Researchers of the UNL evaluate how to make the most of peaches and citrics from Santa Fe to elaborate juices and nectars. Besides, they test the addition of whey to enhance its nutritional properties. In order to throw away the idea that what is not fresh is not good the specialists say that the fact of taking advantage of fruit’s discards would enable produced food to have a lower economic value to the final market. The research points to physical-chemical, microbiological, mineral quality and the acceptability of the products.
En forma conjunta con la Academia de Ciencias de Bulgaria, científicos de la UNLP proyectan monitorear los niveles de radiación que reciben los vuelos a partir de la colocación de un dosímetro de radiación cósmica solar en el satélite argentino SAC “D”. En nuestro país se realizan vuelos últra prolongados de más de 13 horas en rutas transpolares, lo que somete al pasaje a un mayor riesgo de recibir radiaciones cósmicas. La exposición a la radiación cósmica afecta al genoma humano. Los efectos más usuales son la aparición de tumores y las alteraciones genéticas.
