La contaminación de cuerpos hídricos con metales pesados como el plomo (Pb) y el arsénico (As) representa un grave riesgo para la salud pública y el medio ambiente, haciendo crucial el desarrollo de métodos efectivos de remoción. Este estudio evaluó la biosorción de Pb y As utilizando biomasa vegetal inerte de tallos de puka kora (Rumex acetosella), recolectada en el distrito de San Jerónimo, Andahuaylas, Perú. La biomasa fue activada mediante tratamientos de hidrolisis ácida (T2), alcalina (T3) y una combinación ácida-básica (T4) para ser utilizada en ensayos en batch. Se realizaron pruebas preliminares para determinar la capacidad de remoción de Pb y As en soluciones de 10 ppm a pH 5, utilizando 0.2 g de biosorbente en 800 ml de solución. Los metales en solución se analizaron mediante espectrofotometría de emisión óptica por plasma acoplado inductivamente, y se util...

La papa es un alimento básico y es fuente de compuestos con actividad antioxidante, estas sustancias en pequeñas concentraciones son capaces de reaccionar con las Especies Reactivos de Oxigeno (ERO), implicadas en numerosos acontecimientos relacionados con enfermedades cardiovasculares y el envejecimiento, para proteger el sustrato y combatir el daño celular. Los clones de papa nativa fueron producto del trabajo de varios años dentro de la empresa SEMPAL y se encuentran a nivel de cuarta y quinta generación, lo que originó que los valores de los compuestos bioactivos se concentren, llegando a obtener valores muy altos. En el trabajo de investigación se estudiaron a cinco clones de papa nativa (Solanum tuberosum), con el fin de determinar la capacidad antioxidante y los compuestos bioactivos: fenoles y antocianinas totales. La capacidad antioxidante fue determinada a través de la ...

The province of Andahuaylas is located in the region of Apurimac, a Peruvian city located in the Andes. Andahuaylas has three important districts: San Jerónimo, Andahuaylas and Talavera. These areas are highly populated, and their buildings are close to the Chumbao River. This research aimed to determine the influence of anthropogenic activities on the concentration of pesticides, physicochemical and microbiological characteristics in the Chumbao River. Five agricultural activities, 19 organochlorine pesticides, and 25 organophosphorus pesticides were studied. Eighteen physicochemical properties and two microbiological properties were also studied at seven sampling points along the Chumbao River during the rainy and dry seasons. Several veterinary and agricultural products were identified in the agricultural activities studied. However, no significant concentration values of organochlor...

The contamination of water resources by effluents from various industries often contains heavy metals, which cause irreversible damage to the environment and health. The objective was to evaluate different biosorbents from the weed Rumex acetosella to remove metal cations in wastewater. Drying, grinding and sieving of the stems was carried out to obtain the biomass, re taining the fractions of 250 to 500 µm and 500 to 750 µm, which served to obtain the biosorbents in natura (unmodified), acidic, alkaline, and mixed. Proximal analysis, PZC, TOC, removal capacity, influence of pH, functional groups, thermal analysis, structural characteristics, adsorption iso therms, and kinetic study were evaluated. The 250 µm mixed treatment was the one that presented the highest removal percentages, mainly due to the OH, NH, -C-H, COOH, and C-O functional groups achieving the removal of up to 96.14% ...

Propolis is a substance with significant anti-inflammatory, anticancer, and antiviral activity, which could be used more efficiently at the nano level as an additive in the food industry. The aim was to obtain and characterize nanoencapsulated multi-floral propolis from the agro-ecological region of Apurimac, Peru. For nanoencapsulation, 5% ethanolic extracts propolis with 0.3% gum arabic and 30% maltodextrin were prepared. Then, the mixtures were dried by nano spraying at 120 ◦C using the smallest nebulizer. The flavonoid content was between 1.81 and 6.66 mg quercetin/g, the phenolic compounds were between 1.76 and 6.13 mg GAE/g, and a high antioxidant capacity was observed. The results of moisture, water activity, bulk density, color, hygroscopicity, solubility, yield, and encapsulation efficiency were typical of the nano spray drying process. The total organic carbon content was aro...

Ferropenic anemy is the leading iron deficiency disease in the world. The aim was to encapsulate erythrocytes extracted from the blood of Cavia porcellus, in matrices of tara gum and native potato starch. For microencapsulation, solutions were prepared with 20% erythrocytes; and encapsulants at 5, 10, and 20%. The mixtures were spray-dried at 120 and 140 ◦C. The iron content in the erythrocytes was 3.30 mg/g and between 2.32 and 2.05 mg/g for the encapsulates (p < 0.05). The yield of the treatments varied between 47.84 and 58.73%. The moisture, water activity, and bulk density were influenced by the temperature and proportion of encapsulants. The total organic carbon in the atomized samples was around 14%. The particles had diverse reddish tonalities, which were heterogeneous in their form and size; openings on their surface were also observed by SEM. The particle size was at the nanom...

The cellulose from agroindustrial waste can be treated and converted into nanocrystals or nanofibers. It could be used to produce biodegradable and edible films, contributing to the circular economy and being environmentally friendly. This research aimed to develop an edible film elaborated with activated cellulose nanocrystals, native potato starch, and glycerin. The ac tivated cellulose nanocrystals were obtained by basic/acid digestion and esterification with citric acid from corn husks. The starch was extracted from the native potato cultivated at 3500 m of alti tude. Four film formulations were elaborated with potato starch (2.6 to 4.4%), cellulose nanocrystals (0.0 to 0.12%), and glycerin (3.0 to 4.2%), by thermoforming at 60 ◦C. It was observed that the cellulose nanocrystals reported an average size of 676.0 nm. The films mainly present hydroxyl, carbonyl, and carboxyl groups t...
