摘要
为了充分利用大球盖菇漂烫液的营养成分,对其进行喷雾干燥,并优化其工艺参数,选取热风温度、雾化压力和总固形物质量分数3个因素进行响应面法组合设计,对大球盖菇漂烫液喷雾干燥工艺参数进行优化。结果显示:大球盖菇漂烫液喷雾干燥的较佳工艺条件为β-环糊精添加量15%、进料流量10mL/min、进料温度70℃、热风温度172℃、雾化压力92MPa、总固形物质量分数15%,该条件下大球盖菇漂烫液营养精粉得率为60.26%、抗氧化保留率83.92%、含水率3.2%、溶解时间65s。研究为实现大球盖菇漂烫液的资源化利用提供参考。
In order to make an effective use of blanching liquid nutrients, the technology of spray drying for Stropharia rugoso-annulata Farlow was studied. With response surface analytic method, the hot air temperature, atomization pressure and total solid content were investigated in central composite design to optimize spray drying parameters. Results showed that the maximized drying efficiency obtained with processing parameters of hot air temperature 172 ℃, atomization pressure 92MPa and total solid content 15%, respectively, in addition to β-CD adding amount 15%, injective flow 10 mL/min and feeding temperature 70℃. Under these conditions, the spray dried powder yield efficiency was 60.26%, antioxidant retention rate was 83.92%, moisture content was 3.2% and powder dissolving time was 65 s. The results can provide practical information for the utilization of Stropharia rugoso-annulata blanching liquid in nutraceutical sources.
