摘要:本研究以金桔为对象，探讨脉冲电场处理对金桔表皮质构及糖浸渍速率的影响。研究发现随着脉冲电场处理脉冲个数增加，糖浸渍速率提高，电场强度1.5 kV/cm时处理4次，每次40个脉冲为最佳电场处理条件，金桔浸糖速率比传统工艺提高78.49%，浸渍时间比传统工艺缩短6～7 d。脉冲电场处理可以明显提高金桔蜜饯咀嚼性、弹性，相比传统工艺弹性提高10.31%～15.33%、咀嚼性提高76.36%～83.33%。

Abstract: The research is mainly focusing on the effects of Pulse Electric Field (PEF) on the Cortical structure and impregnation rate of kumquat. The more the number of PEF treatments is applied,the faster the sugar concentration in the impregnated solution decreases. The results of orthogonal experiment indicated that the best condition is treated 4 times by 1.5 kV/cm electric intensity and 40 pulses,compared with traditional way the impregnation rate increases 78.49%,the immersion time can be reduced by 6～7 days.The experimental results indicated that better resilience and chewiness can be achieved. Compared with the kumquat treated by the traditional way,the properties of PEF treatment which chewing increased 76.36 %～83.33 % and the resilience increased by 10.31 %～15.33 %.
