Ginger juice of raw materials and preparation process determines the ginger is difficult to save for a long time, when used for cannot decide amount of using according to the content of active ingredients; Different sources of ginger is used for Chinese medicine yinpian processing is difficult to achieve consistent processing effect.

of ginger in vacuum freezing dryer dry indoor different shelf temperature and vacuum freeze-dried was studied, under the condition of the optimization of ginger juice freeze drying conditions were determined. Set up 6 - ginger juice and soluble ginger juice Ginger hydroxybenzene, 8 - Ginger hydroxybenzene, 10 - Ginger hydroxybenzene, 6 - Ginger ene of phenol content determination method; The ginger juice before and after freeze drying and 6 - within 30 d preservation period Ginger hydroxybenzene, 8 - Ginger hydroxybenzene, 10 - Ginger hydroxybenzene, 6 - Ginger ene of phenol content, volatile content and the change of the total phenol content was studied.

the results showed that the process optimized ginger freeze-dry time shorten; Ginger juice composition is almost the same, before and after freeze-drying gingerol, there was no significant change, the total phenol content content of volatile oil has a significant decline ( P < 0。 05) ; Within 30 d, gingerol, total phenol, volatile oil content is on the decline as a whole.
