Beef aging is a process that involves the interaction of enzymes and chemical transformations that directly influence changes in flavor and texture, which in turn can determine the sensory experience for guests. The purpose of this study was to compare, in terms of texture, the aging of beef brisket cuts through two techniques: with animal fat coating and dry aging, over a period of 21 days, and to determine the acceptability of end consumers. The cuts were stored under controlled temperature and moisture conditions (2 °C and 60 % relative moisture, respectively), with continuous monitoring to ensure food safety. Finally, they were cut into 2 cm thick steaks, fried to medium doneness with salt, and sensorially evaluated by a panel of 27 individuals. The results revealed an acceptance rate of 74.1 % for the meat sample aged with animal fat, surpassing the dry-aged sample (22.3 %) and the...

Cocoa in grain is a tropical fruit considered as a heritage in Ecuador and constitutes 60% of the premium quality in chocolates worldwide, has sensory characteristics unmatched by other producing countries. Manual drying and selection activities contain many occupational hazards, affecting the safety and well-being of the people involved in these tasks, with the ergonomic risk of an intolerable level requiring immediate intervention. This research provides safe automated mechanisms for operations through internationally validated methodologies, without affecting the sensory characteristics.

The objective of this work is the design of a prototype of a pneumatic centrifugal concentrator that allows small-scale mining that takes place in desert and isolated places, to process ultrafine gold minerals in situ, cleanly, without the use of water and chemical reagents. A mathematical model based on the physico-phenomenological analysis of the differential sedimentation separation mechanism was applied in a film of laminar flow fluid, to determine the particle trajectory inside the bowl of the centrifugal concentrator as a function of the variables of bowl geometry, operating variables and physical characteristics of the particle and fluid. The simulations carried out showed a remarkable effect of the use of air instead of water on the trajectory of the particles within the fluid film. The results also showed that the capacity of the concentrator for the separation of particles by d...

The investigation concerns landscape fragmentation district of Las Lomas in Piura, affected by the existence of an open dump. The study focuses on the possible restoration of the landscape during the decommissioning process. To which we studied the native plant species of dry forest piurano selecting the most resistant and helpful in the recovery process, the same that were placed scenically on the final cover. This process called phytoremediation help the roots of trees and shrubs stabilize the closed area, degrade and absorb waste leachate. Proper placement and subsequent vegetation growth recover the landscape will help the return of displaced wildlife and allow this process to accelerate regenerator for the welfare of the surrounding population.

In the drying process of activated clay there are two important methods that can be used to dry this activated clay: Rotator continuous drying and drying atomization. But to determine the characteristics and mechanism which intervene in the drying of clay is fundamental to use a batch tray drying. The objective of the present work is obtain the curve of drying velocity, fixing sorne initial conditions of humidity, and to define the mechanisms involved in the drying of activated clay with sulphuric acid. Further, this information will be used to scale to continuous drying and find out the equations which govern this process. It was necessary to use a tray of 214 cm2 surface area to charge moist bentonite. Samples were taken containing between 48 and 138 g, and initial humidity between 38 and 50%; to achieve a.final humidity of between about 8 and 13%. Graph of clay total mass (MT) versus ...

La pitajaya (Selenicereus megalanthus) es una fruta exótica que se encuentra en las selvas amazónicas, en el caso de Perú, se encuentra con mayor frecuencia en la selva alta. Se caracteriza por tener alto contenido de vitamina C y antioxidantes, lo que la hace apetecible de ser comercializada. Respecto a su procesamiento, este debe ser realizado cerca a la fuente de materias primas, para reducir los costos que se generen. Por el tipo de fruta, no cabe duda que ya procesado puede ser considerado una oportunidad para los pueblos amazónicos eleven su nivel de vida comercializando la pitajaya.

Aunque las señales electromiográficas superficiales son la señal de entrada más común para los algoritmos de aprendizaje automático en aplicaciones de reconocimiento de gestos de la mano y estimación de la fuerza del dedo, sólo hay unos pocos sistemas disponibles comercialmente para la adquisición de EMG superficial. Este trabajo propone una matriz de electrodos superficiales seca, barata y fácil de fabricar. Este sistema utiliza múltiples sensores diferenciales activos integrados en una pequeña placa de circuito impreso de doble capa, cada uno de los cuales utiliza dos pequeñas áreas rectangulares de la capa inferior como capa conductora para la adquisición de la señal. Con una ganancia diferencial de 60dB entre 23 y 3000Hz y una relación de rechazo de modo común de -60dB a 60Hz. Se presentan los criterios de diseño y las simulaciones.

The flow redox that forms between the metallic transporters and their surroundings, gives rise to the oxidating process of the alloy of which they are done. The application of average mechanics and chemicals remove formed oxides, contributing to their rehabilitation. Of tried acids, the spirit of salt to 20%V, was the solution that fulfilled the specifications for the removal and cleaning (pickling) of a metallic structure. Then, the formation of oxidating centers was slowed down by means of the aspersion with aqueous solution of sodium nitrite to 20%V. Also, the drying to temperatures majors of 160ºC optimizes the passivation. The results obtained to different times show a mini formation of rust, the one that to industrial conditions is despicable.

Immunoprophylaxis for bovine babesiosis has two presentations of a live attenuated vaccine (fresh and deep-frozen). Despite being effective, their durability, as well as the conditions necessary for their transfer and handling, make them impractical. The incorporation of a third presentation, using dehydrated merozoites as immunogens, constitutes an innovative alternative, which combines practicality and stability over time. The objective of this work was to test dehydration processes and cryopreservative and rehydrating substances. For this, erythrocytes highly parasitized with Babesia bovis and B. bigemina were subjected to two dehydration techniques: lyophilization and spray drying. In turn, for the lyophilization process, several lyoprotectants were tested: Dimethylsulfoxide, Glycerol, Dextrose and Polyvinylpyrrolidone (PVP). The only one that achieved a properly dehydrated powder, c...
