Pisco grapes are 8 known varieties of Vitis vinifera from which pisco is obtained during the pisco production process, by-products such as seeds, skins and others are released from the fruit; the seeds are lately becoming especially important due to their high content of polyphenols and their antioxidant properties. There are several methods for obtaining extracts and in order to obtain extracts with the highest possible polyphenol content in this study, an ultrasonic bath with a solvent system ethanol: water: acetic acid (90/9.5/0.5) is used, which is then taken to dryness in a rotary evaporator. The Total Polyphenols index was determined to be between 402 to 84 μg of seed, flavonoid compound index of 9 to 42 μg of seed; the antioxidant activity by the DPPH method expressed as IC50 between 0.184 to 0.858 mg of extract and by the FRAP method expressed as mM equivalent of trolox from 0....

The Zea mays purple variety is a plant native to America that has purple grain and crown, thanks to the anthocyanins that are the pigments that give this color. The objective of this work was to analyze the influence of the various drying procedures of the purple maize carried out by the producers of the Ica valley, on the proximal chemical composition and the content of total anthocyanins. 5 drying procedures were applied, which were coded from T1 to T5 and the coronas and grains were analyzed separately; it is observed that the different treatments do not significantly affect the chemical composition of the crown or the grain; however, treatments 3 and 4 preserved a higher content of anthocyanins in the crown (1513 and 1516 mg / 100g), while treatment 2 preserved a higher content of anthocyanin in the grain (907,1 mg / 100g).

Polyphenols are compounds of secondary metabolism in plants and their action is recognized in the control against free radicals and reactive oxygen species. Th e study aimed to indicate polyphenols and their intake in fruits and vegetables as a protective action for human health due to stress against Covid-19. Given the rapid spread of the emerging pandemic Covid-19, it continues to be of great concern due to the mortality that occurs globally and there is no doubt about the level of stress in the population. Attempts to fl atten the epidemiological curve are diverse in that Covid-19 could not only aff ect psycho-mentally, but some non-communicable diseases may perhaps debut. Considering the serious situation, from the axiological point of view, a question arises: can the daily consumption of fruits and vegetables in the diet patterns generate, from the metabolic point of view, any poten...

El propósito del trabajo fue analizar las tecnologías de la información y comunicaciones en el proceso enseñanza–aprendizaje universitario como progreso educativo. Se indicó cómo se acrecienta el conocimiento tanto en los docentes y alumnos mediante el uso aplicativo de las tecnologías de la información y comunicaciones (TIC). Asimismo, se destacó la necesidad de los docentes en mantener capacitaciones de forma sistemáticas para el uso de las TIC en aula y lo que representa como mecanismo de integración para la formación profesional. Finalmente, se describe la creación de habilidades binomiales entre docentes-estudiantes que posibilitan modificar el enfoque tradicional por enfoque de competencia durante la nueva enseñanza del siglo XXI.

The aim of the study was to describe theoretical-practical tools of the professional teaching and learning process as a category of university teaching. The study was carried out from January to June 2021, where teaching was considered as the first university mission, the category that refers to the professional process of teaching and learning. In this category, six theoreticalpractical tools are mentioned: 1st) establishes the didactic strategies, 2nd) selects the content, 3rd) identifies the learning resources, 4th) schedules the activities, 5th), considers the type of evaluation, and 6th) the learning outcome is diagnostic and then conceptualized for description. It is indicated that every process aims to optimize methods and techniques in the teaching and learning relationship to move between skill levels. In the process of updating and relevancy of knowledge, a definition of the pr...

The aim of the study was to analyze the educational training, research and innovation in university teachers through a contemporary critical precept. Indicates that the social dynamics is based on patterns and analytical indicators of changes, experiences of the actors involved, in addition to the evaluative criterion by specialists in the type of method and creation of theories about the practices accumulated during the events of phenomena, processes, events or relevant events such as the demonstration of assumptions. Educational training, research and innovation in university teachers require exhaustive behaviors and deep critical reflection during the evaluative construction of facts and transmission of true knowledge that are acceptable to society, demonstrating social changes in the way of thinking and acting. Keywords: competence model – educational thinking – professional comp...

El objetivo del estudio fue analizar la formación educativa, investigación e innovación en docentes universitarios mediante un precepto crítico contemporáneo. Se indica que, la dinámica social está sustentada sobre patrones e indicadores analíticos de cambios, experiencias de actores involucrados, además, del criterio valorativo por parte de especialistas en el tipo de método y creación de teorías sobre las prácticas acumuladas durante los acontecimientos de fenómenos, procesos, sucesos o eventos que resultan relevantes como la demostración de supuestos. La formación educativa, investigación e innovación en docentes universitarios requiere de comportamientos exhaustivos y reflexión crítica profunda durante la construcción evaluativa de hechos y trasmisión de verdaderos conocimientos que sean aceptables para la sociedad demostrando, cambios sociales en la manera de p...
