Comparing:
E282: Calcium Propionate (Bread Anti-Mold)
E306: Tocopherol-Rich Extract (Natural Vitamin E Antioxidant)
E282 (Calcium Propionate) is the calcium salt of propionic acid, the premier mold and 'rope' bacteria inhibitor in industrial yeast-leavened bakery goods. INS 282, ADI is Not Limited (Quantum Satis), preserving sliced bread for weeks without retarding yeast activity.
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.
