Abstract
In this study, risk estimation based on sampling and subsampling uncertainty was performed for pesticide
analysis in homogeneous spice products such as paprika. The results of the subsampling were also used to estimate
the minimum weight necessary in subsampling to minimize overall uncertainty. The results show that
subsampling has more uncertainty than sampling in the product due to high homogeneity in the manufacturer’s
batch. On the other hand, results using the Monte Carlo (MC) simulation on the size of the subsample indicate
that uncertainty is lower for weights between 20 and 30 g and increases for sample sizes of 100 g. A sample size
of 30 g was used for saffron, and the values simulated with the MC method were confirmed.
