【摘要】 为了研究莲藕粉糊的流变特性参数 ,以开发莲藕方便食品 ,采用一套同心圆筒旋转粘度仪测绘了不同浓度、粒度、p H值条件下莲藕粉糊的流变特性曲线 ,并对浓度、粒度、p H值和温度对莲藕粉糊流变学行为的影响进行了分析研究。结果表明 ,浓度从 2 %增至 10 %时 ,稠度系数从 0 .4 34增至 2 0 .30 2。建立了表观粘度随浓度的变化规律的回归方程 ,其相关系数高达 0 .9931。更多还原

【Abstract】 Reological behaviors of lotus root powder paste with different concentration, pH values, particle sizes and temperatures were measured by a concentric cylinder viscometer. The effects of concentration, particle sizes, pH values and temperatures on the reological behaviors were studied. The results indicated that the consistency index increased sharply from 0.434 to 20.302 when the concentration increased from 2% to 10%. The relationship between apparent viscosity (η a) and concentration could be demonstrated by a regression equation (η a=0.2287C 2.5138 , R=0.9931).更多还原
