Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E202: Potassium Sorbate (Soluble Antimicrobial)
E200 (Sorbic Acid / 2,4-hexadienoic acid) is an unsaturated organic carboxylic acid preservative with broad antifungal and antimold activity. INS 200, group ADI is 11 mg/kg bw/day (expressed as sorbic acid), active across acidic and neutral pH up to 6.5.
E202 (Potassium Sorbate) is the potassium salt of sorbic acid, offering 58% water solubility at room temperature. INS 202, group ADI is 11 mg/kg bw/day, widely utilized in beverages, syrups, and cosmetics to block yeast fermentation.
