INHIBITING MICROBIAL GROWTH OF REFRIGERATED BEEF-MEAT WITH ONION EXTRACT

摘要

IntroductionThe shelf-life of pre-cooked sliced roast beef is limited by the lack of barriers to microbial growth and the development of off-flavors. The quality of pre-cooked roast beef is highly variable and its microbiological safety is of concern. Great emphasis has being placed on the microbiological quality of meat and on searching for alternative mechanisms to reduce natural and cross contamination, thus avoiding major public health problems.Contaminated raw foods, inadequate cooking and the consumption of food from an unsafe source are the factors most commonly associated with reported outbreaks in many countries (Delaquis et al. 1999).
