Abstract: The present invention relates to a process for reducing the acrylamide content of heat-treated foods compared with corresponding conventional heat-treated foods.

Abstract: Nucleic acid molecules which encode a branching enzyme from a bacterium of the genus Neisseria, vectors, host cell, plant cells and plants containing said nucleic acid molecules as well as starch obtainable from the plants described are described. Furthermore, an in-vitro method for producing &agr;-1,6-branched &agr;-1,4-glucans on the basis of sucrose and a combination of enzymes of an amylosucrase and a branching enzyme as well as the &agr;-1,6-branched &agr;-1,4-glucans obtainable by said method are described.

Abstract: The invention relates to a production method of &agr;-amylase resistant polysaccharides with high RS content, comprising the following steps: a) producing a paste of water-insoluble poly-(1,4-&agr;-D-glucan) and water; b) heating the paste; c) cooling off and retrogradation of the past at a temperature that is lower than the temperature of the heated paste and d) optionally drying the resulting product.

Abstract: The invention relates to a method for producing polysaccharides containing &agr;-1,4-glucan chains. According to the inventive method, a glucosyl group acceptor undergoes a chain prolongation reaction by reacting it with saccharose in the presence of an amylosaccharase. The amount of the glucosyl group acceptor in the reaction mixture is chosen in such a way that the mole ratio of the available ends of the glucosyl group acceptor to the saccharose is at least 1:1,000 and/or the weight ratio of the glucosyl group acceptor to the saccharose is at least 1:0.

Abstract: Nucleic acid molecules encoding an alternansucrase are provided. Moreover, vectors, host cells and plant cells transformed by the herein-described nucleic acid molecules and plants containing them are provided. Furthermore, methods are described for preparing transgenic plants which synthesize the carbohydrate alternan, because of the insertion of nucleic acid molecules encoding an alternansucrase. Moreover, methods for preparing alternan and products resulting from them are provided.

Abstract: Transgenic plant cells and plants with an increased activity of an amylosucrase protein and an increased activity of a branching enzyme are provided. Such plant cells and plants synthesize a modified starch and/or synthesize &agr;-1,6 branched &agr;-1,4-glucans with a modified branching degree in O-6-position and/or give a higher yield in comparison with corresponding genetically non-modified wild type plants (plant cells).
