Problems solved by technology

[0002] Mango is a tropical fruit in the south. 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 mangoes due to breathing or harmful bacteria remaining 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 100g of shellac with 200ml (40°C) ethanol first, then add 0.1g of α-aminoisobutyric acid, stir and mix until completely dissolved, add water to dilute to 1000g, and obtain mango fresh-keeping coating agent.

Embodiment 2

[0013] Dissolve 150g of shellac with 300ml (35°C) ethanol first, then add 0.05g of α-aminoisobutyric acid, stir and mix until completely dissolved, add water to dilute to 1000g, and obtain mango fresh-keeping coating agent.

Embodiment 3

[0015] Dissolve 200g of shellac with 400ml (40°C) ethanol first, then add 0.01g of α-aminoisobutyric acid, stir and mix until completely dissolved, add water to dilute to 1000g, and obtain mango fresh-keeping coating agent.

[0016] When in use, the mangoes are dipped in the fresh-keeping coating agent, dipped and dried, and a layer of film is obtained on the surface of the mangoes.

Abstract

The invention discloses a mango preservation film coating agent which is prepared from lac, alpha-aminoisobutyric acid and a solvent, wherein the mass percent of the lac is 10-20%, and the mass percent of the alpha-aminoisobutyric acid is 0.01-0.001%. The preservation film coating agent is prepared by dissolving the lac in the ethanol, adding the alpha-aminoisobutyric acid and diluting with water. The preservation film coating agent can lower the preservation cost, and does not generate cold-resistant pathogens. By using the preservation film coating agent, the mango has smooth surface; and after 100 days, the rotting rate is less than 3%, and the water loss is less than 28%.

Description

technical field [0001] The invention belongs to the field of fruit fresh-keeping, and in particular relates to a mango fresh-keeping coating agent. Background technique [0002] Mango is a tropical fruit in the south. If no fresh-keeping treatment is carried out during the transportation or storage process to the north after picking, it is very easy to cause rapid deterioration and rot of mango due to breathing or harmful bacteria remaining 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 mango fresh-keeping coating agent and its application method. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions:...
