1, appearance is different: the skin of sweet potatoes is usually red or purple, and the shape is fusiform or round. The skin of white potatoes is light brown or light gray, and more slender, similar to the shape of carrots. The inner flesh of sweet potatoes is orange or dark red, while the inner flesh of white potatoes is white.

2, the texture is different: sweet potatoes are usually more moist and sweet, with a softer texture. White potatoes are relatively dry and starchy, so they have a harder texture, are relatively less sweet and require more cooking time to soften.

3, storage is different: white potatoes and sweet potatoes should be stored in a cool, dry, ventilated place to avoid spoilage. However, sweet potatoes are more susceptible to black spot disease during storage, so special attention needs to be paid to the storage environment and temperature.
