Colorantes alimentarios y su relación con la salud: ¿cómo abordar esta problemática desde el estudio de las disoluciones?

Abstract

Studies have shown that adolescents, for the most part, frequently consume considerable amounts of drinks based on powdered juices which contain food dyes potentially harmful to health. In this sense, this problem is addressed from the study of dissolutions. The didactic proposal in context was carried out with second year students of secondary education with the objective not only of working on the curricular theme, but also with the intention of contributing to education for health and to the awareness of young people in their role of consumers. Through the contextualized work and the proposed theoretical-practical activities, the approach of the dissolutions theme was achieved by considering the study of the food dyes present in powdered juices and their relationship with health. The applied methodological strategy was useful to overcome the difficulties that students usually manifest when dealing with the topic of dissolutions and to emphasize the importance of experimental work and contextualization.
