There is a growing concern in environmental pollution levels of the neighboring ecosystems fruit processing plant by the discharge of untreated industrial effl uents and proper control of the authorities, because many of them have not considered the management their effl uents into the design of the plant. The objective of this research is to characterize and manage the processing effl uent. We conclude that the processing effl uents have a high potential for contamination by the abundant organic load and that have achieved the primary treatment of this potential reduction to acceptable limits by Peruvian law (98.1% turbidity removal and reduction of BOD Oxygen 96.58%), allowing the reduction of water consumption, release of hardship and its incorporation as a business friendly environment for approval of environmental authorities and the community as a whole.

La degradación de los bosques tropicales afecta el sustento de las comunidades reduciendo la disponibilidad de recursos. Sin embargo, los factores causantes de degradación y el impacto que ésta ejerce sobre las comunidades permanecen poco entendidos. En la Amazonía Peruana, los frutos de la palmera Mauritia flexuosa son un importante recurso, no obstante, el aprovechamiento se realiza típicamente talando las palmeras en fructificación. M. flexuosa presenta individuos masculinos y femeninos, y la proporción de palmeras femeninas (PPF) en el bosque fue usado como indicador del nivel de degradación. Data colectada en 70 sitios, seis cuencas hidrográficas y 27 comunidades, mostró que la PPF varió ampliamente (0.03-0.52). El tiempo de viaje desde la comunidad hasta el principal mercado regional (r2=0.19, p <0.001) y la técnica de cosecha (r2=0.17, p <0.001) están más relacionada...

Given the importance of the Chilean dried-fruit market and the characteristics of the industrial process of dehydration, it becomes imperative for companies to measure the efficiency of their production processes in order to identify critical areas and take the necessary actions to improve them. Hence, the present work performs an efficiency analysis for the production of dried apples in a plant of the Maule region, Chile. The methodology used is Data Envelopment Analysis, considering both discretionary and non-discretionary variables. The results indicate that the application of the model without non-discretionary variables shows higher efficiency indices than the model with non-discretionary variables. Additionally, the efficiency analysis results, segregated by variety, origin, and fruit type, indicate that the selection of these segregations could be used to increase the production o...

The promotion of organic and ecological production seeks the sustainable and competitive growth of organic crops in countries like Peru. In this context, agro-exportation is characterized by-products such as fruit and vegetables where they need to comply with organic certification regulations to enter products into countries like the US, where it is necessary to certify that weed control is carried out using biodegradable materials, flames, heat, media electric or manual weeding, this being a problem for some productive organizations. The problem is related to the need to differentiate between the crop and the weed as described above, by having image recognition technology tools with Deep Learning. Therefore, the objective of this article is to demonstrate how an artificial intelligence model based on computer vision can contribute to the identification of weeds in basil plots. An iterat...

Camu camu is a typical Amazon native fruit shrub that possesses a diploid genome, moderate genetic diversity, and population structure. The fruits accumulate several essential nutrients and synthesize L-ascorbic acid (vitamin C) in great quantities and an array of diverse secondary metabolites with corroborated in vitro and in vivo health-promoting activities. These beneficial effects include antioxidative and antiinflammatory activities, antiobesity, hypolipidemic, antihypertensive and antidiabetic effects, DNA damage and cancer protection effects, and other bioactivities. Many health-promoting phytochemicals are biosynthesized in several metabolic pathways of camu camu. Their reconstruction from the fruit transcriptome database was accomplished by our research group. These include basic metabolic pathways such as glycolysis and pentose phosphate pathway, vitamin C biosynthesis pathways...

Fruit processing generates large amounts of by-products (BPs) that play a key role in the economic, social and environmental crisis. Although these residues are not usually used, they have better nutritional and bioactive value than the edible part. Considering that the circular economy is a sustainable approach to promote a zero waste processing system, the objective of this study was to use bibliometric analysis and data mining to provide a body of knowledge on trends in the field of research on fruit BPs under circular economy strategies. The publication of the SDGs has stimulated the adoption of circular economy strategies to use fruit BPs, which was reflected in the growth of scientific production since 2015. Although it is suggested that the field of study is at an exponential stage, development is limited by the lack of regulatory instruments to regulate the use of fruit BPs. The ...

Sweetener type can influence sensory properties and consumer’s acceptance and preference for low-calorie products. An ideal sweetener does not exist, and each sweetener must be used in situations to which it is best suited. Aspartame and sucralose can be good substitutes for sucrose in passion fruit juice. Despite the interest in artificial sweeteners, little is known about how artificial sweeteners are processed in the human brain. Here, we applied the convolutional neural network (CNN) to evaluate brain signals of 11 healthy subjects when they tasted passion fruit juice equivalently sweetened with sucrose (9.4 g/100 g), sucralose (0.01593 g/100 g), or aspartame (0.05477 g/100 g). Electroencephalograms were recorded for two sites in the gustatory cortex (i.e., C3 and C4). Data with artifacts were disregarded, and the artifact-free data were used to feed a Deep Neural Network with tree...
