摘　　要：研究了不同浓度氯化钙处理的复合保鲜垫纸对“蓝美1号”蓝莓采后品质的影响。分别采用1%、0.5%氯化钙处理保鲜垫纸,并将其垫在聚乙烯蓝莓盒中,以未垫保鲜垫纸的蓝莓为对照,于模拟5—6月的天气条件下(28℃,相对湿度75%)贮藏6 d,观察分析蓝莓果实腐烂率、失重率、硬度、可溶性固形物含量、VC含量、花色苷含量等采后感官、理化、营养指标的变化。结果表明:1%氯化钙保鲜垫纸处理组有较好的保鲜效果,贮藏6 d时,其果实腐烂率为66.59%,失重率为10.22%,均显著低于对照组(P<0.05);硬度为0.58 kg·cm^(-2),可溶性固形物含量为8.75%,VC含量为8.66μg·g^(-1),花色苷含量为1.92 mg·g^(-1),均高于对照组。本试验结果可以为蓝莓保鲜提供一种廉价、实用的方法。The effect of preservation paper with different concentrations of calcium chloride on the postharvest quality of‘Lanmei No.1’blueberry was studied.The paper was treated with 1%and 0.5%calcium chloride,respectively,and placed in a polyethylene blueberry box.The paper and blueberries were stored for 6 days under simulated weather conditions in May and June(28℃,75%relative humidity).The postharvest sensory,physical,chemical and nutritional indexes,such as decay rate,weight loss rate,hardness,soluble solids,VC content and anthocyanin were observed and analyzed.The results showed that 1%calcium chloride preservation paper had good preservation effect.The decay rate of 1%calcium chloride preservation paper was 66.59%,and the weight loss rate was 10.22%at the 6th day of storage,both of which were significantly lower than those of the control group.The hardness was 0.58 kg·cm^(-2),soluble solid content was 8.75%,VC content was 8.66μg·g^(-1),and anthocyanin content was 1.92 mg·g^(-1),which were all higher than the control group.The results suggested a cheap and practical method for the preservation of blueberries.
