The Effect of starter Cultures on the Portuguese Traditional Sausage "Paio do A...
Elias, M; Potes, M.E; Roseiro, L.C.; Santos, C; Gomes, A; Agulheiro-Santos, A.C.“Paio do Alentejo” is a Portuguese dry-cured sausage, made with meat from the Alentejano pig breed. The main aim of this study is to evaluate the benefits of the use of starter cultures on the quality of the sausage, mainly with regard to its sensory properties, rheological characteristics and PAH profile. Three batches of the product were examined: S1-inoculated with a commercial starter comprising Lactobacill...
Contaminated water, stream sediments and soils close to the abandoned Pinhal do...
Neiva, A. M. R.; Carvalho, P. C. S.; Antunes, I. M. H. R.; Silva, M. M. V. G.; Santos, A. C. T.; Pinto, M. M. S. Cabral; Cunha, P. P.The Pinhal do Souto mine exploited a quartz vein containing uranium minerals, mainly autunite and torbernite. This vein intersects a two-mica granite containing 10 ppm U and uraninite. The mine was exploited underground and produced 93,091 kg U3O8 between 1978 and 1989 and was then closed down. Two dumps were left in the mine area and these are partially covered by natural vegetation. Groundwater and surface wa...
PORTUGUESE TRADITIONAL SAUSAGE, ALHEIRA, MADE WITH DIFFRENT MEAT: SENSORY EVALU...
Elias, Miguel; Mota, F.; Fraqueza, M.J.; Barreto, A.S.; Agulheiro-Santos, A.C.At a portuguese traditional meat plant 6 different formulas were used to produce “alheira”, a portuguese traditional fermented sausage, from the north region, usually made with chopped meat from pork and poultry. Formulas were different only due to the type of meat (formula A - beef meat; formula B - poultry meat; formula C - Alentejano pig breed meat; formula D - Alentejano pig breed meat and beef meat; formul...
Effect of Different Storage Conditions on Nutritional and Quality
Palma, V.; Agulheiro-Santos, A.C.; Machado, G.; Rato, A.E.; Cabrita, M.J.; Lozano, M.; Gónzález, D.The sweet cherry ‘Sweetheart’, although having a short shelf life, is highly appreciated by consumers due to its organoleptic characteristics. Different storage methods were tested to study the maintenance of quality during a period of 27 days: 1) cold (air at 1°C and 95% relative humidity) (CC), 2) cold and polypropylene film bags (1°C and 95% relative humidity) (MA) and 3) cold and controlled atmosphere (1°C,...
INFLUENCE OF CELL WALL CALCIUM CONTENT IN FRUIT FIRMNESS DURING THE RIPENING OF...
Rato, A.E.; Nunes, C.; Agulheiro-Santos, A.C.; Barroso, J.M.; Coimbra, M.A.; Riquelme, F.‘Rainha Claudia Verde’ is a regional cultivar of Prunus domestica L. well adapted to a specific region in the south of Portugal. In order to understand the postharvest behavior of this cultivar produced in different orchards, cell wall poly-saccharides and cell wall calcium fruit content were studied during ripening in two consecutive years. During harvest period pectic fractions soluble in water, carbonate and...
Quality Evaluation of ‘Sunburst’ Cherries Harvested at Different
Agulheiro-Santos, A.C.; Palma, V.; Machado, G.; Rato, A.E.; Cabrita, M.J.The sweet cherry ‘Sunburst’ is highly appreciated by consumers due to its organoleptic traits. Regional producers tend to harvest cherries sooner in order to increase their profits. With the aim of understanding the consequences of this we have tested the effect of different ripeness stages at the moment of harvesting on fruit quality. Quality parameters tested included external colour (L*, a*, b*), fruit textu...
Studies on the biodistribution of dextrin nanoparticles
Gonçalves, Clarisse; Ferreira, M. F. M.; Santos, A. C.; Prata, M. I. M.; Martins, J. A.; Geraldes, Carlos F. G. C.; Gama, F. M.The characterization of biodistribution is a central requirement in the development of biomedical applications based on the use of nanoparticles, in particular for controlled drug delivery. The blood circulation time, organ biodistribution and rate of excretion must be well characterized in the process of product development. In this work, the biodistribution of recently developed self-assembled dextrin nanopar...
Brain stem and cerebellum volumetric analysis of Machado Joseph disease patients
Camargos,S T; Marques-Jr,W; Santos,A CMachado-Joseph disease, or spinocerebellar ataxia type 3(MJD/SCA3), is the most frequent late onset spinocerebellar ataxia and results from a CAG repeat expansion in the ataxin-3 gene. Previous studies have found correlation between atrophy of cerebellum and brainstem with age and CAG repeats, although no such correlation has been found with disease duration and clinical manifestations. In this study we test th...
Anti-Leishmania titers and positive skin tests in patients cured of kala-azar
Viana,G.M.C.; Nascimento,M.D.S.B.; Diniz Neto,J.A.; Rabelo,E.M.F.; Binda Júnior,J.R.; Santos Júnior,O.M.; Santos,A.C.; Galvão,C.S.; Guimarães,R.S.Visceral leishmaniasis (VL), also known as kala-azar, is an important public health problem. If not treated, virtually all clinically symptomatic patients die within months. The diagnosis is based on the Montenegro skin test (MST) and anti-Leishmania titers. Nevertheless, the time required for cured individuals living in a leishmaniasis-endemic area to present a positive skin test and negative anti-Leishmania s...
Efeitos da inclusão de torta de macaúba sobre a população de protozoários rumin...
Rufino,L.M.A.; Barreto,S.M.P.; Duarte,E.R.; Geraseev,L.C.; Santos,A.C.R.; Jaruche,Y.G.Nesta pesquisa avaliaram-se os efeitos de diferentes níveis de inclusão da torta de macaúba (Acrocomia aculeata) sobre a população de protozoários do rúmen de caprinos. Foram utilizados oito cabritos machos castrados, sem raça definida, portadores de fístulas ruminais, dispostos em dois quadrados latinos e alimentados com quatro dietas com diferentes níveis da torta. Para quantificação dos protozoários, amostra...
