Yellow black beans without soaking to beat soybean milk is not good, may affect the taste of soybean milk and absorption of nutrients.

Soaked soybeans and black beans to beat soybean milk better reason:

Soybean outer layer is a layer of thick fibers can not be digested and absorbed by the human body, which prevents the soy protein is absorbed by the body, if not sufficiently soaked is difficult to wash thoroughly;

Do soak soybeans before making soybean milk, so that the outer layer of the softened, and then crushed, filtered, and sufficiently heated to improve the nutritional relative to soybeans

These are the first time I've ever seen a woman with a baby in her arms, and I've never seen a woman with a baby in her arms.

So, with dry beans made of soybean milk in the concentration, nutrient absorption rate, taste, flavor, etc. than with soaked beans made of soybean milk. It is best to soak the beans before making soybean milk, which can improve the crushing effect and pulp rate, but also health and hygiene.
