Abstract

Optical properties could be used for different purposes. Jongguk Lim et al developed a method for predict the amount of capsaicin in red-pepper powder using Visible and near infrared spectroscopy, based optical properties of capsaicnoids [1]. Also González-Zamora Alberto et al propose a spectrometric method for quantify capsaicnoids in chiltepin hot pepper [2]. All this techniques are based in the knowledge of optical properties of this substances. The main objective is establish a theoretical model that relate diffuse reflectance signals with the capsaicin at different concentrations. In this research is proposed a simple method for recover optical properties. Based on re-mission function from Kubelka-Munk theory an experiment was performed, for establish a relation between concentrations of an oleoresin with capsaicin and diffuse reflectance signals [3]. The results of this experiment show that reflectance from the mentioned theory, the fit analisys has a goodness approximation.
