Effects of Lactitol-Oligosaccharides on Calcium and Magnesium Absorption in Rats.

Abstract

SummaryLactitol-oligosaccharide (LO) was prepared from lactitol by transglycosylation reaction with Aspergillus oryzae ƒÀ-galactosidase.

Absorptive Activity of Calcium in the Isolated Cecal Epithelium Adaptively Increased by 2 Week's Feeding of Difructose Anhydride III in Rats

“…In balance studies in vivo, a positive correlation exists between apparent Ca absorption and total SCFA, acetic, propionic or butyric acid concentration in the cecum of rats. 11,12) Other factors caused by the fermentation process might be involved in this functional change in the large intestine. Enlargement of the cecum and the colon induced by fermentation products extends the absorptive area and contributes to an increase in Ca absorption.…”

α-d-Glcp-(1↔1)-β-d-Galp-containing oligosaccharides, novel products from lactose by the action of β-galactosidase

“…Several studies suggest that the volatile fatty acids resulting from the fermentation of galacto-oligosaccharides by the intestinal microflora improve the absorption ability of the intestinal epithelium [2][3][4].…”

Synthesis of Galactosyl Mannitol Derivative Using β-Galactosidase from Kluyveromyces lactis

“…Lu et al [2009] used an enzyme from Enterobacter cloacae for gal-sorbitol synthesis. Moreover, the following compounds were also used as acceptors: erythritol [Irazoqui et al, 2009;Klewicki, 2007a], maltitol (using cyclodextrin glucanotransferase) [Kim et al, 1997] and lactitol [Klewicki, 2007a;Yanahira et al, 1997]. The possibility of attaching a galactosyl residue (as well as other saccharides) to an acceptor other than sorbitol, provides conditions for obtaining gal-polyols with properties potentially different than these of lactitol.…”
