the production of yuba mainly goes through the following steps:
1. soaking soybeans: soak clean soybeans or mung beans in clean water, usually for 8-12 hours, so that the beans can fully absorb water and expand.
2. grinding: grind the soaked beans into a paste. you can use a food blender or soymilk machine to grind the beans.
3. filtration: filter the soy milk through a filter cloth or filter sieve to remove solid particles and obtain pure soy milk.
4. boil: pour the soy milk into a large pot and heat it until it boils. generally, you need to stir while boiling to prevent scorching or overflowing.
5. coagulation: after the soy milk boils, add a coagulant such as hydrochloric acid, sulfuric acid or vinegar to allow the soy milk to solidify into blocks to form yuba.
6. slicing: the solidified beans will become soft and cut into desired shapes and sizes at the appropriate time.
7. drying: spread the cut bean pieces on the drying rack and let them dry naturally. it usually takes 1-2 days to dry the bean pieces.
8. roasting: the dried beans can be further dried by roasting to improve the shelf life and taste.
the above is the traditional yuba production process, and there may be slight differences in different regions and manufacturers.
as a traditional bean product, yuba has a long history and is widely used in china, and its production process has also been improved and perfected over a long period of time.
