Comparing:
E100: Curcumin (Turmeric Yellow Color)
E300: L-Ascorbic Acid (Vitamin C Antioxidant & Flour Improver)
E100 (Curcumin) is a natural diarylheptanoid yellow pigment extracted from the rhizomes of turmeric (Curcuma longa). INS 100(i), ADI is 3 mg/kg bw/day, providing bright yellow-orange coloration in mustard, cheese, and curry powders.
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.
