中文摘要: 采用双螺杆挤压工艺处理制得营养谷物粉。在单因素试验基础上，采用响应面分析法研究挤压工艺条件对 谷物粉理化特性的影响，分析其主要理化特性。结果表明：螺杆转速为 154.22 r/min，添加水分为 18.72 %，挤压温度为 134.89 ℃、喂料速度 12 kg/h 条件最佳，其吸水性指数（WAI）为 354.059 %。谷物粉经挤压后可溶性膳食纤维（SDF）和 糊化度分别提高 83.96 %、349.33 %；淀粉、蛋白质分别降低 19.30 %、13.78 %。
Abstract:The nutritive cereal flour was prepared by twin-screw extrusion process. Based on the single factor test， the influence of extrusion process conditions on the physical and chemical properties of corn flour was studied by response surface analysis. The main physical and chemical properties were analyzed. The results showed that the screw speed was 154.22 r/min， the moisture content was 18.72 %，the extrusion temperature was 134.89 ℃，the feed rate was 12 kg/h，the water absorption index（WAI） was 354.059 %. Grain powder after extrusion of soluble dietary fiber （SDF） and gelatinization degree were increased by 83.96 % ， 349.33 % ； starch、 protein were decreased by 19.30 %， 13.78 %.
