Abstract

The invention discloses freeze-dried siraitia grosvenorii slices and a preparation method thereof and belongs to the technical field of food processing. The freeze-dried fructus siraitiae slices are prepared through processes of selecting, slicing, carrying out fixation, naturally drying by air, pre-freezing, carrying out secondary freezing, deeply freezing and the like. Compared with the prior art, the method has a simple and easily-controlled process, short freezing and drying time, low energy consumption and high production efficiency; a hot water fixation technology is adopted so that the activity of enzymes including polyphenol oxidase and the like in siraitia grosvenorii peels is deactivated; three times of freezing processes are adopted so that moisture in siraitia grosvenorii is volatilized in sequence and the separation of peels and pulp, caused by moisture drying, is avoided; meanwhile, the color and luster, aroma, taste, nutrient components and the like of the siraitia grosvenorii are kept very well.
