A sample of potato starch was cross‐linked with phosphorus oxychloride and its reaction with iodine compared with that of the parent starch using an amperometric titration method. Both starches had a similar iodine binding capacity but differed considerably in the rate of reaction with iodine. With the parent starch equilibrium was reached within a few seconds, whereas the cross‐linked starch required up to 30 minutes.
