摘要: Novel aldehyde-functionalized polysaccharide compositions containing pendant dialdehyde groups are described that are more stable in aqueous solution than oxidized polysaccharides. The aldehyde-functionalized polysaccharides may be reacted with various amine-containing polymers to form hydrogel tissue adhesives and sealants that may be useful for medical applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures such as intestinal anastomosis and vascular anastomosis, tissue repair, preventing leakage of fluids such as blood, bile, gastrointestinal fluid and cerebrospinal fluid, ophthalmic procedures, drug delivery, and preventing post-surgical adhesions.

摘要: The invention relates to a process for the production of a fructooligosaccharide (FOS) composition on industrial scale, comprising the steps of: a) providing a raw material containing sucrose; b) bringing the raw material together with an enzyme to form a mixture, whereby the enzyme has an endo-inulinase activity and/or a fructosyltransferase activity and is in free, non-immobilized form; c) exposing the mixture to conditions whereby FOS-forming can take place for an amount of time such that the FOS in the mixture constitutes at least 45 wt. % of the total amount of carbohydrates in the mixture, thereby forming the FOS composition; d) optionally deactivating the enzyme; e) recovering the FOS composition. The invention further relates to Fructooligosaccharide composition (FC) wherein: a portion of at most 2 wt. % of the carbohydrates in the FC consists of oligosaccharides that have a degree of polymerisation (DP) of 7 or more; and at least 56 wt. % of the fructooligosaccharides in the FC have a DP of 3 as measured in HPLC; and the FC is obtained from sucrose in an enzymatic process, whereby no enzyme is used that is obtained from a genetically-modified organism.
