The effects of modified atmosphere packaging on quality of loquat fruits.

摘要

Loquat fruits cultivars 'Gold Nugget' and 'Sayda' were over-wrapped with 12.5 micro -, 14 micro -, or 16 micro -thick PVC films and kept at 0 degrees C for 60 days. Percent weight loss, skin color (L*, hue angle), firmness (N), total soluble solids (%TSS), titratable acidity (%TA), physiological and fungal disorders were determined immediately after harvest and at 15-day intervals. Over-wrapping with 12.5 micro -thick PVC film resulted in higher weight loss in both cultivars. Incidence of skin browning was higher in fruits over-wrapped with 16 micro -thick PVC films. Skin browning and decay and off-flavor limited storage life. Storage life of 'Gold Nugget' and 'Sayda' loquat fruits over-wrapped with PVC films could be stored for 30 days at 0 degrees C.
