响应面优化灵芝孢子粉挤出破壁工艺

Response Surface Optimization of Ganoderma lucidum Spore Powder Extrusion Process

采用双螺杆挤出技术对灵芝孢子粉进行破壁处理,利用响应面对影响挤出破壁工艺的主要因素:挤出温度、螺杆转速、物料含水量进行优化。结果表明:当挤出温度110℃、物料含水量27%、螺杆转速640 r/min时,灵芝孢子粉破壁率可达到96.48%。方差分析结果表明,影响挤出破壁灵芝孢子粉工艺的因素由强到弱依次为挤出温度>物料含水量>螺杆转速。

The twin-screw extrusion technique was used to break down the Ganoderma lucidum spore powder,and the main factors influencing the extrusion process was as follows:the extrusion temperature,the screw speed and the material water content was optimized. The results showed that the breaking rate of Ganoderma lucidum spore powder reached 96.48 % when the extrusion temperature was 110 ℃,the water content was 27 %and the screw speed was 640 r/min. The results of variance analysis showed that the factors affecting the process of spore powder from Ganoderma lucidum was extruded from strong to weak,> water content> screw speed.
