Fig. 5From: Metabolism and bioavailability of newly developed dietary fiber materials, resistant glucan and hydrogenated resistant glucan, in rats and humansChanges of breath hydrogen excretion after ingestion of RG or HRG in healthy human subjects. FOS, fructooligosaccharide; RG, resistant glucan; HRG, hydrogenated resistant glucan. Test solution containing 30 g of purified RG or HRG was ingested by 10 healthy subjects shown in Fig. 4 after overnight fasting, and end-respiratory gas (750 ml) was collected using collection bag at 1-h intervals for 14 h after ingestion (a). Furthermore, to evaluate the available energy test solution containing 5 g of purified RG or HRG was ingested by healthy subjects after overnight fasting (b). FOS (5 g) was used as a typical oligosaccharide which is nondigestible and completely fermentable. Figure 5-a shows the change of hydrogen excretion 14 h after ingestion of 30 g of test substance, and Fig. 5-b shows the change of hydrogen excretion 14 h after ingestion of 5 g of test substance. Values were means ± SD. *, The excretion of breath hydrogen in RG or HRG ingestion were significantly lower versus that in FOS ingestion, at P < 0.05 by Steel method. There was no significantly difference between RG and HRG by Steel-Dwass methodBack to article page
