How to Choose Walnuts for Eating

1. Look at the shell

A good walnut has a round and neat appearance, a thin and clean outer shell, uniform patterns, and tight stitching. The darker the color of the walnut shell, the longer it ages. If there are oil stains seeping out of the walnut shell, it indicates that the walnut has deteriorated. In addition, check if there is any damage to the outer shell. If the outer shell is damaged, the nuts inside will be contaminated and therefore cannot be consumed.

2. Weigh

Take a walnut and weigh it in your hand. The lighter the walnut, the less and shriveled the kernels, and it may be empty or bad; On the contrary, it indicates that the nucleolus is very plump.

3. Look at the nucleolus

The color of walnut kernel coat should be slightly white in yellow, and dark yellow or brown yellow is also acceptable. If the color of the walnut kernel coat is black brown, it cannot be eaten. If it is too white, it indicates that it has been smoked with sulfur and is not suitable for consumption. The color of walnut meat is light yellow or light amber, and the darker the color, the longer the peach stones are stored.

4. Shake the fruit shell

The kernels in a good walnut are still intact after shaking. If you feel the flesh inside the walnut shaking, it is likely to be of inferior quality and it is not recommended to purchase.

5. Listening to sound

Holding and rubbing the advantageous walnut in your hand will give you a sound of gold and stone, which is very solid and tough. This type of walnut is generally wild. If Pila Pila's empty voice, it is mostly grafted walnuts, and they were picked earlier. You can also throw walnuts on the hard ground from about a foot high to listen to the sound. Empty fruits will make a sound similar to a broken ping pong ball, while the sound of real fruits is relatively dull.

What to pay attention to when choosing walnuts

1. Pay attention to the veins

A good walnut has relatively more lines and is not deep, because the nutrients absorbed by the walnut during its growth process are transported by the lines. The more lines there are, the more nutrients the walnut contains. The shell of low-quality walnuts is very smooth, with almost no visible lines.

2. Pay attention to the taste

We can determine whether walnuts are fresh and edible by smelling them. A good walnut should have no peculiar smell, and a walnut that can smell a peculiar smell indicates that it has soured and spoiled, and cannot be consumed. In addition, special attention should be paid to whether walnuts have a slight chemical irritating taste, as some unscrupulous vendors may soak walnuts in chemicals such as hydrogen peroxide to make their appearance smooth and beautiful. Once consumed, it can affect people's health.
