Sunflower oil pilot-production based on local raw materials assisted by pulsed electric field (PEF), which is produced in terms of oil yield, extraction kinetics and chemical parameters on pilot scale mill with continuous-flow material treatment developed in this work. PEF treatment with electric field strength 7 kV/cm and energy consumption of 6.1 kJ/kg on the sunflower seed increased the value of extraction yield by 2.3%, with respect to a control one. Extraction parameters obtained by pulsed electric field treatment showed that diffusion coefficient, micropore volume, and disintegration index were significantly higher than control ones (on 55.5%, 32.2% and 43% respectively). Furthermore, the use of PEF treatment had minor effects on the main chemical characteristics (acid and peroxide value etc.) and color parameters of the sunflower oil. On the basis of obtained results, it can be concluded that PEF could be a high potential industrial technology to improve enriched in human-health-related compounds of sunflower oil.

Practical applications

The obtained results are relevant for specialists using PEF technologies and developing PEF equipment. The data will also be in demand when calculating the economic efficiency of PEF application on an industrial scale.

脉冲电场辅助葵花籽油的中试生产：对油得率，萃取动力学和化学参数的影响

基于脉冲电场（PEF）辅助的本地原材料的葵花籽油中试生产，是在这项工作中开发的具有连续流物料处理的中试规模磨机上根据油的收率，萃取动力学和化学参数而生产的。相对于对照种子，在向日葵种子上进行7 kV / cm的电场强度和6.1 kJ / kg的能量消耗的PEF处理可使提取收率提高2.3％。通过脉冲电场处理获得的提取参数表明，扩散系数，微孔体积和崩解指数显着高于对照（分别为55.5％，32.2％和43％）。此外，使用PEF处理对葵花籽油的主要化学特性（酸和过氧化物值等）和颜色参数影响较小。

实际应用

获得的结果与使用PEF技术和开发PEF设备的专家有关。在工业规模上计算PEF应用的经济效率时，也将需要该数据。
