  • ANTIOXIDANT IN FEED & FOOD; ANTIDEGRADATION AGENT FOR RUBBER
  • Antioxidant, used as post-harvest fruit-drop to prevent common scald of apples & pears in storge; Formerly added to poultry feeds & forage crops
  • Insecticide; antioxidant; flex-cracking inhibitor; post-harvest preservation of apples (scald inhibitor)
  • TO PRESERVE COLOR OF PAPRIKA, CHILI POWDER & GROUND CHILI
  • Used as a fruit dip for prevention of common (superficial) scald in apples
  • Antioxidant for rubbers
  • Antioxidant for food
  • Used to retard the oxidation of vitamins A and E, carotene, xanthophyll pigments, and to stabilize rendered animal fats and vegetable oils in animal feeds
  • MEDICATION **QC REVIEWED**
