Tertiary Butyl Hydroquinone is a synthetic food grade anti-oxidant, used to stabilize foods, fats and vegetable oils against oxidative deterioration and thus extending their storage life. Tocopherol, a natural antioxidant present in vegetable oils is often inadequate for oxidative stability. Even external addition of Tocopherol provides little or no increase in the stability and hence needs synthetic antioxidant. TBHQ inhibits an outstanding stabilizing effect in unsaturated fats particularly in Poly-unsaturated vegetable oils and inedible animal fats. TBHQ -can also be advantageous in essential oils, nuts, buffer fat and food packaging material. Thus, TBHQ provides a healthier and most favoured option for preserving food products.
