RESUMO
Resumen Los edulcorantes no calóricos representan una buena alternativa para sustituir los sabores dulces sin la respuesta fisiológica que genera el consumo de azúcares. Por sí solos no son herramientas para el control de peso. Su consumo debe ir acompañado de una dieta correcta y un estilo de vida saludable que incluya actividad física. Su utilidad radica en proporcionar el agradable sabor dulce sin el aporte energético. La inocuidad de cada uno de los compuestos aprobados está comprobada y se reevalúa constantemente para tomar en cuenta los resultados de nuevos estudios. Debido a que no existe un edulcorante perfecto, la variedad ayuda a que se desarrollen productos cada vez más agradables para el consumidor. Este trabajo es fruto de una revisión exhaustiva de la bibliografía y de las discusiones de un panel de expertos de diversas especialidades: toxicología, ginecoobstetricia, pediatría, endocrinología, nutrición, medicina interna, salud pública y medicina preventiva, en el que se analizó extensamente la bibliografía se revisó una variedad de trabajos científicos que responden a las interrogantes que habitualmente se hacen los profesionales de la salud acerca de seguridad en diferentes grupos etáreos y con afecciones específicas, ingestión diaria admisible, etc.
Abstract Non-caloric sweeteners are a good alternative to replace the sweet flavors without the physiological response generated by the consumption of sugars. Alone they are not tools for weight control. Its intake must be accompanied by a proper diet and a healthy lifestyle that includes physical activity. Its usefulness lies in providing a pleasant sweet taste without the energy intake. The safety of each of the compounds is tested and approved and constantly reassessed to take into account the results of new studies. Since there is no perfect sweetener, variety helps that more and more pleasing to the consumer products are developed. This work is the result of a comprehensive review of the literature and discussions of a panel of experts from various specialties: toxicology, obstetrics and gynecology, pediatrics, endocrinology, nutrition, internal medicine, public health and preventive medicine, where literature was widely analyzed reviewing a variety of scientific papers that address the questions that usually are made by health professionals on safety in different age groups and with specific diseases, acceptable daily intake, etc.
RESUMO
Pacific white shrimp were fed diets containing natural pigments from Aztec marigold (Tagetes erecta) petals extracts (esterified and saponified). The pigmenting effect of these carotenoid free control diet and a synthetic astaxanthin (Roche Carophyll Pink) supplemented diet. It was found that after 14 days of feeding, the shrimp showed that the saponified marigold extract and the high concentration esterified marigold extract supplemented dists produced a better pigmentation effect (between 50-70) in the exoskeleton than the astaxanthin, the low concentration esterified marigold extract and the basal diets, the latter diets being non-significanthy different among themselves. However, during the same 14 day period, non-significanthy different results were observed in the carotenoid content of the shrimp abdominal muscle when fed with all diets except the low concentration esterified marigold extract diet that showed a significanthy lower value than the saponified marigold extract diet. These results indicate that the main caroteid sources in Tagetes erecta, namely lutein and zeaxanthin, are possibly metabolized into astaxanthin and deposited by the Pacific white shrimp
