Starch isolated from different plant sources are regarded as vital in food industry, where the granule size and shape determine its function and uses. Native starches irrespective of their sources are not desirable for many applications. Many Indian tribals explored certain Curcuma species as source for starch and prepare various food items, mainly considering its medicinal importance. Presently, a range of highly priced starch powders are available in the market in the label of herbal nutraceuticals. Starch from the rhizomes of eight different native Curcuma species of Kerala and Maranta arundinacea (Arrow root) were extracted, characterised and compared. It was found that size, shape and CHNS data of starch is varying and could be useful in taxonomic identification of the species. The species specific features of the starch granules would also be useful to find its adulterants. The study also points out its edible value.References
