Marketing and promotion strategies for meat products in most of the current export markets, mainly in those with high competitivity, have demonstrated the advantage of been based on solid scientific and technique knowledge in order to certify and assure the nourishing innocuousness, animal welfare, human health and product quality. In spite of this world tendency, in Uruguay, there is a recent concern about this matter, so there is a need of positioning Uruguayan meat products in an international context based on this modern approach. There are many different sheep production systems in the world, with very specialized lamb meat products oriented to certain niche markets. This reality is very clear in Europe, where in the Mediterranean area, young animals are produced almost at the foot of the ewe (?lechales?) with a short period of fattening under very intensive production conditions, whereas in the North Europe, lambs are produced on intensive grazing systems with strategic use of concentrates, but remarkably heavier than those coming from the South. In this sense, the average carcass weight in 2001 was 11.1, 20.1
and 21.7 kg for Spain, UK and Germany, respectively. These differences in lamb types and production systems are also associated with a high variation in both cooking and consumption habits, determining a wide range of preferences for certain type of meats and, therefore, generating some constraints in the commercial exchange (Hernando et al., 1996 and Sañudo et al., 1998). These difficulties are greater in sheep than in bovine species, given that lamb meat is more aromatic, so, it has more probability of being rejected by the most sensible consumers. There are some reasons to believe that significant differences may exist in lamb palatability attributes of different geographical sources due to variations in genetics, nutrition, slaughter weight and age, chilling rates, processing, and extent of postmortem ageing (Jeremiah, 1988). As a result, the better knowledge gathering in relation to those factors influencing the preferences of the end consumers around the world will generate more information for the future design of marketing and promoting campaigns of the Uruguayan lamb.

ABSTRACT.
The distinctive color of red grapefruits is due to lycopene, an unusual carotene in citrus. It has been observed that red ?Star Ruby? (SR) grapefruits grown inside the tree canopy develop a more intense red coloration than those exposed to higher light intensities. To investigate the effect of light on SR peel pigmentation, fruit were bagged or exposed to normal photoperiodic conditions, and changes in carotenoids, expression of carotenoid biosynthetic genes and plastid ultrastructure in the peel were analyzed. Light avoidance accelerated chlorophyll breakdown and induced carotenoid accumulation, rendering fruits with an intense coloration. Remarkably, lycopene levels in the peel of shaded fruits were 49-fold higher than in light-exposed fruit while concentrations of downstream metabolites were notably reduced, suggesting a bottleneck at the lycopene cyclization in the biosynthetic pathway. Paradoxically, this increment in carotenoids in covered fruit was not mirrored by changes in mRNA levels of carotenogenic genes, which were mostly up-regulated by light. In addition, covered fruits experienced profound changes in chromoplast differentiation, and the relative expression of genes related to chromoplast
development was enhanced. Ultrastructural analysis of plastids revealed an acceleration of chloroplasts to chromoplast transition in the peel of covered fruits concomitantly with development of lycopene crystals and plastoglobuli. In this sense, an accelerated differentiation of chromoplasts may provide biosynthetic capacity and a sink for carotenoids without involving major changes in transcript levels of carotenogenic genes. Light signals seem to regulate carotenoid accumulation at the molecular and structural level by
influencing both biosynthetic capacity and sink strength.
