通过酶法水解提高薏米粉的溶解性.应用木瓜蛋白酶、胰蛋白酶和风味蛋白酶对薏米蛋白进行水解,测定水解度,结果表明:按木瓜蛋白酶50%,风味蛋白酶50%的比例,最适加酶量为4.0%([E]/[S]),采用双酶水解薏米粉,其固形物溶解度指数(DSI)提高了32.5%,但当相对湿度大于43.16%时,水解薏米粉的吸湿性也增强.根据薏米粉在25℃,相对湿度范围32.78%～97.30%的吸湿量及等温吸湿曲线,Henderson方程能较好的拟合试验结果.

To improve the solubility of adlay powder, the hydrolysis degree of protein in adlay powder by papa-in, trypsin and flavorzyme were investigated. Results : At enzyme proportion of papain 50% and flavorzyme 50%, the optimum enzyme dose is 0.4% ([E]/[S]). The dried matter solubility index (DSI) of adlay powder hydrolyzed with the double enzymatic hydrolysis increases by 32.5% compared with the control sample, but the moisture absorp-tion of the hydrolyzed adlay power increases in relative humidity (RH) above 43.16%. Based on the equilibrium moisture contents for absorption of adlay power determined at 25℃ and RH range of 32.78%～97.30% and the moisture absorption isothermal curves, Henderson equation fits experimental results well.
