摘要:
Problem: To develop a method for producing a novel sweetener containing glucose, fructose, and psicose, which is produced from glucose liquid sugar using an isomerase and an epimerase; use of the novel sweetener as a food or drink material; and a novel sweetener capable of preventing obesity caused by the intake thereof. Means of Resolution: An isomerase and an epimerase are allowed to act on glucose liquid sugar produced in a glucose liquid sugar production plant to thereby produce D-psicose, thereby providing a novel sweetener (product) that maintains the degree and quality of sweetness of a glucose-fructose mixed solution and never causes obesity, a method for producing the same, and use of the same.
摘要:
Disclosed is a process for producing a crystalline sugar comprising D-psicose and D-allose. Also disclosed is a process for producing the sugar. A complex crystalline sugar comprising D-psicose and D-allose. The compositional ratio between D-psicose and D-allose in the sugar is about 1:1 to 1:4. A process for producing a complex crystalline sugar comprising D-psicose and D-allose, the process comprising producing a complex crystalline sugar comprising D-psicose and D-allose from a sugar solution containing D-psicose and p-allose and collecting the complex crystalline sugar. The solvent of the sugar solution used in the production of the complex crystalline sugar is water or a mixture of water and ethanol. The sugar solution containing D-psicose and D-allose is produced by a process comprising reacting D-psicose with L-rhamnose isomerase to convert D-psicose into D-allose. The L-rhamnose isomerase is derived from a strain (IPOD FERM BP-08593) belonging to Pseudomonas stutzeri.
摘要:
Screening for a glucokinase-activating substance among rare sugars and providing a composition for treating disordered conditions in association with glucokinase activity, the composition containing the glucokinase-activating substance as the active ingredient. A promoting agent of glucokinase transfer from nucleus to cytoplasm, the promoting agent containing D-psicose and/or D-tagatose as the active ingredient, or a composition for preventing the onset of disordered conditions in association with glucokinase activity or for therapeutically treating the disordered conditions, which is in a form selected from a group consisting of food additives, food materials, drinks and foods, health drinks and foods, pharmaceutical product and feeds in blend with D-psicose and/or D-tagatose as the active ingredient for use in preventing the onset of disordered conditions in association with glucokinase activity or for therapeutically treating the disordered conditions. The disordered conditions in association with glucokinase activity are selected from impaired glucose tolerance, type 2 diabetes mellitus, insulin resistance, abnormal lipidemia, the metabolic syndrome and obesity. The composition is in a pharmaceutical form, and contains D-psicose and/or D-tagatose together with one or more pharmaceutically acceptable carriers.
