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.
