Evaluation of Tertiary Butylhydroquinone as an Antioxidant in Powdered Roasted Peanuts Products¹

Authors: M. W. Hoover , P. N. Painter

Abstract

A fifteen month shelf life study was conducted to determine the effectiveness of tertiary butylhydroquinone (TBHQ) as an antioxidant in products made from roasted peanuts (Arachis hypogaea L.). Five levels of TBHQ were studied, 0.0%, 0.01%, 0.02%, 0.03%, and 0.04% based on the fat content of the peanuts. Total carbonyl assays performed monthly served as indices of rancidity. Results indicate that the shelf life of the product may be extended up to thirteen months using the 0.02% level of TBHQ now allowed by the Food and Drug Administration. In addition, the quantitative determination of total carbonyls proved to be an acceptable indicator of rancidity of roasted peanuts.
