The stone is obovate or oval, sometimes slightly flat, with 4 inconspicuous longitudinal edges.

Carya cathayensis should be uniform in particle size and color, with no broken seeds and deformities.

Step 2 smell it

A good product must be processed from fresh pecans, with rich flavor and refreshing taste; But because the old goods have been stored for too long, the raw seeds of pecans have been dehydrated. After frying, the aroma of walnuts is basically gone, only the ingredients of salt and pepper and cream are mixed with some oil consumption.

3. Listen to the sound

Hold a handful of pecans and put them down one by one at a height of 10 cm. If you hear a sound like a broken table tennis ball, it proves that there is an empty shell.

Step 4 look at nucleolus

Usually, the color of fresh pecan meat is light yellow or amber, and the darker the color, the older the peach pit.

Moreover, dried fruits are prone to mildew if they are not properly preserved. When you buy it, look carefully to see if it is moldy and moth-eaten.
