Antioxidant Activity of Biphenolic Compounds Anchored on Mesoporous Alumina.
Phenolic antioxidants are used in the industry to delay the oxidation of fats, with the most used being butyl hydroxy anisole (BHA) and butyl hydroxy toluene (BHT). However, the consumer concern regarding their safety has motived the study of natural alternatives. In this sense, the aim of this work...

| description |
Phenolic antioxidants are used in the industry to delay the oxidation of fats, with the most used being butyl hydroxy anisole (BHA) and butyl hydroxy toluene (BHT). However, the consumer concern regarding their safety has motived the study of natural alternatives. In this sense, the aim of this work was to evaluate the behavior of 3,3′-dimethoxy-5,5′-di-2-propenyl-1,1′-biphenyl-2,2′-diol and 6,6′-dihidroxi-5,5′-dimethoxy-(1,1′-biphenyl)-3,3′-dicarbaldehyde free and supported on mesoporous alumina. Biphenolic compounds were synthetized by radical coupling and then
anchored on alumina by microwave assisted process. The antioxidant activity of these compounds was investigated by phosphomolybdenum method. The results showed that biphenolic compounds anchored on mesoporous alumina have a marked antioxidant activity, better than free antioxidants.
Biphenolic compounds supported on alumina display antioxidant properties allowing a new
opportunity for the developing in food and cosmetics packaging. |
