摘要
在牡丹花红色素理化性质的研究基础上,进行了牡丹花预处理、预冻试验,研究了预处理方式对牡丹花冷冻干燥的影响。利用LG0.2型真空冷冻干燥机进行了牡丹花的真空冷冻干燥试验研究,得到最佳的干燥工艺为:用10%的柠檬酸无水乙醇溶液处理10min,冰箱慢冻4h,然后液氮速冻5min、升华干燥6h,然后解析干燥10h。
Based on the physical and chemical properties of the pigment of peony flower, the pre-processing experiments and pre-freezing before drying were conducted. The effect of pattern of pre-processing and pre-freezing on the following peony drying was studied. Freeze-drying experiments after pre-treatments were carried out in a LG - 0. 2 freezing dryer. The curve of peony freeze-drying was gotten. The sample of drying flower is similar to a fresh flower.
