The aim of this project was to examine the effect of gastro-duodenal digestion on the allergenic potential of the major food allergen Ber e 1 (2S albumin) from Brazil nut. The model food allergen, Ber e 1, was purified at Institute of Food Research (IFR) and digested using their simulated gastro-intestinal digestion model. Examination of the allergenic potential of the intact and digested Brazil nut allergen was performed at the National Food Institute. The project included a scientific visit at IFR for seven weeks.
