How to store frozen green beans without spoiling

There are several ways to preserve frozen green beans without spoiling:

‌Direct freezing method‌: After peeling the fresh green beans, put them directly into a fresh-keeping bag, remove the air, seal it, and then put it in the freezer. This method is simple and convenient, but the storage time is longer (about half a year), and it may take a little longer to cook after thawing.

‌Blanching and freezing method‌: First, blanch the green beans in boiling water (about 2-4 minutes), then rinse with cold water and drain the water, and finally put them in a fresh-keeping bag or freezer box and put them in the freezer. This method can keep the green beans fresh and tender, and cook faster.

‌Nitrogen preservation method‌: After blanching the green beans, dry them, put them in a fresh-keeping bag, and remove the air. If conditions permit, nitrogen can be introduced to isolate oxygen. This method has a very good preservation effect; the green beans are bright in color and taste better, but professional equipment is required.

‌Freeze after blanching‌: Blanch the green beans in boiling water (adjust the time according to the size of the green beans), then quickly cool them in ice water, drain them, and finally freeze them in a sealed bag. This method can better maintain the freshness and taste of the green beans‌.

‌Packaging and storage‌: Whether freezing directly or blanching and freezing, the green beans can be packaged into small packages, and the date and quantity can be written on each package, which is convenient for access and management‌.
