| 为突破传统超临界工艺“高木脂素含量-高提取率”难以同步的瓶颈，基于超临界CO2对芝麻木脂素的选择性溶解特性，建立一步法富集芝麻素、芝麻林素并兼顾二者提取率的工艺，同时实现残粕的高值化利用。采用单因素实验考察了超临界 CO2萃取压力、萃取温度、CO2流量对芝麻木脂素含量与提取率及芝麻油提取率的影响，进一步采用响应面法对工艺条件进行优化。在此基础上，对所得残粕进行变压变温超临界CO2二次萃取以提取残留油脂。结果表明：超临界CO2一步萃取富集芝麻木脂素最优工艺条件为萃取压力19.8 MPa、萃取温度55 ℃、CO2流量4.4 L/min，在此条件下芝麻油中芝麻素、芝麻林素含量分别达到2.98%和1.24%，较原料分别提高6.39倍和6.95倍，二者提取率分别为66.29%和71.26%；所得残粕在萃取压力50 MPa、萃取温度35 ℃、CO2流量4 L/min下经超临界CO2二次萃取提油，总油脂提取率达94.88%，二次萃取油可作为普通食用油。本工艺实现了“高木脂素含量-高提取率”同步优化，且通过一次装料，变压变温分段萃取，实现了高木脂素芝麻油和低木脂素芝麻油的高值化利用。 |

| To overcome the bottleneck of conventional supercritical technology, which struggles to simultaneously achieve both high lignan content and high extraction yield, a one-step process was established based on the selective solubility of supercritical CO2 for sesame lignans,which enabling the enrichment of sesamin and sesamolin while balancing their extraction yields, along with the high-value utilization of the residual meal. Single-factor experiments were conducted to investigate the effects of supercritical CO2 extraction pressure, extraction temperature, and CO2 flow rate on the content and extraction yield of sesame lignans, and extraction yield of sesame oil, followed by response surface methodology for process optimization. Subsequently, the residual meal was subjected to a secondary supercritical CO2 extraction under variable pressure and temperature conditions to recover residual oil. The results demonstrated that the optimal conditions for the one-step supercritical CO2 extraction enrichment of sesame lignans were extraction pressure 19.8 MPa, extraction temperature 55 ℃, and CO2 flow rate 4.4 L/min. Under these conditions, the contents of sesamin and sesamolin in sesame oil reached 2.98% and 1.24%, respectively, representing increases of 6.39-fold and 6.95-fold compared to the raw material, with corresponding extraction yields of 66.29% and 71.26%. The residual meal was further subjected to secondary supercritical CO2 extraction at 50 MPa, 35 ℃, and 4 L/min, achieving a total oil extraction yield of 94.88%, and the secondary extracted oil could serve as conventional edible oil. This process successfully achieves the simultaneous optimization of high lignans content and high extraction yield. Moreover, through single-batch loading with segmented extraction under variable pressure and temperature, it enables the high-value utilization of both high-lignan sesame oil and low-lignan sesame oil. |
