Sarcoplasmic and Myofibrillar Protein in Skeletal Muscle of Two Breeds of Pig

Abstract

SUMMARY– The sarcoplasmic and myofibrillar proteins were extracted from two muscles of Landrace and Large White pigs using solutions of low and high ionic strengths. The breed of pig did not affect the extractability of the proteins. It was concluded that the genetic background did not influence the inherent extractability of the muscle proteins before differences in rate of post‐mortem glycolysis (considered to exist between the types of pig studied) could induce changes in protein solubility.
