Abstract

The quality degradation of chilli during comminution was investigated through modelling. Two different comminution methods were studied, namely grinding and high‐speed cutting. The colour of the chilli powders, the concentration of two major capsaicinoid compounds, and moisture loss in the powders were taken as the quality indicators. The kinetics of quality degradation was modelled. It was found that although the quality indicators of chilli powder produced by grinding were generally inferior to those by high‐speed cutting, the rate of quality degradation by the former was much lower than that by the later. The mechanism behind this finding is also discussed in this paper.

People experience physiological changes with age which may lead to changes in sensitivity to many kinds of exposure. In situations of prolonged, low level exposure, differences in the effects of exposures received at different ages may be diffΔ±cult to evaluate, since study members receive low level
