Foot note:
Method of Extraction of Starch:
The starch is extracted from rhizomes not more than a year old. 
The rhizome is cleaned after removing scales and thoroughly washed for removing soil particles,then pulped it in wooded mortars or grinded well.
The pulp stirred in clean water, fitered, allowe to settle in bottom, and then drained.Wash the starch with fresh water and repeat the process twice.
Finelly clear, odourless, white starch obtained is dried on sheets in the sun.
The maximum available starch from rhizome is about one-fifth of the original weight.

Rhizome of Curcuma angustifolia (Zingiberaceae family)(Kattu koova) is also used for extracting starch.
 But for getting clear starch, the pulp obtained from Curcuma angustifolia rhizomes shold be repeatedly washed for ten times before drying.
