Abstract
Disclosed herein is a sphingan oligosaccharide composition, its uses, and a process for preparing the same.
Claims20
A process for preparing a sphingan oligosaccharide composition, comprising:
- (a) providing a sphingan composition comprising a sphingan and a liquid medium comprising a water;
- (b) contacting the sphingan composition with an effective amount of a solid acid to obtain an exchanged solid acid and an acidified sphingan composition;
- (c1) separating the acidified sphingan composition from the exchanged solid acid and hydrolyzing the acidified sphingan composition in the absence of the exchanged solid acid to obtain a sphingan hydrolysate composition;
- or
- (c2) hydrolyzing the acidified sphingan composition in the presence of the exchanged solid acid to obtain a sphingan hydrolysate composition and separating the exchanged solid acid from the sphingan hydrolysate composition;
- (d) adding a base to the sphingan hydrolysate composition to obtain the sphingan oligosaccharide composition having a pH of about 4 to about 8;
- and
- (e) optionally, contacting the sphingan composition and/or the sphingan oligosaccharide composition with a solid base.
5 more elements
A composition comprising:
- a sphingan oligosaccharide composition having a residual salt content of not more than about 5% by weight of the composition.
