Abstract:
The prebiotic ability of several rice bran fractions obtained by debranning (RBD) using human microbiota was studied in anaerobic batch cultures with agitation and pH-controlled. Fraction C (3.8-5% w/w pearling) from RBD increased the number of bifidobacteria and lactobacteria compared with the positive control, raftilose P95. RBD fermentation induced changes in the short-chain fatty acid (SCFA) profile. In addition, Fraction C revealed the highest growth of positive lactobacteria than commercial control. The present work illustrates the prebiotic capacity of RBD to modulate human microbiota and highlights that fraction C could be an economical source for use in human food as well as an interesting alternative to valorise a by-product of cereal industry.
