摘要: In this study, the effect of high-pressure processing (HPP) on the physico-chemical properties and microstructure of prepared chicken breast meat products was investigated. The result showed that the pH and TBARS values of the prepared chicken breast gradually increased, while the total volatile basic nitrogen value constantly decreased with the increase of pressure (0.1-500 MPa). In addition, the colour attributes (L* anda* values) and texture indexes (hardness and chewiness) significantly improved as the pressure increased. The results of low-field nuclear magnetic resonance demonstrated that the peak area of immobilised water (T-22) first enhanced and then declined with the increase of pressure, reaching the maximum value at 200 MPa. Moreover, the integrity of microstructure and protein secondary structure of prepared chicken breast were also disrupted. These findings could serve as a theoretical basis for a better application of HPP in prepared chicken breast meat products.
