It not only can improve the appearance and health, but also has the effect of strengthening the stomach and kidneys. Whenever cowpeas are harvested, how to deal with them becomes a big problem. Below is the method of quick freezing cowpea compiled by the editor.

Process flow

Raw material acceptance → selection → cross-section cutting → selection → salt water soaking → rinsing → blanching → cooling → drainage → quick freezing → packaging → frozen storage.

Operation points

1. Choose cowpea varieties with dark color and uniform size. The bean body has no obvious protrusions, the tissue is fresh and tender, and the color is green or light green; green and light green should not be mixed. The strips are round and straight, the cross-section diameter of the beans is about 0.5cm, there are no pests, diseases, scars, or miscellaneous beans.

Let’s continue to introduce the topic of this issue in depth.

2. After cutting off both ends of the beans, select the segments, remove the variegated beans, heterochromatic beans and impurities, and pay attention to the wormholes. Then cut into 5 cm long segments or dice.

5. Pretreated beans should be frozen as soon as possible. They can be pre-cooled to 0-5℃, then sent to the quick freezing room for quick freezing at -35℃.

6. Packing is in 250g or 500g plastic bags and then packed in 10kg cartons. /7. Stable temperature and humidity should be maintained during refrigeration.
