以九月底采收的白花莲藕为材料，清洗脱皮后经Ｈ２ＰＯ４，Ｎａ２ＳＯ３浸泡处理，ＨＰＥ薄膜袋密封包装，并置于冷库及常温库内贮藏，贮藏期间研究其生理变化实验结果表明：脱皮莲藕在冷藏期间呼吸强度、乙醇含量、果胶甲脂酶活性逐渐上升，而多酚氧化酶及过氧化物酶活性逐渐降低，脱皮与未脱皮莲藕贮藏生理有一定的差异贮藏温度对脱皮莲藕生理有较大的影响，随贮藏温度升高，脱皮莲藕加速衰老 The white lotus root lotus root harvested at the end of September was used as a material, washed and peeled, then soaked in H2PO4 and Na2SO3, sealed and packed in HPE film bag, and placed in a cold storage room at room temperature for storage. During storage, the physiological changes were studied  The experimental results showed that: During cold storage, the respiration rate, ethanol content and pectin methylase activity gradually increased while the activities of polyphenol oxidase and peroxidase decreased gradually. There was a certain difference in storage physiology between peeling and non-peeling lotus root storage temperature. Have a greater impact, with the storage temperature, peeling lotus root accelerated aging
