背景资料：脉冲电场（PEF）是一种有吸引力的和有效的非热技术，可以提高功能性，可提取性和营养有益化合物的回收。对于工业PEF食品加工，高电场一致性对于连续操作和短期内经济的投资回报非常重要。范围和方法：由于缺乏可靠和更实用的电气系统，工业规模的技术吸收仍然很低。因此，设计一个特定于应用和成本效益的电气系统是必不可少的商业使用这种新技术。本文综述了高压脉冲电场食品加工中电气系统的要求和发展，主要发现和结论：高压脉冲电场系统的工艺参数和控制变量不仅对电气系统的设计至关重要，而且对食品科学专家也至关重要。对实验程序的不同工程方面的描述不充分或不充分，是允许在其他实验室复制工作的障碍。本文介绍了食品加工中的关键工艺参数和专用设备的设计方法，为该技术的设计者和研究者提供指导。
Background: Pulsed electric field (PEF) is an attractive and efficient non-thermal technology that can advance functionality, extractability, and retrieval of nutritionally beneficial compounds. For industrial PEF food processing, high electric field consistency is of importance for continuous operation and an economical return-of-investment within a short period.Scope and approach: The technology uptake at an industrial scale is still low due to the shortage of reliable and more practical electrical systems. Therefore, designing an application-specific and cost-effective electrical system is essential for commercial use of this novel technology. This review describes the requirements and developments of the electrical systems employed in PEF food processing.Key findings and conclusion: The process parameters and control variables of the PEF system are not only critical for the designing of the electrical systems but also for the experts of the food sciences. Inadequate or insufficient description of different engineering aspects of experimental procedures is a hindrance in allowing the work to be reproduced in other laboratories. This review describes the critical process parameters and the designing methodology of the specialized equipment required in food processing as a guide for the designers and the researchers of this technology.
