常规的植物蛋白生产方法涉及使用溶剂、浓酸和碱，其可导致蛋白质变性和溶解度损失，从而降低蛋白质成分的质量和功能性。以菜豆粉为模型体系，研究了一种新型的无溶剂摩擦静电分离法生产高品质植物蛋白粉。该工艺由流化床面粉储存器、摩擦充电单元和分离装置组成。使用这种方法，在从分离器中的板的底部收集的最终富含蛋白质的级分中，原始海军豆粉的蛋白质含量从25.4%增加到47.0%。测试了各种不同尺寸、形状和材料的摩擦充电管，以评估其效率。通过这种方法的蛋白质回收率高于其他无溶剂分离方法，并可以通过进一步优化流速和分离器的设计配置来提高。
Conventional plant protein production methods involve the use of solvents, concentrated acids and alkali that can result in protein denaturation and loss of solubility, thereby reducing the quality and functionality of protein ingredients. A novel solvent-free tribo-electrostatic separation approach was developed for the production of high quality plant protein powders using navy bean flour as a model system. The process consisted of a fluidized bed flour reservoir, tribo-charging unit, and a separating device. Using this approach the protein content of the original navy bean flour was increased from 25.4% to 47.0% in the final protein-enriched fraction collected from the bottom section of the plate in the separator. A wide variety of tribo-charging tubes with different sizes, shapes, and materials were tested to evaluate their efficiency. Protein recovery by this approach was higher than other solvent-free separation approaches and could be improved by further optimization of the flow rate and design configuration of the separator.
