Abstract:
The absorption of 59 Fe incorporated into yeast was studied in rats. Yeast was cultured in a nutrient solution to which radioactive 59Fe was added as an intrinsic tag. The 59Fe-enriched yeast was separated from the solution by centrifuge and given to rats by a stomach tube. The rats of the control groups were given the radioactive " Fe together -with ordina-ly yeast plus ferrous sulfate or only with ferrous sulfate separately.All feces were collected until less than 0.5 per cent of the administered dose was present in a 24-hour specimen of feces. The radioactivity in the feces was then measured daily for three successive days. The absorption of iron was calculated by the difference between intake and fecal loss.The result revealed that the absorption of iron in "Fe-enriched yeast (38.7%) was similar to that of ferrous sulfate (38.3%). It indicated that the iron incorporated into yeast was easily to be absorbed.This study afforded the scientific data for researching and popularizing fortified food with iron-enriched yeast.
