This study investigated the effect of natural and chemical food additives on the oxidative quality and shelf life of fried-balls used in Udong. Specifically, we evaluated the antioxidant activity of hot water extracts from broccoli added to fried-balls. When treated with antioxidants, fried-balls exhibited lower acid and peroxide values than that of the control group (untreated fried-balls). In addition, the analysis of GC/MS revealed that the contents of unsaturated fatty acids in the fried balls treated with antioxidants were higher than that of the untreated fried-balls, suggesting that the antioxidants slowed the oxidation. Our results showed that broccoli extract was effective in inhibiting oxidation of fried balls used in Udong. Therefore, these antioxidants might be used as food additives to preserve fried balls and consequently extend the shelf-life.
