| 摘 要： | 研究了以草酸(OA) 为主剂, 二氧化氯(ClO2 ) 、氯化钠(NaCl) 等为辅剂的清洗剂10.0g·L-1OA + 10.0 g·L-1NaCl + 9 mg·kg-1ClO2 + 0.02%吐温-20对红富士苹果的清洗效果及洗后对果实贮藏品质的影响。结果表明: 草酸复合清洗剂对红富士苹果表面的农药、重金属、菌落的清除效果好, 且经该清洗剂清洗后的果实在(0 ±1) ℃冷藏, 贮藏品质高于对照, 延缓果实硬度的下降, 推迟呼吸高峰和乙烯释放高峰的到来时间, 降低乙烯释放量, 延缓可滴定酸、可溶性固形物的降解速度, 并有降低失重率和腐烂率的作用。

| Abstract: | In the present study, the effects of oxalic acid compound agent were investigated on washing efficiency and storage quality of fruits of app le Red Fuji. This compound is a mixture composed of 10.0 g·L-1 oxalic acid, 10.0 g·L-1 sodium chloride, 9 mg·kg-1 chlorine dioxide and 0102% Tween-20. The acid compound cleaning agent on washing was much more efficient than the control on clearing pesticides, heavy metals and colonies from fruit surface. Compared with control, the decrease of flesh firmness, respiratory peak and ethylene released peak were markedly delayed in treated fruits and stored in cool storage conditions. Level of ethylene released from treated fruitswas significantly lower than that of control fruits. Treatment of this compound was also found to delay degeneration of titrate acid and total soluble solid of the stored fruits, and reduce rates of weightlessness and decay of fruits. In conclusion, usage of oxalic acid compound as a washing agent can greatly imp rove quality of stored apple fruits. |
