Abstract
The ability of various dietary
fibers to impede lipase-catalyzed hydrolysis of tributyrin
was studied in vitro. Conditions (temperature, kind and concentration of
constituents, pH, agitation) were chosen to mimic, as closely as possible,
those prevailing in the human duodenum. Lipolysis was monitored at pH 6.0 and
37 degrees C using a constant pH titrimeter. Some fibers
inhibited lipolysis (red wheat bran, white wheat bran, oat bran and sugarbeet
fiber), whereas most did not (psyllium seed, pectin LM 12CG, carrageenan,
carboxymethylcellulose, gum arabic, and pectin slow set). Water extracts of
the fibers accounted for 32-41% of the inhibitory effect of
the two wheat brans on lipolysis and 100% of the inhibitory effect of oat
bran.
