Qualitative evaluation of the influence of uncertainties on the dietary exposure estimate
| Sources of uncertainties | Direction of impact |
|---|---|
| Model input data | |
| Consumption data: different methodologies/representativeness/underreporting/misreporting/no portion size standard | +/− |
| Use of data from food consumption surveys of a few days to estimate long‐term (chronic) exposure for high percentiles (95th percentile) | + |
| Possible national differences in categorisation and classification of food | +/− |
| Model assumptions and factors | |
| Exposure to food enzyme–TOS was always calculated based on the recommended maximum use level | + |
| Selection of broad FoodEx categories for the exposure assessment | + |
| Use of recipe fractions to disaggregate FoodEx categories | +/− |
| Use of technical factors in the exposure model | +/− |
|
Exclusion of other processes from the exposure assessment – Production of plant extract as flavouring preparations – Coffee demucilation | − |
+: uncertainty with potential to cause overestimation of exposure.
–: uncertainty with potential to cause underestimation of exposure.
