Abstract

A novel dehydration method using anhydrous glycosylfructose as the desiccant is disclosed. Anhydrous glycosylfructose is converted to the crystalline hydrate and acts as the desiccant when incorporated into a hydrous matter. Natural saccharides such as palatinose, raffinose, erlose, and melezitose can be used. The dehydration is applicable to hydrous matters, such as those of foods, pharmaceuticals, cosmetics, and their materials and intermediates.

Claims

1. A method for dehydrating a hydrous product, comprising incorporating an anhydrous glycosylfructose into the hydrous product to convert said anhydrous glycosylfructose into crystalline glycosylfructose hydrate.

2. The method of claim 1, wherein said anhydrous glycosylfructose is a high-purity glycosylfructose having a glycosylfructose content of 90% or higher, based on the dry solid.

3. The method of claim 1, wherein said anhydrous glycosylfructose is in pulverulent form.

4. The method of claim 1, wherein the moisture content of said anhydrous glycosylfructose is lower than 3 w/w %

5. The method of claim 1, wherein 0.01 to 500 parts by weight of an anhydrous glycosylfructose is incorporated into one part by weight of a hydrous product.

6. The method of claim 1, wherein the glycosylfructose is a member selected from the group consisting of palatinose, raffinose, erlose, melezitose, and mixtures thereof.

7. The method of claim 1, wherein said hydrous product is a member selected from the group consisting of food products, pharmaceuticals, cosmetics, and materials and intermediates thereof.

8. The method of claim 1, wherein said hydrous product contains a member selected from the group consisting of gelatinized starch, alcohol, oil-soluble substance and bioactive substance.
