The effect of inulin and fructo-oligosaccharide supplementation on the textural, rheological and sensory properties of bread and their role in weight management: A review

摘要

There is evidence that fructo-oligosaccharides (FOS) and inulin can impart a range of health benefits if consumed on a regular basis. The health benefits include increased mineral absorption and improved immune response and while there is mounting evidence that prebiotics play a role in\udcolorectal cancer prevention, their role in feeling of satiety and weight management is still being investigated.\udIn this review we look at the evidence published so far on FOS or inulin supplementation and weight management. We also establish whether prebiotic enriched breads are feasible in terms of dough machinability, bread characteristics and consumers acceptance. Addition of inulin to bread generally resulted in smaller loaves with a harder crumb and darker colour. The limited sensory studies on those products reflect those findings and acceptability\uddecreased with inulin content. However, a fortification of 5% seems achievable. Despite evidence that yeast invertase and dry heat degrade inulin, the extent to which this is the case and whether the prebiotics maintain their activity is not known. There is still a great deal of work to be done to establish whether a bread prepared with enough\udinulin to retain a significant activity can be manufactured without compromising consumer acceptance.
