What is tert-Butylhydroquinone CAS 1948-33-0?
Tert-butylhydroquinone (also known as tert-butyl catechol, abbreviated as TBHQ) is a type of phenol, formed by adding a tert-butyl group to the catechol molecule. Tert-butylhydroquinone (TBHQ), also known as tert-butyl catechol, is an efficient phenolic chemical compound used in the synthesis of antioxidants. It is widely applied in edible oils and foods rich in oils to prevent oil oxidation and deterioration, thereby extending the shelf life of the products and enhancing their safety.
White to light gray crystals or crystalline powders. It has a very slight special odor. It is suitable for crude oil and highly unsaturated oils, such as sunflower oil, etc. It is suitable for cooking oil and baked products to be used with BHA, but it is suitable for fried products. The general dosage is 100-200mg/kg. This product is white or slightly reddish-brown crystalline powder. Chemicalbook has a very faint special smell, which is almost insoluble in water (about 5‰), and soluble in organic solvents such as ethanol, ethyl acetate, and ether. The boiling point is 295℃, and the melting point is 126.5-128.5℃. It has a preservative effect on most oils, especially vegetable oils. It does not change color when encountering iron or copper, but it will turn pink if there is alkali present.
tert-Butylhydroquinone CAS 1948-33-0 Use
Antioxidants. Applicable to crude oils and highly unsaturated fats, such as sunflower oil, etc. For cooking oils and baked products, it is advisable to use in combination with BHA, but suitable for fried products. The general dosage is 100-200mg/kg.
Food oil additive testing.
It has the effect of preventing oxidation for most oils, plastics, rubber, etc. It does not change color when exposed to iron or copper, but it will turn pink if there is alkali present. Its antioxidant performance is excellent.
Antioxidants. tert-Butylhydroquinone is suitable for crude oils and highly unsaturated oils, such as sunflower oil, etc. For cooking oils and baked products, it is advisable to use it in combination with BHA, but it is applicable to fried products. The general dosage is 100-200mg/kg. Chemicalbook is used as a PVC anti-fish-eye agent and a food additive, and as an antioxidant, it can be used in edible oils, fried foods, biscuits, instant noodles, instant rice, dried fruit canned foods, dried fish products and pickled meat products. The maximum usage is 0.2g/kg.
It has excellent antioxidant properties, with stronger antioxidant capacity than BHT, BHA, PG (procyanidin B) and vitamin E; it can effectively inhibit the growth of Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Clostridium acetobutylicum and other bacteria, as well as Aspergillus niger, Aspergillus versicolor, Aspergillus flavus and other microorganisms. The antioxidant function of TBHQ is much superior to that of conventional antioxidants. Regarding vegetable oil, the order of antioxidant strength is: TBHQ > PG > BHT > BHA. Adding TBHQ to food can not only delay the oxidation and deterioration of oil-based products, but also has inhibitory effects on various microorganisms. It can be used as an antioxidant in edible oils, fried foods, dried fish products, biscuits, instant noodles, instant rice, canned dried fruits, and pickled meat products, and can also be used in cosmetics. ①TBHQ
TBHQ is a safe and efficient antioxidant for edible oils, suitable for vegetable oil, lard, etc. Especially because of its high melting point and boiling point, it is particularly suitable for fried foods. This product also has good antibacterial, antifungal, and antielemental yeast effects, which can enhance the preservation effect of high-oil-water foods. For example, adding it to peanut oil can significantly extend the shelf life, with its antioxidant effect being four times that of other varieties on Chemicalbook; adding it to sausage and dried fish products can prevent the products from going bad; adding it to fried foods and instant noodles can significantly extend the shelf life and prevent going bad. Industrial applications: 1. Antioxidant in rubber and plastic industries 2. Additive for PVC (anti-fish-eye agent) 3. Used as a pharmaceutical intermediate, organic synthesis 4. Stabilizer: Preventing resins and other substances from being oxidized due to oxygen
