摘要
为探讨超临界萃取条件对鹿油萃取率的影响,以鹿肉为原料,通过单因素试验和正交试验考察了萃取压力、萃取温度、萃取时间对鹿油提取率的影响.研究结果表明,最佳萃取条件为萃取温度45℃、萃取压力40 MPa、萃取时间150 min.对鹿油理化性质指标和脂肪酸组成的测定结果表明,超临界萃取的鹿油酸价低,含有多种脂肪酸,其中不饱和脂肪酸总含量为41.94%.
An experimental study was conducted to explore the effect of supercritical extraction conditions on the extraction rate of deer oil. Deer venison was used as raw material in this study. The extraction pressure, extraction temperature, and extraction time on the yields were studied by single factor experi- ments and orthogonal tests. The results showed that the highest extraction rate could be reached at an ex- traction temperature of 45℃, under an extraction pressure of 40 MPa, and the extraction time was 150 min. After the measuration of physical and chemical property indicators of the deer oil and the analysis of the composition of the fatty acid, it was found that the deer oil acquired through supercritical extraction had a good color and low acid value and contained a variety of fatty acids, of which the total unsaturated acids reached 41.94%.
