specific Embodiment approach 1

[0007] The specific embodiment 1. the preparation of chitosan membrane liquid: take by weighing 10-20g chitosan, dissolve with glacial acetic acid, then add water to swell, add glycerol again, add water to 1L and obtain the chitosan that concentration is 1-2% Membrane fluid. Wherein, the volume percentage of glacial acetic acid is 2%, and the volume percentage of glycerol is 0.5%.

[0008] 2. Selection of melons: Choose late-maturing watermelons with thick skin, tough texture, tight skin and flesh tissue, healthy growth on live vines, and no pests and diseases.

[0009] 3. Harvesting: 10 days before harvesting, spray the chitosan film solution. The harvesting time is selected in the evening on a sunny day. After harvesting, it should be placed in a shade shed. To mat hay, be careful to handle it with care.

[0010] 4. Storage: Put the above-mentioned watermelons in a warehouse at 2-8°C, observe them every 7 days thereafter, and pick out the damaged ones in time.

Abstract

The invention relates to a watermelon fresh-keeping method, and belongs to the field of watermelon fresh keeping. In the prior art, the storage time of the watermelon is relatively short, the general watermelon fresh keeping method can only provide the 1-3 month fresh keeping time, and the user inconveniently eat the watermelon. A purpose of the present invention is to effectively solve the problems in the prior art. According to the present invention, watermelon is adopted as an object, 10-20 g of chitosan is weighed and is dissolved with glacial acetic acid, water is added to swell, glycerol is added, water is supplemented to achieve a volume of 1 L so as to obtain a chitosan film liquid with a concentration of 1-2%, the watermelon with characteristics of late ripeness, thick peel, tough texture, compact peel-flesh organization, healthy growth on the living vine and no pest is selected, the chitosan film liquid is sprayed 10 days before harvesting, the harvested watermelon is placed into a shady shed and solarization is avoided, 10 cm of the watermelon pedicel is retained during the harvesting, hay is padded during the watermelon transportation, the obtained watermelon is placed into a warehouse with a temperature of 2-8 DEG C. observation is performed every 7 days, the relatively-stable temperature and the relatively-stable humidity in the warehouse are maintained during the storage, doors and windows are closed during the day and are opened at night, and the ventilation state is maintained.

Description

technical field [0001] The invention relates to a fresh-keeping method for watermelon. Background technique [0002] Watermelon is a kind of fruit that people love in summer. Watermelon has the effect of cooling and quenching thirst. Watermelon is very nutritious and contains a variety of vitamins, but watermelon Contents of the invention [0003] The object of the present invention is to provide a watermelon with a relatively short preservation time.
