Panasonic SR-JN185 Electric Rice Cooker
Lower concern; stainless steel construction suggests minimal PFAS risk, but lack of brand transparency limits certainty.
The Panasonic SR-JN185 uses a stainless steel inner bowl and aluminum body, materials with lower inherent PFAS risk compared to nonstick coatings. Panasonic has not published any PFAS-related claims or testing for this model. No independent lab testing or recalls are publicly documented for this specific product.

Why this grade
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
The SR-JN185 features a stainless steel inner cooking bowl paired with an aluminum outer housing. Stainless steel is chemically inert at typical rice-cooking temperatures (up to 212°F during the boil phase) and does not leach metals into food under normal use. The aluminum housing does not contact food directly, limiting leaching risk, though older aluminum cookware designs can release aluminum into acidic foods; rice is neutral pH, so this is not a concern for this appliance.
The brand's record and disclosure
Panasonic maintains ISO 9001 quality certifications and has no known recalls for the SR-JN185 related to material safety or leaching. The brand is silent on PFAS use in non-stick coatings and manufacturing, which is common for Japanese appliance makers who rarely publish chemical inventories. No independent testing or consumer complaints regarding heavy metal or coating degradation have been documented for this model in public databases.
How it compares in its category
Stainless steel inner bowls are a premium feature in electric rice cookers; many budget models use non-stick aluminum or coated steel bowls that pose higher leaching and coating-degradation risks. The Panasonic's design avoids both Teflon-type coating (non-stick) fumes and aluminum exposure, placing it in the safer half of the category. Most mid-range competitors (Zojirushi, Cuckoo, Tiger) also use stainless steel, so this is category-standard rather than exceptional.
If you buy it
Use only soft brushes or non-abrasive sponges when cleaning the inner bowl to avoid scratching, though stainless steel is highly resistant to damage. Inspect seals and gaskets annually for discoloration or hardening; silicone gaskets can degrade over 3-5 years of regular use and should be replaced if visibly compromised. Empty the bowl after cooking; prolonged standing water can cause mineral deposits but not safety issues. The aluminum housing should not contact acidic or salty foods directly, though normal steam exposure poses minimal risk.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Aluminum housing corrosion or leaching
Aluminum outer housing does not contact food and operates in a dry-to-steam environment; no documented leaching pathway for this design under normal use.
Stainless steel leaching (nickel, chromium)
Food-grade stainless steel does not leach detectable metal at boiling temperatures. No complaints or recalls for this model indicate any problem; standard food-contact material.
Seal/gasket material degradation (off-gassing or leaching)
Seals and gaskets in rice cookers are typically silicone or rubber; long-term heat exposure can cause degradation and odor, though food safety risk is low if replaced every 3-5 years.
Mineral or limescale buildup in water reservoir
Not a leaching hazard but a maintenance issue; mineral deposits do not affect food safety directly, though they can harbor bacteria if left standing for weeks between uses.
Heating element damage or material exposure (if inner bowl removed improperly)
If the stainless steel bowl is dented or removed incorrectly, the underlying heating plate may be exposed; this does not pose a leaching risk but could cause uneven heating or electrical hazard if water contacts exposed wiring.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
