Embodiment 1
[0024] 1) Cleaning: Wash the fresh Luo Han Guo fruit (the content of mogroside V is 1.68% (HPLC, the same below));
[0025] 2) Finishing: Get the washed Momordica grosvenori completely soaked in 90 DEG C of killing solution for finishing 10min, and wherein fixing solution adopts following method to prepare: take pure water, add the ginger (ginger smashed) that is equivalent to pure water weight 0.1% (weight). ), adjust the pH value of the solution to 5.5 with citric acid to get final product;
[0026] 3) Punching: Punch a small hole with a diameter of 5 mm at the top fruit pedicle of the finished Luo Han Guo and the corresponding bottom fruit navel respectively;
[0027] 4) Microwave drying: Put the perforated Luo Han Guo into the microwave drying equipment, adjust the working frequency to 915MHz, temperature 60°C, input apparent power ≤ 100kw, output power ≤ 60kW and dry for 10min, then take it out and put it in the Lower the temperature at 2°C for 3 minutes; then take it ou...
experiment example
[0030] In order to illustrate the advantages of the product obtained by the method of the present invention, the applicant divided the fresh Luo Han Guo fresh fruit from Yima Village, Longjiang Township, Yongfu County, Guilin City, Guangxi (the content of mogroside V in the fresh fruit is 1.68%) into 5 groups (each The amount of fresh fruit in the group is the same as the amount in Example 1) to make dried fruits with different processes, and then compare them with the appearance, color, mogroside V content and mouthfeel of the dried fruits obtained in this embodiment, as follows:
[0031] The first group: the freeze-drying group, the fresh fruit is washed and dried in the air, and the fruit is placed in a freeze-drying device, and freeze-dried at a low temperature below 0°C for 24 hours. The obtained dried fruit has serious appearance damage, incomplete shape and unattractive appearance, green color, water content of 3.0%, and content of mogroside V in the dried fruit of 6.17%...
Embodiment 2
[0047] 1) Cleaning: Wash the fresh Luo Han Guo (the content of mogroside V is 1.68%);
[0048] 2) Finishing: get the washed Momordica grosvenori completely soaked in 95 DEG C of killing solution for 8 minutes, wherein the fixing solution adopts the following method to prepare: get pure water, add ginger (smashed ginger) equivalent to 0.3% (weight) of pure water weight ), adjust the pH value of the solution to 6.0 with citric acid to get final product;
[0049] 3) Hole punching: punch a small hole with a diameter of 3 mm at the top fruit pedicle of the finished Luo Han Guo and the corresponding bottom fruit navel respectively;
[0050] 4) Microwave drying: Put the perforated Luo Han Guo into the microwave drying equipment, adjust the operating frequency to 2450MHz, temperature 55°C, and dry for 8 minutes under the conditions of input apparent power ≤ 100kw and output power ≤ 60kW, then take it out and put it in Cool down at 0°C for 5 minutes; then take it out and put it in mic...
