In the camu camu (Myrciaria dubia) processing, the peels and seeds are the main residues with a high potential for use as they contain anthocyanins (peel) and phenolic compounds. The objective of this research was to take advantage of camu camu peels and seeds as ingredients for infusion filters, and to evaluate the effect of drying. First, the peels and seeds were dehydrated at three temperatures (50, 65 and 70°C) and characterized in total anthocyanins and total phenolic compounds. Then, they were sieved considering two size ranges: small (between 0.1 and 0.475 cm) and large (larger than 0.475 cm) to be evaluated sensorially by a trained panel as an infusion, using a hedonic scale of general acceptability of 10 cm. The results showed that the peels contain anthocyanins and a higher content of phenolic compounds. In the case of the sensory evaluation, the panel preferred the large-rang...

The objective of this work was to quantify either physical and chemical attributes of the whole along with grounded seeds from Castilla pumpkin (Cucurbita moschata Duchesne) and bitter pumpkin (Apodanthera undulata A. Grey). The parameters data for whole seeds of both pumpkin varieties were; physical dimensions, internal friction, external friction and particle size, while for their ground compound were; electric conductivity, soluble protein, total protein, carbohydrates, oil concentration and main minerals. Collected data is fundamental for generating technology for the productive processes and an aid for more efficient use of the entire organic mass, when new raw matter is obtained for separate processing areas, to diversify readily consumption produce and increasing productivity of agroindustrial mechanization. It was concluded that pumpkin crop raised all over this farming region of...

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 ...

Peasant agriculture and its agrobiodiversity systems are at a juncture in which two global processes impose significant challenges for their sustainability: climate change and the expansion of agricultural biotechnology supported by a regimen of intellectual property rights over plant genetic resources. In this article, I explore some potential risks these global processes impose on peasant agriculture, particularly on their seed systems. We analyze how, in response, peasant communities have increasingly mobilized around two converging political agendas, seed sovereignty and climate justice. In addition to the political achievements confronting some of the great biotechnology and corporate developments in the context of climate change, community peasant actions implemented to protect and defend their seeds directly contribute to reaffirming peasant seeds as part of peoples’ commons and...

In this research, an innovative mechanical- electronic device has been developed for the efficient purification of carrots seeds, a critical process in agricultural production due to its impact on the quality and yield of future crops. The device uses mechanical and electronic principles to effectively separate impurities and unwanted seeds from carrots. Through detection and classification technologies together with mechanical elements of transport and separation, the quality of the resulting seeds is sought to improve, ensuring their purity. This development represents a significant advance in the automation of agricultural production, enabling farmers to benefit from higher quality seeds and higher productivity. This project shows how the integration of mechanical and electronic technologies can address the challenges in food production. In addition, the carrot seed cleaning machine o...

The objective of the present study was to evaluate the extraction and microencapsulation of antioxidant compounds from Oenocarpus bataua Mart seed, commonly known as “ungurahui” or “patawa”. The extraction process was performed in an ultrasonic bath and the orthogonal composite central design of the response surface methodology (RSM) was used to determine the optimal extraction conditions, using two factors: ethanol concentration (48.44 to 91.56%) and extraction time (13.83 to 46.17 min). The optimal extraction conditions (48.44% ethanol and 13.83 min) allowed to obtain the extract (EUL) with the highest number of antioxidants (yield (YI): 24.64%, total phenolic content (TPC): 452.76 mg GAE/g EUL and DPPH: 74.26%). Microencapsulation of EUL with maltodextrin by spray drying produced microcapsules (EUM) of homogeneous size (5 µm), without cracks or fissures and that preserved its...

The fruit seeds, commonly regarded as waste after consuming the fresh pulp, emerge as a source of unconventional starch with innovative potential. This study focuses on highlighting the significance of these seeds by exploring chemical modification methods in this starch source that add value by transforming their properties. The review emphasizes the influence of key factors such as the type of chemical reagent, its concentration, reaction parameters (pH, temperature, time), and the botanical source of the seed on the degree of modification and the resulting morphological and functional properties of the starch. The importance of specific conditioning during the chemical modification process is underscored, as it significantly contributes to enhancing the properties of the modified starch derived from fruit seed. In this regard, new perspectives are opened to efficiently harness fruit s...

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....

Se Teniendo en cuenta que un producto, como la “quinua” es lo suficientemente nutritivo y digerible; es necesario que tenga un grado de hidrólisis que permita solubilizar la proteína, almidón, fibras, etc. cambiando sus propiedades organolépticas para hacerlo más aceptable y aprovechable. Por ello la investigación se orientó a determinar los parámetros cinéticos de pH, temperatura y concentración de sustrato que permitan el proceso de hidrólisis de harina de “quinua” en una proporción de 1 en 10 partes de agua, previamente gelatinizada, a la cual se le adicionó una suspensión de enzimas equivalente a 1,5g/1000 g (50% de alpha amilasa y 50 % de proteasa). Con lo cual se logro solubilizar las proteínas y reducir el almidón a azucares reductores, obteniéndose un producto liquido a una concentración promedio del 8,5 %, que fue posteriormente concentrado a 45 % de s...
