【摘要】 以枇杷为材料,研究添加0.04%(以膜基质干重计)低浓度银纳米颗粒(silver nanoparticles,AgNPs)的鱼鳞明胶-琼脂复合膜包装的保鲜效果,测定贮藏期间枇杷果实生理指标的变化,并与鱼鳞明胶-琼脂复合膜、泡沫网套和PE保鲜袋包装进行对比。结果表明,与3组对照相比,添加AgNPs的鱼鳞明胶-琼脂复合膜包装能有效降低枇杷果实的腐烂率和失重率,抑制硬度的下降,延缓VC、还原糖和可溶性固形物含量的降低。可见,添加0.04%(以膜基质干重计)低浓度AgNPs的鱼鳞明胶-琼脂复合膜对枇杷具有良好的保鲜效果。更多还原

【Abstract】 The effect of fish scale gelatin-agar composite film incorporated with 0.04% low concentration of silver nanoparticles(AgNPs) packages on preservation quality of loquat fruits was investigated,and the changes of physiological indexes of loquat fruits were measured during the storage.Compared with foam fruit net packages,PE packages and fish scale gelatin-agar composite film packages,the fish scale gelatin-agar composite film incorporated with AgNPs packages could significantly reduce the decay and weight loss of loquat fruits,inhibit the loss of firmness,delay the reducing of vitamin C,reducing sugar and total soluble solids.Therefore,the fish scale gelatin-agar composite film incorporated with low concentration of silver nanoparticles could improve the preservation quality.更多还原
