Patent number: 7754701Abstract: The present invention relates to a difructose anhydride (DFA)-containing composition and use thereof. DFA is a cyclic disaccharide in which the reducing termini of two fructose molecules bind each other to hydroxyl groups at the other nonreducing termini. According to the present invention, it has been revealed that DFA is effective in accelerating the absorption of magnesium, zinc or copper, accelerating bone formation, accelerating diuretic action, and improving bowel movement and is useful in inhibiting dental caries. A composition of the present invention can be used as a composition for a medicinal product and a food or drink product (including feed for animal use). Examples of a medicinal product and a food or drink product for human or animal use include formulated powder milk, parenteral nutrients, health food and drink products, and additives for feed and are not particularly limited as long as they are ultimately in an orally administrable form.Type: GrantFiled: April 24, 2003Date of Patent: July 13, 2010Assignees: Fancl Corporation, Nippon Beet Sugar Manufacturing Co., Ltd.Inventors: Takuya Shiomi, Yasuhide Okuhara, Akiko Tamura, Kyoko Tomita, Norihiro Shigematsu, Hiroto Kikuchi, Tsutomu Aritsuka, Fusao Tomita
