The aim of the work was to determine the effect of potassium iodide on quantitative and qualitative changes of thiamine during thermal processing (cooking) and storage of turkey meatballs. It was found that cooking resulted in 50% loss of total thiamine. Cool storage increased the losses by about 18%, while the use of the –18ºC temperature for 30 days caused about 10% loss of the total thiamine. Addition of salt iodinated with potassium iodide increased the losses of both free and bound thiamine during cooking and storage by about 6%. Application of a collagen preparation impregnated with potassium iodide, and a mixture of collagen preparation with iodinated salt limited the losses up to 2%.
