Eighty four steers were randomly assigned to three pasture treatments with increasing levels of grain (T1: 0%; T2: 0.6%; T3: 1.2% of live weight) and to an ad libitum concentrate treatment, T4, to study the effects on carcass and meat quality. Animals were slaughtered with 500 kg of average live weight per
treatment. Average daily gain increased with increasing levels of energy, determining different slaughter dates. Intermediate treatments showed higher carcass weight than T1. T4 and T3 had a higher weight of valuable cuts than T1 and T4. Pistolas from T4 had a higher fat proportion and lower bone percentage. Increasing levels of energy in diet decreased fat yellowness. After 20 days of aging, T4 had the lowest muscle a* values and shear force was higher for T4 than for T1. With pastures finishing strategy, no adverse effects on meat quality were detected and tenderness was enhanced. |

ABSTRACT.- Vegetables are a rich source of macro and micronutrients. Particularly, potatoes and sweet potatoes are widely consumed and are two of the most important food crops in the world. Therefore, contamination of these products due to their content of inorganic contaminants is of great concern. Considering the healthy trend of consuming these tubers and roots with their skins, which are rich in fiber and other nutrients, analysis of the whole product could provide valuable information in relation to their food safety. Therefore, the presence of arsenic (As), cadmium (Cd) and lead (Pb) in peeled and whole potatoes and sweet potatoes was studied. To do so, analytical methods were optimized and validated according to the Association of Official Analytical Collaboration International (AOAC) requirements for food analysis. Although the content of As, Cd and Pb was in most cases more than three times below the maximum allowed levels for these contaminants, the presence of Cd was detected in the samples of whole sweet potato but not in the peeled ones. The same behavior was observed for Pb in most of the sweet potato samples analyzed. This information points to the need to generate information on the whole root and tuber contaminants content, and to have analytical methods available to gather data on the occurrence of these contaminants in the whole vegetable in order to perform their risk assessment according to the consumption habits. .-.-.-.-.-.-.-.-.-.-.-.--.-.-.-.-.-.-.-.-.-.-.- RESUMEN.- Los vegetales son una fuente rica en macro y micronutrientes. En particular, la papa y el boniato se consumen amplia-mente, siendo de los cultivos más importantes a nivel mundial. Por tanto, la contaminación de estos productos debido a la presencia de contaminantes inorgánicos es de gran preocupación. Considerando la creciente tendencia de consumo saludable de estos tubérculos y raíces con su cáscara, rica en fibra y otros nutrientes, el análisis del alimento entero podría brindar información valiosa con relación a su seguridad. Debido a esto, se estudió la presencia de As, Cd y Pb en papas y boniatos pelados y enteros. Para ello, se optimizaron y validaron métodos analíticos según los requerimientos de la Association of Official Analytical Collaboration International (AOAC) para análisis de alimentos. A pesar de que el contenido de arsénico (As), cadmio (Cd) y plomo (Pb) fue en la mayoría de los casos menor a un tercio de los valores máximos permitidos para estos contaminantes, la presencia de Cd se detectó en todos los boniatos enteros y no así en los pelados. El mismo comportamiento se observó para la presencia de Pb en la mayoría de las muestras de boniato analizadas.

Particularmente a batata e a batata-doce são amplamente consumidas sendo uma das culturas alimentares mais importantes do mundo. Portanto, a contaminação desses produtos pelo conteúdo de contaminantes inorgânicos é preocupante. Considerando a tendência de consumo saudável desses tubérculos e raízes com suas cascas, ricas em fibras e outros nutrientes, a análise do conjunto poderia fornecer informações valiosas em relação à sua segurança. Portanto, a presença de arsênico (As), cádmio (Cd) e chumbo (Pb) em batatas descascadas e inteiras e batata-doce foi estudada. Assim, os métodos analíticos foram otimizados e validados de acordo com os requisitos da Association of Official Analytical Colla-boration International (AOAC) para análise de alimentos. Embora o teor de As, Cd e Pb estivesse na maioria dos casos mais de três vezes abaixo dos níveis máximos permitidos estabelecidos para esses contaminantes, a presença de Cd foi detectada em todas amostras de batata-doce inteira, mas não nas descascadas. O mesmo comportamento ocorre para a presença de Pb na maioria das amostras de batata-doce analisadas. Esta informação aponta para a necessidade de gerar informação de todo o teor de contaminantes radiculares, dispor de métodos analíticos para recolher dados sobre a ocorrência destes contaminantes em toda a hortaliça realizando a sua avaliação de risco de acordo com os hábitos de consumo.
