The present invention has objects to provide a glucan useful as water-soluble dietary fiber, its preparation and uses. The present invention solves the above objects by providing a branched &#x3b1;-glucan, which is constructed by glucose molecules and characterized by methylation analysis as follows:

Branched alpha-glucan, alpha-glucosyltransferase which forms the glucan, their preparation and uses

Branched &#x3b1;-glucan, &#x3b1;-glucosyltransferase which forms the glucan, their preparation and uses

The objects of the present invention are to provide a method for inhibiting the coloration of a syrupy sweetener, comprising a reducing saccharide together with a non-reducing oligosaccharide having a &#x3b2;-fructofuranosidic linkage, without deteriorating the taste inherent to the syrupy sweetener; and to provide a syrupy sweetener, comprising a reducing saccharide together with a non-reducing oligosaccharide having a &#x3b2;-fructofuranosidic linkage, which is stabilized by the method. The present invention attains the above objects by providing a method for inhibiting the coloring of a syrupy sweetener, comprising a reducing saccharide together with a non-reducing oligosaccharide having a &#x3b2;-fructofuranosidic linkage, which comprises a step of incorporating a lactate into the syrupy sweetener, and by providing a syrupy sweetener, comprising a reducing saccharide together with a non-reducing oligosaccharide having a &#x3b2;-fructofuranosidic linkage, which is stabilized by the method.

Method for inhibiting coloring of a syrupy sweetener comprising a non-reducing oligosaccharide having a beta-fructofranosidic linkage and a reducing saccharide, and use thereof

The present invention has objects to provide a thermostable cellobiose 2-epimerase, its preparation and uses. The present invention attains the above objects by providing a thermostable cellobiose 2-epimerase, a DNA encoding the enzyme, a recombinant DNA and transformant comprising the DNA, a process for producing the enzyme, and a process for producing isomerized saccharides using the enzyme.

Cellobiose 2-epimerase, its preparation and uses

An object of the present invention is to provide a novel starchy substance having a retrogradation-resistance, a process for producing the starchy substance efficiently from a material starch by enzymatic reaction, and uses thereof. The present invention attains the above object by providing branched starch having 6-&#x3b1;-maltosyl- and/or 6-&#x3b1;-maltotetraosyl-structure(s) with a marked retrogradation-resistance, a process for producing the branched starch without lowering the molecular weight of material starch, and uses thereof.

Highly-branched starch, its production and uses

The object of the present invention is to establish a volatile sulfide production inhibitor that can inhibit the production of volatile sulfides from a composition and to provide a method for inhibiting the production of volatile sulfides from a composition by using the inhibitor. The object are solved by providing a volatile sulfide production inhibitor comprising L-ascorbic acid 2-glucoside as an effective ingredient and a method for inhibiting the production of volatile sulfides from a composition by incorporating the volatile sulfide production inhibitor into the composition.

Volatile sulfide production inhibitor and method for inhibiting the production of volatile sulfide using the inhibitor

An object of the present invention is to provide a novel ketose 3-epimerase, a process for producing the same, a DNA encoding the enzyme, a recombinant DNA and transformant comprising the DNA, and a process for producing a ketose by using the enzyme. The present invention solves the above objects by providing a ketose 3-epimerase which is obtainable from a microorganism of the genus, a process for producing the same, a DNA encoding the enzyme, a recombinant DNA and transformant comprising the DNA, and a process for converting D- or L-ketohexose into corresponding D- or L-ketohexose by epimerizing the hydroxyl group at the C-3 position of the D- or L-ketohexose; and D- or L-ketopentose into corresponding D- or L-ketopentose by epimerizing the hydroxyl group at the C-3 position of the D- or L-ketopentose; by using the enzyme.

Ketose 3-epimerase, its preparation and uses

An object of the present invention is to provide an immunomodulating agent in gut that can be ingested continuously in daily diet without adverse side effect. The object is attained by providing an immunomodulating agent in gut comprising a cyclic tetrasaccharide as an effective ingredient.

Immunomodulating agent in gut

A process for producing rice flour, which comprises the steps of soaking material rice grains in water, crushing the resulting rice grains, penetrating &#x3b1;,&#x3b1;-trehalose or maltitol into the rice grains, partially drying the resulting rice grains, and milling the partially dried rice grains; rice flours obtainable by the process; and uses thereof for producing bakery products and noodles.

Process for producing rice flour and use thereof

A polypeptide having &bgr;-fructofuranosidase activity is obtained by the expression of a microbial gene, which polypeptide contains the amino acid sequences of SEQ ID NO:1 and SEQ ID NO:2 in whole or in part as an amino acid sequence. This polypeptide is useful for producing fructofuranosyl transferred saccharides.
