Para lograr el objetivo propuesto inicialmente y para dar respuesta a la pregunta de estudio, se creó una unidad didáctica compuesta por diferentes artículos científicos dos últimos cinco años que abordan el conjunto de la N&N. El trabajo fue realizado durante el año lectivo 2022 en forma presencial para alumnos de secundaria de la Institución Educativa SESI (Servicio Social de la Industria), unidad Gama, del Distrito Federal de Brasília - Brasil, mediante una secuencia de sesiones de 5 horas semanales dentro de un eje formativo (Módulo Itinerario de Ciencias de la Naturaleza).\u0000\u0000Descriptores: Nanociencia, nanotecnología, difusión científica, alfabetización científica.\u0000\u0000Abstract\u0000\u0000Nanoscience and Nanotechnology (N&N) are increasingly part of our daily lives, their applications are highlighted in various scientific and technological areas. The integration of this subject in education allows the development of interdisciplinary approaches in a variety of subjects, as well as the insertion of the student population of schools as part of these scientific advances. The objective of this work was to understand the interpretations of high school students, made from popular science texts on N&N in natural science classes, giving greater emphasis to the discipline of Physics, verifying some limits and possibilities of these readings, focusing on the study question posed: How do students produce significant results from reading popular science texts related to nanoscience and nanotechnology? To achieve the initially proposed objective and to answer the study question, a didactic unit was created consisting of different scientific articles two of the last five years that address the N&N set. The work was carried out during the 2022 school year in person for high school students of the SESI Educational Institution (Industry Social Service), Gama unit, in the Federal District of Brasilia - Brasil, through a sequence of 5-hour weekly sessions within a training axis (Science Itinerary Module of the nature).\u0000\u0000Keywords: Nanoscience, nanot","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"22 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83156837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FTIR - ATR strong absorption signals at different values of vibration frequencies (cm-1) that correspond to functional groups of anthocyanins. The highest value in CAT corresponds to the extract of alaybili and the lowest to the condorusa with 108.12 and 56.07 (mg of cyanidin 3-glucoside / 100 g of fresh weight) respectively. Similarly, the highest value in PFT corresponds to alaybili and the lowest to condorusa with 627.13 and 342.24 (mg of gallic acid / 100 g of fresh weight) respectively. Therefore, it is concluded that the extracts of these fruits can be a source of functional foods as natural colorants in the food industry due to their high content of antioxidants.\u0000\u0000Keywords: Anthocyanins, Polyphenols, Antioxidants, Free Radicals, Flavonoids","PeriodicalId":21546,"journal":{"name":"Revista ECIPeru","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81331390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
