采用超声波辅助包埋法,利用β-环糊精的特殊空腔结构对超临界CO2萃取的姜油树脂进行包合,以姜油树脂的包埋率为指标,在单因素试验的基础上,利用响应曲面法对影响包埋率的3个主要因素即超声波功率、包埋温度和包埋时间进行了优化。分析表明最佳工艺参数为:姜油树脂(mL)∶β-环糊精(g)为1∶8、超声波功率197.5W、包埋温度48℃、包埋时间26min,姜油树脂包埋率93.56%,实测值与预测值符合良好。 Using ultrasonic-assisted embedding method, the special cavity structure of β-cyclodextrin was used to pack the ginger oleoresin extracted by supercritical CO2. Taking the embedding rate of ginger oleoresin as an index, on the basis of single factor experiment, The response surface method was used to optimize the three main factors affecting the embedding rate, namely ultrasonic power, embedding temperature and embedding time. The results showed that the optimal parameters were as follows: ginger oil (mL): β-cyclodextrin (g) 1: 8, ultrasonic power 197.5W, embedding temperature 48 ℃, embedding time 26min, ginger oleoresin embedding rate 93.56%, the measured value is in good agreement with the predicted value.
