Abstract
The effect of autoclaving on meat enhancement of dietary iron bioavailability was studied. Meat was mixed with FeSO4 or hemoglobin to obtain ratios of iron from meat to iron from FeSO4 or hemoglobin of 100:0, 75:25, 50:50, 25:75, and 0:100. One-half of each mixture (except meat:FeSO4 mixture 0:100) was autoclaved for 90 min at 15 psi. The meat mixtures were lyophilized and formulated into diets to provide approximately 35 mg Fe/kg. Hemoglobin regeneration efficiency (HRE) was determined as the percent iron gained as hemoglobin relative to the iron consumed. Heat increased the HREs of meat/hemoglobin mixtures and of hemoglobin. Heat did not affect the HRE of meat or meat/ferrous sulfate mixtures. Meat did not significantly enhance the bioavailability of total dietary iron.
