Problems solved by technology

But its disadvantages are: stack retting and peeling method: serious rot; long time, generally takes about 7 days; serious pollution of the core, the surface of the walnut after peeling is slightly black, some walnuts have local pollution on the surface, and some even have kernels Deterioration occurred, which seriously affected the product quality of walnuts
The standard of freezing is that all the green peels are frozen, and there are obvious ice chips embedded in the green peels when peeling off, and the low temperature environment increases the cost of machine investment and increases the burden on farmers; the green peeling time is also longer

Abstract

The present invention provides a method for removing walnut green seedcases. The method comprises the following steps: (1) picked fresh walnuts are selected and diseased and rotten fruits are removed;(2) the selected fresh walnuts are soaked in a mixed solution I, the mixed solution I comprises the following raw materials in parts by weight: 2-4 parts of sodium dihydrogen citrate, 5-10 parts of sodium citrate and 60-80 parts of an ethephon solution, and concentration of the ethephon solution is 1,000-2,000 ppm; (3) the soaked fresh walnuts are taken out to be shaken together with steel ballsfor peeling to produce the walnuts; (4) the produced walnuts are soaked in a preservation color protectant solution; and (5) washing, sun-drying and packaging are conducted. The method can rapidly peel the green seedcases, only needs 8-35 min, also has a fruit yield as high as 95.1%-98.6%, is simple and convenient, does not require low-temperature refrigerators or ice cubes, etc.

Description

technical field [0001] The invention relates to the technical field of peeling green walnuts, in particular to a method for peeling green walnuts. Background technique [0002] Walnuts are rich in nutrients and have the functions of nourishing the kidneys, nourishing the lungs, moistening the intestines, strengthening the body and brain, and rejuvenating the skin and prolonging life. The green walnut peel is rich in vitamin B and vitamin C, which is equivalent to 40-50 times the content of orange pincers. It also contains quercetin, kaempferol and other substances, which can be used in traditional Chinese medicine to treat some skin diseases and gastric neuralgia ; Green fruit peel can also be used as a pesticide. But the green walnut peel is solid waste again for merchants. According to measurements, the moisture content of the walnut green skin just after harvesting is 40% to 50%. Such a high moisture content can easily cause walnuts to rot and deteriorate after harvesti...
