Example Embodiment

[0015] Example 1:

[0016] 1. Harvesting. Choose fine weather in the morning after the dew is dry, before 9 a.m. and in the evening to harvest. The diameter of asparagus should be 0.9-1.8 cm, the length should be ≥27 cm, the maturity should meet the requirements, the shoots should be straight, and the shoots should not open buds. Handle with care when harvesting, and try to avoid mechanical damage. The incision should be as flat as possible.

[0017] 2. Packing. The harvested asparagus is directly placed in a well-ventilated plastic box with soft paper on the bottom layer.

[0018] 3. Transportation. Use refrigerated trucks to transport to the pre-cooling warehouse as soon as possible.

[0019] 4. Pre-cooling. At least 1 day before the asparagus storage, reduce the storage temperature to 0-1 ℃. After the asparagus is put into storage, the temperature of the asparagus should be reduced to 1-3℃ within 4 hours.

[0020] 5. Selection and processing. In the warehouse at 1-5℃, remove th...

Example Embodiment

[0027] Example 2:

[0028] The selected and processed green asparagus is treated with 0.6% sodium diacetate solution, and after cooling, it is put into a polyethylene fresh-keeping bag containing 30% EVA and a single-sided thickness of 50 microns, filled with ozone gas once every 2 days, and the treatment concentration is 4ppm, other operation and technical requirements are the same as in Example 1.

Example Embodiment

[0029] Example 3:

[0030] The selected and processed green asparagus is treated with 0.4% sodium diacetate solution, and after cooling, it is put into a polyethylene fresh-keeping bag containing 5% food grade non-drip agent and a thickness of 60 microns on one side, and filled with ozone gas once every 3 days , The treatment concentration is 6ppm, and other operation and technical requirements are the same as in Example 1.

Abstract

The invention relates to the storage, transportation, circulation and sale of green asparagus, which in detail is a fresh-keeping technique for green asparagus. Packing the green asparagus with condensation resistant agent and moisture bag after the green asparagus being picked up, and combing the ozone treatment, sodium acetate immersing treatment or placing hygroscopic material to keep fresh for the storage and transportation. The invention can solve the problem of aging, mould, soft rotting and condensation in the bag after the green asparagus be picked up, and characterized by long fresh-keeping period, high edible safety of the used antistaling agent for preservation, no residual of the antirotting action and good accordance with the demand for safe modern foodstuff.

Description

(1) Technical field [0001] The invention belongs to post-harvest fresh-keeping technology of vegetables, in particular to a fresh-keeping method for storage, transportation and distribution of green asparagus. (2) Background technology [0002] Asparagus, scientific name Asparagus officinalis, also known as Asparagus officinalis, is a perennial herb of the family Liliaceae Asparagus, and its edible part is its fat and tender young stems. Asparagus is rich in nutrition and has important health care functions. It is one of the main export vegetable varieties in my country. In recent years, with the improvement of our people's living standards and the strengthening of the concept of healthy eating, the domestic consumption of asparagus has also increased rapidly. However, the freshness period of asparagus is short after harvest, which affects the supply and circulation in domestic and foreign markets. At present, there is an urgent need for fresh-keeping methods for green asp...
