VASQUEZ M, Sandra Milena; SUAREZ M, Héctor y ZAPATA B, Sandra. USE OF ANTIMICROBIAN SUBSTANCES PRODUCED BY ACID LACTIC BACTERIAS ON MEAT CONSERVATION. Rev. chil. nutr. [online]. 2009, vol.36, n.1, pp.64-71. ISSN 0717-7518. http://dx.doi.org/10.4067/S0717-75182009000100007.
The use of lactic acid bacteria (LAB) for food bio-preservation has taken great importance nowadays due to its capacity for controlling pathogenic and spoilage microorganisms. Application of bi-o preservative strains as well as extracts and metabolites produced by them have demonstrated to control diverse undesirable microorganisms improving the enlargement of foods shelf-life and safety against bacteria that can affect the consumerís health. This review involves aspects of food bio-preservation and specifically of meat and meat products susceptible of alterations and attacks of diverse microorganisms. Bio-preservation methodologies of common use in foods are detailed as well as more outstanding aspects of metabolites produced by LAB, making special emphasis on bacteriocins, antimicrobial substances that have demonstrated its effectiveness to control diverse microorganisms and have had successful application on foods. The use of bio-preservation is revised, considered as a technology barrier that combined with other conservation methods like refrigeration and joint to good manufacturing practices can be an interesting option to diminish the addition of chemical preservatives, providing safe foods naturally preserved.
