Abstract

The combination effect of low voltage electrical stimulation (LVES) and early postmortem (PM) temperature conditioning (2, 16, and 30°C until 3 h PM) on degradation of myofibrillar proteins were determined from Korean native cattle (Hanwoo). Myofibrils were removed at 1, 2, 3, 7, and 14 days of PM storage (2°C) and analyzed for titin, nebulin, desmin, and troponin-T by SDS-PAGE and by Western blot analysis. Degradation rate of myofibrillar proteins was affected by the combination of LVES and temperature conditioning. LVES-30°C treatment resulted in faster degradation of titin, nebulin, desmin, and troponin-T during PM storage than the other treatments. Degradation of titin took place more slowly than nebulin, desmin or troponin-T.
