Food conversion settings¶

Calculation settings¶

Table 107 Calculation settings for module Food conversions.¶
Name	Description
Include foods with only non-detect measurements	Specifies whether foods with only non-detect measurements are part of the exposure assessment (default yes).
Include substances with only non-detect measurements	Specifies whether substances with only non-detect measurements are part of the exposure assessment (default yes).
Include substances without measurements	Specifies whether substances without any measurements should be included.
Step 2: allow conversion using processing info	Try to find the code in the processing table (step 2a). Processing link wildcard match: try to find a wildcard match in the processing table (step 2b) e.g. code FP026 matches FP* in column FoodProcessed where ‘*’ is used as a wildcard match for ‘026’. Try to find the code in the FoodTranslation table (step 3a) to account for weight reduction/increase. If unchecked, processing table is ignored, default is ‘Use processing info’. If successful, restart at step 1.
Step 3a: allow conversion using food translations	Step 3a: Try to find food translations for the current food (i.e., the ingredients of a composite food). This may result in one or more food codes for ingredients, and the iterative algorithm will proceed with each of the ingredient food codes in turn.
Step 3b: allow conversion using TDS food sample compositions	Step 3b: Try to find the code in the TDS food sample compositions table (idFood), a default translation proportion of 100% is assumed. The iterative algorithm will proceed with a TDS food (column idTDSFood) sample.
Step 3c: allow conversion using food extrapolations	Try to find read accross codes. If unchecked, read across table is ignored, default is ‘Use read across info’. E.g. for pineapple no measurements are found but by specifying that pineapple is converted to FruitMix (with a default proportion of 100%), the TDS sample concentration value of FruitMix will be used for pineapple (as-eaten or as ingredient). If successful, restart at step 1.
Step 4: allow conversion using market shares	Try to find subtype codes, e.g. ‘xxx$*’ in the market shares table.
Allow marketshares not summing to 100%	Specify whether to rescale market share percentages that do not sum to 100%. If true, then foods with marketshares not summing to 100% are allowed. If not, then these foods are ignored in the analysis.
Step 5: allow conversion to supertypes	Try to find supertypes, e.g. ‘xxx$yyy’ is converted to ‘xxx’ (optional, check box if you want to use this). If checked, allows for linkage of consumed foods coded at a lower hierarchical level to foods with measured concentrations at a higher hierarchical level e.g. consumed is Apple (code PF$Apple) –> measured is Pome Fruit (code PF). Note: food codes are split on ‘$’. Measurements of substances on food are available at a less detailed food coding level than consumption data. MCRA allows to use the concentration data of a supertype for all underlying food codes. If successful, restart at step 1.
Step 6: allow conversion using default processing factors	Remove processing part. If unchecked, no default processing factors are assumed, default is ‘Use default processing factors’. If successful, restart at step 1.
Include foods without occurence data but with specified maximum residue limits	Include foods without concentration data but for which for which concentration limits such as MRLs are defined (default: no).
