In this study, enzyme (thermoase) hydrolysis was applied to the porcine blood order to increase the iron content and solubility. It was confirmed that content of iron was increase up to 158.11 mg/100 g porcine powders after 0.2% thermoase treatment at 60℃ during 4 hr. The solubility of porcine blood powders was higher than other enzyme (various protease), temperature, reaction time. This optimized conditions were also worked to the in vitro iron bioavailability rate increasement, the bioavailability of hydolyzed porcine powders was 3-fold higher than that of an iron supplement on the market. These results indicate the possibility of porcine blood powder in iron supplements market as natural material. Also utilizing of reduced porcine blood will be possible to improve environmental issues.
