Yeast Extract CAS 8013-01-2, Yeast Extract, CAS 8013-01-2
------
Yeast extract (CAS 8013-01-2), as a natural nutritional complex, has become a core raw material for food flavoring, microbial culture and functional health care due to its efficient freshness enhancement, nutritional fortification and biological activity. Its safety (GRAS certification) and process diversity (autolysis, flavor derivation) support cross-field applications.

1.Food Industry (Core Application)
Usage: Natural seasoning (substitute for MSG), nutritional supplement, dough conditioner.
Application scenarios and usage:
Food type, addition amount, efficacy
Condiments (soy sauce/sauce) 0.5-5% enhance umami flavor and moderate saltiness and sourness
Instant noodle/rice noodle seasoning 1-3% enhances the flavor intensity
For baked goods, 0.2% - 0.5% improves dough elasticity and delays aging
For meat products/canned goods, 0.1% - 0.3% mask off-flavors and enhance the aroma of the meat
Nutritional supplements are added as needed to supplement B vitamins and amino acids
2️. Biofermentation and medicine
Microbial culture: As a nitrogen/carbon source, it is used for culture media of Escherichia coli, lactic acid bacteria, etc.
Pharmaceutical raw materials
