Problems solved by technology

Although the conventional polyethylene film can protect the curd to a certain extent and prevent water loss, it is easy to form condensation inside the film with the fluctuation of the ambient temperature during the circulation process, and gather into water droplets in severe cases. Favorable conditions for the proliferation of pathogenic bacteria
At present, there is no fresh-keeping technology system to control e-commerce sales of broccoli at home and abroad

Embodiment 1

[0027] Select a broccoli base with excellent growth, and spray 30mg / L of 6-BA solution on the surface of broccoli buds with a sprayer 6 hours before harvesting, and start harvesting when there is no sign of moisture on the bud surface; select uniform size (201- 300g), no pests, no mechanical damage, tight curds, green broccoli as the material, put them into a fresh-keeping bag in a single way, and the fresh-keeping bag is an ordinary fresh-keeping bag purchased in a supermarket; put 5g of ethylene into the fresh-keeping bag to absorb Among them, the ethylene absorbent is made by absorbing saturated potassium permanganate solution by vermiculite, putting it into air-permeable paper bag after drying, and sealing it; 2 +8%CO 2 , sealed; take 2 broccoli heads as a unit, put them into a foam box with bubble bags, place them on a microcomputer-controlled vibration table, and simulate road transportation at 25°C;

Embodiment 2

[0032] Select a broccoli base with excellent growth, spray 20mg / L 6-BA on the broccoli buds with a sprayer 8 hours before harvesting, and start harvesting when there is no sign of moisture on the surface of the buds; select uniform size (201-300g), No pests and diseases, no mechanical damage, tight curds, green broccoli as materials, and put them into antibacterial fresh-keeping bags in a single way. The preparation method of the antibacterial fresh-keeping bags is: use 0.025mm thick polyethylene rate film as the outer layer , and then use a single-layer non-woven fabric as a carrier, coat a layer of chitosan solution with a mass concentration of 1% on the non-woven fabric, use it as the inner layer after air-drying, and heat-seal it twice to obtain an antibacterial fresh-keeping bag ; Put into 5g ethylene absorbent in the above-mentioned antibacterial fresh-keeping bag, this ethylene absorbent absorbs saturated potassium permanganate solution by vermiculite, pack into air-perm...

Embodiment 3

[0037] Select a broccoli base with excellent growth, spray 40mg / L 6-BA on the broccoli buds with a sprayer 10 hours before harvesting, and start harvesting when there is no sign of moisture on the surface of the buds; select a uniform size (201-300g), No pests and diseases, no mechanical damage, tight curds, green broccoli as materials, and put them into antibacterial fresh-keeping bags in a single way. The preparation method of the antibacterial fresh-keeping bags is: use 0.025mm thick polyethylene rate film as the outer layer , and then use a single-layer non-woven fabric as a carrier, coat a layer of chitosan solution with a mass concentration of 2% on the non-woven fabric, use it as the inner layer after air-drying, and heat-seal twice to obtain an antibacterial fresh-keeping bag Put into 12g ethylene absorbent in the above-mentioned antibacterial fresh-keeping bag, this ethylene absorbent absorbs saturated potassium permanganate solution by vermiculite, pack into fresh-kee...

Abstract

The invention provides a fresh-keeping method for broccoli sold by e-commerce, which is characterized in that it comprises the following steps: spraying the broccoli with a benzyl adenine solution of 20-40 mg / L concentration 6-10 hours before harvesting; Broccoli is independently packaged with a fresh-keeping bag; ethylene absorbent is placed in the above-mentioned fresh-keeping bag; O is passed into the above-mentioned fresh-keeping bag. 2 and CO 2 Gas, then seal the fresh-keeping bag; put the sealed fresh-keeping bag into the foam box. The technical solution provided by the invention is simple in operation and low in cost, and is favorable for popularization and application. By prolonging the preservation time of broccoli during transportation, the purpose of prolonging sales radius and balancing market supply can be achieved, thereby effectively improving economic benefits.

Description

technical field [0001] The invention belongs to the field of fresh-keeping of vegetables, and in particular relates to a fresh-keeping method for broccoli sold by e-commerce. Background technique [0002] Broccoli, also known as green cauliflower, broccoli, etc., belongs to Brassica oleracea Brassica species. Broccoli is rich in nutrition, which mainly contains carbohydrates, proteins, carotene, various vitamins and other nutrients, which can enhance the detoxification ability of the liver, improve the body's immunity, and have anti-tumor, antibacterial, anti-oxidation and other properties. Pharmacological activity, known as "vegetable crown". However, broccoli flower buds have very strong respiratory metabolism, tender and juicy tissues, and are prone to chlorosis, flowering and browning. In addition, since the surface of broccoli basically has no protective layer, it is very easy to lose water and wilt and reproduce in large numbers. Therefore, it is necessary to delay ...
