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

[0010] 95g of shellac, 5g of monoglyceride, 0.02g of tea saponin, 0.01g of penthiopyrad and 0.1g of α-aminoisobutyric acid were uniformly mixed to obtain the Luo Han Guo preservative. When in use, dissolve the Luo Han Guo preservative with a small amount (50-80ml) of ethanol under proper heating (30-45°C), then dilute it with 850g of water, then put the Luo Han Guo into the diluent, dip it, dry it, and put it on the Luo Han Guo A film is obtained on the surface.

Embodiment 2

[0012] 93g of shellac, 7g of monoglyceride, 0.05g of tea saponin, 0.02g of penthiopyrad and 0.01g of α-aminoisobutyric acid were evenly mixed to obtain the Luo Han Guo preservative.

Embodiment 3

[0014] 94g of shellac, 6g of monoglyceride, 0.04g of tea saponin, 0.03g of penthiopyrad and 0.05g of α-aminoisobutyric acid were uniformly mixed to obtain the Luo Han Guo preservative.

Abstract

The invention discloses a siraitia grosvenori preservative which consists of shellac, glycerol monostearate, tea saponin, penthiopyrad and alpha-amino isobutyric acid, wherein the mass concentration of shellac is 5-7%, the mass concentration of tea saponin is 0.02-0.05%, the mass concentration of penthiopyrad is 0.01-0.03%, and the mass concentration of alpha-amino isobutyric acid is 0.1-0.01%. When being used, the siraitia grosvenori preservative is firstly dissolved by using ethanol, and subsequently is diluted by water, and the siraitia grosvenori is soaked in the diluent so as to obtain a layer of film. 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 water retention sterilization filming liquid is good in stability, the siraitia grosvenori is not deteriorated after being preserved for half a year, the surface of the siraitia grosvenori can be smooth and fresh by using the siraitia grosvenori preservative, the fruit rot rate is less than 2% after 100 days, and the driage is less than 13%.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to a monk fruit preservation agent. 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 breathing 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 Luo Han Guo preservative and its application method. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: ...
