Reviewer 1 Report

Proteomic Changes in Sarcoplasmic and Myofibrillar Proteins associated with Colour Stability of Ovine Muscle during Post-mortem Storage

This article represents a significant contribution to scientific knowledge about the proteomic characteristics for the sarcoplasmic and myofibrillar proteome of two lamb muscles (M. longissimus lumborum and M. psoas major) and their relationships with muscle colour-stable and colour-labile.

The article is well organized and written clearly. Despite this, some improvements can be made to make the text clearer. The text addresses the subject with scientific correction. Tables and figures are relevant, but some corrections are needed to improve accuracy and clarity. The material and methods are clearly described, which will allow a perfect understanding by other researchers. The results are well discussed with the existing knowledge on the subject.
