Walnut oil antioxidant TBHQ
It is soluble in ethanol, acetic acid, ethyl ester, isopropanol, ether, and oils, and is almost insoluble in water.Tertiary butylhydroquinone, abbreviated as TBHQ, was approved as a food additive by the US FDA in 1972 and later by other countries around the world.The tert butanol method is widely used and can be catalyzed by strong acids such as concentrated sulfuric acid and concentrated phosphoric acid. Both domestic and foreign patent literature have reported this process, such as using toluene or xylene as solvents, the selectivity and yield of this reaction are relatively ideal.
Product Parameters
Molecular formula: C10H14O2
Molecular weight: 166.22
CAS No.: 1948-33-0
Product Characteristics
1. Tertiary butylhydroquinone is a highly efficient, low-toxicity antioxidant phenolic antioxidant with excellent antioxidant effect, and with the existing food antioxidants BHA, BHT, PG, etc. Comparison of antioxidant capacity as high as 5-7 times
2. synergistic: with other antioxidants (such as BHA, B HT) and chelating agents (such as citric acid, etc.) together, there is a synergistic effect.
3. High temperature resistance: it can be applied to high temperature processed food, such as frying food, with good thermal stability.
4. Antimicrobial effect: can effectively inhibit the growth of bacteria and mold.
5. Non-coloring: no change in flavor and color when used because of encountering iron or copper ions.
6. Safety: Its acute toxicity layer is low toxicity level.
7. grease solubility: soluble in animal and vegetable fats and oils, easy to add and use.
Caveat
TBHQ should be fully soluble and evenly dispersed in fats and oils, otherwise the antioxidant effect will be impaired.
Some organic acids and their coolants can enhance the activity of TBHQ. It is better to mix with 0010.02% citric acid.
This product should not be mixed with PG (propyl gallate). Avoid using this product under strong alkaline conditions.
