Embodiment 1

[0011] Dissolve 150g of shellac with 200ml of ethanol at 40°C, then add 1g of monoglyceride, 0.03g of erythoxystrobin and 0.02g of aminoxyacetic acid in sequence, stir until completely dissolved, then add 3g of carbonic acid sodium, and finally diluted with water to 1000g to obtain the mango water-retaining and antiseptic coating solution. Mangoes are put into the mango water-retaining and sterilizing coating solution, dipped and dried, and a film is obtained on the surface of the mangoes.

Embodiment 2

[0013] Dissolve 180g of shellac with 220ml of ethanol at 40°C, then add 1.5g of monoglyceride, 0.05g of erythoxystrobin and 0.01g of aminoxyacetic acid in sequence, stir until completely dissolved, then add 5g Sodium carbonate is finally diluted to 1000g with water to obtain the mango water-retaining and sterilizing coating solution.

Embodiment 3

[0015] Dissolve 200g of shellac with 300ml of ethanol at 30°C, then add 2g of monoglyceride, 0.06g of erythoxystrobin and 0.015g of aminoxyacetic acid in sequence, stir until completely dissolved, then add 4g of carbonic acid sodium, and finally diluted with water to 1000g to obtain the mango water-retaining and antiseptic coating solution.

Abstract

The invention discloses a mango water retention sterilization filming liquid which consists of shellac, glycerol monostearate, sodium carbonate, enestroburin, amino oxyl acetic acid and a solvent, wherein the mass concentration of shellac is 15-20%, the mass concentration of glycerol monostearate is 0.1-0.2%, the mass concentration of sodium carbonate is 0.3-0.5%, the mass concentration of enestroburin is 0.003-0.006% and the mass concentration of amino oxyl acetic acid is 0.001-0.002%. Through the adoption of the mango water retention sterilization filming liquid, the freshness cost is lowered, no cold tolerance pathogenic bacterium is generated, inspiration of mango and growth of bacteria on the surface of mango are inhibited, and rot is prevented. The water retention sterilization filming liquid is good in stability, the mango is not deteriorated after being preserved for half a year, the surface of the mango can be smooth and fresh by using the water retention sterilization filming liquid, the fruit rot rate is less than 3% after 100 days, the driage is less than 12%, and the taste is kept fresh.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to a water-retaining and sterilizing coating liquid for mangoes. Background technique [0002] Mango is a tropical fruit mainly produced in Guangxi. If fresh-keeping treatment is not carried out during transportation or storage to the north after picking, it is very easy to cause rapid deterioration and rot of mango 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 mango water-retaining and sterilizing coating solution and a preparation method thereof. [0004] In order to solve the problems of the technologies described above, the present ...
