This session focuses on contaminants relevant to current process practices, mitigation strategies and regulatory aspects. Contaminants comprise environmental pollutants such as heavy metals, pesticides, PCBs, dioxins or PAHs, and process contaminants such as 3-MCPD- and glycidol esters, mineral oil hydrocarbons, and phthalates. Examples of current and new practices applied to seed conditioning, seed preparation, extraction, degumming, physical refining, alkali refining, bleaching, short-path evaporation, deodorization, interesterification, fractionation and fractional distillation will be presented in this session.
