Assessment of physicochemical characteristics and bioactive compounds of the essential oil of wild herbs aromatic from Andean region of South Perú.

Essential oils are a subject of study due to the heterogeneity of their components, which vary according to the genus and species of the plant material. The objective of this study was the physicochemical characterization and bioactive components of the essential oil (EO) extracted from wild punamuña (Satureja Boliviana) and runtuhuayra (Clinopodium Weberbaueri (Mansf.) Govaerts) herbs from high Andean areas of southern Peru.

Obtaining and Characterizing Andean Multi-Floral Propolis Nanoencapsulates in Polymeric Matrices.

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.

Microencapsulation of Erythrocytes Extracted from Blood in Matrices of Tara Gum and Native Potato Starch.

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%.

Modified Polymeric Biosorbents from for the Removal of Heavy Metals in Wastewater.

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 to remove metal cations in wastewater. Drying, grinding and sieving of the stems was carried out to obtain the biomass, retaining 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.
