Abstract: The invention relates to polysaccharide derivatives consisting of a biopolysaccharide skeleton and organic groups with a molecular weight <5 000 that are connected to said skeleton via ether bridges. The organic groups have the general formula (Ia) or (Ib). Preferably, ?- or ?-(1,4)- and/or ? or ?-(1,3)-glucan units are used as the biopolysaccharide component, such as e.g. xy-loglucans, glucomannans such as guar gum or locust bean gum, xanthan gum, carrageenans, alginates and pectins. The invention also relates to a method for producing said polysaccharide derivatives, according to which the biopolysaccharide component is reacted with an N-alkyl maleamic acid or a salt thereof in the presence of a base catalyst, whereby the maleamide component can also be cyclised prior to or following the reaction with the biopolysaccharide component.

Abstract: The present invention relates to the use of distillers grains fermented with a yogurt culture and/or buttermaking culture for producing a composition for preventing and/or treating increased blood sugar values.

Abstract: The claimed method for preparing conjugated polyunsaturated fatty acid esters consisting of an alcohol radical R1 having from 1 to 5 carbon atoms and a fatty acid radical R2 having from 10 to 24 carbon atoms, together with alkoxides having from 1 to 5 carbon atoms, comprises carrying out the reaction solvent-free using a phase-transfer catalyst. In this method, the contents of the fatty acid ester should be from 85 to 99.9% by weight, those of the alkoxide component from 0.05 to 10% by weight, and those of the phase-transfer catalyst from 0.05 to 5.0% by weight, in each case based on the total reaction mixture. Esters of linoleic acid and linolenic acid are preferred as starting material, just as sodium or potassium methoxide or sodium or potassium ethoxide are preferred as alkoxide. Suitable phase-transfer catalysts are, for example, polyethylene glycols, polyethylene glycol monomethyl ethers or polyethylene glycol dimethyl ethers, crown ethers and quaternary ammonium or phosphonium salts.

Abstract: The invention relates to a method for the production of phospholipids of general formula (I) with the exclusive aid of phospholipase D from a phospholipid mixture and without using organic solvents, wherein phosphatidyl acid is produced in an aqueous, unbuffered phase with phospholipase D and at least one bivalent metal ion in a first step and at least one phospholipid of general formula (I) is produced from the phosphatidyl acid having at least one compound of general formula (II) R3—OH in a second step. Phosphatidylserine, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinosite and/or phosphatidylglycerine are obtained as products. In another embodiment of the invention, the PLD is identical or different in both steps of said method, wherein in the latter case the pH values for the first and second steps of the method are different, said values lying particularly between 6.5 and 8.0, especially between 5.0 and 7.5.
