Bacteriocin-like substance produced by Pediococcus acidilactici CE51 as a biopreservative in orange beverage

摘要: This work aimed to study the bacteriocin-like inhibitory substance (BLIS) produced by Pediococcus acidilactici CE51 in orange beverage artificially contaminated with Listeria monocytogenes and Enterococcus faecium. The BLIS was stable for 35 days at −20°C or −80°C and at 50°C for 1 h. In addition, it was not influenced by pH (2.0 and 6.5). Its biopreservative effect against Enterococcus faecium was better than sodium benzoate (1 log CFU/mL of difference). In addition, a reduction in L. monocytogenes of 5 log CFU/mL was observed (p < 0.05). The BLIS demonstrated the potential to be applied in the food industry as a biopreservative in an orange beverage.
