Currently, the food industry prioritizes the safety and quality of products, facing the challenge of maintaining sensory and nutritional integrity. To address this challenge, emerging non-thermal technologies are being explored that offer significant advantages in improving food quality over conventional technologies. This review aims to provide a comprehensive understanding of how these innovative technologies can transform the traditional food processing landscape as we know it. Non-thermal technologies have the potential to reduce energy consumption for food production, processing and packaging, compared to conventional thermal treatments. Furthermore, these technologies are particularly suitable for efficiently preserving bioactive compounds present in foods. This review describes the fundamental principles, applications, advantages and limitations of emerging technologies in food pr...

Accurate determination of plant water status is mandatory to optimize irrigation scheduling and thus maximize yield. Infrared thermography (IRT) can be used as a proxy for detecting stomatal closure as a measure of plant water stress. In this study, an open-source software (Thermal Image Processor (TIPCIP)) that includes image processing techniques such as thermal-visible image segmentation and morphological operations was developed to estimate the crop water stress index (CWSI) in potato crops. Results were compared to the CWSI derived from thermocouples where a high correlation was found ( = 0.84). To evaluate the effectiveness of the software, two experiments were implemented. TIPCIP-based canopy temperature was used to estimate CWSI throughout the growing season, in a humid environment. Two treatments with different irrigation timings were established based on CWSI thresholds: 0.4 (T...

In this paper, the technical, financial and legal feasibility of employing solar cogeneration for the food industry sector in Peru will be demonstrated. In consequence, we will quantify the electric and thermal energy obtained from a conventional Rankine cycle, with the particularity that the water used to condense the steam that exits the turbine will be employed for the required processes in the industrial plants, because of the high temperature obtained from the heat exchange with the steam. In addition, we will detail the processes in which the obtained energy will be employed, the quantity of devices to be used in this system, as well as the required specifications and the thermodynamic parameters, for a proper operation of the cogeneration system. Moreover, we will prove the legal feasibility of choosing a solar cogeneration system in the Peruvian legal system, and, in ...

Evaluate the effect of gaseous ozone on physicochemical characteristics, molds and yeasts count and overall appearance of granada. Wonderful variety fruits of granada was collected in a glass chamber where the gas is injected using ozone generator equipment with flow of 500 mg / h and a digital meter for measuring the ozone concentration. A central composite design rotable (CCDR) was used to analyze the effect of the concentration of ozone gas and storage time (p < 0.05) on weight loss, firmness, shell color, soluble solids, mold and yeasts count, total anthocyanins content and overall appearance. It was determined that the concentration of ozone gas had significant effect on the responses studied variables. The quadratic model provided the best fit of data. It was established that the concentration of ozone between 40 - 50 ppm, it allows for the lowest weight loss, low count of molds...

In this work we study the effects on the porosity and microhardness properties when using different ZrO2 + 8% Y2O3 diameters powders (less than 40 μm, between 40 to 60 μm and greater than 80 μm) to deposit in the upper layer of a TBC system (thermal barrier coating) of double layer formed by NiCrCoAlY and ZrO2 + 8% Y2O3 using the plasma spray process, in order to find the suitable powder and feasible to use as top layer. To this end, instruments such as TESCAN Vega SB scanning electron microscope with INCA Energy dispersive microanalyzer were used, with which it was possible to detect the porosity in different areas of evaluation of the upper layer and the Vickers durometer to measure the microhardness. Verifying that with particle diameters smaller than 40 μm, the aforementioned properties are adequate for the conformation of the ZrO2 + 8% Y2O3 top layer.

The process of hydrolysis was carried out on a suspension of quinoa flour in water in a proportion of 1 in10 parts of water, previously gelatinized, to which was added an equivalent suspension of enzymes of 1,5 g/1000 g (50% of alpha amylase and 50% protease). With that, proteins were solubilized and starch was reduced to reducing su- gars, obtaining a liquid product at an average concentration of 8,5% that was later con- centrated to 45% of total solids. The hydrolysis process allows, on the basis of 1 kg of quinoa flour, toobtain80 to 85% of hydrolyzed material from20 to 15% of cellulosic residue, proteins and carbohydrates, non-digestible by the enzymes. The experiences that were carried out brought as results the following optimum values of kinetic parameters: Concentration of substrate: 10,0 %; Temperature: 60 ºC; pH: 5,0 and enzyme con- cent...

La situación problemática de la presente investigación se centra en la deficiencia del cálculo de los tres elementos del costo: Materia prima, mano de obra y costos indirectos de fabricación. Puesto que en la actualidad la empresa cuenta con un sistema de costeo tradicional, el mismo que no permite identificar adecuadamente los costos incurridos en cada proceso productivo y por ende los cálculos de los costos obtenidos por cada departamento no determinan fehacientemente el precio unitario del producto. El presente estudio tiene como objetivo general elaborar una estructura de costeo por procesos en la producción de cereales en hojuelas y su efecto en la rentabilidad de la empresa Productos La Selecta S.R.L Tarapoto, año 2015, para tal fin, se utilizó una metodología de tipo cuantitativa, la cual estuvo dirigida a valorar monetariamente e interpretar los procesos de costos; por ...

Chronic wounds are a serious health problem because they do not follow a normal healing process and take a long time to heal. Monitoring the evolution of the wound is vital to evaluate the current treatment and determine the need for a different approach. Traditionally, this assessment is based on manual measurements and visual observation, which can be subjective and non-quantitative, leading to uncertainty in patient follow-up. This thesis proposes to leverage color and thermal imaging from cameras embedded in a smartphone to provide a non-invasive tool for wound assessment. Standard and affordable devices enables its applicability and scalability in clinical settings. We propose a methodology to create realistic and accurate 3D thermal models from a set of images captured with affordable and handheld devices. This approach was automated and evaluated in clinical settings on a total of...

Climate change significantly impacts the lifestyle of people living in high Andean areas. For children, heat, combined with other environmental factors like humidity, leads to exhaustion — something experienced daily. Prolonged exposure to heat can cause side effects such as anxiety, and depression, and contribute to mass migrations and regional conflicts, affecting local communities. Given these concerns, this research focuses on the thermal comfort of all types of buildings, whether residential or public. It proposes the importance of controlling internal temperatures, much like green walls or building placement systems that allow air to flow freely, creating cool chambers with stable temperatures for a greater sense of comfort. To achieve this, a system of modular architectural membranes was designed and prototyped. These membranes are tailored to the specific needs of the geographi...
