title: Changes in proteins during the ripening of Spanish dried beef 'Cecina'.
abstract: Changes in the solubility of sarcoplasmic and myofibrillar proteins were tracked in Semitendinosus and Rectus femoris muscles during the ripening process of Spanish 'Cecina'. The extractability of both types of proteins decreased during the ripening. This phenomenon was more marked in the initial stages of processing. Electrophoretic studies of the myofibrillar proteins showed the virtual disappearance of the myosin heavy chain, troponin C and myosin light chain 2 from the smoking phase onward and the appearance of three components of molecular weight of about 65, 70 and 75 kda during ripening. The remaining proteins did not suffer appreciable changes.
