The present invention relates to an improved process for the production of beta-lactoglobulin (BLG) compositions by BLG crystallization. The present invention uses at least two different BLG-containing protein feeds, which are mixed to produce a supersaturated protein solution in which BLG crystallizes. The pH of one of the protein feeds must be at least 5.6, and the pH of one of the protein feeds must be at most 5.4. 本发明涉及一种通过BLG结晶生产β-乳球蛋白(BLG)组合物的改进方法。本发明使用至少两种不同的含BLG的蛋白进料，将所述至少两种不同的含BLG的蛋白进料混合以制备过饱和蛋白溶液，BLG在所述过饱和蛋白溶液中结晶。所述蛋白进料中的一种蛋白进料的pH必须为至少5.6，并且所述蛋白进料中的一种蛋白进料的pH必须为至多5.4。
