摘　　要：为延长猕猴桃的贮藏期,研究了3种固体酸、3种释放助剂、3种载体对固载二氧化氯保鲜剂气体释放速率的影响,确定了固载二氧化氯猕猴桃保鲜剂的最佳配方,并将该固载二氧化氯保鲜剂应用于猕猴桃贮藏保鲜。结果表明:采用固体酸1和亚氯酸钠反应,并添加助剂3和载体3制备的固载二氧化氯保鲜剂可缓慢平稳释放二氧化氯,释放期可达20d。常温下固载二氧化氯保鲜剂能显著降低猕猴桃的软果率、呼吸强度、可溶性固形物及腐败率,延长猕猴桃的贮藏期,对猕猴桃有较好的保鲜效果。The optimum formula of solid chlorine dioxide preservative for fresh-keeping of kiwi fruit was determined by studying the effect of different solid acids, release additives and carriers on gas release rate of solid chlorine dioxide preservative to prolong the storage period of kiwi fruit. The results showed that the solid chlorine dioxide preservative containing tatraric acid, calcium chloride and active carbon could release chlorine dioxide slowly and stably, and reduce soft fruit rate, respiratory intensity, soluble solid and rotted rate significantly, and its release period could be up to 20 d.
