| 旨在为油莎豆油的高效提取提供参考，以油莎豆为原料，采用动态超高压微射流辅助正己烷提取油莎豆油，通过单因素试验研究了微射流压力、提取温度和提取时间对油莎豆油得率的影响，并采用响应面试验对提取工艺进行优化；对比了动态超高压微射流辅助正己烷提取与单一正己烷提取对油莎豆油得率的影响，并对油莎豆油的品质进行了分析。结果表明：动态超高压微射流辅助正己烷提取油莎豆油的最佳工艺条件为微射流压力110 MPa、提取温度50 ℃、提取时间7 min，在此条件下油莎豆油得率为22.81%；与单一正己烷提取相比，动态超高压微射流辅助正己烷提取油莎豆油得率更高，提取温度更低，提取时间更短；动态超高压微射流辅助正己烷提取的油莎豆油的理化指标及脂肪酸组成及含量均符合油莎豆油行业标准（LS/T 3259—2018）的要求。综上，动态超高压微射流辅助正己烷提取法是一种高效的油莎豆油提取方法。 |

| In order to provide a reference for the efficient extraction of Cyperus esculentus oil, Cyperus esculentus oil was extracted by dynamic ultra high-pressure microfluidization assisted n-hexane method. The effects of microfluidization pressure, extraction temperature, and extraction time on the yield of Cyperus esculentus oil were studied through single factor experiments, and the extraction process was optimized using response surface methodology. The effects of dynamic ultra high-pressure microfluidization assisted n-hexane method and single n-hexane extraction on the yield of Cyperus esculentus oil were compared, and the quality of Cyperus esculentus oil was analyzed. The results showed that the optimal extraction conditions were obtained as follows: microfluidization pressure 110 MPa, extraction temperature 50 ℃, and extraction time 7 min. Under these conditions, the yield of Cyperus esculentus oil was 22.81%. Compared with single n-hexane extraction, the dynamic ultra high-pressure microfluidization assisted n-hexane method had higher yield, lower extraction temperature, and shorter extraction time. The physicochemical indicators and fatty acid composition and content of Cyperus esculentus oil extracted by dynamic ultra high-pressure microfluidization assisted n-hexane method met the requirements of the Cyperus esculentus oil industry standard (LS/T 3259-2018). In summary, dynamic ultra high-pressure microfluidization assisted n-hexane method is an efficient method for Cyperus esculentus oil extraction. |
