摘要
采用双螺杆挤压机将9种谷物在同一条件下挤压膨化,研究比较了9种谷物原料挤压后的理化性质:糊化度、吸水指数、水溶性指数、膨胀度、硬度、脆性和保脆性,分析了谷物原料成分与挤压后产品的理化性质之间的相关关系,以及各理化性质之间的相关关系。
Extrusion cooking has become an important direction of grain processing.Nine kinds of grain were extruded using a twin-screw extruder in the same condition.The physicochemical properties of extruded products,which inlcuded gelatinization degree,water absorption index,water solubility index,expansion ratio,hardness,crispness and bowl life,were studied and comparied.The correlation between the composition of materials and physicochemical properties of products,as well as the correlation between the physical and chemical properties,were studied.
