STARCH
» Modified Starches
(Thin boiling starches and dextrins) Thin boiling starches are made by heating acidified starch slurry below the gelationzation temperature. The acid treatment increases the clarity of the paste and decreases the viscosity of starch. Dextrins are made by roasting acidified starch powder. Dextrins of different colours and solubilities are produced by manipulating process conditions. We manufacture following modified starches.

Applications
Thin Boiling starches are used in textile industry for sizing and finishing of cotton goods, in calendar sizing of special grades of paper to improve ink resistance and printability. Dextrins having several binding, coating and adhesive properties find applications in textile and paper industries. Dextrins are also used in foundries for core binding to give strength to mould and to prevent deformation of the core.
