A kind of production method of probiotic active milk drink rich in organic selenium

Abstract

The invention belongs to the technical field of active milk beverage preparation, and particularly relates to a production method of a probiotic active milk beverage rich in organic selenium. Sodium selenite is added in different stages, so that the best combining condition between yeast and selenium is optimized; the selenium combining quantity is increased; the growth of the growth is facilitated; inorganic selenium is combined into organic selenium; the yeast is separated by a sheet frame press filtration or centrifugal method; selenium-enriched yeast powder is obtained by drying and deactivation, and serves as a raw material for secondary fermentation via probiotics such as bifidobacterium bifidum, lactobacillus bulgaricus, lactobacillus acidophilus, thermophilic streptobacillus and bacillus cereus, and secondary conversion via microbial enzyme; and inorganic selenium left in a yeast cell is converted into selenium protein and seleniferous protein basically completely. Therefore, the probiotic functional food beverage rich in organic selenium is obtained. The product can exert comprehensive health-care effects of the probiotics, the yeast and organic selenium.

Description

technical field [0001] The invention belongs to the technical field of active milk beverage preparation, in particular to a production method of probiotic active milk beverage rich in organic selenium. Background technique [0002] Selenium is an essential trace element for organisms, which cannot be synthesized in the human body. The total selenium content of the human body is 6-20mg. Selenium is distributed throughout various tissues, organs and body fluids, with the highest concentration in the kidney. The selenium in the male body is mostly concentrated in the testis and the vas deferens of the prostate, and will be excreted together with the semen. Since there are no long-term selenium storage organs in the human body, the selenium needed by the body should be continuously supplemented by sufficient selenium from the diet. The balance of selenium concentration has an important protective and promoting effect on the physiological functions of many organs and tissues. W...

Problems solved by technology

[0012] At present, there have been literature records of converting inorganic selenium into organic selenium, such as the patent document No. 2006100972884, which records a production method of probiotic yoghurt rich in selenium amino acids, which adopts the addition of selenous acid in the probiotic culture medium Sodium solution (inorganic selenium), which converts inorganic selenium into selenoamino acids through probiotic fermentation, has the problem that due to probiotics such as Bifidobacterium bifidum, Lactobacillus bulgaricus, Lactobacillus acidophilus, and Streptococcus thermophilus The ability to convert inorganic selenium is limited, so the conversion rate of inorganic selenium achieved in this patent is only 50%. Since there is still unconverted inorganic selenium in the finished product, and the proportion is very high, it has certain toxicity

And because the patent uses sodium selenite inorganic selenium as the raw material for probiotic fermentation, sodium selenite has a certain influence on the growth of probiotics
