Methods for the production of pectin hydrolysis products, the pectin hydrolysis products produced in this manner, as well as their use are described.

Method for producing pectin hydrolysis products

The present invention relates to methods for the production of pectin hydrolysis products, the pectin hydrolysis products produced in this manner, as well as their use.

The invention relates to the use of the disaccharide derivatives 3'-aminosucrose, sucrose-C6-acid and palatinose-C6&#x2032;-acid and/or of an amide or alkyl ester thereof for the prevention or treatment of hyperglycemias.

Disaccharide derivatives for treating hyperglycaemia

The invention relates to the use of the disaccharide derivatives 3&prime;-aminosucrose, sucrose-C6-acid and palatinose-C6&prime;-acid and/or of an amide or alkyl ester thereof for the prevention or treatment of hyperglycemias.

A low-calorie, non-cariogenic sweetener suitable for diabetics comprising (fructosyl).sub.n mannitol and/or (fructosyl).sub.n sorbitol, where n=1-6, or a mixture of these compounds, and a process for the preparation thereof by hydrogenation of homooligomeric fructooligosaccharides.

Hydrogenated fructooligosaccharides

A process for the preparation of a sweetener, in which sucrose is converted enzymatically into a saccharide mixture which is called 'isomerized sucrose' and has a disaccharide content of more than 85% by weight, then non-isomerized remaining sucrose is removed from the latter by enzymatic and/or H.sup.+ ion-catalyzed cleavage, and this product is catalytically hydrogenated. Preferably either before or after the catalytic hydrogenation, the resulting mixture is subjected to a chromatographic separation. The sweeteners prepared by this process contain either a mixture of 10 to 50% by weight of 6-O-.alpha.-D-glucopyranosyl-D-sorbitol; 2 to 20% by weight of 1-O-.alpha.-D-glucopyranosyl-D-sorbitol; and 30 to 70% by weight of 1-O-.alpha.-D-glucopyranosyl-D-mannitol or of 5 to 10% by weight of 6-O-.alpha.-D-glucopyranosyl-D-sorbitol; 30 to 40% by weight of 1-O-.alpha.-D-glucopyranosyl-D-sorbitol; and 45 to 60% by weight of 1-O-.alpha.-D-glucopyranosyl-D-mannitol.

Sweetener, process for its preparation and the use thereof

The invention relates to a method for the preparation of rhamnose from rhamnolipids, for which an acidic emulsion of the rhamnolipid is hydrolyzed at 100.degree. to 200.degree. and subsequently cooled, the aqueous phase of the resulting hydrolysate is separated from the lipid phase, its pH is raised by the addition of a basic compound, any precipitate formed is removed, the remaining solution is concentrated and either processed further directly or chromatographed on ion exchange resin, rhamnose-containing fractions being obtained as eluate, which are processed further as such or worked up into crystalline rhamnose monohydrate.

Method for the preparation of rhamnose monohydrate from rhamnolipids

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.
