摘　　要：为延长细叶黄皮果的保鲜期,试验以广西崇左市龙州县的细叶黄皮果为原料,采用壳聚糖复合涂膜法对细叶黄皮果进行保鲜,通过测定细叶黄皮果中的维生素C含量、还原糖含量、总酸度、烂果率和失水率等指标来判定保鲜效果。经过单因素实验和正交试验结果得出,细叶黄皮果采用壳聚糖复合涂膜法的最佳配方为壳聚糖2%,山梨酸钾0.05%,脱氢乙酸钠2%,氯化钙6%。此条件下细叶黄皮果可以保鲜15 d,保鲜期比自然条件下延长12 d。In order to prolong the fresh-keeping period of the fine-leaf yellow fruit,the chitosan compound coating method was used to study the fresh-keeping ability of the fine-leaf yellow fruit in Longzhou county,Chongzuo city,Guangxi.The fresh-keeping effect was determined by measuring the vitamin C content,reducing sugar content,total acidity,rotten fruit rate and water loss rate.The results of single factor experiment and orthogonal test showed that the best formula of chitosan composite coating method was chitosan 2%,potassium sorbate 0.05%,sodium dehydroacetate 2%,calcium chloride 6%.Under this condition,the fine leaf yellow fruit could be kept fresh for 15 days,and the shelf life was 12 days longer than that under natural conditions.
