摘要：The paperproposed to usemagnetiteas biologicallyactive substancesin food.The human bodyonlyto a small extentcan control theintake of ironfrom food andhas no control overits expenditure. With a negativebalanceof iron metabolisminitiallyconsumesiron,thenthere istissueiron deficiency, which is manifested inthe form of disruptionof enzymatic activity andrespiratory functionin tissues, and then iron deficiency anemia develops. The solubility ofultrafine powdersof magnetitehas been studiedunder conditions simulatingthe processesof the gastrointestinaltract. The model parametersof the experimentwere chosen in accordancewith the termsof the humangastro-intestinal digestion, temperature, pH, digestive juices, as well as the timewhen digestive juicesare in the digestivetract. It is shownthat the solubilityof magnetitedepends on the durationof the experiment andpHmedium. The results of spectrophotometricand atomic absorptionspectrometry analysis are shown.
