Abstract

Tenderization and μ-calpain activity were studied along post-mortem maduration (2 h to 21 d) on beef from different biotypes included in the Protected Geographical Indication (PGI) Ternera Asturiana attending to breed (Asturiana de los Valles, AV and Asturiana de la Montaña, AM) and genotype for myostatine mutation causing muscu- lar hypertrophy (mh/mh, mh/+ and +/+). This mutation produced significant differences in meat quality, promoting a faster pH decline and earlier activation of calpains, which resulted in faster proteolysis in AV(mh/mh and mh/+) biotypes, that showed earlier tenderization rate than normal (+/+) biotypes of both breeds. The results showed that differences among biotypes in pH and μ- calpain activity paralleled the tenderization process.
