目的优化沙棘固本速溶茶最佳低温喷雾干燥工艺参数,为工业化生产提供依据.方法采用苯酚-硫酸比色法测定沙棘固本速溶茶干浸膏粉中多糖含量,HPLC测定沙棘固本速溶茶干浸膏粉中人参皂苷Re、Rg1、Rb1的含量,以干浸膏粉质量、多糖含量及人参皂苷Re、Rg1、Rb1含量为评价指标,单因素试验法及响应面设计试验法优化沙棘固本速溶茶低温喷雾干燥工艺参数.结果最优低温喷雾干燥工艺参数如下:药液相对密度1.08 g·mL~(-1),进风温度120 ℃,泵药速度20 RPM,风机速度25 m~3·h~(-1),雾化压强0.4 Mpa.结论沙棘固本速溶茶提取浓缩液适合采用低温喷雾干燥法制备干浸膏粉,低温喷雾干燥系瞬间干燥,速度快,对功能性成...

OBJECTIVE To optimize parameters of low-temperature spray-drying process of Sea-buckthorn Strengthening Tea granules, provide the basis for industrialization. METHODS The polysaccharide content in Sea-buckthorn Strengthening Tea granules was measured by phenol-dense sulphuric acid method. The content of ginsenoside Re, Rg1, Rb1 in Sea-buckthorn Strengthening Tea granules were measured by HPLC. The amount percent of weight, polysaccharide content and the content of ginsenoside Re, Rg1, Rb1 of dry granulation were taken as the indexes of low-temp...
