Voltammetric Determination of Chili Peppers Pungency using Phospholipid Modified Glassy Carbon Electrode\n
Skopalová, J. ; Rajcová, A. ; Vokounová, D. ; Navrátil, Tomáš
The aim of this study was to develop a simple method for evaluation of the pungency in chili peppers with a glassy carbon electrode modified using phospholipid membrane prepared from asolectin. For these purposes cyclic voltammetry (CV) and differential pulse voltammetry (DPV) have been used. A few different methods have been tested: direct method, transfer method on unmodified and modified electrode, using standard addition method as well as calibration curve method. A statistically significant correlations with the results of the reference HPLC method have been found in case of voltammetric methods, especially in DPV with asolectin modified electrode.
