Description

technical field [0001] The invention belongs to the field of soybean protein isolate production, and in particular relates to an ultrasonic-assisted extraction tube bundle device and a method for extracting soybean protein isolate. Background technique [0002] With the improvement of people's living standards, soy protein isolates have become more and more common meals. Soybean Protein Isolate is a full-price protein food additive produced from low-temperature desolvated soybean meal. The protein content of soybean protein isolate is more than 90%, there are nearly 20 kinds of amino acids, and it contains essential amino acids for human body. It is rich in nutrition and does not contain cholesterol. It is one of the few varieties of vegetable protein that can replace animal protein. [0003] The principle of soybean protein production process: Most of the protein in low-temperature defatted soybean meal can be dissolved in dilute alkali solution. After the low-temperatur...
