AI Technical Summary
Existing pea protein isolate extraction processes struggle to effectively break down the complex interactions between proteins and cell wall polysaccharides, resulting in large fluctuations in protein extraction rates, difficulty in consistently achieving high purity levels, and ineffective modification of byproducts, leading to significant resource waste, inconsistent product performance, and an inability to meet the requirements of high-end applications.
Sodium hexametaphosphate chelating agent is used to shield ion bridging, combined with multi-enzyme stepwise hydrolysis and high-pressure microfluidic induction of interfacial self-assembly between nanocellulose crystals and sodium caseinate, energy field activation and covalent cross-linking of glutamine transaminase are carried out using dielectric barrier discharge plasma, and finally the powder is dried by flash evaporation.
It significantly improves protein extraction rate and purity, enhances product solubility, emulsification, and the solubility and physiological adsorption activity of dietary fiber, ensuring product processing stability and uniformity, and possesses excellent industrial application value.
