摘要
[目的]探讨微波预干燥处理对真空冷冻干燥佛手(FRUCTUS CITRI SARCOKACTYLIS)的影响。[方法]以真空冷冻干燥总时间和成品复水率为主要指标,采用微波技术对佛手进行预干燥处理,并采用L9(33)正交试验对预处理条件进行优化。[结果]微波预干燥处理佛手的最优工艺条件为:微波功率420 W,物料厚度7 mm,物料转换点含水量40%,该条件下的真空冷冻干燥总时间为9.4 h。[结论]微波预处理可明显缩短冻干总时间,提高成品复水率。
[Objective] The aim was to discuss the effect of microwave pretreatment on vaccum freeze-drying of bergamot slices.[Method] Taking vacuum freeze-drying time and rehydration rate as main indexes,pre-drying processing on bergamot was carried out based on microwave technology and through L9（33） orthogonal experiments,the optimum pre-processing parameters was optimized.[Result] The optimal conditions of microwave pre-processing were as follows： microwave power was 420 W,material thickness was 7 mm and conversion moisture content of material was 40%.Under these conditions,the whole vaccum freeze-drying time was 9.4 h.[Conclusion] Microwave pre-processing can shortened the vaccum freeze-drying time and improved rehydration rate of finished products significantly.
