Amphiphilic protein microfibrils have been generated for the first time by ice-templated self-assembly of aqueous globular protein colloids and subsequent selective disassembly in polar solvents like MeOH, EtOH, acetone, and dimethylformamide. Semicrystalline microfibrils, ca. 1.2 μm wide and 45–70 μm long, produced from soy proteins are excellent amphiphiles, which are capable of stabilizing both high-internal-phase o/w and w1/o/w2 double emulsions as well as retaining amphiphilicity even with surface-bound lipophiles and electrophiles. This ice-templated self-assembling and polar solvent disassembling approach is applicable to other legume proteins, such as pea proteins, and is scalable to process globular proteins into amphiphilic microfibrils for Pickering emulsions in many potential applications including food, pharmaceuticals and skin care.

来自冰模板自组装和皮克林乳液拆卸的两亲蛋白微纤维
两性蛋白微纤维首次通过水性球状蛋白胶体的冰模板自组装和随后在极性溶剂（如 MeOH、EtOH、丙酮和二甲基甲酰胺）中的选择性分解而产生。半结晶微纤维，约。由大豆蛋白制成的 1.2 μm 宽和 45–70 μm 长是极好的两亲物，能够稳定高内相 o/w 和 w 1 /o/w 2双重乳液以及即使与表面结合的亲油剂和亲电剂保持两亲性。这种以冰为模板的自组装和极性溶剂拆卸方法适用于其他豆类蛋白，例如豌豆蛋白，并且可扩展以将球状蛋白加工成两亲性微纤维，用于在食品、药物和皮肤护理等许多潜在应用中的 Pickering 乳液。
