【摘要】 以活性保留率、出粉率为指标,对影响卵黄抗体鸡蛋粉喷雾干燥效果的因素进行了考察,并通过正交实验确定了最佳工艺条件为:进料速度500mL/h、蛋液质量浓度20%、进口温度160℃,此条件下出粉率达到16.23%,IgY(卵黄抗体球蛋白)活性保留率达到92.60%;各因素对出粉率的影响依次为:进口温度>蛋液浓度>进料速度。更多还原

【Abstract】 The effect of reaction parameters on spray-drying of yolk immunoglobulin-rich egg powder were conducted to explore by single factor experiments and orthogonal experiment with activity assays of IgY(yolk immunoglobulin) and yield of egg powder as antigens.The optimal spray-drying conditions were obtained as follows:the feed flow rate was 500mL/h,the concentration of egg liquid was 20% and the inlet air temperature was 160℃.Under those conditions,the yield of egg powder was 16.23% and the activity assays of IgY was 92.60%.In addition,the inlet air temperature had the largest impact on the yield of egg powder followed by concentration of egg liquid and feed flow rate.更多还原
