Aroma Rice Cooker with Outer Steam Tray
High risk; skip until coating is disclosed.
This Aroma cooker has a stainless steel body, but the inner cooking bowl's coating and material remain undisclosed. Without clarity on whether Teflon-type coating, Teflon-family coating, or water-repellent treatments are used, PFAS exposure risk is uncertain.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.
Nonstick coating degradation (if Teflon-type coating-based)
If the inner bowl uses Teflon-type coating, chronic use, high heat, or scratching can fragment the coating. Aroma does not disclose the coating type, so risk cannot be quantified. At temperatures below 260°C (500°F), Teflon-type coating rice cooker bowls present lower concern according to FDA guidance, but confirmation of the exact material is needed.
Aluminum leaching (if bare aluminum inner bowl)
Some Aroma models use uncoated aluminum cooking bowls. Aluminum can migrate into slightly acidic foods or prolonged storage. The outer steam tray material is also unspecified. Without knowing the inner bowl composition, risk level cannot be assessed; contact the manufacturer to confirm material.
Bacterial or mold growth in steam tray
The outer steam tray design can trap condensation and food residue if not cleaned after each use. This is not a material hazard but a maintenance issue. Regular removal, drying, and cleaning of the steam tray prevent microbial colonization.
What’s reassuring
Lead
No recalls or test reports documenting lead or cadmium contamination in Aroma rice cooker bowls are on public record. Modern US-market stainless steel and nonstick coatings are not typically sources of these metals, but undisclosed coatings cannot be fully verified.
Source, ATSDR ↗Stainless steel body corrosion or leaching
The outer housing material is stainless steel, which is stable and does not leach nickel or chromium under normal indoor use. This component poses minimal risk.
The full breakdown
What it's made of and why it matters
Aroma's outer housing is stainless steel, which does not leach metals under normal cooking conditions and resists corrosion. The critical unknown is the inner cooking bowl coating, Aroma does not publicly specify whether it uses nonstick polymers (Teflon-type coating), ceramic-based coatings, or bare aluminum. This omission is the primary safety gap. The outer steam tray material is also not detailed in standard product literature, though stainless steel is typical for this component.
The brand's record and disclosure
Aroma Housewares does not publish detailed material safety disclosures, heavy metal testing results, or PFAS statements on their consumer website. The brand has no major documented recalls for chemical leaching or coating failures in their rice cooker line as of recent public record. However, their silent stance on PFAS and coating chemistry is below the transparency standard of competitors like Cuckoo or Zojirushi, which provide coating specifications. Lack of disclosure does not prove a hazard exists, but it prevents informed comparison.
How it compares in its category
Most modern rice cookers under $100 use either Teflon-type coating nonstick or uncoated aluminum inner bowls. Mid-range brands (Zojirushi, Tiger) openly state their coating type and often certify nonstick safety. Budget competitors including some Aroma models similarly lack detail. Premium induction models often use bare stainless steel bowls, eliminating coating risk entirely. This Aroma unit sits in the transparency gap, functional and reportedly durable, but without the disclosure clarity that allows risk assessment.
If you buy it
Contact Aroma customer service before purchase to request the inner bowl coating name and any relevant safety certifications (e.g., FDA nonstick guidance compliance). Do not use abrasive cleaners or metal utensils on the inner surface, as this can degrade any coating and increase leaching risk. Inspect the bowl annually for scratches, discoloration, or flaking; replace the cooker if damage is visible. Use only water and soft sponges for cleaning, and avoid prolonged soaking of the inner bowl in acidic foods or vinegar solutions.
