E412: Guar Gum (Cold-Soluble Galactomannan) vs. E509: Calcium Chloride (Firming Agent / Cheese Salt)
Comparing 2 standards across 10 specifications. 9 key differences identified.
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.
E509 (Calcium Chloride / CaCl2) is an inorganic calcium mineral salt. INS 509, ADI is Not Limited (Quantum Satis), serving as a crucial firming agent in canned tomatoes, tofu coagulant, and rennet coagulation restorer in pasteurized milk cheese making.
