Tert - Butyl Hydroquinone (TBHQ)
TBHQ (Tert Butyl Hydroquinone) is a synthetic food grade antioxidant used for stabilising various oils, fats and foods against oxidative deterioration, thus retarding development of rancidity in these products and considerably increasing their shelf and storage life. TBHQ has an exceptional stabilising effect in unsaturated fats, particularly in polyunsaturated vegetable oils and in edible animal fats. TBHQ can also be widely used in essential oils, nuts, inedible animal fats, butterfat, packaged fried foods and food packaging materials such as Glassine and Paraffin wax.

Applications:
TBHQ is an established and excellent antioxidant for vegetable oils and fats. The use of TBHQ (about 0.02 wt%) stabilizes oils like Palm Oil, Soyabean Oil, Sunflower Oil, Peanut Oil, Coconut Oil, Mustard Oil, Rice Bran Oil, Corn Oil etc. TBHQ will ensure good storage properties for both the oil and the cooked product. TBHQ is also found to be very effective in protecting partially refined oils and crude oils during storage prior to refining.
TBHQ can also be easily incorporated in Fats, Animal fats, Lemon oil, Lards, Butter fat, Orange oil etc. for stability. TBHQ in combination with BHA, BHT and Propyl Gallate can be used effectively for various other antioxidant applications.
