Dry‐Cured Meat Products According to the Smoking Regime: Process Optimization t...
Fraqueza, M.J.; Laranjo, M.; Alves, S.; Fernandes, M.H; Agulheiro-Santos, A.C.; Fernandes, M.J.; Potes, M.E.; Elias, M.The manufacturing of dry‐cured meat products usually includes a smoking step. Polycyclic aromatic hydrocarbons (PAHs) are potentially carcinogenic chemical compounds that may result from smoking. The aim of the present study was to optimize the smoking regime of traditional dry‐cured meat products in order to minimize the presence of PAHs. Dry‐cured sausages were submitted to different smoking regimes: (A) no s...
Impact of a 25% salt reduction on the microbial load, texture and sensory attri...
Elias, M.; Laranjo, M.; Potes, M.E.; Agulheiro-Santos, A.C.; Fernandes, M.J.; Garcia, R.; Fraqueza, M.J.Catalão is a Portuguese dry-cured traditional sausage, highly appreciated for its distinctive sensory properties. The aim of this study was to evaluate the impact of a 25% salt reduction on Catalão manufactured with either purebred Alentejano (Al) or crossbred Iberian × Duroc (IDr) pork meat, on its physicochemical and microbiological stability, texture parameters, and sensory attributes. No significant effect ...
Shelf-life extension and quality improvement of a Portuguese traditional ready-...
Laranjo, M.; Potes, M.E.; Gomes, A.; Véstia, J.; Garcia, R.; Fernandes, M.J.; Fraqueza, M.J.; Elias, M.Cabec a de xara is a traditional ready-to-eat meat product (RTEMP) from the Portuguese region of Alentejo. It is a moulded galantine made of low value pork pieces. The aim of this work was to test the addition of vinegar in reducing the spoilage microbiota, as well as controlling Listeria monocytogenes, in order to increase the shelf-life of cabec a de xara. Physicochemical (fatty acids and biogenic amines prof...
What is the main processing factor influencing Staphylococcus species diversity...
Fraqueza, M.J.; Rocha, J.M.; Laranjo, M.; Potes, M.E.; Fialho, A.R.; Fernandes, M.J.; Fernandes, M.H.; Barreto, A.; Semedo-Lemsaddek, T.; Elias, M.The microbiota of traditional dry-cured sausages and industrial environment was assessed to characterize the diversity of coagulase-negative staphylococci (CNS), and establish potential relationships with hygiene level or technological characteristics. Eight processing units from South Portugal were audited according to a checklist of requirements. Environmental and products’ samples at different production sta...
Quality and acceptability of dry fermented sausages prepared with low value pork.
Alves, S.P.; Fernandes, M.J.; Bessa, R.J.; Laranjo, M.; Agulheiro-Santos, A.C.; Elias, M.; Fraqueza, M.J.The food industry aims to produce dry fermented sausages (DFS) with high quality, but Alentejano or Iberian pork has a high price, which might jeopardize the sustainability of traditional producers. Considering this fact, the objective of this work was to evaluate the quality and acceptability of DFS made with low value pork raw material from Alentejano purebred sows and a crossbred Iberian × Duroc pigs. The nu...
Development of a long-life vacuum-packaged ready-to-eat meat product based on a...
Laranjo, Marta; Gomes, A.; Potes, M.E.; Fernandes, M.J.; Fraqueza, M.J.; Elias, M.Carne do alguidar is a Portuguese traditional pork fried meat, usually manufactured for self-consumption purposes. This study developed a ready-to-eat (RTE) meat product, to meet today's consumers’ convenience, manufactured at the industrial scale evaluating its quality and shelf-life, assessing the effect of vacuum packaging and the use of an antioxidant (50 ppm BHT) to enhance oxidative stability. Physicochem...
Impact of salt reduction on biogenic amines, fatty acids, microbiota, texture a...
Laranjo, Marta; Gomes, A.; Agulheiro-Santos, A.C.; Potes, M.E.; Cabrita, M.J.; Garcia, R.; Rocha, J.M.; Roseiro, L.C; Fernandes, M.J.; Fraqueza, M.J.Meat industry needs to reduce salt in their products due to health issues. The present study evaluated the effect of salt reduction from 6% to 3% in two Portuguese traditional blood dry-cured sausages. Physicochemical and microbiological parameters, biogenic amines, fatty acids and texture profiles and sensory panel evaluations were considered. Differences due to salt reduction were perceptible in a faint decli...
Characterisation of "Catalão" and "Salsichão" Portuguese traditional sausages w...
Laranjo, Marta; Gomes, A.; Agulheiro-Santos, A.C.; Potes, M.E.; Cabrita, M.J.; Garcia, R.; Rocha, J.M.; Roseiro, L.C; Fernandes, M.J.; Fraqueza, M.J.The present study evaluated the effect of salt reduction on traditional dry-cured sausages' safety, quality and product acceptance, comprising physicochemical and microbiological parameters, biogenic amines, fatty acids, texture profile and sensory analysis. According to our results, salt content had a major effect on microbiological counts, although not compromising the products' safety. Marked differences wer...
Evaluation of antibiotic susceptibility of Lactobacillus plantarum isolated fro...
Chaves, A.; Fernandes, M.H.; Fernandes, M.J.; Elias, Miguel; Barreto, A.S.; Fraqueza, M.J.Nowadays the use of fermentative microbiota in food products is researched in order to confer protection to the products and furnish health benefits to consumers The aim of this work was to evaluate antibiotics susceptibility of Lactobacillus plantarum isolated from fermented traditional meat products in order to select them to be used as starters or protective bacteria on fermented meat products. The susceptib...
Selection of staphylococci strains isolated from a Portuguese traditional ferme...
Carvalho, L.; Fernandes, M.J.; Fernandes, H.; Semedo-Lemsaddek, T.; Elias, M.; Barreto, A.S.; Fraqueza, M.J.In order to evaluate its potential use as starter cultures, 104 isolates of Staphylococcus spp. were obtained from sausages and different sampling environment points in workshops A and B, at southern region of Portugal. PCR amplification was carried out to confirm genus and species allocation. From workshop A, 47 isolates were staphylococci, the majority belonging to the specie S. equorum, while from workshop B...
