摘  要:
Based on the physical and chemical properties of the pigment and the mechanism of color transformation in the courseof peony dryness, the pre-processing experiments and pre-freezing were conducted. The effect of pattern of pre-processing andpre-freezing on peony drying was studied. Afterwards freeze-drying experiments were also carried on in LG-0.2 freezing dryer.The optimum freeze-drying technologies and freeze-drying process curve of peony in different drying conditions were obtained.The better product of dried peony is obtained,too.
