摘要

The Food Safety and Technology Research Centre under the Department of Applied Biology and Chemical Tech- nology of The Hong Kong Polytechnic University (PolyU) has developed a new method for rapid authentication of edible oils and screening of gutter oils. Authentication of edible oils has been a long-term issue in food safety, and be- comes particularly important with the emergence and widespread use of gutter oils in recent years. However, the conventional analytical approach for edible oils is not only labor intensive and time consuming, but also fails to provide a versatile solution for screening of gutter oils. By setting up a simple analytical protocol and a spectral library of edible oils, the new approach is able to determine the authenticity of a labeled edible oil sample and hence screened gutter oils within five minutes.
