Description
Label a food-composition component's supplied missingness or trace state.
Dietary arithmetic depends on as-purchased versus edible mass, per-serving versus per-100-gram bases, measured versus trace states and recall periods. A recorded allergen list is not a verified allergen-free declaration. Portion counts, label intervals and mass differences use supplied assumptions rather than establishing actual intake or nutritional suitability.
Label a food-composition component's supplied missingness or trace state.
When to use this tool
Use Food Composition Missing Vs Trace Token when you already have componentId, status and need to label a food-composition component's supplied missingness or trace state.
How to use the tool and how it works
- Enter componentId, status. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require componentId nonempty and status measured/trace/missing/not-applicable; append the status.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| componentId | Component Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| status | Preserves measured/trace/missing/not-applicable categories without a numeric imputation. | Required. Text; one of "measured", "trace", "missing", "not-applicable"; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Label | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"componentId": "C17",
"status": "trace"
},
"output": {
"label": "C17 [trace]"
}
}Limitations and assumptions
- No numeric amount is returned or imputed. Trace and missing are not treated as measured zero, and no nutritional conclusion is made.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Check original food labels, composition sources, ingredient/allergen information and dietary records before combining amounts. Use a complete appropriately interpreted dietary assessment when requirements or suitable intake matter; local scaling and source labels do not make those judgments.
