Recovery of lactose from the whey using sonocrystallization was studied experimentally. The effect of sonication medium and irradiation power levels was evaluated using three different ultrasonic equipments. Effects of various parameters such as sonication time, pH of the medium, antisolvent (acetone and acetone-ethanol mixture) and concentration of lactose were determined. The optimal parametric conditions were analyzed using differential scanning calorimetry, thermogravimetric analysis, particle size distribution, and zeta potential measurements. Overall, the highest lactose recovery was obtained using a mixture of acetone and ethanol as antisolvent in bath sonication as well as atomization process.
采用超声结晶法从乳清中回收乳糖。实验研究了超声介质和辐照功率水平的影响，使用了三种不同的超声设备。确定了各种参数的影响，如超声时间、介质 pH 值、抗溶剂（丙酮和丙酮-乙醇混合物）和乳糖浓度。使用差示扫描量热法、热重分析、粒度分布和zeta 电位测量对最佳参数条件进行了分析。总体而言，在浴式超声和雾化过程中，使用丙酮和乙醇混合物作为抗溶剂可获得最高的乳糖回收率。
