How to Peel Green Walnuts, and How Many Jin Yield One Jin of Dried Walnuts

Green walnuts refer to the drupe of the walnut tree, with a spherical nut, a smooth outer pericarp, a fleshy mesocarp, and a hard, wrinkled inner pericarp. The kernel can be eaten, pressed for oil, or used as medicine. So, how do you peel green walnuts? How many jin of green walnuts does it take to yield one jin of dried walnuts? Let's find out below.

1. How do you peel green walnuts?

1. Use the natural shade-drying peeling method. For healthy walnuts with no pests and intact skins, after picking, the natural shade-drying method will let the skin wrinkle and shrivel, so it can be separated from the walnut shell. But for damaged walnuts whose green skin has already partly turned black, this method does not apply, because it will cause blackened skin.

2. Use the manual peeling method. This method is commonly used by everyone, that is, first peel off the large pieces of green skin with a small knife, then continue scrubbing the remaining green skin with a wire brush together with clean water, and finally clean it carefully with a fine needle and a toothbrush. During the peeling process, you must wear gloves, otherwise your hands will be stained black. Also be careful not to splash the juice of the green skin onto other skin, because this juice is toxic.

3. Use the artificial ripening method to peel. Evenly spray a 200-fold diluted “ethephon” solution on the green skin. After one day, the green skin separates from the shell on its own.
