How is starch extracted from a potato plant?
The cells of the root tubers of the potato plant contain starch grains (leucoplasts). To extract the starch, the potatoes are crushed; the starch grains are released from the destroyed cells. The starch is then washed out and dried to powder. Potato starch contains typical large oval spherical granules; their size ranges between 5 and 100 μm.
How are starch granules removed from potato juice?
Powerful washing is needed to flush the starch granules out from the cells – the cells are torn apart in the rasper and form a filtering mat that tries to retain the starch. Water has previously been used for the extraction, but today extraction takes place in closed systems allowing the use of the potato juice itself.
