Abstract
Total capsaicinoids is an important quality index of capsicums. It has been recommended that this index can be reliably estimated by a simple and rapid paper chromatographic method. Details of the method have been critically studied to establish the precision and reproducibility. Repeatability and reproducibility of the method were plus/minus3.12% and plus/minus6.63% (relative to mean), resp. In addition, the values by this method for samples of capsicums and their oleoresins, varying over a wide range of capsaicinoids content, were validated by a high correlation (r approx. = 1) to pungency values by the standardized threshold dilution method. In the light of the results presented, it is suggested that the total capsaicinoids be accepted as an index of pungency.
