| 摘 要： | 以北太平洋鱿鱼加工废弃的边角料为原料,采用双螺杆挤压技术,利用响应面分析方法研究了主要操作参数物料含水量、机筒温度和螺杆转速对鱿鱼蛋白挤出物的水分含量和堆积密度的影响,分别建立挤出物水分含量、堆积密度与操作参数的回归拟合方程。结果表明,物料含水量对挤出物水分含量的影响非常明显,两者呈现正相关关系,物料含水量和机筒温度的交互作用对挤出物的水分含量和堆积密度的影响均呈显著性;水分含量、堆积密度与操作参数的回归拟合方程的相关系数R2分别是0.952和0.819,拟合的统计模型具有较高的可信度。

| Abstract: | The waste scrap from the North Pacific squid processing was used as raw material.Effect of extrusion process parameters on the physical properties of extruded squid protein using a twin screw extruder was studied employing response surface methodology.Twin extrusion cooking running parameters,feed moisture,barrel temperature and screw speed were examined as input variables.Meanwhile,as output variables,physical properties of the resultant extrudates included moisture and bulk density.Results showed that moi... |
