MEFPROC Project
MEFPROC - Improving Sustainability in Food Processing using Moderate Electric Fields (MEF) for Process Intensification and Smart Processing
The adoption of novel sustainable, innovative processing solutions capable of producing microbiologically safe, high-quality products is essential for future economic growth and advancement in the European Food Industry. Novel mass transfer (e.g. extraction/impregnation) and volumetric heating (e.g. softening, coagulation, cooking or heat processing) operations based moderate electric field (MEF) application to foods represent an extremely energy efficient yet low cost group of applications which will have a definite role in this innovation revolution. Unlike high voltage pulsed electric fields (PEF), a technology which has received considerable attention in recent years, MEF involves a simpler more direct application of electrical current (i.e. no capacitors, pulse forming networks etc.) which is in the form of AC (vs. DC in PEF) at considerably lower field strengths (i.e. V/cm vs. kV/cm) than PEF. Further process intensifications and marginal gains are possible if MEF is applied in combination with ultrasound (US).
The consortium consists of (1) leading European researchers in electro processing, ultrasound, process control and computer modelling (2) MEF and US equipment manufacturers (3) food manufacturers interested in utilising MEF with US for mass transfer and/or heating applications but prevented from doing so by gaps in knowledge.
Objectives of the project
The overriding objective of MEFPROC project is to bridge gaps in scientific and technical knowledge currently preventing uptake of MEF and US by the food industry providing innovative and sustainable processing solutions for European Food Manufacturers in a host of sectors. Key to achieving this aim will be the quantification and demonstration of yield gain and reduced energy consumption with MEF (and US enhanced MEF) compared to existing heating and/or mass transfer operations. To assist commercial uptake, dissemination and information generation to counteract non-technical barriers to uptake are other project aims.
