Embodiment 1

[0017] 1. The effect of microwave irradiation treatment on the storage and preservation of Xuan papaya:

[0018] Select 150 kg of 8 mature harvested Xuan papayas, divide them into 15 groups, each group is 10 kg, irradiate Xuan papaya with output power of 35W, 65W, 95W, 125W, and 155W for 2min, 3min, and 4min with a microwave generator, and then in 2~ 4°C, refrigerated and kept fresh for 180 days and 200 days at a relative humidity of 90 to 92%, and measured the temperature, rot rate and good fruit rate of the fruit. The results are shown in Table 1 below. Occupation rate of Xuan papaya whose ingredients and quality characteristics meet the quality requirements of raw materials for processing and production:

[0021] It can be seen from Table 1 that with the increase of power and time extension of microwave treatment, the temperature of the irradiated ...

Embodiment 2

[0042] A kind of storage and fresh-keeping method of Xuan papaya provided by the present embodiment comprises the following steps:

[0043] Step 1: Select 300 kg of 8 mature harvested Xuan papaya fruits, and irradiate Xuan papaya with 65W output power for 3 minutes with a microwave generator;

[0044] Step 2: In a closed environment, fumigate the Xuan papaya after microwave irradiation with 1-methylcyclopropene (1-MCP) (0.75ul / L), and control the ambient temperature and fumigation time according to Table 5 during the fumigation process;

[0045] Step 3: Refrigerate and keep fresh for 200 days at 2-4°C and relative humidity 90-92%. At the same time, regularly treat the refrigerator with ozone, and the concentration of ozone treatment is 10-15mg / m 3 , the treatment time is to process once every 5 days, each time for 1 hour, and observe the fresh-keeping effect. The specific results are shown in Table 5 below:

Abstract

The invention discloses a storing and fresh-keeping method of chaenomeles speciosa. The method includes following steps: performing microwave irradiation with an output power being 65W for 3 min to the chaenomeles speciosa; smoking the chaenomeles speciosa with 1-methylcyclopropylene; and finally performing refrigerating fresh-keeping at 2-4 DEG C under relative moisture of 90-92%. By means of the method, effective control in storage physiology, storage biochemistry and storage quality of the chaenomeles speciosa is all achieved and a senility process is alleviated. A fresh-keeping time can be prolonged to more than 200 days. The method is simple and easy to carry out, is scientific and reasonable, is green and safe, is convenient to popularize and can achieve a long-period storage object of the chaenomeles speciosa.

Description

technical field [0001] The invention relates to a fresh-keeping method for fruits, in particular to a storage and fresh-keeping method for Xuan papaya. Background technique [0002] Xuan papaya is the fruit of Rosaceae, Apple subfamily, Papaya genus, deciduous shrub Begonia, and is a famous specialty in Anhui. Xuan papaya is popular because it has the effects of calming the liver and stomach, expelling wind and dampness, and has significant health functions. Since the artificial planting began in the 1970s, the cultivation area has doubled. According to relevant literature reports, papaya fruit is rich in oleanolic acid, malic acid, tartaric acid, citric acid, saponins and flavonoids, contains 19 kinds of amino acids and 18 kinds of mineral trace elements necessary for human body, especially contains anti-aging super Oxide dismutase (SOD) and protease, the fruit is hard and sour, not suitable for direct fresh eating, but the processing quality is good, and it has dual funct...
