Las tendencias en la alimentación han afectado negativamente el consumo de carnes rojas, responsabilizando directamente a su composición lipídica de algunas enfermedades como las cardiovasculares y el cáncer.
En el Uruguay el consumo de carnes vacunas es de 60 kg/año/persona; junto con el de la Argentina, es uno de los mayores del mundo. Su ganado es principalmente, de raza Hereford y criado en libertad, en pasturas naturales sin agroquímicos. Debido a que existen pocos estudios previos, la calidad de su carne y el contenido de su grasa intramuscular aún no son bien conocidos.
A nuestra industria ganadera le quedan muchas acciones a llevar a cabo para mejorar la calidad de las carnes, como por ejemplo la herramienta genética. Se sabe que las cruzas pueden colaborar en la obtención de terneros de crecimiento más rápido y de mejor calidad de carne y que la alimentación en pasturas (en vez de ?feed-lot?) apunta también en el mismo sentido.
El objetivo de este trabajo fue lograr, con cruzas rentables, un animal de cuatro dientes con una cobertura de grasa blanca, con una carne tierna y con un marmolado intramuscular apropiado pero también lo suficientemente magro como para que su composición grasa no influyera en la dieta. |

Ultrasound-assisted extraction (UAE) methods for food analysis are recognized as being in accordance with the principles of green analytical chemistry (GAC). Reference standard methods generally use microwave-assisted extraction (MAE) for sample digestion; however, the use of ultrasonication processes has many advantages. Herein, a simple, and economical method for the determination of Cd and Pb in fruits and vegetables for food safety monitoring is reported. This method was optimized using a standard reference material (SRM, spinach leaves) through a multivariate experimental design (optimal conditions: 0.5 g of sample, 15 min of sonication, and 20.00 mL of 2.5 mol L−1 HNO3) and subsequently validated. The limits of detection obtained were one or two orders of magnitude lower than those achieved with MAE, making this a promising technique for contaminants monitoring. The UAE method was then tested on vegetable samples (apples, carrots, tomatoes, and lettuce) obtained from commercial sources in Uruguay and a comparison was made with samples treated by MAE. Both processes yielded comparable results, and the levels of Cd and Pb in all samples were below the maximum allowed concentration (MAC) established by the World Health Organization (WHO). In addition, to provide insight into the mechanism by which the ultrasonic process aids extraction, confocal optical images of the surface of the SRM were obtained. The leaves were examined after treatment at different sonication times (5?20 min). The confocal microscopy images show the effects of the ultrasonic treatment on the plant tissue, including desaturation, erosion, and abrasion, which increased with increasing sonication time. In conclusion, the UAE method meets and overcome the requirements of a standard method for food safety assurance.
