OIT-002 / 2.1
Allergen identity and protein basis
Distinct food-allergen raw materials in separate dossiers: pistachio, peanut, cashew and, where a specific project is approved, milk/egg proteins.
Procedure
- Qualify the specific source and material: species, nut fraction, processing, milling, defatting and additives. A trade name does not establish equivalence.
- Record lot, dates, conditions and possible other allergens. A roasting or supplier change is a critical change.
- Define with the analytical partner what the test measures: total protein, a specific allergen or another attribute. These quantities are not interchangeable.
- Assess method suitability for the matrix and processing. A nutrition panel or generic conversion factor does not establish this lot’s concentration.
- Set hygiene/microbiological and relevant contaminant specifications based on risk. Food-grade quality alone does not establish suitability for the intended therapeutic use.
- Release raw material only with reviewed evidence and complete linkage to finished batches. Retain a reference sample where the approved plan requires it.
Additional detail
Declare the measurement basis as food mass, mg total protein or an identified analyte, with reference standard and matrix. For extract products assess the relevant protein profile and major allergens. Cross-species transfer needs specific scientific comparability; taxonomy or cross-sensitisation alone is insufficient.
Total protein, major-allergen profile and biological/immunological activity answer different questions. Justify the analytical strategy and any alternative tests for the exact product; a generic protein result does not establish full potency equivalence.
Unconfirmed species, unknown processing or insufficient critical protein data: quarantine.
