The Framework Regulation (EC) No 1935/2004 requires that food packaging does not transfer a taste or odor to food. 

Smithers has 30 years' experience in the investigation of packaging taints. The laboratory has contributed over the years to numerous text books on the subject. Taint investigations often require a detailed knowledge of typical packaging compositions to allow abnormal compositions that might be responsible for a taint to be recognised. 

Specialist expertize and analytical techniques for taint investigation

The concentrations required to cause a taste or odor may be as low as a few parts per billion. This requires dedicated, specialist sensitive analytical equipment (Gas Chromatography Mass Spectrometry). The chemical or chemicals responsible are usually not known so that several analytical methods may be required. Smithers has the specialist expertise, experience and laboratory capabilities necessary to carry out this type of investigation.

Taint investigations require that the subjective nature of the human senses also be taken into consideration. Interpretation of the results often requires access to databases of human taste and odor thresholds in a range of media as well as a sound knowledge of the typical types and concentration ranges of chemicals used in packaging. 

Packaging performance

Smithers has access to a wide range of analytical techniques allowing the identification and quantification of chemicals in a wide range of packaging materials and foods. 

In combination with the expertise and equipment for packaging technical investigation available at Smithers, we help clients solve numerous packaging related problems. Common issues include packaging performance, product contamination or packaging related complaints.

We help with:
