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.

Effect of the Application of a Coating Native Potato Starch/Nopal Mucilage/Pectin on Physicochemical and Physiological Properties during Storage of Fuerte and Hass Avocado ().

The avocado fruit is an agro-industrial product with high export demand in Peru due to its sensory and nutritional qualities, which can be affected during storage. The study aimed to evaluate the effect of the application of a coating formulated with potato starch (Solanum tuberosum ssp andigena), nopal mucilage (Opuntia ficus indica), and pectin on the physicochemical and physiological properties during the storage of Fuerte and Hass avocados. Samples were taken in their harvest state from the plantation in “Occobamba”, which is cultivated by the Avocado Producers Association in Chincheros, Apurímac, Peru.

Formulation of Novel Composite (Activated Nanoclay/Hydrocolloid of ) and Its Application in the Removal of Heavy Metals from Wastewater.

The removal of heavy metals from wastewater is an environmental challenge which demands the use of environmentally friendly materials that promote a circular economy. This study aimed to apply a novel composite of an activated nanoclay/hydrocolloid in the removal of heavy metals from wastewater. A composite blended under pressure was prepared with spray-dried hydrocolloid derived from Nostoc sphaericum algae and activated nanoclay in an acid medium and 1M NaCl.
