PCT No. PCT/SE87/00369 Sec. 371 Date Jun. 16, 1988 Sec. 102(e) Date Jun. 16, 1988 PCT Filed Aug. 24, 1987 PCT Pub. No. WO88/01138 PCT Pub. Date Feb. 25, 1988.A process for manufacturing potato fibers and potato fibers manufactured in the process. According to the process, potatoes are subjected to washing, dividing into potato juice, starch and pulp, and subsequently separating of starch from potato juice and pulp. The process is distinguished in that solid impurities are removed from the pulp, potato juice being defoamed and added to the pulp to form a pulp/potato juice mixture which is relieved of solid impurities by density separation. Subsequently, the pulp is dewatered to remove part of the potato juice, and the dewatered pulp is refined such that the content of potato juice and dissolved salts in the pulp is reduced in that the pulp is prepressed to a dry solids content of 20-30% and thereupon washed by adding water to obtain a dry solids content of 11-16%, whereupon the pulp is finally pressed to a dry solids content of 20-30%. Finally, the refined pulp is subjected to drying and grinding to the final potato fiber product. |
