Walnut skin is generally difficult to remove. If you use your hands directly, your hands will become black and look unsightly. Specifically, you can use the following tips to remove it:
Tip 1: Pile and peel.
Retting and peeling is to pile the harvested walnuts into a pile with a thickness of about 50cm, or cover it with a layer of hay or dry bark. Generally retting takes 3-5 days. When the green skin peels or cracks more than 50%, you can use a stick to peel it.
Trick two: peel off the medicine.
Chemical peeling involves soaking the harvested green walnuts in a 0.3-0.5 ethephon solution for about half a minute, and then stacking them in a cool place or indoors with a thickness of about 50cm. At a temperature of 30°C and a relative humidity of 80-95, the peeling rate can reach over 95 after about 5 days. Peel them in about 2 days.
Trick three: Use a professional peeling machine.
There are walnut peeling machines on the market now, which have the same properties as peeling potatoes. Throw the walnuts into the machine and remove the green peel.
Tip 4: Dry and peel.
Peeling in a cool place means placing the harvested walnuts in a cool and ventilated place for a few days. When the skin is wrinkled and dry, it means you can peel them. At this time, you can remove the green skin one by one. Be careful not to dry it in a cool place for too long, otherwise the walnuts inside will turn black and affect sales.
Tip 5: Manual removal
Manual removal is to use a knife to cut a few holes in the picked walnuts, and then gently open them along the entrance. It should be noted that when peeling, you should wear a pair of rubber gloves to prevent your hands from turning black. When peeling, do not get the juice on your eyes, hands and other skin, because the juice is poisonous.
