摘要
为筛选出较为合适的香椿成熟叶资源化利用加工香椿粉的方法,分别选用冷冻干燥、热风干燥(50,55,60℃)和微波干燥(1,3min,功率3kW)将香椿成熟叶加工成香椿粉,采用CR-400色差仪和气相色谱-质谱联用仪(GC-MS)分别分析加工产品的颜色及挥发性组分,并利用SPSS对挥发性组分进行相关性和聚类分析。结果显示:通过采用冷冻干燥和50℃热风干燥加工的香椿粉产品质量最优,加工产品的挥发性组分与原料相似度分别为0.654,0.591。此外,采用50℃热风干燥具有能耗小、设备简单、技术要求低、耗时较短等优点。
A deep-processing method for Toona sinensis is studied with the aims of harmless treatment and resource reuse. Toona sinensis is processed by vacuum freeze-drying, hot air drying （50, 55, 60 ℃） and microwave drying （1,3 min, power of 3 kW） respectively, and the color and volatile components of products are detected by CR-400 colorimeter and GC-MS, correlation and cluster analysis of volatile components are studied by SPSS. The results indicate that Toona sinensis powder produced by vacuum freeze-drying and hot air drying under 50 ℃ is superior to that in other ways, the similarity of volatile components of processed products and raw materials is 0. 654 and 0. 591 respectively. Besides, it has the advantages of less energy consumption, simple equipment, low cost and short time under 50 ℃ hot air drying.
