摘要
以白胡椒粉为原料,研究了超声波辅助乙醇提取白胡椒油树脂的工艺条件,考察了提取溶剂乙醇浓度、固液比、提取温度和提取时间对白胡椒油树脂得率的影响。实验结果表明:用90%(v/v)乙醇为提取介质,在固液比为1:8(g/mL)、55℃温度下超声提取60min,白胡椒油树脂得率可达10.28%。
The process technique of ultrasonic assisted ethanol extraction for white pepper oleoresin with white pepper powder as raw materials was studied. The affects of ethanol concentration, extraction temperature, extraction time, ratio of solid to liquid to extraction yield were investigated. The experimental results showed that the yield of white pepper oleoresin can reach to 10. 28% by using 90%(v/v) ethanol as extracting medium, the ratio of solid to liquid (g/mL) is 1:8, ultrasonic extraction time is 60 mins under 55 ℃.
