<P>PROBLEM TO BE SOLVED: To provide a yeast cell wall with high food fiber content without needing a chemical treatment or physical treatment while attaining effective use of a yeast extract residue excessively generated as a byproduct of yeast extract and reduction in amount of the yeast extract residue. <P>SOLUTION: After a cell wall lytic enzyme free from protease is worked on the yeast extract residue, heat treatment is performed at 70-80°C for 10-20 minutes to separate a cell wall into a fraction mainly composed of cell wall and a fraction mainly composed of protein, and the fraction mainly composed of cell wall is dried, whereby a yeast cell wall with a food fiber content of 50% or more is obtained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
