Use of Black Pepper Essential Oil to Produce a Healthier Chicken Pâté
Rodrigues, Sandra; Leite, Ana; Vasconcelos, Lia; Pereira, Etelvina; Seixas, Natália; Estevinho, Letícia M.; Teixeira, AlfredoThis study aims to explore the effect of using black pepper essential oil (BPEO) to produce a healthier chicken pâté. Four different formulations were produced: a control formulation without back pepper and three with increasing BPEO contents. To test the effect of using BPEO, physiochemical analyses were performed at two different moments, 8 and 21 days after production. Microbiological analyses were performed...
Contribution to Characterizing the Meat Quality of Protected Designation of Ori...
Vasconcelos, Lia; Dias, L.G.; Leite, Ana; Pereira, Etelvina; Silva, Severiano; Ferreira, Iasmin; Mateo, Javier; Rodrigues, Sandra; Teixeira, AlfredoThe aims of this study were to describe and compare the meat quality characteristics of male and female kids from the "Serrana" and "Preta de Montesinho" breeds certified as "Cabrito Transmontano" and reinforce the performance of near-infrared reflectance (NIR) spectra in predicting these quality characteristics and discriminating among breeds. Samples of Longissimus thoracis (n = 32; sixteen per breed; eight m...
Effect of Olive Cake in Bísaro Pig Feed on Physicochemical Composition and Fatt...
Leite, Ana; Vasconcelos, Lia; Rodrigues, Sandra; Pereira, Etelvina; Domínguez, Rubén; Lorenzo, José M.; Teixeira, AlfredoThe purpose of this study was to assess the following effects: (1) the inclusion of olive in the animal’s diet on the dry-cured shoulder; (2) the effect of curing on three different muscles (infraspinatus, supraspinatus, and subscapular); (3) the effect of different curing times (fresh shoulder, 6 months curing, and 12 months curing). For this purpose, forty shoulders were used, followed by a cold nitrite-free ...
SVM regression to assess meat characteristics of bisaro pig loins using nirs me...
Vasconcelos, Lia; Dias, L.G.; Leite, Ana; Ferreira, Iasmin da Silva; Pereira, Etelvina; Silva, Severiano; Rodrigues, Sandra; Teixeira, AlfredoThis study evaluates the ability of the near infrared reflectance spectroscopy (NIRS) to estimate the aW, protein, moisture, ash, fat, collagen, texture, pigments, and WHC in the Longissimus thoracis et lumborum (LTL) of Bisaro pig. Samples (n = 40) of the LTL muscle were minced and scanned in an FT-NIR MasterTM N500 (BuCHI) over a NIR spectral range of 4000-10,000 cm(-1) with a resolution of 4 cm(-1). The PLS ...
Can near-infrared spectroscopy replace a panel of tasters in sensory analysis o...
Vasconcelos, Lia; Dias, L.G.; Leite, Ana; Ferreira, Iasmin da Silva; Pereira, Etelvina; Bona, Evandro; Mateo, Javier; Rodrigues, SandraThis study involved a comprehensive examination of sensory attributes in dry-cured Bísaro loins, including odor, androsterone, scatol, lean color, fat color, hardness, juiciness, chewiness, flavor intensity and flavor persistence. An analysis of 40 samples revealed a wide variation in these attributes, ensuring a robust margin for multivariate calibration purposes. The respective near-infrared (NIR) spectra unv...
Did the addition of olive cakes obtained by different methods of oil extraction...
Leite, Ana; Vasconcelos, Lia; Ferreira, Iasmin da Silva; Dominguez, Rubén; Pateiro, Mirian; Rodrigues, Sandra; Pereira, Etelvina; Campagnol, Paulo C.B.This study was conducted to determine the effects of different types of olive cake in the basal diet of Bisaro pigs on the volatile compounds and sensory characteristics of dry-cured loin and "cachaco". A total of 40 Bisaro breed animals were allocated to four treatments, along with a control group (T1-control, T2-crude olive cake, T3-centrifugation two phases, T4-exhausted, and T5-exhausted with 1% of olive). ...
Effect of the inclusion of olive cake in the diet on the physicochemical charac...
Leite, Ana; Vasconcelos, Lia; Ferreira, Iasmin da Silva; Dominguez, Rubén; Pereira, Etelvina; Rodrigues, Sandra; Lorenzo, José M.; Teixeira, AlfredoThe purpose of the present study was to characterize the dry-cured loin and dry-cured "cachaco" of Bisaro pork and evaluate the effect of the inclusion of olive cake in the animals' diet on the cured products. For this purpose, forty loins and forty "cachacos" were used, followed by a process of cold curing with controlled ventilation, without adding nitrites or synthetic additives. The dry-cured loin and "cach...
Novel approaches to improve meat products' healthy characteristics: a review on...
Rodrigues, Sandra; Vasconcelos, Lia; Leite, Ana; Ferreira, Iasmin da Silva; Pereira, Etelvina; Teixeira, AlfredoMeat products are a staple of many diets around the world, but they have been subject to criticism due to their potential negative impact on human health. In recent years, there has been a growing interest in developing novel approaches to improve the healthy characteristics of meat products, with a particular focus on reducing the levels of harmful salts, lipids, and nitrites. This review aims to provide an ov...
Utilização de bagaço de azeitona na alimentação de porcos Bísaro. Efeito nas ca...
Rodrigues, Sandra; Vasconcelos, Lia; Leite, Ana; Ferreira, Iasmin da Silva; Pereira, Etelvina; Teixeira, AlfredoA indústria extrativa do azeite produz grandes quantidades de subprodutos, com elevado impacto ambiental negativo, o mais relevante é o bagaço (BG) de azeitona, que pode ser mais ou menos ecologicamente prejudicial, dependendo do tipo de extração. Dentre as alternativas para usar este subproduto e aliviar o seu impacto, existe a alimentação animal, nomeadamente de porcos. Com objetivo de verificar como a alimen...
Effect of gender, castration, and diet on sensory characteristics of pork dry c...
Rodrigues, Sandra; Vasconcelos, Lia; Pereira, Etelvina; Leite, Ana; Ferreira, Iasmin da Silva; Teixeira, Alfredo; Álvarez-Rodríguez, JavierThe sensory characteristics from pork dry-cured loins from immunocastrated females (F), surgically castrated males (CM), immunocastrated males (IM), fed with peas (P), or soybean meal (S) as the main dietary source of crude protein, were compared.
