Multivitamin Premix
Multivitamin Premix Quality Checker — Multivitamin Premix (Vitamin and Mineral Complex)
ℹ️ The utility checks content of 10 vitamins, 5 minerals, general parameters (loss on drying, heavy metals, microbiology, uniformity).
ℹ️ Does not use machine learning — rule-based logic only.
⚠️ Critical for dietary supplements, vitamin complexes, parenteral nutrition, infant nutrition.

— WHY IS THIS NEEDED?
Multivitamin premixes are complex mixtures of vitamins and minerals used in:
• Dietary supplements and vitamin complexes for deficiency prevention
• Parenteral nutrition (TPN) for patients with malabsorption
• Infant nutrition and medical foods
• Pharmaceutical products (multivitamin tablets)
• Animal feed additives
Critical parameters:
• Each component content: 90.0–110.0% of declared (dose assurance)
• Loss on drying ≤5.0% (mixture stability)
• Heavy metals ≤20 ppm (safety)
• Microbiology: TAMC ≤1000 CFU/g, TYMC ≤100 CFU/g (purity)
• Mixture uniformity (RSD ≤5.0%) — critical for accurate dosing in tablets
• pH 5.0–7.0 (component stability)
• Clarity ≤5 NTU, color ≤50 APHA (for liquid forms)
⚠️ Special attention: component interactions (e.g., vitamin C and iron), light- and heat-sensitivity (vitamins A, D, B12), need for separation in granules for stability.
Specification compliance is mandatory for registration and release.

|---|---|---|
| TC-001 | Valid CSV with expected header and sample row | All rows are processed; output contains PASS/WARNING/FAIL and parameter-level detail. |
| TC-002 | A mandatory input.csv column is missing | Import is rejected or the row receives FAIL with schema reference. |
| TC-003 | A numeric field contains text or a blank value | Type conversion error is recorded; the result is not hidden as PASS. |
| TC-004 | A parameter is outside specification or critical limit | Critical parameters produce FAIL; non-critical deviations produce WARNING according to the rule. |
| TC-005 | Positive pathogen/microbiological flag or microbiological limit excursion | Critical FAIL is produced with the offending parameter. |
| TC-007 | Residual solvent above applicable limit | FAIL is produced with solvent name and measured value. |
10. QA/QC, CSV and change control
- Before production use, the client records executable version, checksum, specification/monograph version, test CSV, expected JSON and IQ/OQ results.
- Column names must not be changed without updating the validator and test scenarios.
- The source CSV, output.json and utility version should be stored together as an evidence package.
- Any change in control rules must go through change control and repeated OQ scenario verification.
