چکیده
Background: Iodine has undeniable effects on human in all stages of life and its deficiency during fetal stages causes mental retardation,which incurs huge costs for treatment and care.Objectives: The aim of this study was to evaluate the effect of heat, humidity and light on the iodine content in iodized salt.Methods: In this analytical-descriptive study, five brands of refined iodized salts were randomly selected from supermarkets inBabol City. All tests were performed in the Chemistry Laboratory of Paramedical School in Babol University of Medical Sciences. Inthe current study, the samples were kept for threemonthsunderdifferent conditions of humidity, without humidity, light, darkness,and temperatures of ۳۷°C, refrigerator and ambient. The iodine amount of samples was tested every ۱۵ days using titration methodbased on Britain Pharmacopoeia. Data were analyzed with ANOVA in SPSS.Results: The results showed that iodine was reduced in all samples of refined salts: ۹.۶۹ ۱.۳ for refrigerator temperature withhumidity, ۸.۳۴ ۱.۴ for refrigerator temperature without humidity, ۸.۸۵ ۱.۲ for ۳۷°C with humidity, ۷.۸۰ ۱.۴ for ۳۷°C withouthumidity, ۱۳.۹۶ ۱.۳ for ambient temperature with light and humidity, ۹.۶۱ ۱.۵ for ambient temperature with light and withouthumidity, ۸.۶۴ ۱.۱ for ambient temperature with humidity in darkness, and ۵.۴۱ ۱.۲ mg/L for ambient temperature withouthumidity in darkness.Conclusions: The results indicated that ambient temperature, darkness and non-humidity were the best conditions for keepingiodized salt.کلیدواژه ها
