Due to the growing human need to supply food and micronutrients to the body, the use of supplements can meet basic human needs to a large extent. Hydrolyzed yeast (yeast extract) is prepared as a nutrient source from Saccharomyces yeast as the main ingredient. It is rich in vitamins, proteins and essential substances for growth and development. Yeast extract is known as a useful and natural food supplement and its various products are used by humans. Yeast has been used by humans as a factory for producing proteins and nutrients for many years, and with enzymatic processes, this cell can be used as a useful and nutritious substance for the growth of various cells from bacteria to animal cells. Compounds of this substance include essential amino acids, which are normally produced by this yeast. The main active compounds in yeast extract contain all B vitamins except vitamin B12, except brewer’s yeast with vitamin B12. ) Is also enriched.
