🔧 Function

sfppy.evaluate(material, food, temperature, duration)

📥 Inputs

Name	Type	Description
material	str	Name of the food contact material
food	str	Type of food or simulant (e.g., oliveoil, ethanol)
temperature	float	Exposure temperature in Celsius
duration	float	Contact time in hours

📤 Outputs

Name	Type	Description
migration_profile	dict	Estimated migration vs. time and conditions
compliance_status	bool	True if migration complies with EU regulations

🧠 Assumptions

• Uses partition/diffusion models calibrated on EU regulation.

• Assumes homogeneous contact surface and fixed geometry.

• Temperature influences both diffusion coefficient and partitioning.

⚠️ Limitations

• Only models monolayer materials (use separate model for multilayers).

• Does not account for degradation or chemical reaction during migration.

• Food simulant must match a validated list.
