PRODUCTION OF AGENT FOR IMPROVING FLAVOR OF BEVERAGE OR FOOD

摘要

PURPOSE:To obtain the subject flavor-improving agent containing triose reductone and useful for general purposes by subjecting glucose in a heated glucose aqueous solution to the alkali decomposition reaction in the presence of a specific amount of sodium hydroxide an subsequently adjusting the pH of the reaction solution. CONSTITUTION:Ion exchange water and anhydrous D-glucose are added into a flask and subsequently heated and stirred under the flow of an ordinary pressure nitrogen gas at 87-89 deg.C, and the produced glucose homogeneous solution is mixed with a sodium hydroxide aqueous solution containing sodium hydroxide in an amount of 0.9-1.4 moles based on the glucose and subjected to an alkali decomposition reaction for 0.5-3min. The decomposition reaction solution is immediately cooled to <=20 deg.C to obtain the decomposition solution containing triose reductone in a concentration of >=1.5g/1000. The decomposition reaction solution is mixed with concentrated hydrochloric acid to adjust the pH of the reaction solution to 5-7, thus providing the objective flavor-improving agent for beverages and foods and useful for general purposes.
