Comparing:
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E500: Sodium Bicarbonate (Baking Soda / Ins 500ii)
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.
E500 (Sodium Carbonates / Sodium Bicarbonate NaHCO3) is a mineral salt leavening agent and pH buffer. INS 500(ii), ADI is Not Limited (Quantum Satis), decomposing under heat and acid to produce carbon dioxide bubbles that expand cakes, cookies, and pretzel crusts.
