摘要
采用酶解法从魔芋精粉中提取葡甘露低聚糖水溶液,通过喷雾干燥制备魔芋葡甘露低聚糖粉,采用单因素和正交试验相结合确定最佳工艺。试验结果表明,当变性淀粉添加量为10%、葡甘露低聚糖水溶液固形物浓度为35%、进风温度为180℃、出风温度为80℃时,喷雾干燥效果最好,在此条件下喷雾葡甘露低聚糖的出粉率为86.12%,水分含量为4.57%。
The oligo-glucomannan solution was extracted from Konjak mannan by enzymatic hydrolysis and konjac oligo-glucomannan powder was prepared by spray-drying. Then the best process was determined with using single factor and orthogonal test. The results showed that the best spray-drying effect was obtained at the condition of the modified starch content 10%, the solids concentration of 35% and the inlet air temperature of 180℃, the outlet air temperature of 80℃.Under the optimum conditions for spray-drying of oligo-glucomannan, the flour yield of konjac oligo-glucomannan reached 86.12% and the moisture content was 4.57%.
