Antioxidants are substances that prevent or delay food oxidation, improve food stability, and extend storage life.Food antioxidants can be divided into oil-soluble antioxidants and water-soluble antioxidants based on their solubility properties.Oil soluble antioxidants can be soluble in fats and oils, and have a good antioxidant effect on fats and fatty foods, preventing their oxidation, rancidity, and oil burning. Commonly used include butyl ether, dibutyl light toluene, gallic acid propionic acid vinegar, etc.TBHQ may volatilize faster than BHT.

Product ParametersTBHQ is white to light grey crystalline or crystalline powder, with very slight special smell, soluble in ethanol, acetic acid, ethyl alcohol, isopropyl alcohol, ethyl alcohol and oil, etc., a few are insoluble in water (25 ℃ <1%: 95 ℃ ﹤ 5%) TBHQ is a kind of oil-soluble antioxidant, which can prevent or prolong the oxidation of oil and fat deterioration in food.How to use the productSeed methodFirst dissolve TBHQ in a small amount of oil (or 95% alcohol solution), formulated as 5% ~ 10% of TBHQ oil (or alcohol solution), then directly or by the dosage added to the fat or

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.

Product ParametersTert butyl hydroquinone (TBHQ), also known as tert butyl hydroquinone, is a white crystalline powder with a temperature range of 126.5-128.5 ℃ and a temperature range of 300 ℃.

Product ApplicationsSuch as soybean oil, due to the presence of a large number of polyunsaturated fatty acids composed of glycerol vinegar (linoleic acid 52%, linolenic acid 8%), by the action of light, heat and air is easy to oxidative deterioration.

 It plays an irreplaceable role in the production process of pastry food and is also an important source of energy for consumers. However, the oxidation and rancidity of fats and oils, as well as the production of unpleasant flavors, are a problem that troubles many pastry food producers. They not only cause changes in the appearance, taste, and odor of pastry food, but also affect the length of its shelf life. Adding food antioxidants is the most convenient, feasible, and effective method.Pastry is generally made from grains, oil, sugar, and/or sweeteners, eggs, milk, etc.

1.Product ParametersMolecular formula: C10H14O2Molecular weight: 166.22CAS No.: 1948-33-0The oil in oily food undergoes oxidation in the air, producing free radicals and peroxides, which are early indicators of food rancidity. Peroxides further decompose to form small organic compounds such as aldehydes, ketones, and acids, which directly affect the taste and flavor of the product and cause great harm to human health.

Product ParametersSunflower oil antioxidant TBHQ, i.e. TBHQ, is a white or slightly reddish-brown crystalline powder with a very light special fragrance, almost insoluble in water (about 5 per cent), soluble in ethanol, ethyl acetate, ether and other organic solvents.How to use the productPumping methodSeed method of preparation of TBHQ concentrated solution, through the stainless steel quantitative pump in accordance with the prescribed ratio of injection needs to be stabilized with a fixed flow rate, flow rate of fat or oil in the pipeline.

TBHQ has good oil solubility and thermal stability, and does not change in color after heating.They are only suitable for high water content oil and fat foods such as biscuits, instant noodles, artificial milk oil, and mayonnaise. When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides.Oxidized fish oil is harmful to human health, so it is important to prevent oxidation and improve the stability of fish oil.

Fully dissolve and evenly disperse TBHQ in oil, otherwise it will affect the antioxidant effect.Some organic acids and their derivatives can enhance the activity of TBHQ. It is better to mix it with 0010.02% citric acid.Oil antioxidants are a type of substance that can prevent or delay the deterioration of oils or fatty foods, extend their shelf life, and tert butyl hydroquinone (TBHQ) is a high-quality edible oil antioxidant.It is the most effective antioxidant for most oils, especially vegetable oils.

When citric acid is combined with antioxidants, the higher the content of these impurities in the oil, the more obvious the synergistic effect.

There are two types of antioxidants, one is chemical synthesized and the other is natural antioxidants.       Chemical synthesis, such as BHT, BHQ, TBHQ, ethoxyquinoline, PE, etc., these are considered to be called chemical synthesis of antioxidants, these antioxidants have been banned in Europe, that in China and the United States, is the amount of additive per kilogram can not be greater than 0.2, these chemical synthesis of antioxidants, it is true that there is now some controversy, but the antioxidant effect is relatively good.

When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides. When citric acid is combined with antioxidants, the higher the content of these impurities in the oil, the more obvious the synergistic effect. TBHQ has good oil solubility and thermal stability, and does not change in color after heating. It can be added before and after the deodorization process of oil.
