Abstract

The spoilage vacuum packaged beef remains as one of the major issues that avoid a greater increase in consumption and commercialization of Brazilian beef in our country and also abroad. Considering the importance of Brazil in the world scenario of processing and commercialization of meats, it becomes patent the need to understand factors and conditions leading to spoilage of vacuum packaged beef. The understanding of such conditions is urged in order to implement effective measures aiming at reducing losses associated to vacuum packaged beef spoilage. The microbial ecology of beef and meat products has been studied in several countries, however, in the majority of cases, the elucidation of microbial succession is approached through cultivation-dependent methods , which allow the identification of up to 1% of microbial species involved. Thus, the application of cultivation-independent methods, such as metagenomics and its correlation with products of metabolism (metabolomics) can lead to a profound understanding of microbial succession in the beef cuts as well as the impact of metabolites originated from these events on vacuum packaged beef spoilage. Given the above, through this project we propose to investigate the microbial ecology of Brazilian vacuum packaged beef during storage by the application of metagenomics, metabolomics and predictive modeling tools. This project focuses on the generation of data to provide scientific information related to the microbial ecology of Brazilian vacuum packaged beef that can be used by the productive sector aiming at reducing spoilage problems and losses of products.
