(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.

| 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. |
