Item type:Publication, Evaluación de la capacidad antioxidante en el escaldado de carambola (Averrhoa carambola L.)(2022-07-25)El escaldado es una tecnología térmica utilizada en el procesamiento de alimentos, que disminuyen el contenido de componentes bioactivos (antioxidantes), que varía según la especie, dimensión, madurez, el tiempo y temperatura a que se realice el mismo. El objetivo es evaluar el efecto de la temperatura y tiempo de escaldado sobre la capacidad antioxidante de pulpa de la carambola (Averrhoa carambola L.). La pulpa de carambola se ha obtenido de frutos colectados entre abril y mayo de 2019, del sector Centro Pastora comunidad de Tres Islas, distrito y provincia de Tambopata, Departamento de Madre de Dios, Perú, sometiendo la materia prima a temperaturas de 80, 85 y 90 ºC y tiempos de 5, 10 y 15 minutos. El análisis fitoquímico cualitativo de la fruta y pulpa, se realizó aplicando las reacciones generales de caracterización, la determinación de la capacidad antioxidante consistió en la formación del complejo azul del Fósforo-Molibdeno (V). La fruta de carambola presento abundante cantidad de compuestos fenólicos y azúcares reductores, que luego de ser sometido al proceso de escaldado presento una disminución en la cantidad de compuestos fenólicos y azúcares reductores, respecto a la capacidad antioxidante, esta pérdida de capacidad antioxidante está relacionada a la temperatura y el tiempo, a medida que aumenta la temperatura y tiempo de escaldado se produce un descenso de la capacidad antioxidante además de la variación sensorial del atributo sabor de la pulpa. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Assessment of the level of knowledge on artificial intelligence in a sample of university professors: A descriptive study(Editorial Salud, Ciencia y Tecnologia, 2024-01-01)the knowledge of artificial intelligence (AI) by university professors provides them with the ability to effectively integrate these innovative technological tools, resulting in a significant improvement in the quality of the teaching and learning process. to assess the level of knowledge about AI in a sample of Peruvian university professors. Methods: quantitative study, non-experimental design and descriptive cross-sectional type. The sample consisted of 55 university professors of both sexes who were administered a questionnaire to assess their level of knowledge about AI, which had adequate metric properties. Results: the level of knowledge about AI was low for 41,8 % of professors, regular for 40 %, and high for 18,2 %. This indicates that there is a significant gap in the knowledge of university professors about AI and its application in education, which could limit their ability to fully leverage AI tools and applications in the educational environment and could affect the quality and effectiveness of teaching. Likewise, it was determined that age and self-perception of digital competencies of professors were significantly associated with their level of knowledge about AI (p<0,05). Conclusions: peruvian university professors are characterized by presenting a low level of knowledge about AI. Therefore, it is recommended to implement training and professional development programs focused on artificial intelligence, in order to update and improve their skills in this field. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, BIOCOMERCIO Y AGROINDUSTRIA PARA LA CONSERVACIÓN AMBIENTAL EN LA AMAZONÍA(2026-01-01)The Amazon is facing a socio-environmental crisis due to deforestation, extractivism, and poor land-use planning.In response, biotrade and agribusiness have emerged as alternatives for reconciling biodiversity conservation with economic and social development.The objective of this chapter was to analyze the progress of both strategies in the Amazon based on scientific literature published between 2015 and 2026.Through a systematic review based on PRISMA 2020, open-access articles indexed in Scopus and SpringerLink were examined.The results show that biotrade and agribusiness generate income, strengthen local capacities, and promote the circular economy.However, barriers persist, such as power imbalances in supply chains, institutional weakness, territorial conflicts, technical limitations, and state absence.It is concluded that, although these initiatives are promising drivers for sustainable development in the Amazon, their scalability and equity depend on strengthening governance, inclusive public policies, innovation, and effective community participation, ensuring that regulatory frameworks or market dynamics do not exclude small-scale producers. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Factors influencing the inadequate disposal of municipal solid waste in the Peruvian Amazon(2025-12-07)The inadequate management of solid waste constitutes an environmental and public health problem of growing concern in Latin America, and the Peruvian Amazon is no exception. In cities such as Puerto Maldonado, infrastructure limitations, weak implementation of public policies, and sociocultural barriers shape waste disposal practices. This study aimed to determine the factors influencing the inadequate disposal of urban solid waste in Puerto Maldonado. A descriptive and cross-sectional design was applied to a sample of 383 inhabitants, selected through stratified sampling, using structured surveys that gathered sociodemographic data, waste management practices, and perceptions of barriers. Results showed that the lack of environmental education and awareness was the main barrier (73.4%), followed by insufficient policies and regulations (35.5%) and infrastructure deficiencies (31.9%). Moreover, only 12.8% of respondents reported the existence of recycling programs, while harmful practices such as open burning of waste persist among 37.1% of the population. Higher educational attainment was also associated with a reduction in inadequate practices, such as burning or dumping waste in unauthorized areas. It was concluded that the main factors influencing the inadequate disposal of solid waste in Puerto Maldonado are the lack of contextualized environmental education, deficiencies in basic infrastructure, and weak regulatory frameworks, which need to be strengthened to advance toward sustainable waste management.1
