Modelling of the electron range for use of E-beam treatment for boned dry-cured hams sanitation
(Innovative Food Science and Emerging Technologies, 2023) Lucas, J.R.; Cárcel, J.A.; Velasco De Diego, Raquel; Benedito, J.; Cabeza Briales, María Concepción
The heterogeneity of the dry-cured ham size and the fat layer thickness can compromise the electron range throughout the piece and, therefore, the E-beam treatment effectiveness to guarantee its microbiological and sensory quality. The present work aimed to model the electron range in boned dry-cured ham according to the mentioned factors. For that, a dose mapping was carried out applying 2 kGy in experimental blocks manufactured with different thicknesses of lard and/or lean ham. The model, that explains 99.2% of the dose distribution variability, consisted in both a two-phase linear and a modified Gompertz functions. According to the model, the thicker the subcutaneous fat layer, the greater the electron range. The model estimated that the two-face treatment at 2 kGy on hams with a 10-mm external fat layer would be sufficient to sanitize the area of highest risk of contamination during deboning process. Industrial relevance: The export of deboned dry-cured ham to countries such as the USA and China requires the absence of Listeria monocytogenes in 25 g of product. The E-beam treatment at doses between 2 and 3 kGy provides to achieve this objective without product quality losses. The model developed in this work allows to predict the absorbed dose according to the piece size and the thickness of the subcutaneous fat layer. The results show that the distribution of the absorbed dose after bilateral treatment with 2 kGy is more uniform when the thickness of the piece is approximately 80 mm and the thickness of the fat layer is 10–30 mm. The model also makes it possible to quantify the optimal thickness of the specimen when the subcutaneous fat layer is <10 mm or >30 mm
Enrichment of dry-cured ham with a-linolenic acid and a-tocopherol by the use of linseed oil and a-tocopheryl acetate in pig diets
(Meat Science, 2008) Santos Arnaiz, Carlos; Hoz Perales, Lorenzo De La; Cambero Rodríguez, María Isabel; Cabeza Briales, María Concepción; Ordóñez Pereda, Juan Antonio
The use of α-linolenic acid and α-tocopherol enriched pork on the fatty acids and the sensory characteristics of Spanish dry-cured hams have been studied. Five batches of hams were manufactured using the posterior legs of pigs fed on diets with the same ingredients except for the oil source: sunflower (C), linseed (L) or linseed and olive (1/1, w/w, LO). Two different α-tocopheryl acetate concentrations [20 (C, L and LO) or 220 (LOE and LE)mg/kg diet] were used. Biceps femoris and Semitendinosus/Semimembranosus muscles from hams with low polyunsaturated fatty acid n-6/n-3 ratio (less than 3) were obtained from animals fed on linseed and linseed/olive oil enriched diets. However, hams from animals fed on diets added with linseed and α-tocopheryl acetate (20mg/kg diet) (batch L) were rejected by consumers because of less acceptable sensory characteristics and higher TBARs. The remaining hams had satisfactory sensory and nutritional characteristics.

La emergencia sanitaria por la pandemia COVID-19 afectó al desarrollo académico del Curso 2019-20 de tal manera que, en un periodo de tiempo escaso, las Universidades tuvieron que virar de forma urgente hacia un modelo de enseñanza-aprendizaje a distancia. Todos los planes de estudio cuidadosamente construidos cambiaron de repente hacia una docencia y una evaluación que se tuvo que desarrollar completamente en línea. La evolución de la pandemia impidió la vuelta a una enseñanza presencial completa para el Curso 2020-21 y nos obligó a plantear la docencia en un nuevo escenario semipresencial en donde el uso de herramientas virtuales para la adquisición de competencias de los estudiantes es necesario. El proyecto pretende compartir experiencias docentes y metodologías didácticas innovadoras desarrolladas por profesorado del Grado en Veterinaria que faciliten la docencia ante distintas eventualidades. Este proyecto brinda una gran oportunidad al profesorado, que tuvo que enfrentarse a una situación académica sin precedentes, para reflexionar, y detectar las debilidades del material docente que se preparó con urgencia y mejorarlas.
Use of the E-beam radiation to eliminate Listeria monocytogenes from surface mould cheese
(International Microbiology, 2015) Velasco De Diego, Raquel; Ordóñez Pereda, Juan Antonio; Cambero Rodríguez, María Isabel; Cabeza Briales, María Concepción
Camembert and Brie soft cheese varieties were subjected to E-beam irradiation as a sanitation treatment. The effects of treatments on microbiota and selected physicochemical properties were also studied. The absorbed doses required to meet the food safety objective (FSO) according to EU and USDA criteria for Listeria monocytogenes were 1.27 and 2.59 kGy, respectively. The bacterial load, mainly lactic acid bacteria, was reduced by the treatment but injured cells were recovered during storage at 14°C. The radiation treatment gave rise to negligible changes in the pH and water activity at doses required to achieve microbial safety
Effect of sanitizing E-beam treatment on the binding capacity of plasma powder used to manufacture restructured dry-cured ham models
(LWT - Food Science and Technology, 2021) Lucas, J.R.; Velasco De Diego, Raquel; García Sanz, María Luisa; Selgas Cortecero, María Dolores; Cabeza Briales, María Concepción
The manufacture of restructured dry-cured hams involves a contamination risk with pathogens such as Listeria monocytogenes. This work studied the effect of E-beam, as sanitizing treatment, on the binding capacity of plasma powder (PP). For that, model systems of restructured boneless dry-cured hams were manufactured by adapting the conventional processing of dry-cured hams to their reduced size. They were contaminated with L. innocua as a surrogate and treated bilaterally with 2 kGy. The PP binding properties were determined using tensile tests. The microstructure of the binding area was studied by scanning electron microscopy. The results showed that the binding force increased progressively with the processing time and was not modified by the irradiation treatment. Scanning electron microscopy of the binding area showed increasingly compact and dense structures probably related to changes in proteins structure induced by the treatment

Control of Listeria monocytogenes in boned dry-cured ham by E-beam treatment
(Journal of Food Safety, 2020) Lucas López, J.R.; Velasco De Diego, Raquel; Selgas Cortecero, María Dolores; García Sanz, María Luisa; Cabeza Briales, María Concepción
Boning of dry-cured hams involves additional handling which increases the risk of contamination with Listeria monocytogenes. This work studies the ability of E-beam to eliminate this pathogen from boned dry-cured ham (BDH). The destruction kinetics of four L. monocytogenes strains (S2, S4-2, S12-1, and S7-2) and L. innocua NCTC 11288 as a surrogate were determined at doses up to 3 kGy. L. innocua and L. monocytogenes S4-2 were the most radioresistant (D-value = 0.55 kGy). E-beam penetration was studied in blocks extracted from BDH and irradiated with 2–6 kGy. The bilateral treatment of 2 kGy allows the required dose (1.32 kGy) to be absorbed in the innermost part of the block to achieve the food safety objective of “zero tolerance” for this microorganism. This listericidal treatment was also confirmed in whole BDH intentionally contaminated with L. innocua. The sensory analysis of irradiated BDH showed off-odors that were imperceptible after 15 days of storage at 4ºC.
Electron spin resonance (ESR) spectroscopy study of dry-cured ham treated with E-beam
(Food Chemistry, 2012) Ordóñez Pereda, Juan Antonio; Hoz Perales, Lorenzo De La; Velasco De Diego, Raquel; Cambero Rodríguez, María Isabel; Valhondo Falcón, Margarita; Escudero Portugués, Rosa María; Cabeza Briales, María Concepción
The generation, accumulation and decay of free radicals in muscle and fat fractions from three varieties of Spanish dry-cured ham treated (0–4 kGy) in an electron accelerator have been studied by electron spin resonance (ESR) spectroscopy. In the ESR spectra from fat fractions, a well-resolved triplet signal corresponding to an alkyl radical was found only in treated samples. Linear regression models (P < 0.05) were obtained for ESR signal intensity estimation using the absorbed dose and storage time at 4 C (from 0 to 28 days). Several ESR signals were observed in the spectra from muscle fractions related to the presence of metalloprotein complexes. However, no significant (P > 0.05) differences were found between ESR spectra from untreated (0 kGy) and treated (0–4 kGy) samples. Results suggest that the analysis of ESR spectrum in fat samples can be used to evaluate the E-beam treatment of dry-cured ham
Use of the E-beam radiation to diminish the late blowing of cheese
(International Dairy Journal, 2011) Cambero Rodríguez, María Isabel; Hoz Perales, Lorenzo De La; Cabeza Briales, María Concepción; Ordóñez Pereda, Juan Antonio; Velasco De Diego, Raquel
This study examines the effect of E-beam irradiation on the survival of Clostridium tyrobutyricum to diminish the late blowing of cheese. At a dose of 3 kGy brings about a 96% reduction of the C. tyrobutyricum spores. This treatment also provokes an important reduction in the number of common microbiota presumably composed by lactic acid bacteria. Nevertheless, following reparation of damage, these bacteria still grow to reach almost normal levels. At doses lower than 3 kGy, the changes in physico-chemical and sensory characteristics of the cheese were negligible. An increase of redness (a* value) and a decrease of yellowness (b* value) were observed in irradiated samples. The irradiation at dose of 3 kGy had a significant (P < 0.05) effect on the texture, decreasing the hardness and increasing the cohesiveness. Although at 3 kGy some changes of appearance, odour and flavour were detected by sensory analysis, samples were acceptable for consumption
