Resumo(s)
Sugar beet pulp (SBP) and lemon peel wastes (LPW) were used to obtain two mixtures of
pectic oligosaccharides (denoted as SBPOS and LPOS, respectively). Oligogalacturonides in
LPOS showed a larger molecular weight, higher degree of methylation and lower degree of
acetylation than the ones in SBPOS. The suitability of pectic oligosaccharides, pectins from
SBP and LPW and commercial FOS for causing prebiotic effects were compared by in vitro
fermentation and fluorescence in situ hybridization using human faecal inocula and eight
different probes. The joint populations of bifidobacteria and lactobacilli increased from 19%
up to 29%, 34% and 32% in cultures with LPOS, SBPOS and FOS, respectively. Faecalibacterium
and Roseburia also increased their counts with all the substrates (especially with LPOS). The
highest concentrations of organic acids were observed in media containing oligosaccharides.
This work confirms that pectic oligosaccharides present better prebiotic properties
than pectins, and similar or better than FOS.
