The yuba is cooked when it is processed. You can eat it directly after soaking in cold water, but for the sake of hygiene, it is best to blanch it with hot water before eating. The foaming time should not exceed 72 hours. If it exceeds 72 hours, it will completely deteriorate and be completely inedible. Because it takes too long, the colonies in the water will multiply and pollute the ingredients.

Yuba, also known as tofu, is a traditional bean food of Han nationality and a common food raw material in China. It has a strong bean flavor and a unique taste that other soy products do not have. Yuba is yellow and white in color and bright in luster, and is rich in protein and various nutrients.
