Forever chemicals in the kitchen: what they are and why they matter
Most home bakers know baking soda as the magic powder that lifts cakes and cookies. Far fewer know that another group of chemicals may be quietly tagging along with their food. PFAS (per- and polyfluoroalkyl substances) are often called “forever chemicals” because they don’t readily break down in the environment or in our bodies. They’ve been used in grease-resistant food packaging, nonstick coatings, and other kitchen-adjacent products designed to repel oil, water, and heat. That convenience has a downside: once PFAS get into soil, air, or forever chemicals water supplies, they tend to persist and accumulate. Traditional treatment methods struggle to remove them completely, and many systems simply trap PFAS in filters that are then discarded. For anyone who cares about non toxic cooking tips, safer tools, and cleaner baking water, understanding PFAS in kitchen products is becoming as essential as reading a recipe correctly.
The FIU breakthrough: how baking soda fits into PFAS cleanup science
Researchers at Florida International University, including chemistry professor Kevin O’Shea and PhD candidate Rodrigo Restrepo Osorio, are exploring a new way to tackle PFAS in water that intriguingly involves baking soda. Their work builds on special ring-shaped sugar molecules—think of them as tiny molecular donuts—that can grab PFAS out of water like handcuffs. The challenge has been how to release those chemicals afterward so the cleaning material can be reused. O’Shea’s team realized that a simple shift in pH could act like a door. At neutral pH, the sugar-based material holds PFAS tightly. Make the water more alkaline, even with something as simple as baking soda, and both the material and the PFAS become negatively charged. They repel each other, the “door” opens, and the pollutants are pushed out. This could make PFAS treatment more efficient and sustainable by allowing filtration media to be regenerated instead of thrown away.
No, you can’t just stir baking soda into a glass and fix PFAS
Hearing that baking soda plays a role in this research might tempt you to add a spoonful to your drinking water and hope for cleaner forever chemicals water. That is not how the science works. In the Florida International University system, baking soda is simply a convenient way to adjust pH inside a carefully designed setup that already includes PFAS-grabbing materials. Without those specialized sugar-based structures and controlled conditions, adding baking soda to water will not pull PFAS out. It may change taste or help with some baking soda uses like neutralizing odors, but it won’t magically erase pollution. For home cooks, the key takeaway is conceptual, not a DIY fix: water chemistry can help capture and release contaminants, making professional treatment systems more reusable and potentially more affordable. At home, though, your focus should remain on proven, certified filtration options rather than improvised baking soda treatments.
From popcorn bags to pans: connecting PFAS to everyday cooking choices
PFAS in kitchen products can show up in surprising places. O’Shea’s interest in PFAS began when he looked more closely at microwave popcorn bags his son loved; many such bags were historically coated with PFAS to resist grease and high heat. That concern helped push broader awareness and, more recently, changes such as microwave popcorn brands offering PFAS-free, non-plastic bags and regulatory moves that phase out certain grease-proofing PFAS from food packaging. For home bakers, this connects directly to everyday decisions: which microwave popcorn to buy, how often to rely on disposable grease-resistant packaging, and what kind of nonstick pans to choose. Opting for clearly labeled PFAS-free packaging where possible, using simple glass or stainless-steel bakeware, or even popping corn in a bowl with a plate on top are all non toxic cooking tips that reduce unnecessary contact with these persistent chemicals while still keeping snacks and bakes convenient and delicious.
Practical steps for safer water and cleaner baking at home
So what can home bakers do today while scientists refine PFAS cleanup technologies? First, treat water as a key ingredient. If PFAS contamination is a concern in your area, consider using independently certified filters designed to reduce these compounds, and use that cleaner baking water for drinking, cooking, and bread doughs. Second, be mindful of packaging: look for PFAS-free labels on items like microwave popcorn, baking papers, and take-out containers, or switch to reusable glass, stainless steel, and uncoated parchment where possible. Third, keep exploring baking soda uses where they are proven—deodorizing fridges, gentle cleaning of pans, helping cakes rise—without expecting it to single-handedly solve PFAS issues. Finally, stay curious. As research like the Florida International University work progresses, we’ll likely see more advanced, professionally designed systems that quietly apply these pH tricks behind the scenes, leaving home cooks to focus on flavor and safety in equal measure.
