Abstract
The effect of maltitol admininstration to rat was studied on breakdown of ${\alpha}-glycoside$ linkage with intestinal mucosa or pancreatic enzymes and induction of hepatic polyol dehydrogenase activities. Maltitol was contained as 13% or 26% in diet, and was administrated to rat for 9 weeks. This report carried out that ${\alpha}-glycoside$ linkage of maltitol was not hydrolyzed with pancreatic enzymes and intestinal mucosa. Maltitol dehydrogenase was not obeserved in liver cytoplasm, and hepbtic sorbitol dehydrogenase was not induced by maltitol administsation. Also, the effect of maltitol on aging of aluminum hydroxide gel, prepared by the reaction of aluminum chloride solution with strong ammonia solution to final pH 7.0, was studied by potentiometric titration, pH and acid-consuming capacity. Gel containing 1% or 2% maltitol was lost less than 2% of their acid-consuming capacity during a 120 days aging period compared with a loss of more than for an identical gel without maltitol and gel containing 0.5% maltitol.
