Abstract
Disclosed is a method for purifying pea albumin PA1a by using a negatively charged polysaccharide, which belongs to the field of protein extraction technology. According to the invention, with a natural edible negatively charged polysaccharide as a recycling material, based on the technical principle that the negatively charged polysaccharide preferentially binds to non-target proteins to precipitate and undergoes phase separation relative to the target protein, the separation and purification of pea albumin PA1a are realized to prepare pure PA1a. From the perspective of resource recycling, the invention can realize high value-added utilization of byproducts of pea protein isolate processing and prepare high-purity high-sulfur active protein components therefrom, thereby providing technical support for subsequent research. The invention features improved comprehensive utilization of pea whey, high recycle rate of PA1a protein with high purity, low requirements on equipment, simple and rapid operation and no environmental pollution.
