Abstract

The invention belongs to the technical field of food processing, and particularly discloses a momordica grosvenori drying process and a momordica grosvenori dried product prepared through the momordica grosvenori drying process. The drying process comprises the steps of fruit selection, cleaning, fixation, punching, disinfection, freezing and the like. Compared with the prior art, the process is simple and easy to control, the freeze drying time is short, energy consumption is low, and production efficiency is high. Activity of polyphenol oxidase and the like in momordica grosvenori is restrained through microwave fixation, then, ultraviolet light is adopted for sterilization and disinfection, the storage period of momordica grosvenori freeze-dried superfine powder is effectively prolonged, and using safety and health of the momordica grosvenori freeze-dried superfine powder are ensured; by means of a vacuum freezing sublimation drying process, the problem that pulp and peel are separated due to water loss is avoided, the shape, color, luster, fragrance, taste, nutritive ingredients and the like of momordica grosvenori are well kept, and the momordica grosvenori drying method is worthy of being applied and popularized.
