Comparing:
E200: Sorbic Acid (Antifungal Preservative)
E300: L-Ascorbic Acid (Vitamin C Antioxidant & Flour Improver)
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.
L-Ascorbic Acid (E300, C6H8O6) is a water-soluble antioxidant, dough conditioner, and vitamin fortifier that scavenges dissolved oxygen, prevents fruit enzymatic browning, and cross-links wheat gluten disulfide bridges in commercial baking.
