Vitamin A content of fortified maize meal and porridge as purchased and consumed in South Africa

چکیده
In 2003 the Department of Health of South Africa embarked on a mandatory fortification programme of maize meal as part of a nutrition program to alleviate malnutrition. The aim of this study was to determine the vitamin A content in fortified white maize meal and the maize porridge prepared with it as purchased and consumed. The highest mean vitamin A concentration in the maize meal was 261 μgRE/100g and the lowest mean vitamin A concentration was <19 μgRE/100g. Pertaining to regulation the final minimum level of vitamin A in fortified maize meal shall not be less than 187.7 μg/100g (Foodstuffs, Cosmetics and Disinfectants Act, 2003). The average retention of vitamin A in maize porridge as the difference in vitamin A concentration between raw maize meal and cooked porridge was calculated as 39.8%. Although fortification of maize meal can improve the vitamin A intake of the population, it must be regularly monitored and regulate in order to be beneficial. If not then fortification might as well be voluntary.

BACKGROUND There is a need to determine whether iron absorption from iron amino acid chelates is protected from inhibition by dietary phytate and regulated normally by iron status. OBJECTIVE The objective of this study was to compare iron absorption from ferrous sulfate, ferrous bisglycinate, and ferric trisglycinate in whole-maize meal; to determine whether iron from ferrous bisglycinate and...
