摘要: 采后大红袍枇杷果实用0.01~0.03mm厚聚乙烯薄膜袋密封包装结合1℃低温贮藏,可显著抑制果实失水,延缓果实可溶性固形物(TSS)、可滴定酸(TA)和VC下降,保持果实新鲜外观和品质,而对果实腐烂无显著影响,果实贮藏期可达20d以上。薄膜密封包装在20℃高温下贮藏,虽可有效抑制果实失水,但促进果实腐烂发生,这与包装袋内CO2和C2H4积累,从而促进果实的衰老和导致果实的生理失调有关。

Abstract: Loquat fruits (Eriobotrya japonica Lindl.cv.Dahongpao) were seal-packaged with different thickness of polyethylene film (0.01 -0.02 and 0.03mm,with no film packaging as control ) and stored at 1℃ and 20℃.At both temperatures .film packaging significantly inhibited water loss and fruit shrinkage.In fruits stored at 1℃, film packaging delayed the decrease of total soluble solids.titratable acid and vitamin C contents while showed no significant effect on fruit decay,thereby kept the fresh quality.While stored at 20℃ film packaging significantly increased the decay of fruits.this might be related to the accumulation of CO2 and C2H4 with in the packaging bags,which induced physiological disorder and accelerated senescence of fruits.These results indicated that loquat fruits could be stored at 1 ℃ in 0.01 ~0.03mm PE bags wigh good quality for more than 20 days.
