The Lactobacillus curvatus strain deposited as DSM18775 is used as a biopreservative culture in a wide range of meat products due to its production of bacteriocin. The present invention relates to Lactobacillus curvatus strains having an extended lag phase of at least 24 hours at 30°C relative to DSM18775. In a presently preferred embodiment, the strains are mutants of DSM18775, such as the Lactobacillus curvatus strain deposited as DSM32590 and the Lactobacillus curvatus strain deposited as DSM 32591. Further, the invention relates to a method for inhibiting Listeria in a food product comprising adding bacteria of a Lactobacillus curvatus strain according to the invention to a food product in a concentration of at least 10 5 CFU/g.

36 RESUMEN Los lactobacilos utilizados en esta invención son aislamientos que provienen de cárnicos artesanales y fermentados así como de material de origen vegetal del 5 altiplano central de México. De un total de 60 cepas de lactobacilos, 7 fueron seleccionadas debido a su capacidad antagónica contra microorganismos patógenos y contra microorganismos deterioradores de productos cárnicos crudos y procesados. 10 Se desarrolló un método para conservar un producto alimenticio, tal como carne, ya sea cruda o procesada (embutidos), incluyendo las etapas de inoculación de la carne con una cantidad eficaz bacterias aisladas no deterioradoras y no patógenas, con el fin de inhibir 15 competitivamente el crecimiento de patógenos y bacterias deterioradoras no deseadas en los productos cárnicos.
摘要:
The present invention relates to preservation of meat products. In particular new additives are provided for effective inhibition or prevention of bacterial outgrowth in meat products. The present inventors found that a combination of a cationic surfactant and nisin is particularly effective in the inhibition or prevention of bacterial outgrowth in meat products. The combinations, more in particular, proved to be effective at levels that do not result in significant effects on the flavor and/or taste of the products. The present inventors furthermore found that treatment of meat products with the combinations of this invention had a favorable effect on the visual appearance (color) of the meat products. The present invention provides preservative compositions, the use of thereof as well as the meat products containing them.

摘要:
A food preservative system and method for preserving a food composition is described. The food composition can be high in protein, contain meat and mayonnaise and is shelf stable for at least 30 days. The preservative system has a component that interferes with the permeability of the cell membrane of spoilage bacteria and pathogens and another component that penetrates the same in order to kill or inhibit growth of such organisms.
