ABSTRACT:
A process is disclosed for thinning granular starch in an aqueous slurry employing a source of peracid without using metal catalysts. The thinning process is aimed at modifying granular starches by lowering viscosity/increasing alkaline fluidity. It can also be employed immediately before or during cooking (gelatinization) of starch. Sources of peracids are peroxomonosulfuric acid (Caro's acid) or organic peracids such as performic, peracetic or perpropionic acid. Reaction time and temperature are lower than for existing process while product properties are improved.
