<P>PROBLEM TO BE SOLVED: To provide a β-glucan product, a simple and efficient method of extracting β-glucan, or at least a substitute useful for public. <P>SOLUTION: The present invention discloses a method of obtaining the β-glucan from a cereal by extraction with water, without deactivating an enzyme contained in the cereal; a method of controlling a molecular weight of the β-glucan extracted from the cereal, by controlling an extraction time; a method of recovering the β-glucan from an aqueous solution of the β-glucan, comprising the freezing of the aqueous solution, the thawing thereof and the separating of a solid component from a resulting suspension; and the β-glucan obtained by the methods. Gel is formed when the heated solution of the β-glucan is cooled. The present invention discloses also the use of the β-glucan as therapy of various diseases, an additive into cosmetics and foods, and a film forming agent; and discloses the cereals, from which the β-glucan is extracted, for use as animal feeds or for use in brewing. <P>COPYRIGHT: (C)2009,JPO&INPIT |
