Prebiotic potential of a refined product containing pectic oligosaccharides

Evaluation of the prebiotic potential of arabinoxylans from brewer’s spent grain

“…The only exception was faecal cultures from donor 1 containing AX1. C. coccoides-E.rectale group was also considered in this work, and AX from BSG had a stimulatory effect (1.2 to 1.9 log-fold increase) and similar results were observed in the fermentation of pectic polysaccharides from apple pomace (Gullón et al 2011a) and AX from wheat (Hughes et al 2007). …”

“…In all these assays, lactate was then completely depleted confirming that this acid is an intermediary product that can be converted into acetate, propionate and butyrate by common intestinal microbiota, acting in a crossfeeding mechanism as it was previously reported (Gullón et al 2011a(Gullón et al , b, 2014.…”

“…Both AX1 and AX2 presented a higher stimulatory effect of bifidobacterial population than FOS but AX2 showed a clear positive effect over AX1. This difference was probably due to the polymers' structure, since AX2 was composed of longer and less branched polymers than AX1; although the presence of glucose-based oligossacharides was in very low amount (0.5 g/L), they could also have contributed to the growth of bacterial populations since it was reported that glucooligosaccharides were preferentially metabolised by intestinal bacteria (Gullón et al 2011a(Gullón et al , 2014.…”

Prebiotic properties of crude oligosaccharide prepared from enzymatic hydrolysis of basil seed gum

“…Viable cell counts of Enterobacteriaceae group obviously increased but non-significant (p>0.05) in basal medium with glucose, while that in basal medium with crude basil oligosaccharide increased significantly (p<0.05). The effect of crude basil oligosaccharide on stimulation of LAB growth and suppression of pathogen growth was similar to that by FOS, inulin (19), and pectic oligosaccharides (32). They also found higher production of short chain fatty acids (SCFAs), i.e.…”

Continuous Membrane Bioreactor (CMBR) to Produce Nanoparticles from Milk Components

“…These results confirm that coupling two NF stages (discontinuous diafiltration followed by concentration) is a suitable alternative for obtaining OS concentrates. The refined product obtained in this work showed degrees of purity in the range reported for commercial OS and was assayed for its prebiotic potential and the results showed the promotion of beneficial bacterial growth (Gullón et al, 2011).…”
