Abstract

The relationship between the myofibrillar fragmentation and zeugmatin during post-mortem aging was in vestigated by indirect immunofluorescence method using antizeugmatin Antiserum as a measure of meat tenderization. The antizeugmatin antiserum was prepared using bands separated by SDS-PAGE and reacted specifically with zeugmatin, showing no cross-reactivity with the other myofibrillar proteins. By the indirect immunofluorescence method, this antiserum stained the fresh myofibrillar However, the fluorescence intensity decreased with post-mortem time and almost disappeared within 24 hr of storage, in parallel with the myofibrillar fragmentation. It was therefore concluded that zeugmatin can be conveniently used as a measure of meat tenderization during post-mortem aging by immunoflurescence method.
