摘要: 以“白凤”水蜜桃为试材,研究壳聚糖涂膜对冷藏白凤水蜜桃品质变化的影响。结果表明:白凤水蜜桃贮藏在1±0.5℃低温下时,1.0%壳聚糖涂膜处理可以抑制呼吸强度、多酚氧化酶(PPO)活性及过氧化物酶(POD)活性,还原糖和可溶性固形物含量较低,总酸和总糖含量较高。

Abstract: The effects of chitosan coating on the quality of “Baifeng” peach fruits stored at 1±0.5℃ were studied. The results showed that 1% chitosan coating was effective to inhibit the increase of respiratory rate, polyphenol oxidanse (PPO), peroxidase (POD) activities, and to keep the content of reducing sugar, and soluble solids at low level with titratable acid, total sugar at high level.
