Embodiment Construction

[0022] A) Place the picked Luo Han Guo fresh fruit for 10 days under the condition of natural ventilation and drying.

[0023] B) Wash, and then kill in 100°C water for 30s;

[0024] C) Drill a small hole at the top fruit pedicle of the killed Luo Han Guo and the corresponding bottom fruit navel respectively; the hole diameter is 2mm.

[0025] D) Ultraviolet radiation disinfection;

[0026] E) Use vacuum microwave drying equipment with a vacuum drying chamber, and the microwave frequency is 2500MHz. Place the processed grosvenor fruit in the fruit plate in the vacuum drying chamber, and rotate 360 ​​degrees on the vertical side with the fruit plate. The vacuum degree in the vacuum drying chamber is 0.07kpo. Luo Han Guo drying time is 1.5 hours.

[0027] F) Afterwards, packed in pharmaceutical grade aluminum foil. Fill the bag with nitrogen gas and put in the bagged desiccant.

[0028] One grosvenor fruit is loaded into each packaging bag.

Abstract

The invention discloses a method for preparing high-quality dried momordica grosvenori. The method comprises the following steps: A) performing after-ripening on momordica grosvenori; B) washing the momordica grosvenori and removing water; C) punching; D) ultraviolet disinfection; E) dynamic vacuum microwave drying; F) sealing and packaging. The yellow dried momordica grosvenori produced by the method has bright color like the fresh fruit, so that the stability of natural carotenoid can be ensured, the loss of efficacy and nutrition is greatly reduced; the retention rate of mogroside V is high, and mouthfeel and flavor are close to the fresh fruit. In particular, the sweet taste is pure and cool, and the soaked water is golden yellow and bright. The process is simple and easy to control; the operation process is simple and convenient without repeat; the drying time is short; during the drying process, the method cannot generate toxic and harmful substances; the energy consumption is low. Compared with the normal electrical heating method, the method can save energy for 50% above; compared to the existing microwave drying method, the method can save energy for 40% above. The obtained dried momordica grosvenori is sanitary and clear, low in possibility of getting damp, durable in storage, long in storage time, and good in edible safety.

Description

technical field [0001] The invention relates to the processing of Luo Han Guo, in particular to a method for preparing high-quality dried Luo Han Guo. Background technique [0002] Invention patent Zl201010556001.6 discloses a method of microwave drying Luo Han Guo and Luo Han Guo dried by this method. The method is to wash and kill the Luo Han Guo; then respectively punch a small hole in the top fruit pedicle of the cleaned Luo Han Guo and the corresponding bottom navel; then put the punched Luo Han Guo into the microwave drying equipment , dry at 2400-2500MHz or 915MHz, 50-60°C for 8-10 minutes, then take it out, and place it at 0-4°C to cool down for 3-5 minutes; take it out and put it in a microwave drying equipment and dry it under the same conditions for 8-10 minutes After 10 minutes, take it out, place it at 0-4°C and lower the temperature for 3-5 minutes; repeat the above drying and cooling process for 5-6 times, and it is ready. However, this method is repeatedly ...
