A “Calçadinha” de S. Brás de Alportel e a Antiga Rede Viária do Algarve Central
A obra que tivemos ensejo de ler constitui um dos mais recentes trabalhos de investigação sobre as vias romanas da região algarvia.
Com efeito, trata-se de um projecto iniciado em 1999, mas que apenas foi trazido “à luz” em Junho de 2002, graças a esforços conjuntos entre a autarquia de S. Brás de Alportel e o Departamento de História e Arqueologia da Universidade do Algarve.
Digna de destaque afigura-se-nos também a ambivalência do tema que, pelo seu carácter cumulativo, suscitou a intervenção de autores cujo domínio do saber abrange as épocas romana e medieval, contribuindo assim para invalescer a pertinência deste trabalho
As vias romanas do Algarve
O presente trabalho aborda o estudo da rede viária romana do Algarve (itinerários principais) que, até à data, não havia sido alvo preferencial de investigação exaustiva.
Procurámos estabelecer o traçado viário do litoral, tentando definir as vias que, partindo do eixo costeiro, se dirigiam para norte através das serras e do barrocal, focando a rede de povoamento que àquele estava associado. Cremos que a articulação da rede viária com o povoamento e as mútuas influências daí decorrentes, questão que procurámos desenvolver, poderá posteriormente abrir novas perspectivas a futuros trabalhos de investigação.
Abordámos também os aspectos económico - políticos directamente afectos às necessidades de construção e manutenção viária. Por último, e devido ao facto de considerarmos os traçados viários autênticos palimpsestos, fizemos, necessariamente, uma alusão aos troços de estradas medievais e mesmo posteriores, ainda que não profundando a questão exaustivamente, já que tal ultrapassaria os objectivos deste trabalho
Effect of sex and carcass weight on sensory quality of goat meat of Cabrito Transmontano
The main purpose of this work was
the characterization of Cabrito Transmontana goat kid
carcass and meat, which is a Protected Origin Designation
product. The effects of sex and carcass weight
were studied. Sensory attributes of toughness, juiciness,
flavor intensity, flavor quality, odor intensity, fiber presence
(stringy), sweet intensity, and overall acceptability
were evaluated in 60 males and females allocated to 3
carcass weight groups: 4, 6, and 8 kg. Sensory quality
of meat was evaluated by a trained taste panel of 11 experts
in 5 sessions. Generalized Procrustes analysis was
performed, and 93% of total variability was explained
by the 2 first factors (axes). Correlation between sensory
traits and factors 1 and 2 allowed the factors to
be renamed as toughness/aroma and juiciness/acceptability,
respectively. Procrustes analysis indicated that
a sex effect was detected by experts. Meat from males
presented greater juiciness, flavor quality, and general
acceptability than did meat from females. Cabrito
Transmontano Protected Origin Designation includes
animals from 4 to 9 kg of carcass weight. However, differences
among them can be important, because the
taste panel found differences between animals from distinct
carcass weight ranges. Lighter weight carcasses
were considered more tender with less flavor and odor
intensity than heavier carcasses
New sheep and goat products: “Mantas” and sausages. An integrated project in co-promotion.
A project between a research centre, two breeder associations and a meat manufacturing industry was developed to add value to animals with very low commercial acceptability, creating two new products,
a raw fresh meat sausage and a processed meat product "mania". The ratio between MUFA+PUFAISFA was 1.54 g/100 9 and 1.55 g/100 g of dry product and protein percentage 17.8%, and 18.8% for ewe and goat sausages, respectively. The most abundant unsaturated fatty acid was the C 18:1 and protein was 44.5 and
51% for ewe and goat mantas, respectively. Both are balanced products in protein and fat contents resulting in an interesting solution to give added value to animals with very low commercial price.The authors thank the PROOER, Medida 4.1 Cooperaão para a lnovação for funding the research

Sensory quality evaluation of Serrana Kids meat: effect of sex and carcass weight
The main purpose of this work is the characterization of Serrana kids carcass and meat, which
is a Protected Origin Denomination product. The effects of sex and carcass weight were studied.
Parameters of toughness, juiciness, flavour intensity, flavour quality, odour intensity, fibre presence,
sweet intensity and overall acceptability were evaluated on sixty males and females allocated to
3 carcass weight groups: 4, 6 and 8 kg. Sensory quality of meal was evaluated by a trained taste
panel of 11 experts in five sessions. Meat was previously cooked in a conventional oven until
inner temperature reached 70/S00C. Then it was cut in sample pieces of2*2*0.5 cm and given to
the pane l members to be evaluated following a standard methodology
Effect of breed and sex on pork meat sensory evaluation
This work had an objective to evaluate the sensory quality of two categories of pork meat from a
commercial pork meat and a selected meat from the Portuguese black pork (Preto Alentejano
breed). Sixteen animals were used, 8 females and 8 males from each breed. Animals had 80 - 100
kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar
vertebra was used in the analysis. Sensory analysis was performed by a trained taste panel of 10
elements, in 5 sessions. All evaluation conditions were standardized, and the attributes studied
were odor intensity, toughness, juiciness and flavor intensity. The taste panel found differences
mainly between breeds. The panellists scored Preto Alentejano meat as being juicier, tenderer,
and with richer taste than Commercial meat. The higher juiciness score of Preto Alentejano meat
was probably attributable to the higher intramuscular fat content compared with Commercial
meat. The Commercial pork was characterized mainly by high toughness.info:eu-repo/semantics/publishedVersio
Pork meat quality of Preto Alentejano and commercial largewhite landrace cross
This work aimed to evaluate the physical-chemical characteristics of pork from a local breed (Portuguese black pork called
Preto Alentejano) and a commercial breed. Sixteen animals were used, 4 females and 4 males from each breed. Animals
had 80-100 kg of live weight. The longissimus muscle between the 5th thoracic vertebra and the 10th lumbar vertebra was
used in the analysis. Samples were analysed for protein, fat, pigments, ashes, dry mater, water-holding capacity, and texture. Results of fat and pigments contents indicate significant (P<0.05 and P<0.01) differences for all treatments. For protein,
ashes, dry mater, water-holding capacity and texture, no significant differences were found for sex. In the analysis of fatty
acids composition, ten were detected, being the main ones C16:0, C18:0, C16:1, C18:1, C18:2. There was a predominance of
monounsaturated fatty acids (MUFA), followed by saturated (SFA) and polyunsaturated (PUFA). Differences were significant
for sex (P<0.01) and breed (P<0.01). Preto Alentejano breed and females presented the higher percentages of SFA (P<0.01)
and MUFA (P<0.001) fatty acids. Differences between breeds might be due to breed production system and feed differences
BISIPORC – Extensive production of Bísaro pigs in two alternative systems: fattening with concentrate vs. chestnut. Preliminary results of carcass and meat characteristics
A produção de porco da raça Bísara – pese embora o cada vez mais importante papel que esta representa no Norte
de Portugal, principalmente nas explorações familiares do Nordeste transmontano – o conhecimento do seu sistema
de exploração, do maneio alimentar, da utilização de recursos alimentares da região e sua influência na qualidade
do produto final, do controle e factores que influenciam o crescimento e desenvolvimento corporal, da qualidade das
carcaças e da carne produzida e logicamente as aptidões da sua carne à transformação tecnológica – é ainda incipiente.
Assim, o conhecimento cabal dos sistemas de produção, nas suas diversas componentes, é de fundamental interesse,
para garantir a obtenção de produtos que correspondam às exigências desde a transformação ao consumidor. Neste
sentido, o principal objetivo do projeto BISIPORC foi estudar a produção de porcos da raça Bísara em regime extensivo
de pastoreio e acabados em dois sistemas alternativos: Engorda e acabamento com concentrado específico; Engorda e
acabamento com concentrado específico e castanha.
São apresentados os primeiros resultados de características das suas carcaças, características físico-químicas e sensoriais
da sua carnePork production of Bísaro breed – despite the increasingly important role it plays in northern Portugal, especially in family
farms of transmontano Northeast – the knowledge of production system, food management, use of regional food resources
and its influence on the final product quality, control and factors that influence growth and body development, quality of
carcasses and meat produced and of course the skills of their meat to the technological transformation – is still incipient.
Thus, the exact knowledge of production systems in its different components is of fundamental interest to ensure the
production of products which meet the requirements from the processing to the consumer. In this sense, the main objective
of BISIPORC project was to study the production of Bísaro breed pigs in extensive grazing and finished in two alternative
systems: Fattening and finishing with a specific concentrate; Fattening and finishing with specific concentrate and chestnut.

A avaliação sensorial de produtos cárneos de porco Bísaro
O objectivo deste trabalho foi a caracterização sensorial da carne e produtos transformados de porco Bísaro. Esta caracterização
foi feita por um painel de provadores treinado que avaliou através de uma análise descritiva quantitativa
atributos objectivos dos produtos em análise, e por um painel de consumidores que avaliou o nível de agrado por cada
um dos produtos. Os procedimentos foram feitos de acordo com as Normas Portuguesas.
Os resultados da avaliação pelo painel de provadores indicaram que a carne de porco Bísaro tem excelentes qualidades
organolépticas. É uma carne clara, com sabores e odores moderadamente intensos, bastante tenra e suculenta.
Os consumidores consideraram os produtos avaliados agradáveis a bastante agradáveis. Destacaram o cachaço,
considerando-o muito agradável. O cachaço, produto curado, foi pontuado pelo painel de provadores como tenro e
suculento.The objective of this study was to characterize the sensory quality of Bísaro pork meat and meat products. This characterization
was performed by a trained taste panel that evaluated through a descriptive quantitative analysis specific
attributes of the products under study, and a consumer’s panel who evaluated the level of satisfaction for each of the
products. The procedures were performed according to the Portuguese standards.
The results from the taste panel indicated that the Bísaro pork meat has excellent organoleptic qualities. It is a light meat,
with moderately intense flavors and odors, very tender and juicy.
Consumers considered the evaluated products as pleasant and fairy pleasant. They highlighted the “cachaço”, considering
it very pleasant. The “cachaço”, a cured product, was punctuated by the taste panel as tender and juicy.Os resultados apresentados são relativos ao
