| Abstract: | Starch is the main carbohydrate produced by all green plants and is
basically found in the seeds, fruits, tubers, roots and stems of various
plants, notably corn, potatoes, wheat and rice. Starch varies widely according
to its source owing to its granular characteristics. About 50% of starch
produced is used in food industry, either as food additive or to improve
functional properties and shelf life of food products. Curcuma angustifolia Roxb.,
commonly known as Tikhur in Hindi, occurs
wildly in many parts of India. It is traditionally
recognized as medicinal plant and also contains starch in its rhizome. In
some forest tubers extraction of starch is simple, whereas this is not always
so with other tuber starches. Maximum recovery of starch with economical
extraction is thus important. Therefore, extraction
of the starch in Tikhur was done
using 1% ammonium oxalate and 0.03 M ammonia solution and purification of
starch was done according to the method of Badenhuizen, 1964. The yield of
starch in 0.03 M ammonia solution and 1% ammonium oxalate was obtained 38.46
and 37.64%, respectively. The granular shape and size of starch granules were
recorded using Scanning Electron Microscope. The shape of C. angustifolia starch granules were small rounded, oval to
elliptical, spherical, elongated and 3.32 m to 32.55 m in
length and 2.29 m to 8.47 m in width. The study
demonstrated that for extraction of starch from C. angustifolia 0.03 M
ammonia solution method described is best and yields significant quantity of
starch. The results would aid the authentication and to check the adulteration
of starch of this species.
