Introduction

FIBEBIOTICS SUMMARY – THE WORK BEING UNDERTAKEN AT TEAGASC MOOREPARK

 

PROJECT LEADER: DR. CATHERINE STANTON

In this project, we plan to investigate the effects of food-grade microbial fibre/exopolysaccharides (EPS) on the human immune system (in vitro and in vivo), following their isolation and purification from fermentation media. EPS producers from the genera Lactobacillus and Bifidobacterium will be used, and the microbial fiber products will be extensively characterised, including structure determination, including sugar composition, branching, degree of polymerization and molecular weight determination. The impact of exposure of the isolated EPS on gut microbiota (prebiotic activity) will be tested in vitro and in vivo. The technofunctional properties of isolated EPS will be assessed in solution, and processes to produce fermented food products enriched in microbially produced EPS will be developed, and the food products assessed for quality and sensory attributes.
