中文摘要: 以水蜜桃为试验材料，研究壳聚糖、海藻酸钠、普鲁兰多糖浸泡涂膜处理对水蜜桃采后常温下（28 ℃）贮藏品质的影响，定期测定各项生理指标。结果表明，与对照组相比，3 种涂膜处理均能在不同程度上抑制水蜜桃果实的腐烂过程，维持贮藏期果实的品质。海藻酸钠涂膜处理果实能够显著降低果实的腐烂率（比对照组降低40%），同时维持果实硬度、延缓丙二醛含量的上升；壳聚糖涂膜处理在控制果实失重、抑制多酚氧化酶活性方面则优于海藻酸钠和普鲁兰多糖；3 种涂膜处理在维持可溶性固形物含量、抑制呼吸方面无显著差异。1%海藻酸钠涂膜处理由于能够显著抑制果实腐烂，延长果实的货架期，保鲜效果相对最佳。
Abstract:The effects of chitosan，sodium alginate and prulan polysaccharides on the storage quality of honey peach under normal temperature（28 ℃）were studied and the physiological indexes of peaches were determined regularly.The results showed that compared with the control group，3 kinds of coating treatment could inhibit the decay process of peach fruit and maintain the quality of fruit in storage.Sodium alginate coating could significantly reduce the fruit decay rate （40%lower than the control group），maintain fruit hardness and delay the increase of malondialdehyde content.Chitosan coating treatment was superior to sodium alginate and prulan polysaccharide in controlling fruit weight loss and inhibition of polyphenol oxidase activity.There was no significant difference between the 3 coating treatments in maintaining soluble solids content and inhibiting respiration.1%sodium alginate film treatment could significantly inhibit fruit rot，prolong shelf life of fruits and the preservation effect was the best.
