The effects of UV-C radiation, modified atmosphere packaging (MAP) and their combination on rainbow trout (Oncorhynchus mykiss) fillets quality were examined during a period 22 days. samples submitted to five conditions: (AP) aerobic packaging; (VP) vacuum (VP + UV-C) radiation; (80% CO2/20% N2) (MAP radiation N2; 106.32 mJ/cm2) storaged at 4 °C. analyzed daily for microbiological (mesophilic, psychrotrophic Enterobacteriaceae counts) chemical (pH, TMA-N, TBV-N, lipid oxidation, ammonia...
Radiation from UV-C has been demonstrated as a potential surface decontamination method in addition to several advantages over regular sanitation methods. However, radiation possibly affects the physicochemical properties of meat products. To determine optimum exposure time for bacterial reduction, 39 chicken breasts, inoculated with pool Salmonella spp., were submitted 3 levels intensities (0.62, 1.13, and 1.95 mW/cm²) up 120 s. After 90 s was determined, changes biogenic amines, total...
The purpose of this study was to elaborate prebiotic yoghurt using ovine milk and different inulin concentrations (0, 2 6%). Samples were submitted laboratory analysis two sensory tests with 100 consumers. results apparent viscosity firmness determined by instrumental each control differed significantly. Just‐About‐Right showed consistency as the main attribute that varied in treatments. According penalty analysis, containing 6% had minor penalties, which indicates its advantage quest better...
The purpose of the present study is to develop a new probiotic yoghurt with mixture cow and sheep milk evaluate on physicochemical, textural sensory parameters these products. For each trial (n = 3), (CM) ewe (EM) were used manufacture yoghurts either (Y1), (Y5) or mixtures ratios 3:1 (Y2), 1:1 (Y3), 1:3 (Y4). Physicochemical (pH, titratable acidity, contents total solids, protein, lipid, ash, water-holding capacity – WHC, spontaneous syneresis), (firmness apparent viscosity),...
Resumo Este trabalho teve por objetivo analisar a percepção dos manipuladores de alimentos em relação às práticas higiene no local e correlacionar com os resultados das análises bacteriológicas observações sistematizadas, um Restaurante Universitário Rio Janeiro. A da foi investigada meio questionários autorresposta. As operacionais foram analisadas pesquisa observacional sistemática. Na bacteriológica, dividida duas etapas, buscou-se identificar presença Coliformes 45°C, Clostridium Sulfito...
ABSTRACT: Veterinary drugs are used in dairy cattle management mainly for therapy and prophylaxis of diseases, which chemicals may leave residues milk. Human exposure the unintentional consumption can lead to side effects development resistant bacteria, representing a considerable concern consumer health. This paper presents occurrence veterinary milk from 2009 2011 Brazil, monitored by Official Program Analysis Residues Drugs Foods Animal Origin. A total 961 samples were collected retail...
The inactivation kinetics of Listeria monocytogenes in whey dairy beverage submitted to ohmic heating processing (OH, 3 V/cm, 57.5–60 °C for 38-4 min) was investigated. Besides, the physicochemical characterization and sensory analysis processed by OH were performed. at 65 resulted a reduction rate (RR) 2.10 log CFU/mL−1min−1 while conventional (CP) RR 1.38 monocytogenes. Concerning parameters, OH-treated beverages presented lower pH hydroxymethylfurfural values improved scores, despite...
Our objective was to examine the effects of high hydrostatic pressure (HHP) on physico-chemical properties and bacteriological quality caiman (Caiman crocodilus yacare) meat. Caiman tail meat cut into 25 g chunks, individually vacuum packaged, allocated four treatments: non-treated (NT; not subjected HHP), samples HHP at 200 MPa (P2), 300 (P3), 400 (P4). Physico-chemical properties, fatty acid profile, were evaluated. All treatments (P2, P3, P4) demonstrated lower (P < 0.05) microbial loads...
Summary This study evaluated the influence of packaging atmosphere (air versus 50% N 2 /50% CO ) on microbiological (mesophiles, psychrotrophs), physical (gas measurement) and chemical ( pH , total volatile basic nitrogen [TVB‐N], NH 3 H S biogenic amines) parameters in freshwater prawns during storage at 0 ± 1 °C for 240 h. To select most appropriate packaging, 21 batches each treatment were analysed. Both permeability combination gases affected shelf life, but modified‐atmosphere (MAP) was...
The influence of different emulsifying salts ( ES ) on the physicochemical parameters and sensory qualities spreadable processed cheese SPPC was evaluated. fat moisture contents were not affected significantly by varying proportions . replacement sodium‐based polyphosphate blends their monopotassium phosphate counterpart at 25% (w/w) markedly improved quality (on a weight basis). An acceptable labelled as ‘reduced sodium’ product obtained using blend commercial (1:1 w/w) added 1.2% total...
ABSTRACT: The aim of the present research was to evaluate differences in chemical properties and physical structure yoghurt produced with milk from different species (sheep, cow, goat). For each trial, whole raw sheep (S), cow (C), goat (G) were used manufacture 4L yoghurts (Y) (SY, CY, GY, respectively). SY demonstrated greatest (P<0.05) values total solids, protein, lipid contents, reflecting on greater firmness, apparent viscosity water-holding capacity, lower syneresis index than CY...
This work investigated the effects of different packaging methods (air and vacuum) combined with irradiation (0.0, 2.0 3.0 kGy) on preservation chicken breast fillets stored at 1ºC for up to 18 days by sensorial test, determination pH bacterial growth. The findings indicated that post-irradiation lag phase increased dose, leading an extension in shelf-life. Vacuum-packed samples irradiated kGy exhibited longest shelf life. Among analyzed bacteria, coliforms Listeria spp. were most sensitive...
The compounds formed in fish spoilage process have been frequently used to assess the quality of different species. Quality indices based mainly on concentration products nucleotide degradation and biogenic amine content proposed. However, these indicators must be calculated considering intrinsic extrinsic factors that may affect both, formation rate pattern. In relation analytical methods, regardless methodology chosen, extraction stage is critical. High performance liquid chromatography...
