Embodiment 1

[0015] (1) Fresh-keeping effects of different treatments on celery under refrigeration

[0016] Taking celery as an example, select samples with consistent freshness and maturity, no disease and mechanical damage, and divide them into two groups: the first group is treated by the present invention, and the second group is a blank control without any treatment. The two groups of samples were put into storage at the same time, and stored in a mechanical cold storage at 1±0.5°C and a relative humidity of 90% for 15 days. The fresh-keeping effects of each group of treatments are shown in Table 1.

[0024] Taking coriander as an example, select samples with consistent freshness and maturity, no disease and mechanical damage, and divide them into two groups. The first group is processed by the present invention, and the second group is a blank control without any treatment. The two groups of samples were put into storage at the same time, and stored in a mechanical cold storage at 2±0.5° C. and a relative humidity of 90% for 12 days. Table 3 shows the fresh-keeping effects of each group of treatments.

[0028] Taking leek as an example, select samples with consistent freshness and maturity, no disease and mechanical damage, and divide them into two groups. The first group is processed by the present invention, and the second group is a blank control without any treatment. The two groups of samples were put into storage at the same time, and stored in a mechanical cold storage at 5±0.5° C. and a relative humidity of 90% for 7 days. The fresh-keeping effects of each group of treatments are shown in Table 4.

Abstract

The invention provides a green vegetable compound antistaling agent and a matched antistaling method thereof. The method is characterized by comprising the following steps of: (1) selecting fresh and complete green vegetables without disease, removing impurities, and washing with running water; (2) immersing the drained vegetables in the green vegetable compound antistaling agent compounded by sodium erythorbate, kojic acid, gibberellin, salicylic acid and magnesium sulfate for 15 minutes, and drying by using cold air; and (3) packaging the vegetables in a freshness protection package specialfor green vegetables with air-regulating and humidity-breathing function, fastening the package mouth, putting into a packing box and storing at proper temperature, wherein the vegetables in each package do not exceed 2kg and the weight is consistent. The green vegetable compound antistaling agent can make the green vegetables stored at low temperature for 10 to 15 days or keep the color, freshness and mouthfeel of the vegetables in normal-temperature shelf life of 3 to 6 days, and is safe and nontoxic; and the method is simple and has promotion and application value.

Description

[0001] The invention belongs to the field of food preservation, and in particular relates to a compound antistaling agent Luyexian which can be used for green leafy vegetables and a matching freshness preservation method thereof, in particular to a formula of the compound antistaling agent and a matching method for storage and preservation. Background technique [0002] Vegetables have unique advantages and status in my country's agricultural development. In recent years, my country's vegetable industry has developed very rapidly. In many areas, vegetables have become an important growth point to promote the adjustment of agricultural industries and increase farmers' income. But at present, the postharvest treatment technology of vegetables in our country is backward, and the postharvest loss rate is 25% to 30%, and the postharvest loss rate of green leafy vegetables is even as high as more than 50%. Every year, the quality deterioration of post-harvest vegetables causes a larg...
