Method for fresh-keeping storage and after-ripening of momordica grosvenori

The invention relates to a method for fresh-keeping storage and after-ripening of momordica grosvenori, which takes harvested fresh momordica grosvenori as a raw material and comprises the following steps: (1) selecting momordica grosvenori and warehousing; (2) fresh keeping: spraying a mixed aqueous solution of epsilon-polylysine hydrochloride and calcium propionate according to a certain time interval, and starting ozone circulation; (3) after-ripening: in a warehouse, raising the temperature to 22-26 DEG C at the temperature raising rate of 0.15-0.35 DEG C/h, keeping the relative humidity at 80-90% in the temperature raising process, keeping the relative humidity at 70-80% after the temperature is reached, ventilating once every 22-26 hours, and keeping the normal concentration of oxygen; alkali liquor is used for absorbing and adjusting the concentration of carbon dioxide, an ethephon aqueous solution is evenly sprayed once every 4-6 days, and the after-ripening process lasts for 15-30 days.
