WP 4 Chemical Hazards
To reduce (industrial) chemical adulterations and to ensure authenticity of spices and herbs by evaluation and improvement of non-targeted fingerprinting methods.
Aim
To develop a rapid and cost-efficient set of methodologies for the detection of natural, accidental and deliberate contamination of spices and herbs with (unexpected) chemical agents.
Background
Traditional strategies to guarantee food quality and safety and to detect adulterations are typically based on wet chemistry and suffer from a number of disadvantages. As such, there is a continuing demand to investigate ways to combine existing testing methods and emerging technologies into a comprehensive analytical strategy for early quality and safety assurance in the food chain.
Methodology
The application of several spectrometric and spectroscopic fingerprinting techniques will be evaluated using a representative set of authentic and adulterated samples. The fingerprinting data will be used to develop and evaluate various chemometric classification techniques that allow distinguishing authentic samples from adulterated/contaminated samples. The application of HPLC-MS/MS to determine the identity and composition will be evaluated.
