A fast and non-destructive method is reported to nitrogen, phosphorus potassium quantification in sorghum, oat, maize residues. The reflectance spectra of 261 litter plant samples using near-infrared spectroscopy were obtained with integrating sphere sampling rotator. Second derivative Partial Least Squares used develop calibration validation models. cross-validation (leave-one-out) technique was evaluate the performance models, based on analytical parameters, root-mean-square error...
Abstract The chemical composition of propolis is complex and varies according to location, seasonality, vegetation where the hives are located. Raw macerated produced in different regions Brazil were assessed iPLS models from FTNIR combined multivariate calibration determine total phenolic content (TPC). spectra raw obtained analyzing samples directly, without treatment or processing, while was submitted milling process using liquid nitrogen. Concerning results, TPC ranged 3.61 90.4 mg GAE g...
Las bayas Physalis, de la familia Solanaceae, han alcanzado una gran aceptación en todo el mundo debido al sabor fruta y su posible uso medicinal. Este estudio tuvo como objetivo evaluar actividad antioxidante, las concentraciones vitamina C, compuestos fenólicos azúcares frutas dos especies Physalis (Physalis pubescens L. peruviana L.), así sus variaciones durante almacenamiento temperaturas diferentes. El fue plantado oeste Santa Catarina. Los frutos se cosecharon cuando cápsulas eran...
