Contamination problems can arise from cleaning a production line, direct or indirect contact with an external aromatic source (processing, environment, etc.), a raw material itself having a defect, or the premature aging of a product. Among the most frequent causes are contaminations related to packaging.
Indeed, new restrictions related to increasingly strict regulations compel companies to find new packaging materials for the packaging of their products. However, even if the material used is validated for food contact, some non-toxic aromatic molecules can alter the aromas of the packaged food product; this is the case with certain glues or inks.
Thanks to adapted equipment and specific interpretation methods, we are able to perform the analyses necessary for the study of VOCs and the products from which they emanate. The approach most often combines physico-chemical analyses with tests conducted by a trained sensory panel (in coordination with the sensory analysis laboratory).
