Walnut is a kind of dried fruit that we are very familiar with. Walnut is rich in protein, fat, carbohydrates and various trace elements. Eating walnuts regularly is very helpful to our brain development and physical health. Eating walnuts regularly also has the effects of beauty and anti-aging.

Can walnuts with white fluff be eaten?

When eating, you need to peel and remove the mold.

Walnuts are knocked off before they are naturally ripe. A small amount of residual liquid inside the kernel that has not yet matured will become moldy due to the influence of external temperature (poor air permeability). The skin must be peeled to remove the mold when eating.

2. Smell walnuts

Many walnuts sold on the market have been bleached with bleaching liquid, which makes them look good, but harms consumers. Because the shells of many walnuts are not completely sealed, soaking them for too long can easily cause bleaching powder water to enter the inside of the walnuts, thus endangering the health of consumers. Therefore, it is necessary to smell the walnuts. If they have a fresh fragrance or no smell, you can buy them. If they have a smell of bleach, mold, sourness or other strange smells, it is best not to buy them.

3. Weigh it in your hand

Take the walnut in your hand and weigh it. If the walnut is relatively heavy, it is most likely a good walnut. Don't just look at the size, consider the weight of the walnut
