Dried tofu and sliced tofu are semi-dehydrated bean products, and their water content is significantly lower than that of tofu. Dried bean curd is made by squeezing, dewatering and cutting, also called dried white bean curd. When purchasing, it is better to have white color, uniform thickness, neat corners, softness and strength, and no impurities and odor. Tofu slices are made by squeezing and dewatering. They are also called dried tofu, hundred pages or thousand sheets. The thickness of tofu slices varies from 0.5 mm to 2 mm, which varies with different products. The requirements for selection are the same as those for dried tofu.
