Rabbit meat usage in processed products is low. However, rabbit meat raw sausage can be an alternative to increase this meat’s market share. The objective of this study was to determine the effect of blending textured soybean protein and rabbit meat on the texture profile analysis and sensory properties of the chorizo. Five treatments were designed, one control and another four using blends of rabbit meat and textured soybean in ratios of 10, 20, 30 and 40%. Measurements were water activity, texture profile analysis, and color, while a sensory test was conducted at the end of experiments for four treatments. The main results indicate that Aw and pH values decreased (p< 0.05), while b* value increased with storage time (p<0.05). L* value decreased after 7 d vacuum packing, but then increased after 14 d. Treatment with 20% of textured soybean results in less hardness and more springiness. Sensory analysis indicates that there is not significant difference in odor global appearance in all treatments (p>0.05), but color, hardness and taste were different (p<0.05). In conclusion, textured soybean protein can be blended with rabbit meat for processing chorizo. The meat product obtained has sensorial characteristics, a texture profile, Aw and color acceptable for this kind of raw sausage, especially in blends with 20 and 30% of textured soybean protein. Moreover, the blend of these two meat ingredients improved nutritional properties and could therefore be offering as a functional meat product.

The objective of the study was to evaluate the effects of sire breed (Charollais, Dorset and Texel), utilizing Hampshire ewes, lamb sex and birth type, on carcass traits of the lambs. After weaning (74±8 d), 45 lambs from these crosses were fattened during 63 d, consuming a balanced diet with 14% CP and 2.82 Mcal of ME/kg of DM. Lambs were weighed and slaughtered at 137 d of age; later, measures on slaughter weight and yield of hot and cold carcass, rib eye area, subcutaneous fat, carcass length, leg length, and rump perimeter were taken and the carcass compactness index was calculated. In addition, the carcass regional composition (shoulder, chest-belly, anterior-loin, leg, neck, and rear-loin) was determined. Data were analyzed utilizing a mixed model. Charollais-sired lambs had the highest (P<0.05) rib eye area (20.1±0.5 cm 2 ), while Dorset-sired lambs were superior (P<0.05) in carcass length (66.3±0.9 cm) and leg length (34.8±0.3 cm). Ram lambs surpassed ewe lambs (P<0.05) in most traits analyzed. Lambs born as singles had higher means than twin lambs (P<0.05) in subcutaneous fat and leg length. In general, crosses with Charollais and Dorset showed superiority in carcass traits.

El pan tipo pambazo es utilizado para la elaboración de un antojito mexicano típico de la zona centro de México. El componente más importante y del cual deriva su nombre, es el pan, el cual entre los parámetros de calidad más representativos debe tener un ligero sabor dulce que contrarresta con la sal, además de ser un producto muy suave y que además tenga cierta resistencia al momento de ser rellenado y dorado en la plancha. En le presente trabajo se elaboraron tres formulaciones de pan tipo pambazo, tomando una estándar como control y las otras dos fueron adicionadas con puré de papa (Solanum tuberosum) al 30% en base harina y puré de papa roja (Oxalis tuberosa) al 35 % en la elaboración de la masa. El objetivo fue evaluar la suavidad y esponjosidad de las distintas formulaciones mediante análisis de perfil de textura APT (Análisis de perfil de textura), haciendo énfasis en la dureza y por otra parte mediante evaluación sensorial con una prueba de comparaciones múltiples. Los resultados obtenidos por ambas pruebas muestran que la adición de puré de papa (Solanum tuberosum) o papa roja (Oxalis tuberosa) en la masa para la elaboración de pan tipo pambazo aumenta la suavidad del producto final. Este efecto puede ser debido a la retención de agua de los almidones de los tubérculos al momento de la elaboración del puré lo que promueve una mayor humedad en el producto final.
