摘要 采用动态超高压均质技术制备纳米级蛋白,并研究了纳米级蛋白的功能性质。结果表明,大豆分离蛋白溶液经过60、80、100、140MPa超高压均质后,18%的颗粒≤100nm,属于纳米级蛋白。纳米级蛋白的溶解性、起泡性、凝胶性、流变性都有不同程度的改善:大豆分离蛋白溶解度可以达到46.33g/L;100mL的大豆分离蛋白经高速分散搅打后,泡沫高度可以达到180mL;16%大豆分离蛋白凝胶强度可以达到0.08355kg;流体呈现出接近于牛顿流体的性质。 High-pressure microfluidization was introduced to prepare nanoprotein, and functional properties of which were studied. As a result, after 60,80,100, 140MPa microfluidization, 18% soy protein isolate≤ 100nm, which belonged to nanoprotein. Nanoprotein's solubility, foaming, gelation, viscosity were improved: solubility could reach 46.33g/L; the foam height of 100mL 6% soy protein isolate could reach 180mL after blending; the gel intensity of 16% soy protein isolation could reach 0.08355kg, solution was similar to Newtonian fluids.
