In this study, the stability of the sensory quality and viable mesophilic aerobic (AMV) counts of llama ground meat with the addition of sanky (Corryocactus brevistylus subsp. puquiensis (Rauh & Backeberg) Ostolaza) peel ultrasound-assisted extract (CES) was evaluated during storage at 5°C , the added extract volume was calculated to obtain a concentration of 60 mg PT / kg of llama ground meat. The instrumental parameters of color (L*, a*, b*), pH, AMV and sensory properties were determined during nine days. The samples without extract (CO) presented higher values​​ of a* (redness) than the CES samples; however, the L* (luminosity) and b* (yellowness) values ​​did not show significant differences for the CES treatment during storage. The color difference (ΔE0-9) during storage was greater for the CO treatment, indicating significant changes in color and odor that were perce...

The aim of this study was to perform a descriptive analysis to evaluate the sensory properties and color parameters in the llama burger with sanky peel powder. Sensorial characterization was performed using the static sensory analysis technique, quantitative descriptive analysis (QDA), which provides information on the intensities of the sensory properties at a specific point in time. The antioxidant capacity of the sanky peel was quantified (77,50 ± 0,98 µmol trolox equivalents/g dry weight), a panel of sensorial judges was trained, flavor, aroma, texture and appearance were evaluated, furthermore color, pH and microbiological parameters were evaluated. QDA revealed that the sanky peel powder in the llama burger improved the scores of the sensory properties: salty taste, sour taste, oregano flavor, firm appearance and general acceptability, however no significant difference among sens...

There are several investigations on the use of food waste to remove contaminants by adsorption. However, a simple route, without chemical activation reagents, is needed for the development of adsorbents. The aim of this study was to develop an adsorbent from plantain peel, using a simple procedure, and to evaluate its capacity to remove phosphate from aqueous solutions at phosphate concentrations similar to those of water sources at risk of eutrophication (0.30 mg/L). The simple pyrolysis method was used in an electric muffle, without chemical activation, using plantain peel as precursor. The variables evaluated were pyrolysis temperature and solution pH. The specific surface area BET, zero loading point of the developed treatments, was determined. Phosphate adsorption was studied in a batch experiment in the presence of calcium ions in solution. Phosphate adsorption was favorable at all...

Las infusiones son bebidas elaboradas a base de hierbas y otros materiales vegetales, consideradas saludables por la presencia de compuestos bioactivos. El objetivo del presente estudio fue evaluar la actividad antioxidante, compuestos fenólicos y evaluación sensorial de formulaciones para infusión a base de cáscara de sanky y canela. Los tratamientos estudiados incluyeron 100% de cáscara de sanky (INF100), 70% de cáscara de sanky +30% de canela (INF70) y 50% de cáscara de sanky +50% de canela (INF50). El contenido fenólico y la actividad antioxidante variaron significativamente (p < 0,05). El contenido de fenolestotales fue 1040; 3616 y 5353 μg GAE g-1 para los tratamientos INF100, INF70 y INF50 respectivamente. La actividad de barrido del DPPH fue 1116,67; 1647,33 y 2017,00 μg de TEAC g-1 y la actividad de barrido ABTS fue 2090; 8920 y 13425μg de TEAC g-1 para los tratami...

La bebida fue elaborada en base a pulpa de piña (Ananas comosus) y quinua (Chenopodium quinoa Willd), en proporción 7:1 (p:p), procesada mediante tres tratamientos térmicos diferentes TP01, TP02 y TP03 (85 ºC x 26 minutos, 90 ºC x 7 minutos y 95 ºC x 2 minutos). Las características físico-químicas evaluadas fueron: pH, grados Brix y viscosidad. Los atributos sensoriales de consistencia y sabor (global) fueron evaluados con un panel conformado por 15 jueces entrenados. Los resultados presentaron diferencias estadísticamente significativas entre los tratamientos en cuanto a la viscosidad y consistencia; en la evaluación de sabor como atributo sensorial global no se reportaron diferencias e...

El objetivo del artículo es realizar una valoración crítica del comportamiento ecológico del ciudadano latinoamericano a partir de la influencia de las corrientes filosóficas del pensamiento ambiental en la región, para ello, se usó como metodología el análisis hermenéutico de obras de grandes pensadores de la región, como Boff (1997, 2012, 2015), Maya (2003, 2008), Rozzi (2001, 2007, 2012), Leff (2010, 2011, 2020), entre otros. Se pudo determinar que la conducta ecológica ciudadana ha estado regida por las directrices del sistema político imperante, basado en el principio único de explotación de recursos naturales para obtener beneficios económicos, dejando de un lado el pensamiento ecocéntrico, se espera, que el reciente acuerdo de Escazú y la influencia ejercida de pensadores ecológicos modele el comportamiento social, partiendo de la democratización de la informac...

The ultrasound-assisted extraction allows to recover bioactive substances in the agroindustrial waste, besides, is a fast, clean and friendly with the environment technique. The extraction of total phenolic components by ultrasound was carried out on the peel of the fruit of the sanky (Corryocactus brevistylus). This plant is a cactus that grows in the Andes of Peru and its fruit is used by the communities. The sanky peel reported: humidity 10,74 %; protein 9,19 %; ashes 14,75 %; 2,68 % fat; fiber 16,39 % and nitrogen-free extract 46,25 %. The sanky seeds reported 207,81 ppm of calcium, 39,36 ppm of iron and 9,4 ppm of zinc. For the extraction, three factors and each one in three levels were evaluated: solvent concentration (40 %, 50 % and 60 %), time (20, 30 and 40 minutes) and temperature (25, 35 and 45 °C). The design of Box Behnken was used, reporting 15 experimental trials. The tot...

There are many native fruits in Peru containing essential nutrients for health and that have not been fully studied. The objective of this research was to determine the physicochemical, nutritional and morphological characteristics of five varieties of native fruits from the central Andean region and the northern Peruvian jungle: goldenberry (Physalis peruviana), sanky (Corryocactus brevistylus), cocona (Solanum sessiliflorum), yellow pitahaya (Selenicereus megalanthus) and camu camu (Myrciaria dubia). The fruits were washed, peeled, pulped, fleshed, and lyophilized, to determine, using standardized analytical methods, the nutrient content, such as vitamin C, fiber, soluble solids. The goldenberry, sanky and camu camu fruits presented the highest vitamin C content (43.0, 57.1 and 2,780 mg per 100g of fresh weight, respectively), while cocona and pitahaya had 4.54 and 8.0 mg per 100g of f...
