PEF Processing of Fruits, Vegetables, and their Products
Fruit and vegetables are an important component of a healthy diet and, if consumed daily in sufficient amounts, could help in preventing major diseases. Phytochemicals and antioxidants found in fruits and vegetables are capable of neutralizing free radicals and play a major role in the prevention of certain diseases. Pulsed electric fields (PEF) is an emerging electro-pulse technology that has been established to be a suitable method for food preservation, hence receiving worldwide attention of food professionals. PEF is an emerging electro-pulse technology that has been established to be a suitable method for food preservation, hence receiving the worldwide attention of food professionals. Non-thermal food processing technologies have a promising application as an alternative to thermal technologies, by improving safety whilst maintaining product quality and economic feasibility. PEF has the potential to pasteurize several foods by the use of high-voltage short pulses maintained at temperatures from 30°C to 40°C, having an effect similar to pasteurization, yet without the thermal component.
