Effect of high-pressure processing on the quality of beef and buffalo meat

The present study evaluated the physicochemical and textural attributes of fresh beef and buffalo meats with applied high-pressure processing. Both types of meat were pressurised at 300 and 600 MPa at 20 for 2 min and compared to the untreated samples as the control. The pH values, water holding capacity (WHC), moisture content, cooking loss, yield, colour, Warner-Bratzler shear force (WBSF), and texture profile analysis were examined. The increase in pressure showed a significant (p<0.05) increase in pH and moisture content for both types of meat. The lightness (L*) values of beef and buffalo were increased with an increase in pressure applied. Meanwhile, the redness (a*) and yellowness (b*) values of both types of meat decreased when higher pressure was applied. The hardness and chewiness of treated beef samples increased compared to the control, while no significant differences were observed for buffalo. WBSF of cooked meat were reduced with an increase in the pressure applied for both meat types. In conclusion, the meat applied with 300 MPa pressure showed more effects on tenderisation with minimal changes in the physical appearance.
