چکیده
According to WHO report, more than ۲ billion people in the world suffer from micronutrient deficiencies caused largely by a dietary deficiency of vitamins and minerals. Fortification of some staple foods is one of the simplest and most practical methods to combat micronutrient deficiencies for both poor and wealthy societies. In this study sunflower oil was fortified with different concentrations (۰.۱, ۰.۳, ۰.۹, ۱ and ۱۰ μg/mL) of vitamin D۳. Then the reduction of vitamin D۳ for concentrations of ۰.۱ and ۰.۹ μg/mL at different times (۰, ۲, ۴, and ۶h) and cooking temperatures (۷۰, ۱۱۰, and ۱۵۰○C) and also at deep-fat frying temperature of ۱۸۰○C, concentrations of ۱ and ۱۰ μg/mL were investigated.The results showed that the relative resistance of this vitamin observed at ۷۰ ○C. Over the specified time, at ۱۱۰, and ۱۵۰ ○C, the amounts of vitamin D۳ were decreased significantly. At ۱۸۰ °C (deep frying), more than ۶۰% of vitamin D۳ was decomposed. Also, after heating, pyro- and iso-pyrocalciferol were detected as vitamin D۳ decomposition compounds at deep-fat frying temperature using GC-MS. Based on the obtained results, free- vitamin D۳ added to cooking oil can be stable at temperature lower than ۱۰۰○C but for higher temperature, encapsulation of it is proposed.کلیدواژه ها
