Research Interests
These interests lie within the general field of food toxicology and food safety assurance. Specific areas of current research include:
1. the role of the gastro-intestinal tract and gut microflora in the metabolism and toxicology of food additives and contaminants;
2. the formation and toxicological significance of interaction products formed from food components/additives during processing and cooking (including mutagenic pyrolysis products formed on heating, and interaction products of sulphites and of nitrates in foods);
3. Mechanisms of action of food borne mutagens and antimutagens;
4. Peroxisome proliferation and its significance in the toxicology of some terpenoid food flavours and of packaging materials.
Collaborative research programmes have been/are being undertaken with the British Industrial Biological Research Association, the Istituto Nazionale della Nutrizione, Rome, and the Institut fur Tierphysiologie und Tierenahrung der Georg-August Universitat zu Gotingen, FDR.
Publications
More than 120 publications related to the toxicology and safety evalution of food additives and contaminants. In additiona, prepared toxicological monographs for WHO published in WHO Food Additive Series.
