Efficient role of BacTN635 on the safety properties, sensory attributes, and texture profile of raw minced meat beef and chicken breast

Bacteriocin BacTN635, produced by Lactobacillus plantarum sp. TN635, was purified and characterised in previous work. In this study we report the biotechnological application of this bacteriocin as a biopreservative during storage at 4 degrees C of raw minced meat beef and chicken breast. Overall, the results obtained showed that the addition of the semi-purified BacTN635 at 500 or 1000AUg(-1) in raw minced meat beef and chicken breast can delay the proliferation of spoilage microorganisms, suppress the growth of the pathogenic microorganism Listeria monocytogenes, improve sensory quality, texture attributes, and extend the shelf-life of these two meat products during refrigerated storage. BacTN635 at 1000AUg(-1) could extend the shelf-life, and the meat showed good sensory characteristics. Therefore, treatment with semi-purified BacTN635 can be used as a safe method for preservation of raw minced meat beef and chicken breast.
