A model based on clusters of similar color and NIR to estimate oil content of single olives
Fredes, Claudio ; Valero, Constantino; Diezma, Belén; Mora, Marco ; Naranjo-Torres, José; Wilson, Manuel; Delgadillo, Gabriel (2021)Lipid extraction using the traditional, destructive Soxhlet method is not able to measure oil content (OC) on a single olive. As the color and near infrared spectrum are key parameters to build an oil estimation model (EM), ...
