Abstract

In the last two decades, pulsed electric fields (PEF) have successfully been introduced into the food industry, as one of the most promising and "game changing" technologies. This review is devoted to the recent applications of pulsed electric fields used in processing potatoes. The potato processing market size was estimated to be ca. USD 24.83 billion (2018) and with an annual growth rate of 5.2%. The physicochemical characteristics of potatoes and the specificity of potato processing lines makes a pulsed electric field very versatile and flexible allowing one to achieve different technological aims by its implementation into technological lines. In this paper, a short analysis of the potato structure and its nutritional properties, applications of moderate electric fields, ohmic heating, and pulsed electric fields are presented. Moreover, the basic electroporation effects, metabolic responses, texture modification and different PEF assisted processes applied to the potato are discussed. Finally, some examples of commercial applications and a brief description of the available equipment for the PEF processing of potatoes are presented.

脉冲电场在马铃薯加工中的应用:实例及设备设计

在过去的二十年里，脉冲电场(PEF)作为最有前途和“改变游戏规则”的技术之一，已成功地引入食品工业。本文综述了脉冲电场在马铃薯加工中的最新应用。马铃薯加工市场规模估计约为248.3亿美元(2018年)，年增长率为5.2%。马铃薯的物理化学特性和马铃薯加工生产线的特殊性使得脉冲电场非常通用和灵活，允许人们通过在工艺生产线中实施脉冲电场来达到不同的技术目的。本文简要分析了马铃薯的结构和营养特性，介绍了中等电场、欧姆加热和脉冲电场的应用。此外，还讨论了马铃薯的基本电穿孔效应、代谢响应、结构修饰以及不同的PEF辅助工艺。最后，介绍了马铃薯PEF加工的一些商业应用实例和现有设备的简要描述。
