| 中文摘要: |
| DHA是一种重要的功能性ω-3多不饱和脂肪酸.我国卫生部相继批准了寇氏隐甲藻、裂壶藻、吾肯氏壶藻DHA藻油为新资源食品.收集并分析了9个商品化DHA藻油的脂肪酸含量,结合文献数据,发现通过商品化DHA藻油的脂肪酸特征推测其微藻属名是可行的.其中寇氏隐甲藻DHA藻油中长链多不饱和脂肪酸只含DHA,几乎不合DPA.裂壶藻与吾肯氏藻DHA藻油中长链多不饱脂肪酸主要以DHA和DPA为主,DHA/DPA比例随藻种而恒定,几乎不随发酵条件而有明显变化;DHA/DPA比例在2～3的DHA藻油多半来自裂壶藻;DHA/DPA比例在4～6的DHA藻油既可能来自裂壶藻也可能来自吾肯氏壶藻. |
| 英文摘要: |
| DHA is an important functional omega-3 polyunsaturated fatty acid.Chinese Ministry of Health has successively approved microalgae DHA oils produced by Crpthecodinium cohnii,Schizochytrium sp.,Ulkenia sp.as novel resource food.Nine commercial microalgae DHA oils were collected and their fatty acid compositions were analyzed.The analysis result and related literature data showed that estimating microalgae genus through the fatty acid composition of the commercial microalgae DHA oil was possible.The long chain... |
