2.5.2. Purification of myofibrillar proteins
Changes in protein state (oxidation and surface hydrophobicity)
were evaluated onmyofibrillar proteins purified according to the method
of Martinaud et al. (1997) with slight modifications in the case of
marinated samples. Protein physicochemical state being very sensitive
to pH and ionic strength, to prevent any artefact due to the purification
process, marinated samples were prepared and analysed in the same
solutions as used for marinating.
