| 摘 要： | 以青稞粉为原料,采用双螺杆挤压改性方法加工速食营养粉,研究挤压温度、螺杆转速和物料水分对物料品质的影响规律,并通过二次旋转正交组合实验（响应面实验）,优化营养粉工艺参数.结果表明,物料水分、螺杆转速和挤压温度对于青稞营养粉产品品质影响显著（P＜0.05）.响应面试验得出速食营养粉的较优加工条件：螺杆转速290 r/min,温度165℃和水分含量16.5％.在此优化条件获得青稞预糊化粉的各项指标为：膨化度3.14,吸水指数5.92,容重0.53,碘呈色度5.44.

| Abstract: | Using the twin-screw extrusion modification methods to process instant nutrition powder, the technological parameters： extrusion temperature, material moisture content, screw speed on the physico- chemical properties of the product quality characteristics were studied. The results indicated that material moisture content, screw speed, and extrusion temperature significantly affected （P 〈 0.05） the quality of barley nutrition powder product. The response surface experiment showed that the optimum processing conditions of instant nutrition powder were screw speed of 290 r/rain, temperature of 165 ℃, and mois- ture content of 16.5%. The indicators of barley pre-gelatinized flour obtained under the optimal eondi- tions were expanded degrees 3.14, injectivity index 5.92, density 0.53, and IOD 5.44 |
