<P>PROBLEM TO BE SOLVED: To provide an easy method for thickening or gelatinizing low-concentration polysaccharide solution or dispersing liquid, an easy method for thickening or gelatinizing polysaccharide solution or dispersing liquid without heating and cooling and adding other components such as positive ion and sugar, and an easy method for thickening or gelatinizing polysaccharide solution or dispersing liquid in a short time in a condition of suppressing salt concentration and sugar concentration low. <P>SOLUTION: This method for thickening or gelatinizing the polysaccharide solution or dispersing liquid comprises arranging an electrode to charge with electricity in the solution or dispersing liquid obtained by dissolving or dispersing polysaccharide such as pectin and gellan gum in an aqueous medium. It is preferable to use polysaccharide having concentration allowing no gelatinization in an untreated condition, and properties of thickening or gelatinizing with the addition of positive ion. An insoluble electrode is used for the electrode, and there is no limitation in voltage, electric current and energizing time. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
