Comparing:
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E509: Calcium Chloride (Firming Agent / Cheese Salt)
E306 is a natural mixture of alpha-, beta-, gamma-, and delta-tocopherols steam-distilled from vegetable oils (soybean, sunflower). INS 306, ADI is Not Limited, serving as the gold standard lipid-soluble antioxidant in fats and oils.
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.
