|
| Abstract: |
| Based on the introduction of the principle and the technical points of vacuum freeze drying on Chinese herb processing, the quality control model in the process was built, and the methods to determine the coefficient of the model were analyzed. It is indicated that the method of vacuum freeze drying can effectively prevent the degradation of cure and taste properties and the losing of biochemical active mass during the traditional drying process of Chinese herb. The market prospect of vacuum freeze drying on Chinese herb processing was forecasted while its limitation such as high cost was also discussed. |
