Abstract Porcine blood is one of the main by-products in live pig slaughtering process. In our country there is plenty of hog blood resources most of which is discharged, just little is made use of, causing serious waste of precious resources. Extraction of heme by organic extracting agent was studied in this paper and the optimum conditions through orthogonal test is: during hemolysis add aqua destillata 1.0 fold, ethanol 0.25 fold and chloroform 0.2 fold; adding 4 times acetone for separation and adjusting pH3.0; during extracting add 1.4 times NaAc of 1.0mol·L and regulate pH5.0. By this procedure, extraction rate of heme is over 28.6%.
