摘要:Summary Utilization of iron from a new cultivar of dry bean (Cario-ca 80 SH) was estimated using anemic rat by two methods: the slope ratio and the hemoglobin regeneration methods. The bean was incorporated into the diet in the form of whole bean flour (WBF) 7.45mg Fe/100g or as partially decorticated bean flour (DBF), 8.57mg Fe/100g. Hemoglo-bin concentration in the rats' blood at the beginning of the experiment averaged 13.79±0.33g Hb/dl; at the end of the depletion period it ranged from 5.62±0.38 to 6.30±0.39 g Hb/dl blood, difference which was not statistically significant ( p ≤0.05). The bean iron relative biological value (RBV, relative to FeSO4=100) evaluated by the slope ratio method, was 74% for the WBF and 77% for the DBF. The hemoglobin regeneration efficiency was 60.4±6.5, 50.8±3.2, and 52.7±5.7%, respectively, for the iron sulfate (reference source), the WBF, and the DBF.
