More Information
Summary:The invention discloses protein nanoparticles and a preparation method thereof. The preparation method comprises the following steps: mixing protein with water 20-200 times the weight of the protein; adding glutaminase accounting for 0.01-1% of the protein weight; adjusting the pH; preserving heat for 0.5-24h at 20-55 DEG C; preserving heat for 5-30min at 70-95 DEG C and deactivating enzyme; centrifuging; and fetching the supernate to obtain the protein nanoparticles. Without adding any food additive, the method for preparing protein nanoparticles disclosed by the invention has the advantages of simple preparation technology, mild reaction conditions, low equipment requirements and the like. 本发明公开了种蛋白质纳米颗粒及其制备方法。该制备方法步骤为：蛋白质与20-200倍重量的水混合后，添加蛋白质重量0.01-1%的谷氨酰胺酶，调节pH，20-55℃保温0.5-24h后，70-95℃保温5-30min灭酶，离心，取上清液，得蛋白质纳米颗粒。本发明公开的制备蛋白质纳米颗粒的方法无需添加任何食品添加剂，具有制备工艺简单、反应条件温和、设备要求低等优点。
