Freshly harvested loquat (Eriobotrya japonica Lindl. cv. Dahongpao) fruit were exposed to 100% N2 for 6 h at 20°C and then stored at 5°C for 35 days to investigate the effect of short-term N2 treatment on quality of the fruit. Fruit decay rate, total soluble solids (TSS) and total titratable acidity (TA) contents, membrane permeability, malondialdehyde (MDA) conten were measured. The short-term N2 treatment significantly delayed the increase of fruit decay rate and delayed the decreases of total soluble solids (TSS) and total titratable acidity (TA) contents, thereby maintaining better eating quality and extending the storage life of the fruit. The short-term N2 treatment also markedly delayed the increases in membrane permeability, malondialdehyde (MDA) content. These results suggest that a pre-storage pure N2 treatment for 6 h can effectively reduce fruit decay, delay the peroxidation of membrane lipid and maintain quality of loquat fruit. Therefore, a short-term N2 treatment in combination with low temperature could be a useful technique to maintain quality of postharvest loquat fruit.
