Antimicrobial activity and chemical characterization of the bark decoction of cumaru stem Ciência Rural
Ferreira,Maria Jaiana Gomes; Nogueira,Patrícia Coelho do Nascimento; Dias,Flayanna Gouveia Braga; Silva,Larissa Morais Ribeiro da; Silveira,Edilberto Rocha; Figueiredo,Evânia Altina Teixeira de.
ABSTRACT: The plant, Amburana cearensis A. C. Smith (Fabaceae), commonly called cumaru, is widespread in the Caatinga cearense, a less known ecosystem in Brazil. A. cearensis is rich in several compounds like protocatechuic acid, tannins, coumarin, flavonoids and phenolic heterosides, such as amburosides A and B, that have been isolated. The aim of this study was to determine the antimicrobial potential and draw the chemical profile of the distinct characteristics of A. cearensis stem bark decoction, for its possible potential as a food conservation agent. The chemical compounds were characterized by one- and two-dimensional 1H and 13C NMR analyses and Liquid Chromatography-Mass Spectrometry (LCMS). The compounds of coumarin, amburosides A and B, and...

In vitro antimicrobial properties of plant essential oils thymus vulgaris, cymbopogon citratus and laurus nobilis against five important foodborne pathogens Ciênc. Tecnol. Aliment.
Millezi,Alessandra Farias; Caixeta,Danila Soares; Rossoni,Diogo Francisco; Cardoso,Maria das Graças; Piccoli,Roberta Hilsdorf.
Several essential oils of condiment and medicinal plants possess proven antimicrobial activity and are of important interest for the food industry. Therefore, the Minimum Inhibitory Concentrations (MIC) of those oils should be determined for various bacteria. MIC varies according to the oil used, the major compounds, and the physiology of the bacterium under study. In the present study, the essential oils of the plants Thymus vulgaris (time), Cymbopogon citratus (lemongrass) and Laurus nobilis (bay) were chemically quantified, and the MIC was determined on the bacteria Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Listeria monocytogenes ATCC 19117, Salmonella enterica Enteritidis S64, and Pseudomonas aeruginosa ATCC 27853. The essential...

Ingredients of mayonnaise: Future perspectives focusing on essential oils to reduce oxidation and microbial counts. Repositório Alice
GOMES, I. A.; GOMES, F. dos S.; FREITAS-SILVA, O.; SILVA, J. P. L. da.
Low-acid mayonnaise produced with raw egg is a product rich in oil, almost a home-made product, but it is susceptible to lipid oxidation and microbial contamination by Salmonella Enteritidis, which results in deterioration of the product and forms undesirable components such as free radicals and reactive aldehydes. A better understanding of the factors that affect and can prevent lipid oxidation and microbial growth is essential to improve the product?s lifetime. This review presents information on the factors that influence lipid oxidation and can accelerate the proliferation of microorganisms. Monitoring these possible factors can reduce the induction period that accelerates rancidity and ensure microbiological safety of the product, possibly increasing...
