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...
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...
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,...
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...
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...
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 (
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...
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...
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...
This work aimed to evaluate the growth, production and wood quality a clonal hybrid (Eucalyptus grandis x Eucalyptus urophylla) produced in integrated crop-livestock-forest systems (iCLF) monoculture. The study was carried out an iCLF system monoculture stand, both municipality of Sinop, state Mato Grosso, Brazil. Diameter (at 1.3 m height), total height (volume) trees were evaluated, along with (growth strains density). parameters analyzed according different positions plantation (lines...
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,...
O objetivo deste estudo foi avaliar o grau de contaminação mercurial em alguns representantes da biota aquática ecossistema.Foram analisados 24 exemplares acará (Geophagus brasiliensis), 18 tainha (Mugil sp.), robalo (Centropomus 10 siris (Callinectes sp.) e pools cracas (Balanus sp.).Para a determinação concentração mercúrio total, utilizou-se analisador Bacharach Coleman, modelo MAS-50 B, baseado na técnica espectrofotometria absorção atômica por arraste vapor frio.O tratamento constou uma...
