preparation example Construction

[0031] In another technical solution, the preparation method of the first fresh fresh liquid comprises the steps of:

[0032] a) Dissolving 5-10 parts by weight of chitosan in a 200 parts by weight of the volume fraction of 1% acetic acid distilled aqueous acetic acid, heating and stirring the chitosan to dissolve uniform, obtain chitosan solution;

[0033]b) Add 3-5 parts by weight of polyvinyl alcohol to the chitosan solution, 5-10 parts by weight of the modified diatomite powder, 1-5 parts by weight of fungicide, 0.5-3 parts by weight of resveratrol, 1-3 parts by weight of citric acid, mix well, and obtained the first fresh fresh liquid.

[0034] The present invention utilizes resveratrol to reduce mango's breathing strength, reduce the amount of breathing and ethylene, and maintain high activity of superoxide dismutase, reduce the formation of maloxal, inhibit the growth of corrupt bacteria, and extend mango. Preservation time; use citric acid to slow down mango peaks, the pea...

[0041] A method of extending mango storage, including the following steps:

[0042] 1) Pick 7-8 mature mango, select uniform size, no pests and mechanical damage, use water to clean, and obtain pretreatment mango;

[0043] 2) Spray the first fresh fresh liquid in the surface of the pre-treatment mango, and then at a temperature of 25 ° C, the relative humidity of 50% is air dry in the constant temperature and humidity tank of the temperature, and the first fresh liquid is formed into a film and the moisture of the membrane is reduced to 100%. Time, take it out, get a process of processing mango;

[0044] 3) Spray hydrogen release powder on the surface of the mango, sprayed the second fresh fresh liquid, then at a temperature of 20 ° C, the relative humidity of 50% is air dried, and the second fresh liquid is formed into a film. When the moisture of the membrane body is reduced to 85%, the package is removed and placed in an environment of 5 ° C, humidity is 85%, that is,.

Abstract

The invention discloses a method for prolonging the storage period of mangoes, which comprises the following steps: 1) picking mangoes which are 70-80% mature, selecting fruits which are uniform in size, free from diseases and insect pests and free from mechanical damage, and cleaning the selected fruits with clear water to obtain pretreated mangoes; 2) spraying a first fresh-keeping solution on the surface layer of the pretreated mango, then air-drying in a constant-temperature and constant-humidity chamber with the temperature of 25 DEG C and the relative humidity of 50%, and taking out when the first fresh-keeping solution forms a film and the moisture of the film body is reduced to 110-120%, so as to obtain primarily treated mango; and (3) spraying hydrogen slow-release powder and second fresh-keeping liquid on the surfaces of the primarily treated mangoes, then air-drying in a constant-temperature and constant-humidity box with the temperature of 20 DEG C and the relative humidity of 50%, taking out and packaging when the second fresh-keeping liquid forms a film and the moisture of the film body is reduced to 85-90%, and storing in an environment with the temperature of 5-8 DEG C and the humidity of 85-90%. The method has the characteristics of prolonging the storage time of the mangoes, reducing the nutrient loss of the mangoes in the storage period and the like.

Description

Technical field [0001] The present invention belongs to the field of fruit preservation. More specifically, the present invention relates to a method of extending mango storage. Background technique [0002] Mango is rich in protein, minerals, carbohydrates, vitamins, fat, etc. Mango is harvested under the high temperature conditions of summer, which belongs to the respiratory transition. The fruit is very easy to scribble after normal temperature, resulting in the rotten deterioration in the reservoir process, which seriously affects mango transportation and export. The application number is 201910677540.6, and the present invention is a fruit storage preservation method discloses soaking fruit in a hydrogenated water solution to achieve extended fruit preservation time. However, the ability to soak fruit soak in a hydrogenated water solution is effective, and hydrogen is exhausted in the fruit, so that hydrogen is difficult to function for a long time. Therefore, a mango preser...
