Estimating the term…
A physiologically active substance of aglycon type, in particular, aglycon isoflavone, can be efficiently produced, without resort to any acid/alkali treatment or fermentation and substantially without changing the physical properties of a material, by treating the material with a sufficient amount of diglycosidase for a sufficient period of time at an appropriate temperature and pH so that a physiologically active substance of glycoside type contained in the material can be converted into the physiologically active substance of aglycon type. Moreover, by using diglycosidase and/or a specific enzyme preparation, the aglycon content in a protein or protein-containing food can be increased and the flavor thereof can be improved.
A process for producing a protein having an increased aglycon content or a food containing the protein, which comprises a step of treating a protein or protein-containing food with diglycosidase, wherein said diglycosidase has activity to act upon a disaccharide glycoside to release saccharides in a disaccharide unit.
A process for producing a flavor-improved protein or a food containing the protein, which comprises a step of treating a protein or protein containing food with a diglycosidase and an enzyme preparation containing mainly at least one enzyme selected from the group consisting of amylases, cellulases, pectinases, proteases, lipases, β-glucosidases, β-galactosidases, and yeast-dissolving enzymes, wherein said diglycosidase has activity to act upon a disaccharide glycoside to release an aglycon and saccharides in a disaccharide unit.
A method of administering diglycosidase orally to form an aglycon from a glycoside in a living body, wherein said diglycosidase has activity to act upon a disaccharide glycoside to release saccharides in a disaccharide unit.
A method of accelerating a bioabsorption of a physiologically active substance, which comprises administering diglycosidase orally before, during, or after the ingestion of a food containing a physiologically active substance of glycoside type, wherein said diglycosidase has activity to act upon a disaccharide glycoside to release saccharides in a disaccharide unit.
An agent for converting a physiologically active substance of glycoside type into the physiologically active substance of aglycon type, which contains at least a diglycosidase, wherein said diglycosidase has activity to act upon a disaccharide glycoside to release saccharides in a disaccharide unit.
