Green beans are peas or edamame. Green beans are neither peas nor edamame. They are fresh and tender fruits of soybeans, and they become soybeans when they mature. The green pods are rectangular, slightly curved, drooping and yellow-green. This is a very useful way for us to distinguish green beans from peas.
Soybean pods are covered with fine fluff, while green beans are not so much. The pods of green beans are much larger. Most importantly, they eat differently. Soybeans can be eaten with pods, and green beans can only eat beans.
Is mung bean a peeled edamame? It can be roughly understood like this. Both edamame and green beans are produced when soybeans are tender, but edamame is a bean with pods, and green beans are beans after pods are removed. When beans are mature enough, they are dried into soybeans. These three kinds of beans are all the same plant. Soybeans are directly boiled in salt water with pods and can be eaten directly. Peel the green beans and cook them. Soybeans are generally used to make soup.
How to preserve green beans so as not to destroy the long-term preservation of green beans. You must peel the green beans first and blanch them with boiling water, but not for too long. If the blanching time of green beans is too long, cook the green beans, then rinse them with cold water, then put them into a safety bag and put them into the freezer. The first half of the year will not be bad. This is not a long-term preservation. You can peel the green beans first, then put them in a fresh-keeping bag without water, and finally put them in the refrigerator for freezing, so that they can be stored for a week.
