Walnuts to remove the green skin

Buried in the soil, waiting for the natural decay of the green skin and then dug out and washed. Now unscrupulous traders are using acid and alkali chemical soaking. Chemical soaking peeled walnut skin color white, look clean, skin easy to break.

The following is more troublesome:

1: natural drying of walnuts, choose healthy, disease-free, no insect pests, skin intact walnuts, down the tree into a ventilated place to natural drying. A few days after the walnut's epidermis appeared wrinkled and dried, the green skin will be naturally separated from the walnut, but pay attention to walnuts with injuries, the green skin will be blackened locally, so do not apply to this method, because it will result in shady skin.

2: artificial walnut green skin: need to prepare tools, rubber gloves, small hammer, knife, iron brush. Tap the walnut green skin with a small hammer or knife first large pieces of green skin off, and then use an iron brush dipped in water to continue to brush the remaining remnants of the green skin, and finally with a fine needle and toothbrush to carefully clean up again. It is best to wear rubber gloves throughout the process, or the skin on your hands will be stained black.

3: artificial ripening. With 200 times liquid "ethylene glycol" solution evenly sprayed on the green skin, a full day later, the green skin will automatically separate.
