摘要:

以成熟海蓬子种子为原料、石油醚为提取溶剂,采用微波辅助法提取海蓬子籽油。在微波温度、微波时间、料液比和微波功率对海蓬子籽油得率影响4 个单因素试验的基础上,通过响应面法优化微波辅助提取海蓬子籽油的最佳工艺条件。结果表明,微波辅助提取海蓬子籽油的最佳工艺条件为:微波温度55 ℃、微波时间5 min、料液比1∶10(g/mL)、微波功率700 W。在此条件下,海蓬子籽油得率为32.58%。与传统索氏抽提法相比,微波辅助提取海蓬子籽油的得率提高了0.15%,而提取时间仅为索氏抽提法的1.39%。

Abstract:

The microwave-assisted extraction of seed oil from Salicornia bigenlovii Torr. using petroleum ether as the
extraction solvent was optimized by response surface methodology. The extraction yield of seed oil was investigated with
respect to extraction temperature, extraction time, solid-to-liquid ratio, and microwave power. The results showed that the
optimal extraction conditions for Salicornia bigenlovii Torr. seed oil were as follows: temperature, 55 ℃; extraction time,
5 min; solid-to-liquid ratio, 1:10 (g/mL); and microwave power, 700 W. Under these optimal conditions, the extraction yield
of Salicornia bigenlovii Torr. seed oil was 32.58%, a 0.15% increase over that obtained by traditional Soxhlet extraction.
Moreover, the extraction time was only 1.39% of that required by Soxhlet extraction.

Key words: Salicornia bigenlovii Torr., seed oil, microwave, extraction, response surface methodology
