A water-soluble dietary fiber comprising as a main component a partially hydrolyzed product of a hemicellulose extracted from a vegetable fiber material by an alkali treatment and subjected to enzymolysis. Various kinds of food and drink can be prepared by mixture of this dietary fiber. Also disclosed is a method of preparing a water-soluble dietary fiber, comprising the steps of subjecting a vegetable fiber material to extraction by an alkali treatment, and treating an extract therefrom with a xylanase to give a partially hydrolyzed product of hemicellulose.

A method for recovering cyclodextrin, comprising passing an aqueous solution containing an inclusion compound of cyclodextrin with a guest compound, through a non-polar, high-porous hydrophobic adsorption resin, which is the cross-linked copolymer of styrene with divinylbenzene, comprised of styrene as a basic skeleton, to cause the adsorption resin to preferentially adsorb the guest compound for its removal. The method enables economical recovery of cyclodextrin in a good efficiency and at a high purity from inclusion compounds of cyclodextrin with guest compounds such as cholesterol and other lipids.

The present invention relates to a novel process for recovering cyclodextrins, characterized in that a solution containing cyclodextrins as well as starches, dextrins, reducing sugars and the like is brought into contact with a hydrophobic, synthetic adsorption resin comprising a porous polymer to adsorb only cyclodextrins, the cyclodextrins thus adsorbed being eluted thereafter with water while being heated to separate and recover said cyclodextrins.

A process for the production of oil from oil sand includes adding cyclodextrin or a starch decomposition product containing cyclodextrin to oil sand to convert petroleum in the oil sand to an inclusion compound and separating and collecting petroleum alone from the inclusion compound.

Process for production of oil from oil sand

This invention provides a novel process for producing cyclodextrin by reacting cyclodextrin glycosyl transferase having an optimum pH on the alkaline side with gelatinized starch. According to this invention, cyclodextrin can be obtained in the form of a pure crystal in a high yield by reacting a glucomylase with the reaction mixture liquid formed by the above enzymatic reaction to decompose unreacted starch, concentrating the liquid, adding a small amount of cyclodextrin as a seed crystal and recovering the precipitated cyclodextrin.
