Problems solved by technology

It can be seen that the temperature during drying has a great influence on the content of mogroside V in Luo Han Guo. Although freeze-drying can better retain active ingredients such as mogroside V, the outer skin of the dried fruit obtained by conventional freeze-drying will have a certain The degree of damage, the shape of the fruit is incomplete, so it cannot be sold as a single dried fruit, and it needs to be further processed into powder or other forms of products for sale

Embodiment 1

[0019] 1) Cleaning: Wash the fresh Luo Han Guo fruit (picked in Yima Village, Longjiang Township, Yongfu County, Guilin City, Guangxi, the content of Mogroside V in the fresh fruit is 1.68% (HPLC));

[0020] 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;

[0021] 3) Freeze-drying: place the finished Luo Han Guo in a freeze-drying equipment, cool down to -50°C, control the cooling process for 3 hours, then raise the temperature to -25°C at a heating rate of 3°C / h, and then increase the temperature at 9°C / h The heating rate is raised to 20°C and kept for 8 hours, and the dried Luo Han Guo is obtained.

[0022] The obtained dried fruit has a complete and bea...

experiment example

[0024] In order to illustrate the advantages of the product obtained by the method of the present invention, the applicant divided the fresh fruit of Monk Fruit from Yima Village, Longjiang Township, Yongfu County, Guilin City, Guangxi (the content of mogroside V in the fresh fruit is 1.68% (HPLC)) into 5 parts. Group (the dosage of each group of fresh fruit is the same as that of 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 :

[0025] 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

[0040] 1) Cleaning: Wash the fresh fruit of Luo Han Guo (picked in Yima Village, Longjiang Township, Yongfu County, Guilin City, Guangxi, the content of Mogroside V in the fresh fruit is 1.62% (HPLC));

[0041] 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;

[0042] 3) Freeze-drying: Place the finished Luo Han Guo in a freeze-drying equipment, cool down to -60°C, control the cooling process at 1.5h, then raise the temperature to -20°C at a heating rate of 1.2°C / h, and then increase the temperature at 10°C / h The heating rate of h is raised to 25°C and kept for 6 hours to obtain the dried Luo Han Guo.

[0043] The obtained dried fruit has a complete and beautiful shape,...

Abstract

The invention discloses a drying method of momordica grosvenori and the momordica grosvenori obtained by using the same. The drying method comprises the steps of: cleaning the fresh momordica grosvenori, deactivating enzyme, putting the enzyme-deactivated momordica grosvenori into a freeze dryer, reducing the temperature from -40 DEG C to -60 DEG C, controlling a temperature reducing process within 1-3h, rising the temperature to -25 DEG C to -15 DEG C by the temperature rising speed rate of 1.2-7.5 DEG C / h, rising the temperature to 20-25 DEG C by the temperature rising speed rate of 3.5-10 DEG C / h, and keeping the temperature for 4-8 hours. Compared with the prior art, the enzyme of the fresh momordica grosvenori is deactivated to restrain the activity in the enzyme, and the momordica grosvenori is dried in a freezing way under a special temperature condition to obtain the dried momordica grosvenori which is integrated in shape and beautiful, and has the same color and luster as thefresh momordica grosvenori; the momordica grosvenori is good in mouthfeel, the special fruity of the fresh momordica grosvenori is kept, and the conservation rate of the momordica glycosides V in thedried momordica grosvenori is high; and the invention is simple and controllable in technology, low in energy consumption, and less in the loss of nutrition constituents in the fresh momordica grosvenori.
