Application methods
Direct Method

A fat or oil can be stabilized by heating to a minimum of 60~70℃ and agitating sufficiently for 10~15 minutes to dissolve the antioxidant. The agitation (not so vigorous that excessive air is entrapped) should be continued for an additional 20 minutes to ensure uniform distribution.

Concentrate method

Concentrated solutions of antioxidant can be prepared by dissolving TBHQ in a small quantity of fat or oil (or 95% ethanol) to make a 5~10% TBHQ solution. Directly introduce this pre-made solution into the oil and fat. Agitation is necessary for uniform distribution.

Pump-mixing method

The concentrated TBHQ solution made from concentrate method is fed into the inlet to the circulating pump. A stainless-steel proportioning pump is used to meter the TBHQ concentration into the oil at a desired rate. Turbulence should be sufficient to thoroughly mix TBHQ in the oil before the mixture reaches the storage tank.

Spray method

Food products such as nuts, preserved meet products, fish products can be sprayed directly with a dilute TBHQ solution. The concentration of TBHQ solution should be adjusted as required depending on the type of food product. Generally, 0.02% TBHQ ethanol solution is suggested and make sure antioxidant is spread uniformly.

Mixing method

Blend and mix directly with solid ingredients.


 TBHQ must be fully dissolved in oil to achieve optimum antioxidant effectiveness

 TLimitation of TBHQ addition is less than 0.02% or 200ppm (% by weight of food)

 Citric acid could enhance the antioxidant activity of TBHQ

 TTBHQ must not be mix-used with Propyl Gallate (PG)

 Avoid using this product under alkaline conditions
