Trials on the Antibacterial Effect of Glucose Oxidase on Chicken Breast Skin and Muscle

Use of glucose oxidase as a possible means to inhibit microbial growth on processed poultry was evaluated. Muscle and skin sections of chicken breast were inoculated with Pseudomonas spp. or Salmonella typhimurium and subjected to either: (1) 60 s dip in 2 units of glucose oxidase without glucose supplementation or (2) 60 s dip in 2 units of glucose oxidase with 4% glucose supplementation. Control groups were dipped in sterilized, distilled water. The Pseudomonas and Salmonella populations were determined for each section. Neither enzyme treatment reduced the initial Pseudomonas or Salmonella populations nor did the treatments inhibit the growth of Pseudomonas during the storage period . Salmonella was inhibited by the low temperature. Therefore, a glucose oxidase enzyme treatment has little potential for extending the shelf‐life of chicken .
