    Abstract:
    Marination using various ingredients has been widely used to improve microbial safety and quality of chicken products at retail markets. The objective of this study was to investigate the effects of commercial marinade seasoning and cultured sugar/vinegar blend on Campylobacter jejuni and Salmonella Typhimurium populations during refrigerated storage. In addition, their effects on the texture of precooked chicken breasts during frozen and refrigerated storage was investigated. Chicken breasts inoculated with 4.5 to 5.0 log cfu/g of C. jejuni and Salmonella Typhimurium were treated with 3% cultured sugar/vinegar blend with and without 0.6% polish rub seasoning containing 32% herb content. Breasts were then vacuum-packaged and stored at 4 and 10°C. Survival and growth curves were fitted to the Baranyi equation to determine survival and growth kinetics of C. jejuni and Salmonella Typhimurium. In addition, the vacuum-packaged precooked chicken breasts with different marination treatments were subjected to 3 freeze-thaw cycles and shear force was measured. At 4°C, the populations of C. jejuni and Salmonella Typhimurium decreased, regardless of treatment group during storage. The greatest survival for C. jejuni was observed in untreated chicken breasts. At 10°C, the growth of Salmonella Typhimurium was completely prevented in precooked chicken breasts treated with 3% cultured sugar/vinegar blend, regardless of the presence of 0.6% seasoning. The 3% cultured sugar/vinegar blend also improved the tenderness of frozen chicken breasts and refrigerated, ready-to-eat chicken breast. Therefore, a natural blend of cultured sugar and vinegar can be used as antimicrobial and texture-modifying agents for poultry meat and poultry products.
