Identification of the breath-signature of chitin-glucan insoluble fiber in healthy volunteers

Rationale: The fermentation of dietary fiber (DF) leads to the production of bioactive metabolites, the most volatile ones being excreted in the breath. The aim of this study was to analyze the profile of exhaled breath volatile metabolites (BVM) after supplementation with the insoluble DF chitin-glucan (CG) in healthy individuals.
