To investigate the effect of high-pressure processing technology on the tenderness of cattle muscle, four simmental bulls of 2-3 year-old, 500kg gross weight were chosen ramdomly. Semitendinosus was treated respectively by high-pressure at 100, 200 and 300MPa for 2, 6 and 10min after slaughter. The results showed that there was a significant effect on the synthetical index of sensory, SP values and structure of cattle musle and the effect was directly proportional to the pressure and time. The optimum condi...
