摘要
采用碱提酸沉法提取膨化的玉米黄粉谷蛋白,选择碱液浓度、温度、料液比和浸提时间作为因素进行试验。确定最佳提取条件:碱液浓度0.55%(m/V),浸提时间100min,温度65℃,料液比1∶16(m∶V)。该条件下玉米谷蛋白的提取率为50.14%。
The method of alkali-dissolution and acid-precipitation of protein were used to extract gluten from extruded corn gluten meal.The concentration of sodium hydroxide,extracting temperature,the ratio of extruded corn gluten meal to solution of sodium hydroxide,and extracting time were investigated with test of single factor and orthogonal design of L16（45）.Optimized extraction condition were,concentration of sodium hydroxide of 0.55%（m/V）,extracting time of 100 min,temperature of 65 ℃ and,ratio of solid-liquid of 1∶16.Under the optimized condition,the yield of gluten was 50.12%.
