Effect of cold storage on vitamin C, phenolics and antioxidant activity of five orange genotypes [Citrus sinensis (L.) Osbeck]
چکیده انگلیسی

The effect of cold storage on antioxidant profile and the antioxidant activity of five sweet orange genotypes [Citrus sinensis (L.) Osbeck], three blood (pigmented) varieties with different anthocyanin contents (‘Tarocco Messina’, ‘Tarocco Meli’ and ‘Moro’) and two blond varieties (‘Ovale’ and ‘Valencia late’), stored at 6 ± 1 °C for 65 d was investigated. During fruit storage, anthocyanins, hydroxycinnamic acids, vitamin C, flavanones and total phenolics were determined, and juice antioxidant capacity was measured by two different in vitro tests (DPPH scavenging activity and inhibition of induced linoleic acid peroxidation). The results showed an increase in anthocyanins, flavanones and hydroxycinnamic acids and a slight decrease in vitamin C in the blood oranges. Cold storage negatively affected flavanone concentration, while positively influenced vitamin C in blond orange varieties. Both antioxidant activity tests showed an increase in antioxidant capacity during storage caused mainly by phenolic accumulation (blood oranges) and vitamin C increase (blond oranges). Finally, correlations between antioxidant activity and total or individual phenolic components were examined.
