Quality and antioxidant traits of organic apricots (Prunus Armeniaca L.) at harvest and after storage

Abstract

In recent years, consumers are interested in low-input agricultural practices and healthy foods. The aim of this research was to assess the pomological quality and antioxidant properties of organic apricot fruits from several cultivars which have been previously evaluated under integrated cultivation. Apricot quality after cold storage (14 days at 4 ± 0.5°C, 90% relative humidity) was also tested in order to evaluate the fruit storability. Fruits from seven Italian apricot cultivars (Prunus armeniaca L.), grown under organic management system, were analyzed according to the main physicochemical traits, total antioxidant activity (TAC) and total phenols content (TP). Organic practices did not always have a significant influence on the major fruit quality attributes. Three out of seven genotypes positively responded to organic management showing, in particular, higher TAC and TP levels than integrated apricot fruits. Moreover, the capacity to keep unchanged the physicochemical and antioxidant properties of fruits after storage was an interesting result considering the high susceptibility of fresh apricots to conservation. The maintenance of high quality parameters could be an added-value for organic apricot productions. In conclusion, this study provides new perspectives for organically grown apricots, confirming the importance of the cultivar’s choice in order to obtain the best quality performances, in agreement to researches establishing as the genotype may influence more than any other parameters the fruit quality characteristics.
