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
The present invention relates to the preservation method of Citrullus vulgaris.
Background technology
Citrullus vulgaris is a kind of fruit that summer, people liked, Citrullus vulgaris has cool, thirst-quenching effect, and the nutrition of Citrullus vulgaris is very abundant, containing multivitamin, but Citrullus vulgaris
Summary of the invention
The holding time that the invention aims to provide the guarantor of a kind of Citrullus vulgaris is comparatively short, and general Citrullus vulgaris preservation method can only be fresh-keeping 1��3 month, and user eats inconvenience. Fresh method, it can effectively solve the problem that the holding time of Citrullus vulgaris is comparatively short, and general Citrullus vulgaris preservation method can only be fresh-keeping 1��3 month, the shortcoming that user eats inconvenience.
The object of the present invention is achieved like this: (1) weighs 10-20g chitosan, dissolves with glacial acetic acid, then adds water swelling, then glycerol adding, and namely moisturizing obtains the chitosan film liquid that concentration is 1-2% to 1L. Wherein, the volume of glacial acetic acid is 2%, and the percentage by volume of glycerol is 0.5%.
(2) select late-maturing, skin depth, strong but pliable in texture, at healthy growth on rattan of living, Citrullus vulgaris without pest and disease damage; Gathering first 10 days, spray chitosan film liquid, to put in cloudy canopy, be never exposed to the sun after gathering, pedicle of citrullus lanatus (thunb.) mansfeld to stay 10 centimetres, to pad Radix Glycyrrhizae during fortune melon; Above-mentioned Citrullus vulgaris is put in the warehouse of 2��8 DEG C, within hereafter every 7 days, observe once; To keep the temperature and humidity in warehouse relatively stable during storage.
The preservation method of Citrullus vulgaris of the present invention, the method can keep Citrullus vulgaris 3-12 month depositing all without rotten, can both eat Citrullus vulgaris in making user at all seasons.
The preparation of detailed description of the invention 1. chitosan film liquid: weigh 10-20g chitosan, dissolves with glacial acetic acid, then adds water swelling, then glycerol adding, and namely moisturizing obtains the chitosan film liquid that concentration is 1-2% to 1L. Wherein, the volume of glacial acetic acid is 2%, and the percentage by volume of glycerol is 0.5%.
2. select melon: select late-maturing, skin depth, strong but pliable in texture, skin and flesh tissue tight, at healthy growth on rattan of living, Citrullus vulgaris without pest and disease damage.
3. gathering: gather first 10 days, spray chitosan film liquid, collecting time selected in the dusk of fine day, to put in cloudy canopy, be never exposed to the sun after gathering, and pedicle of citrullus lanatus (thunb.) mansfeld to stay 10 centimetres, to pad Radix Glycyrrhizae, note handling with care during fortune melon.
4. storage: put into by above-mentioned Citrullus vulgaris in the warehouse of 2��8 DEG C, observes once, it has been found that picking out in time of damage for hereafter every 7 days.
5. management: keeping the temperature and humidity in warehouse relatively stable during storage, daytime closes the doors and windows, night, door and window, kept ventilating.
