摘要: 本文对超声波辅助提取甘薯中的活性成分β-胡萝卜素工艺进行了研究。研究结果表明,超声波提取β-胡萝卜素的最佳条件为:室温条件下,提取溶剂为丙酮:石油醚=3:7,提取时间为25min,料液比为1:4,提取次数3次。结果证明,超声波提取对热敏性和光敏性物质β-胡萝卜素的提取效果优于自然浸提法,节省了溶剂用量和提取时间,是一种切实可行的β-胡萝卜素生产方法。

Abstract: The extraction technics of β-carotin with ultrasonic auxiliary in sweet potatoes were studied in this paper. The results showed that the procedures are optimal to extract β-carotin with ultrasonic auxiliary: at room temperature, using acetone- petroleum ether(3:7) as solvents, and then extracted 25min for 3 times with the proportion of material and solvent(1:4). The extraction method of β-carotin with ultrasonic auxiliary is superior to that of general saturation. The process with ultrasonic auxiliary costs less solvent and time. It proves to be a feasible way to extractβ-carotin.
