🍏⏩🍎 SFPPy: A Python Framework for Food Contact Compliance & Risk Assessment
🔥A custom AI assistant 🤖 extensively trained on SFPPy 🏋🏻. It helps you explore and use the framework: from the principles of migration modeling ⚙️ to first simulations 📈, regulatory compliance ✅, interpretation 📊, and reporting📝.
No installation. Runs entirely in your browser. Try it now✨:
🟢 Status update: Production-ready with full support for SFPPy notebooks
✅ Complete support for simulation, plotting, curve fitting, and export to PDF/XLSX/CSV
🌍 Integrated databases: EU Regulation Annex I, US FDA FCN lists, Chinese positive lists — ~1300 substances included with toxicological assessment
📦 Runs seamlessly in-browser — no setup needed, fully compatible with modern tablets
🗃️ Files persist in your browser between sessions — drag & drop your own files anytime
🔄 Automatically stays up to date with the latest data and features
🌐 SFPPy-Lite is a lightweight (30 MB), browser-based preview of the full SFPPy framework. It is built on JupyterLite, and runs Python entirely in the browser using Pyodide (WebAssembly-based).
You can explore and use SFPPy’s core functionalities instantly — with no installation required and nothing to configure. Current performance is impressively close to that of a native desktop application.
Warning
💡 Start Here: Launch the notebook demo.ipynb to begin (or watch the video walkthrough).
✅ All components are now operational, including notebooks under 📂Notebooks/, as well as graphical interfaces, simulation, plotting, curve fitting, and export to PDF/XLSX.
⏱️ SFPPyLite runs at approximately half the speed 🌗 of the desktop version. However, all notebooks execute in under one minute. This performance is sufficient for practical use, with the caveat that native in-browser execution (via Pyodide/WebAssembly) imposes some limitations.
🪧🌐 🇪🇺 Annex I of Regulation (EU) 10/2011, 🇺🇸 US FDA Food Contact Notification list and 🇨🇳 Appendices A1-A7 of Standard GB 9685-2016 are included and searchable.
🚩 PubChem substance retrieval is partially functional: the module private.pubchemspy has been adapted for JupyterLite, but write operations may fail due to incompatibilities between Pyodide and IndexedDB, the browser’s internal filesystem.
❌ ToxTree is not supported, as it cannot currently be compiled to WebAssembly.
🗃️ Files (notebooks, scripts, datasets, etc.) are persistently stored in your browser across sessions. Your data remains safe unless using private/incognito mode. You can drop files into the interface or download/export any file as needed.
🧭 Find the platform that fits best your requirements: ease, confidentiality, archiving, assistance.
All usage options are free of charge.

🔮Explore the future. Coding is a language—and with generative AI, we can bridge real-world problems to simulation-ready computer code. Python is the medium of choice, as it remains the most fluent language for AI systems. ╰┈➤Prompts accelerate simulation prototyping and the design of complex case scenarios. Thanks to the abstract nature of this interface, there are no constraints on the level of complexity: it operates independently of the underlying mathematical or numerical methods. |
