Effect of processing and germination on the nutritional and bioactive properties of black amaranth ( Amaranthus hybridus ) cultivated over 2,700 m above sea level in Apurimac

Black amaranth (Amaranthus hybridus), an Andean pseudocereal, was evaluated to assess the effects of germination, roasting, and cooking on its nutritional profile, protein structure (SDS‒PAGE and FTIR), color, polyphenol content, antioxidant capacity (DPPH and ABTS), and flavonoi...

Quantifying the Photoelectrochemically Active Surface Area for Oxygen Evolution Metal Oxide Photoelectrocatalysts

Abstract Nanostructuring is established as a photoelectrode performance enhancing route for solar-driven catalytic processes. However, it is often unclear to what extent the increase in photoelectrode physical surface area directly results in a commensurate increase in photoelect...

Effect of planting density on the agronomic performance and forage potential of Vicia sativa L. in the high Andes of Peru

In the high Andean regions of Ancash, Peru, limited high-protein forage during dry seasons challenges livestock feeding. A locally adapted ecotype of common vetch ( Vicia sativa L.) grows spontaneously and shows resilience to harsh conditions. This study evaluates its agro-morpho...
