This study aimed to investigate the effects of dielectric‐barrier discharge (DBD) cold plasma (CP) pretreatment on Camelina sativa “Soheil cultivar” seed. A DBD plasma reactor system was employed for this purpose. The experiments were performed by taking into account variables including voltages of 15, 18, and 21 kV and times of 2, 4, 8, and 16 min. The measured properties were oil yield extraction (%), oil colour parameters (CIEL*a*b*), protein content (meal) (%), surface analysis using Scanning Electron Microscopy (SEM), and fatty acids profile of Camelina sativa. The results revealed that the CP treatment had a significant improvement in different properties of the extracted oil. It was observed that the extracted oil was increased, with the increasing time of CP exposure. The treatments of CP enhanced the oil yield from 24.3 to 31.5%, and the optimal conditions were identified as 21 kV and 16 min. Also, the maximum protein amount was observed for the samples treated by CP (39.5%). The SEM analysis showed that the cell structures of pre‐treated Camelina samples were damaged, thereby improved the oil extraction efficiency. The variations in the values of L*, a*, and b* (max‐min) were calculated to be 3.9, −2.5, and 9.7, respectively, which indicated minor changes of CP treatment on the oil colour parameters. The treated samples showed considerable changes of enhancement in linolenic and linoleic acids among poly‐unsaturated fatty acids; and a reduction in palmitic acid content, among saturated fatty acids.

介电阻挡放电冷等离子体处理的山茶种子提取油的定性和定量评估

本研究的目的是调查电介质阻挡放电（DBD）冷等离子体（CP）预处理对影响亚麻荠“Soheil栽培种”种子。为此目的使用了DBD等离子体反应器系统。通过考虑包括15 kV，18 kV和21 kV的电压以及2、4、8和16分钟的时间在内的变量来进行实验。测得的性质为油提取率（％），油色参数（CIEL * a * b *），蛋白质含量（餐）（％），使用扫描电子显微镜（SEM）进行的表面分析以及苜蓿苜蓿（Camelina sativa）的脂肪酸谱。结果表明，CP处理对提取油的不同性能有显着改善。观察到，随着CP暴露时间的增加，提取的油增加。CP处理使产油率从24.3提高到31.5％，最佳条件确定为21 kV和16分钟。另外，通过CP处理的样品观察到最大蛋白质量（39.5％）。SEM分析表明，预处理的茶花样品的细胞结构受到破坏，从而提高了采油效率。L *，a *和b *的值的变化（max-min）分别计算为3.9，-2.5和9.7，这表明CP处理对油色参数的影响很小。处理后的样品在多不饱和脂肪酸中显示出亚麻酸和亚油酸增强的显着变化。饱和脂肪酸中棕榈酸含量的降低。
