| 摘 要： | 研究(22±2)℃的室温条件壳聚糖、甘草提取液及其复合物3种保鲜处理对采后莱阳梨果实生理生化变化的影响。结果表明：3种保鲜处理均可显著抑制莱阳梨果实的呼吸强度，降低梨果实质量损失率，减少果实腐烂率，延缓VC、可滴定酸及可溶性固形物的降解(P＜0.05)。

| Abstract: | The effects of chitosan, licorice extract and their mixture on physiological and biochemical changes of Laiyang pear fruits during at room temperature ( (22 ± 2 ) ℃) were investigated. The results showed that all the three preservative treatments could significantly (P＜ 0.05) inhibit the respiration intensity, decrease weight loss rate and decay rate, and delay the reduction of vitamin C, titratable acidity and soluble solids when compared with the control group. |
