‘Pisang tanduk’ (PT) (Musa paradaisiaca fa. Corniculata) is a type of plantain which<br />

contains high amount of starch. However, the starch exhibits low commercial value due<br />

to unexplored potential of its functional properties. This study aims to determine chemical<br />

and functional properties of PT starch and its interaction effects with xanthan gum on<br />

rheological properties of oil-in-water emulsions. Starch will be firstly extracted from PT<br />

pulp and characterized in terms of protein content, amylose-amylopectin content, and<br />

functional properties (pasting properties, swelling power, thermal properties and water<br />

holding capacity). The starch (0.5 – 1.5 %w/w) and xanthan gum (0.5 – 1.5 %w/w) will<br />

be then used in emulsion preparation. Besides the main effects, interaction between<br />

starch and xanthan gum at various levels is also expected to significantly and positively<br />

affect rheological properties of the emulsions. This study will thus benefit food<br />

manufacturers in using non-commercial botanical source of starch in emulsion-based food<br />

products.<br />
