Phenolic antioxidants for carotene

  • Published:
Journal of the American Oil Chemists’ Society

Summary

Relative values for the carotene-stabilizing effects in mineral oil solutions of a number of phenolic-type antioxidants were determined. Certain relationships between molecular structure and antioxidant activity were observed. Alkylation of the phenolic compounds in general enhanced activity. Hydroquinone was shown to be an exception in the system studied.

Several antioxidants which have been accepted for use in lard have been found to be effective antioxidants for carotene in mineral oil solution. These include nordihydroguaiaretic acid, 2-t-butyl-4-methoxyphenol, alpha tocopherol, and esters of gallic acid. In addition, certain bisphenols used as anthelmintics were effective antioxidants for carotene.
