A coating composition comprising a starchy material, said material having:
- a number average molecular weight (Mn) of 3 500 to 20 000 Daltons,
- a granular structure before solubilisation,
- a solubility at pH 7 and 20°C (S1) of 30-90%, and
- a solubility at pH 10 and 35°C (S2) which is at least 10% greater than S1. |
