中文摘要: 以徐香猕猴桃为原料制取猕猴桃粉,采用双螺杆挤压联合气流式超微粉碎法对其进行改性处理。结果表明,双螺杆挤压条件为物料过筛目数80目、加水量30%、螺杆转速700 r/min;超微粉碎处理条件为粉碎频率30 Hz、研磨压力0.8 MPa、粉碎时间20 min。经螺杆挤压-超微粉碎联合改性后,猕猴桃粉颗粒中位粒径从165.05 μm降至15.86 μm,可溶性膳食纤维含量从6.27%增至19.06%,其持水力、膨胀力和分散性均得到改善(P<0.05)。
Abstract:Kiwifruit powder was prepared from Xuxiang kiwifruit and modified by twin-screw extrusion combined with airflow superfine comminution.The results showed that the extruding conditions of twin-screw extrusion were 80 sieving mesh of the material,30%amount water addition,and 700 r/min screw speed.The superfine comminution conditions were 30 Hz grinding frequency,0.8 MPa grinding pressure,and grinding for 20 min.After the combined modification,the medium particle size of kiwifruit powder decreased from 165.05 μm to 15.86 μm,the content of soluble dietary fiber increased from 6.27%to 19.06% ,and the water holding capacity,expansion capacity,and dispersibility were significantly improved(P<0.05).
