Case Study: Potassium Bitartrate (CAS 868-14-4)

This natural salt, derived from winemaking byproducts, gained approval as:

• ✔ Acid regulator – Balances pH in wines and baked goods
• ✔ Stabilizer – Prevents crystallization in sugar syrups
• ✔ Label-friendly – Recognized as GRAS (Generally Recognized as Safe) by FDA

Its approval relied on:

• Safety data (low toxicity, no allergenic concerns)
• Functional benefits (improves texture in foods)
• Natural origin (aligns with clean-label trends)

Conclusion

Becoming a food additive requires rigorous safety proofs, functional validation, and compliance with regional regulations. Substances like Potassium Bitartrate exemplify how scientific and regulatory scrutiny ensures consumer safety while meeting industry needs.
