A rapid method for the determination of sulphur dioxide in sulfited potato flakes

Abstract

A simple and rapid method is presented for the determination of sulfite in dehydrated potato flakes. Special extraction and filtration techniques are used to prevent potato cell rupture and subsequent release of the starch. Presence of cooked starch would interfere greatly with filtration of the extract. An iodimetric titration and simple calculation yield reproducible results with little effort or time.
