The variability effect of kinetic data was investigated by simulating orange juice pectinmethylesterase (PME) inactivation with combined processes of high hydrostatic pressure-temperature (100-500 MPa; 20-40°C), applying the Monte Carlo method. Parameters from an Eyring-Arrheniius model that predicts the kinetic inactivation constant (k) as a function of both pressure and temperature...
The essential oil from two Lantana species (Lantana lucida Schauer and Lantana salzmannii Schauer) were evaluated for their chemical composition by GC-MS. Results showed 17 predominant compounds for L. lucida, among which β-caryophyllene (19.0%) and α- caryophyllene (or humuleno, 33.0%) were the major components. L. salzmannii showed the presence of...
The research was conducted in the Fundo Almendra, property of the National University of the Peruvian Amazon (UNAP). The objective was to analyze the gross forest loss in the period 2001-2021 in Fundo Almendra, the relationship between forest loss and local surface temperature, and the role of local communities’ demographics...
