Yuba is made by heating and boiling soy milk, and then keeping it warm for a period of time. A thin film forms on the surface, which is picked out and drooped into a branch shape, and then dried.

Yuba, also known as bean curd skin, is a traditional soybean food of the Han nationality and a common food ingredient in Chinese areas. It has a rich bean flavor and a unique taste that other soybean products do not have. Yuba is yellow-white in color, translucent and rich in protein and various nutrients. It can be soaked in water for 3-5 hours to develop.

It can be eaten as meat or vegetable, grilled, stir-fried, cold, soup, etc. It is fragrant and refreshing, and meat and vegetarian dishes have unique flavors. Good-quality yuba is in the shape of branches or leaves. It is brittle and easy to break. There is a hollow when the strip is broken, and there is no mold, impurities, or insects. Inferior yuba is in the shape of branches or leaves, with more broken branches or fragments and more solid bars.
