<P>PROBLEM TO BE SOLVED: To provide dietary fiber powder effectively utilizing a palm oil trunk and generally usable for a variety of foods and drinks and a food containing the dietary fiber powder and to provide a method for producing the powder. <P>SOLUTION: Lumber prepared by cutting and forming the palm oil trunk is pulverized, heated-air dried to about 6-18% of moisture content and then sieved into dietary fibers and vascular bundles. Thereby, the dietary fiber powder derived from the palm oil trunk and containing about ≥70% of the dietary fibers and further hemicellullose, pectin, cellulose, lignin and a mucilage is obtained. The sieving may be carried out at about 35-400 mesh. The cutting and forming may be carried out by a method for removing about 5 cm of trunk bark from a log obtained by laying and cutting the palm oil trunk and pulverizing the log with a pulverizer or forming the log into a square or a board material with a sawing machine. Furthermore, drying may be carried out after freezing to about -70 to 0°C or heated-air drying and freeze-drying in a drying chamber or air drying under natural conditions at about 15-35°C atmospheric temperature. <P>COPYRIGHT: (C)2004,JPO |
