10 to 12 parts of peanut, 6 to 8 parts of walnut, 40 to 50 parts of fresh milk, 5 to 8 parts of sucrose, 8 to 12 parts of skimmed milk powder, 1 to 2 parts of sodium caseinate and 3 to 5 parts of a selenium-rich fermentation agent. According to the black soybean selenium-rich yogurt provided by the invention, lactobacillus bulgaricus and streptococcus thermophilus are subjected to selenium-rich culture to obtain the selenium-rich fermentation agent; the selenium-rich fermentation agent is applied to yogurt which is prepared by taking foods containing rich nutrient substances, such as the black soybeans, the peanuts and the walnuts, as main raw materials, and the yogurt is fermented and after-ripened to obtain theorganic selenium-rich yogurt; the black soybean selenium-rich yogurt contains rich nutrient substances, and the content of selenium in the yogurt is also improved; the black soybean selenium-rich yogurt has a dual health-care effect.
Description
technical field [0001] The invention relates to the technical field of dairy products, in particular to black soybean selenium-enriched yoghurt and a preparation method thereof. Background technique [0002] Selenium is an essential trace element for the human body. It plays an important role in regulating the normal metabolism of the human body. It has many functions such as improving the body's immunity, scavenging free radicals, delaying aging, preventing tumors and cardiovascular diseases. The human body needs to take in enough selenium every day, but the content of selenium in natural foods is generally low. The conversion of inorganic selenium into organic selenium through artificial enrichment can not only improve the physiological activity and absorption rate of selenium, but also reduce the toxic and side effects of inorganic selenium . [0003] Yogurt is a kind of dairy product made of fresh milk, adding a certain proportion of sucrose, after high-temperature ster...
