  • Publication number: 20060165674
    Abstract: The present invention intends to provide a granular composition which is stable at high temperature and high humidity and to provide a simple method of efficiently producing such a granular composition. According to the present invention, there is provided a granular composition containing a core material and a layer that covers the core material, in which the core material is made of saccharides and the layer that covers the core material contains a bioactive ingredient and a hardened oil. In addition, there is provided a method of producing the granular composition, including allowing a mixture of a molten hardened oil and a bioactive ingredient to adhere to a granular saccharide or to be formed into a film thereon.
