Banana and plantain belong to the family Musaceae, and they are similar in color, fragrance, taste and shape. To distinguish them, we must start with appearance, color and taste. From the appearance, bananas are crescent-shaped, with short stems and 5-6 edges on the peel. Bananas are thin at both ends, thick in the middle, slightly flat on one side and slightly curved on the other, showing a "round cut". Its fruit stalk is very long and its peel has three edges. From the color point of view, bananas are turquoise when immature, yellow when mature, and have brown spots, which are called "plum blossom spots"; The flesh is yellow and white, and the cross section is nearly round. Banana peel is grayish yellow, and there is no "plum blossom spot" after maturity. The pulp is milky white and the cross section is oblate. From the taste point of view, bananas are rich in flavor and sweet in taste. Although the taste of banana is sweet, it tastes sour and its economic value is lower than that of banana.
