The production of safe food products in most cases requires a heat treatment. In the usual heating methods heat is generated outside the food and transmitted to it by conduction and/or convection. For products containing particles, like fruit or vegetable pieces, these methods often cause overheating of the liquid if sufficient heating of the solids is to be achieved: A loss of nutritional as well as organoleptic characteristics is often the result. The aim of this project is to develop an alternative heating process through the use of ohmic heating, where the heat is generated through passing an electric current through the food heating it as a result of electric resistance. Thus overheating can be avoided and food with improved taste and nutritional content, and with maintained and in some cases improved microbial safety, may be produced. This project will offer food producers a new technology to provide healthier and safer food in line with consumer demands. This will be achieved not using chemical additives but using an alternative processing technology. The companies can expect to sell products with higher market value and improved consumer acceptability. This will improve their competitiveness both on the European and the global market, with special relevance to markets such as Australia, Japan and North America, where consumers have a significant concern for quality and safety aspects.
