Comparing:
E300: L-Ascorbic Acid (Vitamin C Antioxidant & Flour Improver)
E412: Guar Gum (Cold-Soluble Galactomannan)
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.
E412 (Guar Gum) is a natural galactomannan hydrocolloid extracted from guar beans (Cyamopsis tetragonoloba). INS 412, ADI is Not Limited (Quantum Satis), boasting 8x the thickening power of cornstarch and hydrating completely in cold water.
