Resumo

The use of antimicrobials in meat products is essential for maintaining microbiological stability. The reformulation by substituting synthetic additives for natural ones is an alternative to provide cleaner label products. Therefore, this work performed a literature search about extracts from fruits and agro-industrial waste with antimicrobial activity that can be applied in meat products. Jabuticaba waste extracts are excellent sources of anthocyanins with antimicrobial and pigmentation potential, capable of being applied in meat products such as fresh sausage, without compromising sensory attributes. Residue from grapes is rich in antimicrobial phytochemicals, mainly catechins, epicatechins, gallic acid and procyanidins. Extracts from different grape by-products and cultivars showed inhibition of Staphylococcus aureus, Listeria monocytogenes, Pseudomonas aeruginosa, Escherichia coli O157: H7 and other bacterial strains. Antimicrobial effects against L. monocytogenes, Bacillus cereus, S. aureus and E. coli O157: H7 were identified in Opuntia extracts. In addition, its application in hamburgers reduced (p < 0.05) aerobic mesophilic bacteria, Enterobacteriaceae and Pseudomonas sp. counts, and at a concentration of 2.5%, improved the microbiological stability of salami without causing sensory and texture changes. These data reinforce the possibility of substituting synthetic preservatives for natural versions, a growing trend that requires researching effective concentrations to maintain the sensory and technological properties.
