八角籽壳油脂的提取及残渣利用性分析
       摘要:用索氏法分别提取八角籽和果壳挥发油,用气相色谱法测定了挥发油中八种脂肪酸的含量,与常见植物油比较,八角籽挥发油与其他食用植物油脂肪酸组成类似,而八角壳油的脂肪酸含量较低,作香料仍然是首选。即按照食用植物油卫生标准进行检测,并设计了实验室精炼油脂的简单工艺,发现稍加精炼的八角籽油可放心食用。最后分析了残渣八角籽粕和八角壳渣的部分质量指标,探讨了作为动物饲料的可行性。结果表明八角籽粕的蛋白质、粗纤维含量与大豆皮相似,其他理化指标符合饲料卫生标准的要求。参照大豆皮的利用情况,提出八角籽粕的应用构想。
       关键词:八角挥发油、脂肪酸分析、油脂检测、精炼、残渣分析
