Problems solved by technology

[0002] Luo Han Guo is a tropical fruit mainly produced in Guangxi. If no fresh-keeping treatment is carried out during transportation or storage to the north after picking, it is very easy to cause rapid deterioration and rot of Luo Han Guo due to breathing or residual harmful bacteria on the surface.
Most of the existing fresh-keeping methods are refrigeration, but the cost of refrigeration is high, and it is easy to produce cold-resistant pathogenic bacteria

Embodiment 1

[0011] Dissolve 70g of shellac with 100ml of ethanol at 40°C, then add 3g of monoglyceride, 0.01g of tea saponin, 0.05g of penthiopyrad and 0.05g of α-aminoisobutyric acid in sequence, and stir After it is completely dissolved, it is finally diluted to 1000g with water to obtain the Luo Han Guo fresh-keeping coating solution. Put the grosvenor fruit into the grosvenor fruit fresh-keeping coating solution, dip coating, and dry in air to obtain a layer of film on the surface of the grosvenor fruit.

Embodiment 2

[0013] Dissolve 90g of shellac with 150ml of ethanol at 40°C, then add 4g of monoglyceride, 0.03g of tea saponin, 0.02g of penthiopyrad and 0.1g of α-aminoisobutyric acid in sequence, and stir After it is completely dissolved, it is finally diluted to 1000g with water to obtain the Luo Han Guo fresh-keeping coating solution.

Embodiment 3

[0015] Dissolve 100g of shellac with 200ml of ethanol at 30°C, then add 5g of monoglyceride, 0.04g of tea saponin, 0.01g of penthiopyrad and 0.01g of α-aminoisobutyric acid in sequence, and stir After it is completely dissolved, it is finally diluted to 1000g with water to obtain the Luo Han Guo fresh-keeping coating solution.

Abstract

The invention discloses a siraitia grosvenori preservation filming liquid which consists of shellac, glycerol monostearate, tea saponin, penthiopyrad and alpha-amino isobutyric acid, wherein the mass concentration of shellac is 7-10%, the mass concentration of tea saponin is 0.3-0.5%, the mass concentration of penthiopyrad is 0.001-0.004%, and the mass concentration of alpha-amino isobutyric acid is 0.01-0.001%. Through the adoption of the preservative, the freshness cost is lowered, no cold tolerance pathogenic bacterium is generated, growth of bacteria on the surface of siraitia grosvenori is inhibited, and rot is prevented. The surface of the siraitia grosvenori can be smooth and fresh by using the siraitia grosvenori preservation filming liquid, the fruit rot rate is less than 2% after 100 days, and the driage is less than 20%.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to a coating liquid for preservation of Luo Han Guo. Background technique [0002] Luo Han Guo is a tropical fruit mainly produced in Guangxi. If no fresh-keeping treatment is carried out during transportation or storage to the north after picking, it is very easy to cause rapid deterioration and rot of Luo Han Guo due to respiration or residual harmful bacteria on the surface. Most of the existing fresh-keeping methods are cold storage, but the cost of cold storage is relatively high, and cold-resistant pathogenic bacteria are likely to be produced. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fresh-keeping coating liquid for Luo Han Guo and a preparation method thereof. [0004] In order to solve the problems of the technologies described above, the present invention...
