black bean milk

Soybeans are rich in high-quality protein, and protein is the main substance that makes up the human body and the material basis of human life activities. Engels pointed out: "The basic feature of life is that the chemical composition of protein often self-updates."

The protein content is as high as about 40%, and black beans can reach 50%, which is more than twice that of lean pork, three times that of eggs, and 12 times that of milk. The composition of amino acids in soybean protein is relatively close to that needed by the human body. It belongs to complete protein. Every 100 grams of soybean contains about 11 mg of iron and 480 mg of phosphorus. It also contains vitamins A, B1, B2, D, E, etc., and is known as "vegetable meat","green dairy cow", and "king of beans". When soybeans are processed into fresh soy milk, their structural state has changed, the degree of protein dissociation has been greatly improved, and the absorption rate has been improved. According to scientific tests, the digestion and absorption rate of fresh soy milk is as high as 95%, which is much higher than boiled soy (65%), whole fat soy milk (80%), and defatted soy milk (85%).
