Pengaruh Penambahan Na2EDTA terhadap Ketersediaan Biologis Besi (Fe) pada Berbagai Olahan Terigu

Abstract

Na2EDTA in generally added to foods to prevent oxidation, discoloration, and enhances iron bioavailability by chelating added minerals. The purpose of this study was to determine the bioavailability of iron changes that occur due to the addition of Na2EDTA in a variety of processed wheat flour. This study used a nested design with factors of processed wheat flour that nested on Na2EDTA wheat flour. The treatment was consists of Na2EDTA wheat flour in the form of 2 levels without Na2EDTA (control) and with Na2EDTA, while wheat flour processed was consists of 3 levels was wheat flour processed by frying (donuts), steaming (steamed bun), or baking (bread). Bioavailability of iron (Fe) was tested by using in vitro method that made a simulation of human digestion using pepsin and pancreatin bile. Test results of this study showed that wheat treated controls and the addition of Na2EDTA showed no significantly difference (p>0.05) in the value of bioavailability. As well as the iron bioavailability on factors of wheat flour processed that nested on Na2EDTA wheat flour (p>0.05). Since rever to the value, there was an increase in wheat flour processed by frying (donuts) way of 9.5654%.
