Saccharide polycondensate, method for producing the same, and application therefor

Abstract

An object of the present invention is to provide a method for producing a saccharide polycondensate which is inexpensive and is applicable to a food or beverage product. Disclosed is a method for producing a saccharide polycondensate, which comprises carrying out a saccharide polycondensation reaction in the presence of activated carbon.

1 . A method for producing a saccharide polycondensate or a reduced product thereof, which comprises polycondensing one or more saccharides or derivatives thereof in the presence of activated carbon. 
     
     
         2 . The method according to  claim 1 , wherein the saccharide is selected from a monosaccharide, an oligosaccharide, and a polysaccharide. 
     
     
         3 . The method according to  claim 1 , wherein a polycondensation reaction is carried out under normal or reduced pressure. 
     
     
         4 . The method according to  claim 1 , wherein the polycondensation reaction is carried out under a temperature of 100° C. to 300° C. 
     
     
         5 . The method according to  claim 1 , wherein a saccharide polycondensate or a reduced product thereof is produced as a saccharide polycondensate composition. 
     
     
         6 . The method according to  claim 5 , wherein the content of a dietary fiber in the saccharide polycondensate composition is 30% by weight or more. 
     
     
         7 . A saccharide polycondensate or a reduced product thereof, or a saccharide polycondensate composition, which is produced by the method according to  claims 1 . 
     
     
         8 . A food or beverage product, which is obtained by adding thereto the saccharide polycondensate or the reduced product thereof, or a saccharide polycondensate composition according to  claim 7 . 
     
     
         9 . The food or beverage product according to  claim 8 , which further comprises a high intensity sweetener. 
     
     
         10 . The food or beverage product according to  claim 9 , which is a beverage. 
     
     
         11 . The food or beverage product according to  claim 10 , wherein the beverage is a carbonated beverage, an isotonic sport beverage, a beverage containing fruit juice, a coffee beverage, or an alcoholic beverage. 
     
     
         12 . The food or beverage product according to  claim 9 , wherein the content of a saccharide polycondensate and a reduced product in the food or beverage product is 0.02% to 20% by weight. 
     
     
         13 . The food or beverage product according to  claim 8 , which is a beer-flavored beverage. 
     
     
         14 . The food or beverage product according to  claim 13 , wherein a saccharide polycondensate or a reduced product thereof, or a saccharide polycondensate composition is added before fermentation and/or during fermentation. 
     
     
         15 . The food or beverage product according to  claim 13 , wherein a saccharide polycondensate or a reduced product thereof, or a saccharide polycondensate composition is added after fermentation. 
     
     
         16 . The food or beverage product according to  claim 13 , wherein the content of a saccharide polycondensate and a reduced product in the food or beverage product is 0.1% to 10% by weight. 
     
     
         17 . A method for producing a beer-flavored alcoholic beverage, which comprises adding the saccharide polycondensate or the reduced product thereof or the saccharide polycondensate composition according to  claim 7  to a wort or an unfermented liquid to carry out fermentation. 
     
     
         18 . A method for producing a beer flavored alcoholic beverage, which comprises adding the saccharide polycondensate or the reduced product thereof, or the saccharide polycondensate composition according to  claim 7  to a fermented liquid. 
     
     
         19 . A livestock feed, which is obtained by adding thereto the saccharide polycondensate or the reduced product thereof, or the saccharide polycondensate composition according to  claim 7 .
