The aim of this study was evaluate the effect photodynamic inactivation mediated by eosin Y in Salmonella enterica serotype Typhimurium ATCC 14028, Escherichia coli 25922, Pseudomonas aeruginosa 27853, Staphylococcus aureus 25923 and Bacillus cereus 11778. Bacteria (107 CFU per ml) were incubated with at concentrations ranging from 0·1 to 10 μmol l−1, irradiated green LED (λmax 490–570 nm) for 5, 15 min cellular viability determined. completely inactivated when treated l−1 min. Treatments...
Abstract This study evaluated the rose bengal‐ and erythrosine‐mediated photoinactivation against Salmonella Typhimurium Staphylococcus aureus planktonic sessile cells using green LED as a light source. The free‐living or 2‐day‐old biofilm were treated with different concentrations of photosensitizing agents subjected to irradiation. Only 5 min photosensitization bengal at 25 nmol L −1 75 μ mol completely eliminated S. S . cells, respectively. Erythrosine 500 exposure also reduced...
The reduction in slaughter age with minimum fat and dry aging process improves meat tenderness, however, its shelf-life display has not been studied. It was evaluated the sensorial, color, lipid oxidation, visual acceptance of dry-aged beef (0, 14, 28 days) from young bulls slaughtered different subcutaneous thickness (2.00, 3.00, 4.00 mm). Meat 2.00 3.00 mm had higher acceptability than (p < .05). Dry improved overall consumers. presented lightness oxidation values .05) but similar...
Abstract The fruits of Tamarindus indica L. are consumed worldwide, with various parts the plant being used for medicinal purposes. residues (pericarp and seeds) generated during cellulose processing significant value as they contain bioactive compounds diverse biological activities. objective this study was to evaluate chemical constituents ethyl acetate fraction possible substitutes synthetic properties using ultra‐high performance liquid chromatography coupled high‐resolution mass...
Forty crossbred steers were supplemented with different doses (from 0 control to 6000 mg/animal/day) of natural additive blend containing clove essential oil, cashew castor and a microencapsulated eugenol, thymol, vanillin for 80 days. Carcass characteristics, drip loss, antioxidant activity evaluated 24 h post mortem on longissimus thoracis, the effects aging (until 14 days) water losses (thawing/aging cooking), texture, color, lipid oxidation.The use did not modify (P > 0.05) carcass...
O objetivo deste estudo foi avaliar o binômio tempo e temperatura nas diversas etapas do processo produtivo, analisar os riscos de sobrevivência multiplicação microrganismos nos alimentos oferecidos. Foram mensuradas durante cinco dias não consecutivos as temperaturas referentes ao recebimento, armazenamento, cocção reaquecimento, distribuição da cadeia resfriamento, em um restaurante universitário localizado no oeste Paraná. Observou-se que recebimento houve adequação todas mensurações. No...
The objective of this work was to study the antioxidant activity biodegradable and active packaging containing essential oils. Seven types were produced. In beef, lipid oxidation measured using thiobarbituric acid reactive substance test (TBARS); a microbiological analysis in beef performed for Salmonella spp., coagulate positive Staphylococcus Clostridium sulphite reducer E. coli; measurements carried out on days 0, 3, 6, 9, 12 15 triplicate. All had exhibited capacities acted as an meat....
This study aimed to investigate the antimicrobial activity of kefir fermented fruit by-products against strains Alicyclobacillus spp., and determine their chemical characterization antioxidant activity. According results, extracts for a longer period (72 h) showed greater inhibition, extract acerola by-product 72 h achieved best results. For all strains, Minimal Inhibitory Concentration (MIC) was 0.78%, except A. acidocaldarius subsp. rittmannii, (1.56%). The same applies Bactericidal (MBC),...
This study aimed to evaluate the in vitro antibacterial activity of Baccharis dracunculifolia and Tamarindus indica L. aqueous extract, cashew nut shell liquid (CNSL) natural extracts, clove essential oil (EO) against five species Gram-negative ruminal bacteria. Cultures were grown anaerobic media containing 0.1, 0.2, 0.5 1.0 mg mL-1 extracts or oils. Growth was evaluated by monitoring optical density (OD 600 nm) at intervals 0, 8, 12 24 hours incubation 39° C. The baccharis tamarind CNSL...
This study was carried out to investigate the effects of addition Baccharis dracunculifolia leaves in nature on animal performance, feed intake, ingestive behavior, and blood parameters Nellore steers finished feedlot high-grain diets. A total 40 steers, with an average body weight 412.9 ± 22.0 kg were distributed individual pens, equipped automatic drinkers masonry feeders. The randomly assigned one four studied diets, therefore CONT – basal diet; BAC05 diet inclusion B. natura (5...
Abstract This work was carried out to evaluate in vitro antimicrobial activity of cashew nut shell liquid (CNSL) and clove essential oil (Eugenia caryophyllata) on Prevotella albensis (DSM 11370), bryantii 11371) ruminicola (ATCC® 19189™). The experiments were designed using each bacterium exposed two different doses (1:500 1:5000 g/L Tween) either or CNSL with six replicates. Bacteria cultivated Hobson’s M2 medium Hungate tubes. Cultures without addition any oils considered as control....

Context Natural products, organic trace minerals and yeast have been studied for use as alternatives to antibiotics in improving meat quality acceptability of bulls finished feedlots. Aims This study was conducted evaluate consumers from feedlot-finished fed diets containing antimicrobials with or without a natural product based on live yeast. Methods Crossbred (European × Nellore) (n = 24, age 24 ± 3 months, weight 385.5 3.8 kg) were one four diets: control, additives; three that included...
A preocupação pública com o uso rotineiro de antibióticos e ionóforos na dieta ruminantes aumentou devido ao surgimento bactérias resistentes aos que podem representar riscos à saúde humana. Assim, esforços têm sido empregados para desenvolvimento compostos alternativos substituir ruminantes. Este estudo foi realizado avaliar os efeitos in vitro uma mistura contendo óleos vegetais caju mamona essenciais cravo-da-índia, eugenol, timol vanilina sobre a atividade das Gram-negativas...
