On January 17, 2019, the Ministry of Agriculture and Rural Affairs of the People's Republic of China officially approved the registration and protection of geographical indications of agricultural products for "Wangjialu Red Oil Chine...

Embodiment 2

[0040] The present embodiment proposes a kind of fresh-keeping method of perishable vegetable Chinese toon: comprise the following steps,

[0041] (1) Choose fresh and tender Chinese toon as raw material, and clean the Chinese toon with ultrasonic cleaning for 30 seconds with clean water;

[0042] (2) Blanch the washed Chinese toon in 2.0% vitamin C solution at 95°C for 5-15 seconds;

[0043](3) The treated Chinese toon was treated with 1-methylcyclopropene at a concentration of 0.6mg / L to carry out airtight fumigation treatment at 4°C for 7h,

[0044] (4) Bundle the treated Chinese toon, dip the root in egg liquid, wrap it with 0.01mm PVC film and use 40W with an intensity of 400μW / cm 2 UV irradiation for 10min;

[0045] (5) Finally, put the wrapped Chinese toon on 0.5-0.8mm thick kraft paper and pack it with ethylene absorbent. The mass ratio of ethylene absorbent to Chinese toon is 1:50-60. Refrigerate at 90% humidity.

Embodiment 3

[0047] The present embodiment proposes a kind of fresh-keeping method of perishable vegetable Chinese toon: comprise the following steps,

[0048] (1) Choose fresh and tender Chinese toon as raw material, and clean the Chinese toon by ultrasonic cleaning for 25 seconds with clean water;

[0049] (2) Blanch the washed Chinese toon in 100°C, 1% by mass sodium carbonate solution for 5-15s;

[0050] (3) The treated Chinese toon was treated with 1-methylcyclopropene at a concentration of 0.8 mg / L for airtight fumigation at 4°C for 7 hours,

[0051] (4) Bundle the treated Chinese toon, dip the root in egg liquid, wrap it with 0.01mm PVC film and use 40W with an intensity of 400μW / cm 2 UV irradiation for 10min;

[0052] (5) Finally, put the wrapped Chinese toon on 0.5-0.8mm thick kraft paper and pack it with ethylene absorbent. The mass ratio of ethylene absorbent to Chinese toon is 1:50-60. Refrigerate at 95% humidity.

Abstract

The invention provides a preservation method for perishable vegetable cedrela sinensis. The preservation method comprises the following steps: quickly cleaning cedrela sinensis with clear water for 20-30 seconds; blanching the cleaned cedrela sinensis in 0.5%-2.0% blanching solution at 95-100 DEG C for 5-15 seconds; fumigating the treated cedrela sinensis sprouts with 1-methyl cyclopropene, bundling the treated cedrela sinensis, dipping the roots of the cedrela sinensis with egg liquid, wrapping the cedrela sinensis with a PVC film, irradiating the cedrela sinensis with ultraviolet light; finally putting the wrapped cedrela sinensis on kraft paper in 0.5-0.8mm thickness, conducting packaging, putting an ethylene absorbent into the package, and conducting refrigerated storage. According tothe preservation method, the preservation period of the cedrela sinensis is prolonged, and the unique fragrance, color and texture of the cedrela sinensis in the storage period are kept, thereby meeting the market requirements, and prolonging selling period of the cedrela sinensis on the markets.

Description

technical field [0001] The invention relates to the field of vegetable storage, in particular to a fresh-keeping method of perishable vegetable Chinese toon. Background technique [0002] Chinese toon is a kind of woody vegetable that is popular among consumers. Its fresh and tender stems and leaves are edible and delicious. The young leaves of Chinese toon are rich in protein, sugar, vitamin B, vitamin C, carotene, volatile oil and phosphorus. Minerals such as iron. Fresh Chinese toon buds have a short harvest period, strong seasonality, high water content, high post-harvest respiratory intensity, and vigorous vitality. If they are not kept fresh in time, they will appear wilting, dehydration, rot and deterioration, and leaves if they are placed at room temperature for 1-2 days. Quality deterioration such as shedding, loss of its unique nutritional and flavor value, loss of commerciality. Therefore, the application of post-harvest preservation technology for fresh Chinese...
