Tertiary butylhydroquinone (TBHQ) is one of the most effective synthetic chất chống oxy hóas for stabilizing unsaturated vegetable oils and animal fats against oxidative deterioration. Nó cung cấp superior carry-through protection during high-nhiệt độ chế biến such as frying, baking, and extrusion.
TBHQ is particularly effective in polyunsaturated oils where other chất chống oxy hóas may be less stable. It works by interrupting the free radical chain reaction of lipid oxidation, preventing the formation of off-flavors and odors. TBHQ can be used alone or in combination with other chất chống oxy hóas such as BHA, BHT, and citric acid for enhanced synergistic protection.
