| 摘 要： | 以陕西临潼净皮甜石榴为试材,研究了不同pH值CMC涂膜对石榴果实采后生理指标及贮藏品质的影响。结果表明:石榴在(4.0±0.5)℃条件下贮藏,采用pH值5.0、0.5%CMC溶液涂膜,能有效保持石榴籽粒可溶性固形物含量、总糖含量和可滴定酸含量,减缓果皮相对电导率和褐变指数升高速率,降低果实呼吸速率和腐烂率,抑制果皮抗坏血酸氧化酶(AAO)和多酚氧化酶(PPO)活性,保持果皮过氧化物酶(POD)活性相对较高水平。贮藏120d果实外观色泽鲜艳,籽粒感官品质良好,保鲜效果理想。

| Abstract: | Effects of different pH of CMC coating on postharvest physiological index and storage quality of Shaanxi Lintong sweet pomegranate fruit were studied.The results showed that pomegranate fruit stored at(4.0±0.5)℃ with treatment of pH 5.0,0.5% CMC coating could maintain the soluble solids content,total sugar content and titratable acidity of arils effectively.It could also slow down the rise of the relative conductive rate and browning index of skin,reduce the fruit respiration intensity and rotten rate,inhibit the activities of ascorbic acid oxidase(AAO) and polypenoloxidase(PPO),keep peroxidase(POD) activity at a relative high level.After 120 days of storage,pomegranate fruit still had a good appearance.Its sensory quality was favorable and is idea for fresh-keeping. |
