OXIDISED STARCH

Oxidised starch is a chemically modified starch created by treating native starches (like corn, potato, or tapioca) with oxidizing agents such as sodium hypochlorite. 
Oxidised starch process breaks down starch molecules, resulting in reduced viscosity, increased whiteness, and enhanced film-forming, binding, and gelling properties compared to raw starch. 
Oxidised starch is a chemically modified starch produced by treating natural starch (usually from corn, potato, wheat, tapioca, or rice) with controlled oxidizing agents such as sodium hypochlorite or hydrogen peroxide.
