This study was conducted to examine the antioxidant activity of 80% ethanol extract of celery seeds and to verify the effectiveness of extracts as a natural antioxidant to improve the stability of oil-in-water emulsions. The radical scavenging activity of 80% ethanol extract of celery seeds was significantly increased at 0.125, 0.25, and 0.5 mg/mL (p<0.05). Additionally, the total phenolic content and FRAP value were equal to 8.2±2.3 mol tannic acid equivalent/g extract and 195.0±12.6 mol ascorbic acid equivalent/g extract, respectively. The headspace oxygen content was significantly higher in the group treated with 80% ethanol extract of celery seeds than in the control group (p<0.05). The amounts of lipid hydroperoxide and conjugated diene were significantly reduced compared to the control group (p<0.05). The results showed that the extract of celery seeds had excellent antioxidant ability and it could be used as a natural antioxidant owing to the increased oxidative stability of the emulsified product.
