| 中文摘要: |
| 测定了烤鳗加工废弃物鳗骨的成分，系统研究了鳗骨为原料提取鳗骨油，经盐形成法和尿素包合法制取鱼油多不饱和脂肪酸，喷雾干燥法制备鳗油微胶囊的工艺条件。结果表明，该工艺简便易行，鳗骨油提取完全率达７６％以上；纯化后鳗骨油脂肪酸中ＥＰＡ，ＤＨＡ含量由７．４％提高至４５％以上，总回收率为６４％；微胶囊制品中ＰＵＦＡ含量达２６．２％左右，其抗氧化稳定远高未经包囊的混合物。 |
| English Summary: |
| The contents of the components in waste eel bone from roast eel were determined. Optimal conditions for extracting eel bone oil from waste eel bone as raw material, purifing the polyunsaturated fatty acids (PUFA) concentrates from eel bone oil via salt-forming with urea complexation, and preparation of microcapsules containig PUFA concentrates from eel bone oil by spray drying were investigated systematically. The results showed that the technique was easy to carry out, the complete yield for extracting eel bone oil was above 76%, the contents of EPA and DHA in PUFA purified from eel bone oil increased from 7. 4% to about 45%, the recovery of EPA plus DHA was 64% , the content of PUFA from eel bone oil in the microcapsuls was about 26. 2%, and its antioxidative stability was higher than that of mixture of PUFA concentrates without capsulizing. |
