摘要:
A process for the preparation of long-chain inulin having an average chain length greater than 20 monomer units while simultaneously obtaining glucose and fructose is performed. An aqueous crude inulin suspension with a crude inulin concentration of 20-70% by weight is subjected to enzymatic treatment with inulinase at temperatures of 30.degree.-70.degree. C. During the process the short-chain components are degraded to mono- and disaccharides, and the long-chain inulins are then separated off from the mono- and disaccharides and converted into dry form. The long chain inulins may be separated from the mono- and disaccharides by crystallization by cooling and centrifugation or chromatographically using a strongly acidic cation exchange resin loaded with calcium ions. The long chain inulins can be used as a component in foodstuffs, in conjunction with sweeteners, bulking agents, thickeners, stabilizers, as well as a fat substitute in foodstuffs, a carbohydrate substitute, dietary fiber, as an excipient for pharmacologically active substances, and as an indicator for kidney clearance.

摘要:
This invention concerns a method for enzymatic preparation of 6-O-α-D-glucopyranosyl-D-sorbitol (1,6-GPS) from isomaltulose. It is specified that the isomaltulose is put into an aqueous reaction solution containing a unit having sorbitol dehydrogenase (SDH) activity, incubated, and then 1,6-GPS is recovered from the reaction solution.
摘要:
The invention relates to a process for producing mixtures selectively enriched with either 1,1-GPM and 1,6-GPS from hydrogenated isomaltulose. The process involves dissolving hydrogenated isomaltulose at an elevated temperature, and subjecting the resulting solution to one or more cooling steps, wherein each cooling step utilizes a predetermined cooling rate over a predetermined temperature range.
