The objective of this study was to evaluate the antioxidant activity of corn fiber oil (CFO). CFO was tested in two lipid systems, bulk oil and cooked ground meat, using peroxide value and 2-thiobarbituric acid tests, respectively. After characterizing the concentration dependence of CFO in cooked ground beef and turkey, subsequent studies were conducted in the meat systems to identify the relative contribution of CFO components (oryzanol, beta-sitosterol, or linoleic acid) to the antioxidant activity. CFO and oryzanol were also tested for synergy with propyl gallate.

520 $a The objective of this study was to evaluate the antioxidant activity of corn fiber oil (CFO). CFO was tested in two lipid systems, bulk oil and cooked ground meat, using peroxide value and 2-thiobarbituric acid tests, respectively. After characterizing the concentration dependence of CFO in cooked ground beef and turkey, subsequent studies were conducted in the meat systems to identify the relative contribution of CFO components (oryzanol, beta-sitosterol, or linoleic acid) to the antioxidant activity. CFO and oryzanol were also tested for synergy with propyl gallate.
520 $a Concentration-dependent decreases in lipid oxidation were observed with increasing CFO concentration, both in bulk oil and in the meat systems. The greatest inhibition of peroxide formation was observed at 5% CFO containing linoleic acid in bulk oil system. However, the degree of inhibition in bulk oil was not sufficient to be of practical value. In the meat system, the highest concentration tested, 0.75% CFO, showed the highest inhibition of lipid oxidation. The combination of three principal compounds matched the antioxidant activity of CFO. Synergy was observed in the combination of 0.25% CFO with 0.01% (w/w) propyl gallate. We conclude that CFO can play an important role not only as a modulator of cholesterol absorption in human health but also as a natural antioxidant in processed food products.
