Effects of antemortem injection of proteolytic enzymes (papain, proteasesfrom A. sojae and A. oryzae, and collagenase from Clost . histolyticum) on culled chicken muscles were investigated. Promotion of degradation of Z-line constituent and increase of fragmentation of myofibrils prepared from the chicken muscles treated with papain and protease from Aspergillus were observed during the storage. Digestion of β-subunit, and splitting and swelling of in tramuscular collagen fibrils prepared from the chicken muscles treated with proteases from Aspergillus and collagenase were also detected during the storage. From the point of safety and economy, it seems that proteases from Aspergillus are promissing as a meat tenderizer.
