Abstract: (63 Views)
One of the most important problems in the food industry is food oxidation. Pumpkin skin has been noted for having phenolic and carotenoid compounds with antioxidant properties. In this research, phenolic and carotenoid extracts of pumpkin peel were obtained using sub-critical water extraction and supercritical fluid extraction methods and then phenolic and carotenoid compounds were measured. The combined extracts had the highest antioxidant properties due to the synergistic properties of the extracts. In general, in all the antioxidant activity evaluation methods, the combined extract extracted using supercritical fluid and then the combined extract extracted using subcritical water showed the highest antioxidant activity. Also, the extraction method with subcritical water was more effective for extracting carotenoids and the extraction method with supercritical fluid was more effective for extracting phenolic compounds. There was a relationship between the amount of phenolic and carotenoid compounds of the extracts and the antioxidant activity. In all three methods antioxidant activities of extracts increased by increasing in extract concentration. The results showed that the combined phenolic-carotenoid extract of pumpkin skin can be a suitable alternative to synthetic antioxidants as a natural antioxidant.
