Effect of high-pressure treatment on processing quality of tilapia meat fillets
Tilapia fillets were treated under 50–300 MPa at 25 °C to examine the change of their processing quality. The gel strength from the tilapia meat treated at 50 MPa for 1 h was 1.2 times as that of fresh meat, but there was a 25% decrease for that treated at 250 MPa for 1 h. Extraction of water-solubl...

Zusammenfassung: | Tilapia fillets were treated under 50–300
MPa at 25
°C to examine the change of their processing quality. The gel strength from the tilapia meat treated at 50
MPa for 1
h was 1.2 times as that of fresh meat, but there was a 25% decrease for that treated at 250
MPa for 1
h. Extraction of water-soluble proteins was barely affected by high-pressure treatment; however, that of salt-soluble proteins decreased 60% after treating at 250
MPa for 1
h. The actomyosin was extracted below 10% for the meat treated beyond 200
MPa. The liability to denaturation indicates that pressure treatment was applicable to tilapia processing not for storage. |
