    摘要: In the invention, highly pure crystals of difructose dianhydride III (di-D-fructofuranose-1,2′:2,3′-dianhydride; hereinafter referred to as DFA III) are produced by adding 5% or less of powdered active carbon to a DFA III containing purified solution containing DFA III of 90% or more purity at a concentration of R-Bx 10-60, preferably 40-55, and after stirring, applying the mixture to solid-liquid separation (filtration with diatomaceous, filtration through a membrane filter, ultrafiltration, or continuous centrifugal separation) and concentrating the separated liquid part, followed by immediate crystallization.In the process of the invention, DFA III crystals can be produced efficiently and industrially, and the resulting crystals can be used for various purposes in pharmaceuticals or food and drink since they have no smell. This is characteristics of the invention different from the prior art products.

    摘要: 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.
