Food Structure

Abstract

Ante-mortem changes to muscle microstructure are influenced in many ways. During pre-natal cell differentiation and growth , myoblasts develop and mature into cells with quite different characteristics. Incorporated into the genome of these cells is the ability to synthesize a wide variety of filaments which occupy specific niches within each myofibril. During post-natal development , depending upon the particular precursor cell lines, different fiber types are produced. These are especially important in contributing to the ultimate palatability of meat. In this paper several factors which influence ante-mortem changes to muscle microstructure are discussed. While some of these are better understood than others, all of them , nevertheless, are important
