Abstract Purpose: To find out a low-cost, safe, efficient method to tenderize mutton. Methods: The effects of different
treatments, i.e., combination of salting and tumbling under either vacuum or atmospheric conditions, and vacuum tumbling,
were examined on the tenderness of sheep semitendinosus muscle as assessed by shear force, pH, cooking loss, myofibrillar
fragmentation index (MFI) value, collagen content and solubility, and the decomposition of myofibrillar proteins. The results
showed that all three treatments had significant effects on the above tenderness indicators of mutton. Conclusion: Vacuum
tumbling provides the best tenderization of mutton.
