The present invention relates to dietary compositions and oral compositions having an anti-dental caries function. The present invention provides dietary compositions and oral compositions having an anti-dental caries function which contain a buffering agent having a pH buffering action in the oral cavity.

Compositions having anti-dental caries function

A method for extracting a hydrophobic group-containing water-soluble organic compound, comprising the step of bringing an aqueous solution containing the hydrophobic group-containing water-soluble organic compound and a saccharide into contact with a polar organic solvent to obtain an aqueous phase and an organic phase, whereby the hydrophobic group-containing water-soluble organic compound is transferred to the organic phase. The saccharide concentration of the aqueous solution may be at least 12 g per 100 ml of the aqueous solution. The aqueous solution may further contain a phase separation assisting agent. The phase separation assisting agent may be selected from the group consisting of sodium chloride, sodium citrate, magnesium sulfate, and ammonium sulfate.

Method of extracting and method of purifying an effective substance

A method of producing a phenol derivative glycoside is provided. The method comprises the step of allowing a saccharide and a phenol derivative to react with each other in the presence of an enzyme to produce the phenol derivative glycoside. The enzyme is selected from the group consisting of neopullulanase, cyclomaltodextrinase, maltogenic &#x3b1;-amylase, and saccharifying amylase having cyclodextrin synthesizing capability.
