Summary To determine the influence of storage conditions on potassium iodide (KI) stability, its traditional carrier – iodised table salt and alternative collagen carriers (i.e. iodinated collagen fibre and collagen hydrolysate) were stored at high (90%) and medium (60%) relative humidity of air. At medium humidity, these carriers were additionally stored at limited and unlimited access of air. The stability of KI was estimated by determining iodine retention during storage. The obtained results showed that the storage of iodised table salt resulted in iodine content decrease. The iodine losses in the salt tended to increase at high humidity or unlimited access of air. However, application of collagen preparations as carriers increased the KI stability, reducing iodine losses during storage and making them independent on the storage conditions.
