Estimation of available dietary iron The American Abstract. Dietary iron requirements are dependent on the amount and availability of food iron ingested. On the basis of recent studies of food iron absorption employing extrinsic tag techniques the availability of heme iron has been defined and estimates of the availability of nonheme iron based on the amounts of enhancing substances appear possible.
Determination of iron by thiocyanate colorimetry2019-8-14 & 0183; Iron is one of the many minerals required by the human body. It is used in the manufacture of the oxygen-carrying proteins haemoglobin and myoglobin. A deficiency of iron in the body can leave a person feeling tired and listless and can lead to a disorder called anemia. Many of the foods we eat contain small quantities of iron.
