Soybean and soybean are actually the same thing, but in different states. One is fresh and the other is dry. Soybean was planted in May (Northeast China), and around August, pods were formed and the beans inside were full. At this time, when the water content of beans is the highest, the beans collected from the ground are still green. We call this kind of bean edamame. Later, the beans gradually lost moisture, and the pods became crisp, and some even burst. The beans in it are the soybeans that we often see used to make tofu, soybean milk and oil.

It is also true that soybeans are old edamame. The correct statement should be that soybeans have completed physiological post-ripening, and edamame was picked when it was green.

Compared with the nutrient composition table of soybean, the nutritional value of soybean is higher. Because edamame is a fresh vegetable, it contains many vitamins, carotene and so on.
