摘　　要：Fresh blood of Tibetan sheep was subjected to protein separation and spray drying, and the effects of drying process on water content, yield and nitrogen soluble index of plasma powder from blood of Tibetan sheep were investigated. The results showed that the optimum separation parameters were a centrifugal speed at 6 000 r/min, centrifugal time of 20 min, a mass fraction of dry matter of 20%, an inlet air temperature at 180 ℃ and a feed rate at 400 ml/h, under which the plasma protein was a pale yellow powdery solid, indicating a good separation effect.为了开发利用高原藏羊血资源,试验将藏羊血浆进行蛋白分离、喷雾干燥,测定血浆蛋白干燥工艺对藏羊血浆蛋白粉含水量、出粉率、氮溶解指数等参数的影响。结果表明:最佳分离参数是离心转速为6 000 r/min,离心时间为20 min,干物质质量分数为20%,进风温度为180℃,进料速度为400 ml/h,此时血浆蛋白粉呈淡黄色粉末状固体,分离效果较好。
