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 objective of this study was to evaluate the effect environmental factors on fatty acid profiles and physicochemical composition Crassostrea gasar cultured in two locations with differences salinity precipitation gradients. period divided into four seasonal divisions—the rainy–dry transition period, dry season, dry–rainy rainy season. salinity, pH temperature were measured at each site during specimen collection. A total 712 oyster samples used for profiling analysis. Salinity parameters...
Papaya is a fruit of great economic importance worldwide, but still presents high rate postharvest losses.Among the different reasons explaining this phenomenom, intensive labor and inappropriate storage conditions are main ones.Carnauba wax nanoemulsion (CWN) coating may be an alternative to problem, preserving quality.Therefore, experimental CWN was developed set three trials were conducted evaluate its performance on papaya fruits solo type.On first trial, applied at concentrations 4.5,...
Os metais traço apresentam grande toxicidade quando presentes em teores elevados nos organismos humano e animal. No ambiente aquático, alguns elementos formam compostos orgânicos que bioacumulam tecidos de vivos. moluscos bivalves se destacam, pois possuem participação na dinâmica contaminantes metálicos no marinho devido à capacidade concentrá-los níveis mais água. mexilhões são constituem bons indicadores biodisponibilidade metais, sendo amplamente utilizados como biomonitores ecossistemas...
O mercúrio (Hg) é um metal traço de relevância na área alimentos em função da alta toxicidade, dos altos níveis absorção e baixas taxas excreção, sendo acumulado cadeia alimentar, atingindo o homem, a partir do consumo pescado, podendo representar risco à saúde humana.Considerando esses fatores, objetivo deste estudo foi traçar perfil grau contaminação mercurial atum in natura (Thunnus albacares) conserva sp.), Meca (Xiphias gladius), corvina (Micropogonias furnieri), peixe-espada...
Summary This research aimed to evaluate the influence of different high‐intensity ultrasound (HIU) levels (control: 0; low: 276.36; moderate: 422.67; and high: 747.79 W cm −2 ) stored in aerobic conditions for 7 days at 4 ± 1 °C on instrumental colour, metmyoglobin reducing activity (MRA), oxidative stability texture Longissimus lumborum (LL) from Nellore ( Bos indicus cattle. HIU moderate level samples exhibited higher P < 0.05) lipid protein oxidation, whereas high showed MRA than...
Researchers recognize the silent, negative and deleterious effects caused by mercury pollution in gold mining areas. Freshwater turtles are culturally part of diet riverside populations Amazon region this area presents (Hg) issues mainly due to activities. Thus, research aimed evaluate total (THg) content different organs Amazonian giant river turtle (
ABSTRACT: The production chain of Penaeus vannamei require detailed quality evaluation from farm to processing plant, maintain the standards. We evaluated impact steps in main defects P. as red hepatopancreas, detached cephalothorax and post-mult. Red hepatopancreas exhibited highest defect incidence, which are related capture method post-harvest handling procedures. showed a positive correlation (r = 0.56; P 0.008) with post-molts. Principal Component Analysis (PCA) explained 53.91% total...
O presente estudo verificou a cinética mercurial em órgãos, tecido muscular e conteúdo estomacal de duas espécies peixes marinhos predadores, identificando os locais maior acumulação desse metal. Para o processo analítico, foi utilizada técnica espectrofotometria absorção atômica por arraste vapor frio. A distribuição Hg nas porções analisadas apresenta ampla dispersão. atum, variação 0,004 µg.g-1 no fígado, brânquias baço, 0,172µg.g-1 muscular. pescada bicuda, entre 0,013µg.g-1 0,250µg.g-1...
EFEITO DO TRATAMENTO TERMICO SOBRE AS PROPRIEDADES FISICAS E MECÂNICAS DE PAINEIS MDF O objetivo deste trabalho foi avaliar o efeito do tratamento termico em paineis de MDF, visando principalmente a melhoria sua estabilidade dimensional. Os foram obtidos junto ao comercio local, fabricados com materia-prima Eucalyptus sp. e resina sintetica ureia-formaldeido. Foram utilizadas vinte cinco amostras para os ensaios, sendo estas subdivididas diferentes grupos estufa utilizando as temperaturas...
A irradiação de alimentos é uma opção tecnológica para minimizar problemas perdas alimentos, pois reduz as alterações provenientes da atividade bacteriana, estendendo a validade do produto.Neste estudo foram irradiados camarões (Litopenaeus brasiliensis) com doses 1,5 e 2,5 kGy, após 30 dias armazenamento sob refrigeração (2°C ± 2°C), o objetivo avaliar os efeitos sobre comercial através parâmetros físico-químicos, microbiológicos sensoriais.Foram avaliados pH, bases voláteis totais (BVT),...
Abstract: Trichiurus lepturus (Actinopterygii, Perciformes) is a commercially and economically important fish. A total of 60 specimens this cutlassfish were collected the coast municipalities Niterói Cabo Frio, state Rio de Janeiro, Brazil. The fish measured, necropsied, filleted had their organs investigated for digenetic trematodes. Taxonomic identification was based on morphological morphometric characters. T. parasitized with adult Lecithochirium monticellii. Parasite indices prevalence,...
Abstract The Hypancistrus genus is recognized in the Río Orinoco basin and Rio Xingu Guiana Brazilian Shields, respectively. Some of its species are important ornamental fishing. Despite this significance, many other undescribed still awaiting to be named. Here we describe a new found on bedrock Tocantins, representing an extension distribution genus. Also, multigene phylogeny presented evaluate taxonomic position concerning congeners. differs from all congeners by (1) hypertrophied...
We aimed to evaluate the influence of muscle source [longissimus lumborum (LL) and psoas major (PM)], diet (grain-finished pasture-finished), days refrigerated storage (0, 5, 9) on instrumental color oxidative stability extended-aged (60 days) beef from Nellore bulls employing structural equation modeling (SEM). The SEM considers different mathematical models demonstrate effect causal relationships among parameters analyzed. When (LL PM) was combined, both feeding systems pasture-finished)...
