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.

How to use TBHQ (Tertiary Butyl Hydroquinone)
Â
Food preservativeTBHQ is used as a preservative for unsaturated vegetable oils and many edible animal fats.Usage rate: 0.01-0.1%.
It does not cause discoloration even in the presence of iron, and does not change flavor or odor of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole (BHA).It is added to a wide range of foods. Its primary advantage is extending storage life.Â

OtherIn perfumery, it is used as a fixative to lower the evaporation rate and improve stability.
It is used industrially as a stabilizer to inhibit autopolymerization of organic peroxides.
It is used as an antioxidant in biodiesel.
It is also added to varnishes, lacquers, resins, and oil-field additives.
