– Positive list: Approved substances
– Migration testing: Required
– Hygiene certificate: Mandatory
### Safety Testing Protocol
**Challenge Testing**:
– Surrogate contaminants: 3-5 types
– Concentration: 10-100x expected
– Processing: Full scale simulation
– Analysis: GC-MS, LC-MS detection
**Migration Testing**:
– Food simulants: 10% ethanol, 3% acetic acid
– Conditions: Time/temperature accelerated
– Limits: SML (Specific Migration Limit)
– Detection: 0.01 mg/kg sensitivity
### Applications
**Beverage Packaging**:
