| A triple fortified salt (TFS) containing vitamin A, iron and iodine was produced and studied under two controlled climatic conditions: 40°C 60% and 100% relative humidity (RH) for three months.; The highest vitamin A stability was observed in premixes made with Dry Vitamin A Palmitates (250 CKCWD, 250 Food and 500; BASF Corporation, NJ, USA). In our best formulation TFS retained of 65 ± 2% vitamin at 40°C, 60% RE The highest vitamin A retention at 40°C and 100% RH was 45 ± 1%. The TFS containing vitamin A acetate retained a maximum of 48 ± 5% vitamin at 40°C, 60% RH. Introduction of all three micronutrients into one premix particle resulted in reduced vitamin A retention to ∼7% at 40°C, 60% RH.; Vitamin A was more stable with ferric NaEDTA than with any other iron compound. The source of iodine did not significantly affect vitamin A retention. |
