    • In a method of preserving a food product by applying high pressure, the food product (1) is forced through a treatment system (2) having an entrance (3) and an exit (4) while a pressure difference of at least 10 MPa is substantially maintained between the entrance and the exit. The product (1) is subjected to a varying electric and/or magnetic field. A treatment system with a plurality of treatment chambers is used, wherein the treatment chambers are electrically connected to reduce impedance variations of the treatment system during the preserving of the food product. For the food product flow the treatment chambers are series connected. An apparatus (10) for preserving food products comprises at least one treatment system (2) having an entrance (3) and an exit (4), a high-pressure generating means (11) for forcing a product (1) through the treatment system, while substantially maintaining a pressure difference of at least 10 MPa between the entrance and the exit, and means (5) for generating a varying electric and/or magnetic field and for subjecting the product to the varying electric and/or magnetic field. The treatment system comprises a plurality of treatment chambers (2) which are electrically interconnected to reduce impedance variations of the treatment system and which are series connected for the food product flow.
    • 在通过高压保存食品的方法中,食品(1)被迫通过具有入口(3)和出口(4)的处理系统(2),而至少10MPa的压力差为 基本保持在入口和出口之间。 产品(1)经受变化的电场和/或磁场。 使用具有多个处理室的处理系统,其中处理室电连接以减少在保存食品期间处理系统的阻抗变化。 对于食品流动,处理室串联连接。 用于保存食品的设备(10)包括至少一个具有入口(3)和出口(4)的处理系统(2),用于迫使产品(1)通过处理的高压产生装置(11) 系统,同时在入口和出口之间基本上保持至少10MPa的压差,以及用于产生变化的电场和/或磁场并使产品经受变化的电场和/或磁场的装置(5)。 处理系统包括多个处理室(2),其被电互连以减少处理系统的阻抗变化并且串联连接到食品流。
