| 中文摘要: |
| 以燕麦切粒为原料，进行超临界CO2萃取燕麦油工艺研究及燕麦油品质分析。首先，通过单因素试验探讨各因素对燕麦油萃取率的影响；其次，采用响应面法优化超临界CO2萃取燕麦油的工艺参数；最后用GC-MS分析燕麦油的脂肪酸组成并进行品质分析。结果表明：超临界CO2萃取燕麦油的最佳工艺参数为装料量50 g、静态萃取时间74 min、动态萃取时间160 min、萃取压力45 MPa、萃取温度50?℃，在此工艺条件下燕麦油萃取率可达56.99%；超临界CO2萃取的燕麦油澄清透明，呈金黄色，具有特殊的麦香味，不饱和脂肪酸含量为87.49%。 |
| 英文摘要: |
| The technology of supercritical CO2 extraction of oat oil was studied and oat oil quality was analyzed with oat diced as raw material. First of all, through the single factor experiment, the effets of various factors on the extraction rate of oat oil were studied; secondly, supercritical CO2 extraction technology parameters were optimized by response surface mothodology; finally the fatty acid composition and content of oat oil were analyzed by GC-MS and oat oil quality was analysed. The results showed that the optimal technology parameters of supercritical CO2 extraction of oat oil were obtained as follows: charge amount 50 g, static extraction time 74 min, dynamic extraction time 160 min, extraction pressure 45 MPa and extraction temperature 50?℃. Under these conditions, the extraction rate reached 56.99%. The oat oil extracted by supercritical CO2 was clear and transparent, golden yellow with special wheat flavor, and the content of unsaturated fatty acids was 87.49%. |
