Abstract
In the recovery of starch from cell tissue of root crop such as potatoes, by centrifuging, the feed to one of the centrifuging steps, in which an aqueous phase containing fibers and protein is separated from starch milk, is subjected to homogenization to free the fibers of included starch. Thereby, better separation in the centrifuging step is obtained.
Claims5
Process of recovering starch from cell tissue of a root crop, which comprises:
- a. grinding the root crop,
- b. separating the ground root crop into a liquid fraction containing impurities and a solids-containing fraction containing starch and cell tissue including cell fibers having included starch,
- c. adding washing water to the separated solidscontaining fraction and separating the resulting admixture by centrifuging into starch milk and aqueous phase containing fibers in at least one centrifuging step,
- d. homogenizing the cell fibers to free the cell fibers of included starch and separating the homogenization product in the centrifuging step (s) of (c) into starch milk and aqueous phase.
