摘要:

采用正交试验设计优选正己烷微波法提取八角挥发油的最佳工艺条件为固液比1:15(g/ml)、微波时间5min、微波功率640W,与常规的索氏提取法相比,该法具有快速、节能的特点。对八角油进行脂肪酸成分分析,结果表明,八角籽油和其他食用植物油的脂肪酸组成类似,按照油脂生产许可证发证检验的项目进行检测,发现稍加精炼的八角籽油可放心食用;八角壳油脂中的脂肪酸含量较低,与其他食用植物油差别大,做香料、调味料仍然是首选,而不适合做普通的食用植物油。

Abstract:

Volatile oil was extracted from star anise seeds or shell using hexane with the aid of microwave. The optimal extraction process determined using orthogonal array design was based on 640 W microwave treatment for 5 min with a material/liquid ratio of 1:1.5. Compared with traditional extraction methods, microwave-assisted n-hexane extraction had characteristics of high efficiency, fast speed and energy-saving. Meanwhile, the analysis of fatty acids in anise seed oil revealed similar compositions with commercially available vegetable oil. Therefore, refined anise seed oil was qualified to be edible according to requirements for human consumption. Furthermore, fatty acids in anise seed shell oil were relatively lower than other edible oils, which made it as an excellent material for fragrance and flavor ingredients.

Key words: volatile oil from anise, microwave-assisted extraction, fatty acid, edibility analysis
