Problems solved by technology

The advantage of hot air drying is low energy consumption, but the disadvantage is serious loss of nutrients, shrinkage of the surface of Luo Han Guo, poor shape, discoloration, etc.
Microwave vacuum drying, the color of the dried product is better than hot air drying, but the loss of nutrients is more serious

Abstract

The invention discloses fructus momordicae freeze-dried micropowder. The fructus momordicae freeze-dried micropowder is prepared through the steps of fruit sorting, cleaning, slicing, fixation, natural air drying, prefreezing, secondary freezing, deep freezing, superfine grinding and the like. Compared with the prior art, according to the method, the technology is simple and easy to control, the freeze-drying time is short, energy consumption is low, and the production efficiency is high; a hot-water fixation technology is adopted, activity of enzymes of polyphenol oxidase and the like in peel of fructus momordicae can be passivated, fructus momordicae can be sterilized, and it is guaranteed that eating is safe and hygienic; by means of the three-time freezing technology, moisture in fructus momordicae is subjected to orderly sublimation drying, and peel and pulp separation caused by moisture drying is avoided; meanwhile, the color, fragrance, taste, nutritional ingredients and the like of fructus momordicae are well maintained; after the fine powder is obtained, the use rate of fructus momordicae is greatly increased, absorption is enhanced, the taste is improved, and application is wider.
