tert-Butylhydroquinone (TBHQ, tertiary butylhydroquinone) is an aromatic organic compound which is a type of phenol. It is a derivative of hydroquinone, substituted with tert-butyl group.
TBHQ is a highly effective antioxidant. In foods, it is used as a preservative for unsaturated vegetable oils and many edible animal fats. It does not cause discoloration even in the presence of iron, and does not change flavor or odor of the material to which it is added. It can be combined with other preservatives such as butylated hydroxyanisole (BHA). As a food additive, its E number is E319. It is added to a wide range of foods, with the highest limit (1 gram/kg) permitted for frozen fish and fish products. Its primary advantage is enhancing storage life.
It is used industrially as a stabilizer to inhibit autopolymerization of organic peroxides. It is also used as a corrosion inhibitor in biodiesel. In perfumery, it is used as a fixative to lower the evaporation rate and improve stability. It is also added to varnishes, lacquers, resins, and oil field additives.
...At higher doses, it has some negative health effects on lab animals, such as producing precursors to stomach tumors and damage to DNA. A number of studies have shown that prolonged exposure to high doses of TBHQ may be carcinogenic, especially for stomach tumors. Other studies, however, have shown opposite effects including inhibition against HCA-induced carcinogenesis (by depression of metabolic activation) for TBHQ and other phenolic antioxidants (TBHQ was one of several, and not the most potent). The EFSA considers TBHQ to be non-carcinogenic. A 1986 review of scientific literature concerning the toxicity of TBHQ determined that there is a wide margin of safety between the levels of intake by humans and the doses that produce adverse effects in animal studies.
Food Additive TBHQ May Protect from Avian Influenza Virus H7N9
“The recent H7N9 outbreak in China this past March had a mortality rate of more than 20 percent. That strain, which is new, is already showing resistance to the majority of existing drugs used to treat it. The need to develop new antiviral therapeutics now is crucial,” said senior author Dr Michael Caffrey from the University of Illinois.
...TBHQ is an effective antioxidant. It is used as a preservative for vegetable oils and edible animal fats. its E number is E319.
“The additive attaches to the Achilles’ heel of the virus – a loop-shaped portion of hemagglutinin necessary for binding to cells, making cell infection impossible. The loop on the hemagglutinin molecule represents a new therapeutic target, since existing drugs don’t go after it.”
“Any drugs that focus on the hemagglutinin loop would be totally novel to flu viruses, and so resistance, if developed, would still be a long way off.”
...They found that TBHQ was able to prevent the virus from infecting human lung cells in the lab.
The researchers are now looking for ways to enhance TBHQ’s ability to prevent infection.
