Abstract

Abstract: Impact of papaya extract (PaExt) and high pressure processing (HPP) on survival of Salmonella spp., meat quality and microstructure of chicken breast meat was studied. Samples have been pre-treated with PaExt (0.3%, w/w) in 1, 3 and 5 h, respectively, then followed by 350 and 450 MPa (10 min, 4 °C) HPP treatment. More than 6 log CFU/g of Salmonella were inactivated by 3 or 5 h pre-treatment with PaExt followed by 450 MPa HPP treatment. The Salmonella cells injured by PaExt and HPP tended to take longer time to recover in 16-days storage tests. Regarding meat quality, the color parameters (L*, a* and b* values) and pH value were significantly increased in all pressurized groups. Scanning electron microscopy (SEM) images showed the muscle fibers and connective tissues were severely degraded in the 5 h PaExt and HPP combined treatment. This process may enhance the microbial safety and tenderization of chicken breast meat. Highlight s: Three or 5 h PaExt and 450 MPa HPP caused more than 6-log Salmonella reduction. Enzyme-plus-pressure injured Salmonella cells to require a longer recovery time. SEM images showed severely degraded muscle structures with PaExt combined HPP.
