Red cell concentrate, serum, albumin, and immunoglobulin fractions were separated from porcine blood collected at a HACCP-implemented (Hazard Analysis and Critical Control Points system-implemented) slaughterhouse in Hermosillo, México. Functional and microbiological properties were examined. Red cell concentrate and serum isolates were high in protein (92 and 85%, respectively) but limited in methionine and isoleucine. Porcine serum and albumin fractions showed emulsifying properties comparable to bovine sources. Porcine immunoglobulins were 96% soluble. All fractions were of excellent microbiological quality. These results indicate the optimal sanitary conditions during slaughter and processing procedures, as well as the potential functionality of porcine protein fractions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
