E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E471: Mono- & Diglycerides of Fatty Acids (Bread Softener)
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.
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
