Abstract: A granulating method is a method in which powder containing a water-soluble component is granulated. In the disclosed granulating method, a dispersion element, wherein fine water droplets are dispersed in superheated steam, is expelled from a nozzle, and thus the dispersion element and powder in a flowing state come into contact with one another. It is preferable that the mass ratio of superheated steam contained in the dispersion element, as a mass ratio found from the theoretical flow amount of superheated steam expelled from the nozzle, and the actual flow amount of water supplied to the nozzle, be set in a range of 20-70 mass %.

Abstract: An antioxidant material of the present invention contains flavonoid aglycon and vitamin C. The flavonoid aglycon is eriodictyol and/or diosmetin obtained by treatment of a raw material containing flavonoid glycoside derived from lemons, limes, or sudachis to form the aglycones thereof. It is preferred that this antioxidant material be produced through a step of mixing the flavonoid aglycon and the vitamin C after the treatment to form the aglycones. The treatment to form the aglycones is glycosidase treatment using a ?-glycosidase derived from a microorganism of the genus Aspergillus or Penicillium multicolor, or microbial fermentative treatment using a microorganism of the genus Aspergillus. An anti-deterioration agent and a food or beverage of the present invention contain the antioxidant material.

Abstract: Volatile components are obtained by steam extraction of tasty materials. Coffee beans following roasting or tea leaves following tea manufacturing are used as tasty materials. Steam extraction includes of processing in which steam is contacted with a tasty material followed by recovery of the steam after that contact. Saturated water vapor or super heated steam is used for the steam, while super heated steam is used preferably. The coffee beans are preferably those that have been obtained by roasting raw coffee beans using super heated steam. The food or drink contains the aromatic components, and preferably contains the volatile components as well as an aqueous extract of the tasty material.
