Walnut skin is generally difficult to remove. If you use your hands directly, you will blacken your hands and look unsightly. Specifically, you can use the following tips to delete it:

Tip 1: Fold and peel.

Retting and peeling is to pile the harvested walnuts into a pile with a thickness of about 50cm, or cover them with a layer of hay or dried bark. Generally, retting takes 3-5 days. When the peeling or cracking of green husk exceeds 50%, it can be peeled with a stick.

Trick 2: peel the medicine.

Chemical peeling is to soak the harvested green walnuts in 0.3%-0.5% ethephon solution for about half a minute, and then pile them in the shade or indoors with a thickness of about 50cm. When the temperature is 30℃ and the relative humidity is 80%-95%, the peeling rate can reach more than 95% after about 5 days. Peel in about 2 days.

Trick 3: Use a professional peeler.

Now there are machines selling walnut skins on the market, just like peeling potatoes. Throw the walnuts into the machine and remove the green peel.

Coup 4: Dry and peel in the shade.

Peeling in the shade means putting the harvested walnuts in a cool and ventilated place for several days. When the skin is wrinkled and dry, it means that you can peel them off. At this time, the green peels can be removed one by one. Be careful not to dry in the shade for too long, otherwise the walnuts inside will turn black and affect sales.

Tip 5: Remove it manually.

Manual removal is to cut several holes in the picked walnuts with a knife and then gently break them along the crossing. It should be noted that when peeling, you should wear a pair of gloves with glue to avoid blackening your hands. When peeling, don't let the juice touch your eyes, hands and other skin, because the juice is poisonous.
