摘要:

以壳聚糖、ClO2 和CaCl2 三种物质的复合涂膜剂对超藤葡萄进行涂膜,研究其对葡萄贮藏品质和生理代谢的影响。结果表明:壳聚糖、ClO2 和CaCl2 复配涂膜处理葡萄后,不同程度地提高了果实的硬度和好果率,降低葡萄褐变指数;以优选配方5(1.5g/100mL 壳聚糖+0.5g/100mL CaCl2 混合液浸泡2min 后装袋,再以0.3g/kg 葡萄的ClO2 薰蒸)处理可以减少贮藏期间葡萄中可溶性糖、VC 和可滴定酸的损失,有效抑制POD、PPO 活性和MDA的积累,提高SOD 活性。优选配方5 可以作为葡萄保鲜剂进一步检验推广。

Abstract:

To achieve better fresh-keeping of the fruits of Vitis vinifera L. cv. Chaoteng (Chaoteng grape), chitosan coating combined with chlorine dioxide fumigation was used to treat them. Results showed that the treatment increased the firmness and good-fruit rate and lowered the browning index of Chaoteng grapes to a certain extent. Treatment with a coating containing 1.5% (g/100 mL, final concentration) chitosan and 0.5 g/100mL calcium chloride followed by chlorine dioxide fumigation at 0.3 g/kg fruit weight dosage reduced the loss of soluble sugars, vitamin C and titritable acids, effectively suppress the activities of POD and PPO and the accumulation of MDA and increased the activity of SOD in Chaoteng grapes.

Key words: grape, chitosan coating, storage quality, physiological metabolism
