CR-0655F Micom Rice Cooker
Insufficient data on inner bowl coating; contact Cuckoo for specifics.
Cuckoo does not disclose inner bowl coating composition or PFAS risk. Rice cooker inner surfaces often use nonstick coatings; verify coating type directly with manufacturer before purchase.

What CR-0655F Micom Rice Cooker is made of, ingredients and materials
The CR-0655F has a stainless steel external body but an inner cooking bowl with an unspecified coating, which is the critical unknown. The coating material directly contacts food at high heat during cooking, making its composition essential for safety assessment. Without disclosure of whether the coating is non-stick (Teflon-type coating-based), ceramic, or another polymer, leaching risk cannot be properly evaluated. Stainless steel itself is inert and low-concern, but the bowl coating is where chemical migration could occur.
What’s concerning
Non-stick, chemistry undisclosed
Marketed as non-stick without stating the coating chemistry.

No PFAS disclosure
No public statement from the brand about PFAS in this product.
Coating degradation and metal leaching
Because the inner bowl coating is unspecified, wear from repeated heating and stirring may expose underlying steel or base material. If the coating is polymeric (such as epoxy or Teflon-type coating), it can degrade over years, potentially releasing monomers or allowing aluminum or other metals to leach into food.
Non-stick polymer fume release (if Teflon-type coating or similar)
If the inner bowl is coated with Teflon-type coating or similar Teflon-family coating, overheating above safe limits (typically above 260°C) can release polymer fumes; rice cookers normally operate well below this, but malfunction or operator error could cause concern. Without coating confirmation, this risk cannot be ruled in or out.
Thermal cycling stress on coating adhesion
Repeated heating and cooling cycles can cause unspecified coatings to crack, blister, or delaminate, especially if the adhesion layer is not disclosed. Once coating integrity is compromised, food contact with bare substrate becomes a concern.
What’s reassuring
Aluminum leaching (if aluminum-based substrate)
The product description specifies stainless steel body; no evidence suggests an aluminum substrate. If the inner bowl substrate is aluminum rather than steel, acidic or salty foods could promote leaching, but this is not confirmed for this model.
Formaldehyde / VOCs
No public reports of VOC or formaldehyde off-gassing from this model have been documented. Standard food-contact coatings used in rice cookers are unlikely to contain significant formaldehyde, but unspecified materials cannot be fully ruled out without testing.

The brand's record and disclosure
Cuckoo has not publicly disclosed PFAS testing data or stance on PFAS "forever chemicals" in their cookware lines, earning a poor PFAS safety grade of 35/100. The company provides no specification sheet detailing the inner bowl coating material, a significant transparency gap for a product category where coating composition directly affects food safety. No major product recalls or established chemical contamination incidents are on record for this model. Independent third-party certifications (e.g., FDA, NSF) specific to this model are not readily documented in public sources.
How it compares in its category
Rice cookers vary widely in inner bowl treatment; common alternatives include bare stainless steel (inert but slower heating), ceramic-coated steel (generally lower concern but fragile), and non-stick polymer coatings (Teflon-type coating-based or fluorine-free alternatives). The CR-0655F's refusal to specify its coating puts it at a transparency disadvantage compared to brands that openly state 'Teflon-type coating-free' or 'ceramic-lined' designs. Budget-tier rice cookers often obscure coating materials; premium brands typically provide material datasheets. Without specification, this model sits in a middle-market zone of ambiguous disclosure.
If you buy it
Contact Cuckoo customer service directly and request written confirmation of the inner bowl coating material before committing to purchase. Once in use, avoid extended storage of acidic foods (vinegar, tomato-based dishes) in the cooker, as unidentified coatings may have variable acid resistance. Do not use at temperatures above the cooker's specified operating range (typically 100-110°C during operation); overheating can accelerate coating degradation or off-gassing. Inspect the inner bowl annually for scratches, peeling, or discoloration; if damage is visible, discontinue use and consider replacement or a model with disclosed, certified coating materials.
