摘要:
Disclosed are a novel desiccant containing a non-reducing anhydrous trehalose as an effective ingredient; a dehydration of hydrous matters, e.g. food products, pharmaceuticals and cosmetics, therewith; and dehydrated products obtained by the dehydration. Such hydrous matters are dehydrated without causing alteration or deterioration by incorporating anhydrous trehalose into the hydrous matters to convert the anhydrous trehalose into hydrous crystalline trehalose. The anhydrous trehalose are anhydrous crystalline trehalose and hydrous amorphous trehalose.
摘要:
Novel non-reducing oligosaccharide having a structure represented by the formula of alpha-D-oligoglucosyl alpha-D-oligoglucoside is obtained by exposing either an aqueous solution which contains trehalose and an alpha-glucosyl saccharide or an aqueous solution which contains a non-reducing saccharide bearing a trehalose structure at its end to a saccharide-transferring enzyme. The oligosaccharide has a reduced sweetness, superior stability, appropriate viscosity and less or no susceptibility to crystallization or superior solubility when in crystalline form. These features make the oligosaccharide very useful in various compositions including foods, beverages, cosmetics, pharmaceuticals and shaped bodies.
摘要:
In the production of non-reducing saccharides such as trehalose, alpha-glycosyl trehaloses and alpha-glycosyl alpha-glycosides where a solution of liquefied starch is subjected either to non-reducing saccharide-forming enzyme or non-reducing saccharide-forming enzyme and trehalose-releasing enzyme, combinations with starch-debranching enzyme and/or cyclomaltodextrin glucanotransferase improve the yields for such non-reducing saccharides to levels which are hardly attainable only with reducing-saccharide-forming enzyme and trehalose-releasing enzyme. The non-reducing saccharides and less reducing reducing saccharides containing the same commonly bear a variety of desirable properties which make them useful in a variety of compositions including food products, cosmetics and medicines.

摘要:
Novel crystalline maltotetraosyl glucoside is obtained by crystallizing maltotetraosyl glucoside from a solution of maltotetraosyl glucoside, prepared by either exposing an aqueous solution of maltopentaose to the action of a non-reducing saccharide-forming enzyme or an aqueous solution which contains trehalose or a non-reducing saccharide to the action of cyclomaltodextrin glucanotransferase. The crystalline maltotetraosyl glucoside has non-hygroscopicity, non-reducibility, superior solubility, less fermentability, and other satisfactory properties of stabilizing oligopeptides and biologically-substances as well as preventing retrogradation of amylaceous substances. These features render the crystalline maltotetraosyl glucoside very useful in various compositions including foods, beverages, cosmetics, pharmaceuticals and shaped bodies.

摘要:
The object of the present invention is to provide a powdery product comprising crystalline β-maltose monohydrate which is powderized by spray method, and has a high-solubility in aqueous solvents and a satisfactory handleability, and to its preparation and uses. The present invention solves the above object by establishing a powdery product comprising crystalline β-maltose monohydrate which comprises 7% (w/w) or more but less than 14% (w/w) (x-anomeric maltose, and has a crystallinity of 62% or more but less than 72%; a process for producing thereof which comprises the steps of producing a massecuite from an aqueous maltose solution comprising 86% (w/w) or more but less than 93% (w/w) of maltose and 2% (w/w) or more of glucose, on a dry solid basis, powderizing by a spray method, keeping in a relatively low humidity and a relatively high temperature, and further keeping in a relatively high humidity- and a relatively low temperature-condition; and uses thereof for various compositions such as foods, cosmetics, and pharmaceuticals.

Novel crystalline maltosyl glucoside is obtained by crystallizing maltosyl glucoside from a maltosyl glucoside solution, prepared by exposing either an aqueous solution containing trehalose and an .alpha.-glucosyl saccharide or an aqueous solution containing a reducing partial starch hydrolysate to the action of a saccharide-transferring enzyme. The crystalline maltosyl glucoside has non-hygroscopicity, non-reducibility, superior solubility, less fermentability, and other properties of stabilizing oligopeptides and biologically-substances as well as preventing retrogradation of amylaceous substances. These features render it very useful in various compositions including foods, beverages, cosmetics, pharmaceuticals and shaped bodies.

Disclosed is a novel non-reducing oligosaccharide with neotrehalose structure represented by the general formula as shown by: ##STR1## The oligosaccharide is obtainable by exposing an aqueous solution containing neotrehalose to a saccharide-transferring enzyme, and has a superior stability, reduced sweetness, appropriate viscosity, no susceptibility to crystallization and less fermentability. These features make it very useful in various compositions including foods, beverages, cosmetics and pharmaceuticals.
