The organic food market is one of the fastest growing food sectors in the world. A major part of the organic food consumed is processed. Therefore, the increasing demand of organic food represents a major challenge for the organic food industry. With the exclusion of a positive list of additives and technological aids, mandatory standards for the processing of organic food are lacking in the EU Regulation, as well as indications that can represent a guide for the processors in the selection of appropriate technologies and innovations in line with the organic principles. To contribute to the sustainable innovation in the organic food sector, the ProOrg project has the objective to develop a flexible and practicable Code of Practice (CoP) for processors of organic foods, as well as labelling organizations. The CoP aims to provide the operators with strategies and tools for making decisions that can help them to take the best choice for careful processing methods and formulations with a limited use of additives, while addressing the organic principles, high food quality, low environmental impact and high degree of consumer acceptance. To labelling organizations, the CoP will provide an assessment and decision support tool to evaluate the compliance of process innovations with the general organic principles.
