1. Put soybeans (all granular grains are acceptable) into a clean and dry beverage bottle. When you play it for the first time, be sure to pack as many as possible. Tighten the lid and put it in the shade. You can open the lid and eat it in three to five days. Just tighten the cover in time after each use.

2. The advantage of doing this is that the beans don't need any treatment and keep their original flavor.

The principle is that the grain fills the space of the bottle. Without air and oxygen, insects and eggs have no living environment and die. After eating some grain, the insects outside can't get in, and the eggs inside can't be revived, thus achieving the purpose of long-term storage.

If the refrigerator is big enough, you can seal the beans in plastic bags and then put them in the refrigerator for freezing.

Next time you eat, just put it in the pot and cook it.

6. Frozen beans can be cooked quickly without soaking.

7. Insects can't survive in the extremely low temperature in the refrigerator.

8. Clean and sanitary, saving time and effort.
