It is a white to light gray crystalline or crystalline powder with a very slight special odor. It is soluble in ethanol, acetic acid, ethyl ester, isopropanol, ether, and oils, and is almost insoluble in water (25 ℃,<1%; 95 ℃, 5%). TBHQ is an oil soluble antioxidant that can prevent or delay the oxidation and deterioration of fats in food.

The US Food and Drug Administration (FDA) allows TBHQ to be used alone or in combination (with BHA or BHT) for oil or fatty foods, including volatile essential oils, with a maximum allowable dosage of 200PPM. It can also be used in non-alcoholic beverages, margarine, and mixed nuts.TBHQ, also known as tert butyl hydroquinone, is a phenolic oil soluble antioxidant. TBHQ has high efficiency and stability, which can extend the shelf life of foods rich in oil and improve food safety.

Possible reaction pathways of 2,5-di-tert-butyl-hydroquinone (2,5-DTBHQ).Valgimigli et al. proposed a mechanism wherein semiquinone (2) reacts with molecular oxygen to produce 2,5-di-tert-butyl-1,4-benzoquinone (2,5-DTBBQ) and hydroperoxyl radical (HOO∙). The semiquinone (2) terminates a second propagation chain via either hydrogen abstraction (Reaction II) or addition reaction (Reaction IV) and these reaction pathways play a very critical role in the inhibition process.

TBHQ or PG is also added to the baked oil to improve its stability before and during baking.Based on the actual production needs of pastries and the industry's call, our company applies to expand the scope of use of the food additive tert butylhydroquinone (TBHQ), with an application to expand the scope of use to "07.02 pastries".Therefore, appropriate selection of antioxidants can inhibit the rancidity of oily food production and prolong the storage life of the product. Shelf life is considered an effective way to prevent the product from deteriorating due to oxidation.

This may be due to TBHQ being more prone to volatilization under high temperature conditions and losing its effectiveness, and under certain conditions, TBHQ may volatilize faster than BHT. Therefore, the application of microcapsule technology can solve this problem under high temperature conditions.
