Embodiment 1
[0028] A) To prepare ethylene absorbent, first soak zeolite with a particle diameter of 2mm-6mm in saturated potassium permanganate solution for 360min, then filter and dry, and weigh each bag with a weight of 0.9g Amount is sub-packed in waterproof air-permeable paper bag, obtains bagged ethylene absorbent, stand-by, the waterproof air-permeable paper bag described in this step can be purchased by commercially available channels, for example selects for use by Guangming Food Packaging Material Co., Ltd., Changshu City, Jiangsu Province, China. The brand produced and sold in the market before this application was filed was CSG-A type waterproof breathable bag;
[0029] B) Harvesting, picking fresh figs with reddish-purple stripes and / or deep purple-red stripes on the surface without pest erosion, rot, and no skin damage (broken) to obtain fresh figs;
[0030] C) Pre-cooling storage. Put the fresh figs obtained in step B) into a clean open container and send them to a sterilize...
Embodiment 2
[0037] Only change the soaking time in step A) to 240min; change the storage temperature of the cold storage in step C) to -0.5°C, and change the storage time to 9h; change the sterilization temperature in step D) to 2°C, ozone Change the concentration to 0.01mg / L, change the relative humidity to RH80%; change the weight ratio of fresh figs purchased online to bagged ethylene absorbent in step E) to 1000:7.2, and the rest are the same as the description of Example 1.
[0038] By simulating the normal temperature logistics conditions of online shopping for figs, comparative measurement and evaluation show that the method of the present invention is combined with 7.2g ethylene absorbent / (kg fruit) and low-temperature packaging of figs for online shopping positioning heat insulation box, and the good fruit rate is still 100% when the fruit is stored for 14 days. 100%, the good fruit rate is still as high as 90% when stored for 21 days, which is significantly better than that of th...
Embodiment 3
[0040] Only change the soaking time in step A) to 300min; change the fruit picking in step B) to a yellow fresh variety, and the maturity of harvesting is determined to be harvested when the green color of the fruit surface basically fades, and the yellow-white to light yellow color is harvested; The storage temperature of the cold storage in C) is changed to 0°C, and the storage time is changed to 10h; the sterilization temperature in step D) is changed to 4°C, the ozone concentration is changed to 0.05mg / L, and the relative humidity is changed to RH75%; In step E), the weight ratio of fresh figs purchased online to bagged ethylene absorbent was changed to 1000:1.8, and the rest were the same as the description of Example 1.
[0041] By simulating the normal temperature logistics conditions of online shopping for figs, the comparative measurement and evaluation show that the good fruit rate of the control group with ordinary corrugated carton ice packs combined with plastic wr...
