TIGER JNP-1000 Rice Cooker and Warmer
High risk; skip until Tiger discloses inner bowl coating.
The JNP-1000 features an unspecified nonstick inner cooking bowl coating. Nonstick rice cooker coatings commonly use Teflon-type coating or other Teflon-family coating linked to PFAS.

What TIGER JNP-1000 Rice Cooker and Warmer is made of, ingredients and materials
The JNP-1000 features an inner nonstick bowl; Tiger does not publicly specify whether this is Teflon-type coating-based or an alternative Teflon-family coating. The heating element and outer housing are typically stainless steel or aluminum. Nonstick coatings on cookware degrade with thermal cycling and mechanical wear, potentially releasing coating particles or exposing underlying aluminum to food contact, which can leach into rice and water during prolonged cooking and warming cycles.
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 and particle shedding
Tiger does not confirm Teflon-type coating or alternative; unspecified nonstick coatings can flake under repeated heating and mechanical abrasion. Visible coating damage or metallic discoloration indicates active degradation and warrants replacement.
Aluminum leaching from bowl substrate
If the nonstick coating wears through, underlying aluminum in the bowl substrate may contact acidic rice or mineral-heavy water, particularly during extended warming cycles. Rice cookers that sit in warm hold mode for hours daily pose higher cumulative exposure risk.
Teflon-type coating fume risk from overheating
If the nonstick coating is Teflon-type coating-based and the unit is used above safe temperature thresholds or with the lid sealed incorrectly, decomposition fumes (respiratory irritant) are theoretically possible, though rice cooker operating temperatures are typically below Teflon-type coating decomposition point (around 260°C). Risk is low under normal use.
Bacterial growth in crevices and warm settings
Extended warm hold mode (typical feature of this model) creates ideal conditions for bacterial growth if the cooker is not cleaned thoroughly between uses. Not a manufacturing defect but a usage risk related to the product's prolonged heating function.
What’s reassuring
Heating element or housing degradation
No documented safety issues with the electrical components or stainless steel housing of the JNP-1000. Standard rice cooker electrical safety standards apply.
How is this PFAS grade calculated?
The brand's record and disclosure
Tiger Corporation does not publicly disclose the specific nonstick chemistry used in the JNP-1000 inner bowl or provide safety certifications addressing Teflon-family coating content. Tiger has no recorded major product recalls related to nonstick coating failure or leaching for this model line. The brand's silence on PFAS and coating composition limits independent verification of reformulation away from Teflon-type coating.
How it compares in its category
Most modern rice cookers in this price range use either Teflon-type coating or proprietary Teflon-family coating nonstick coatings. Stainless steel inner bowl alternatives exist but are less common and may require additional oil or water to prevent sticking. The JNP-1000 is typical for its category in offering convenience over transparency; higher-end models often include more detailed material specifications.
If you buy it
Avoid abrasive scouring pads or metal utensils that accelerate coating wear; use soft brushes or sponges for cleaning. Do not exceed manufacturer-recommended fill lines or cook times, as prolonged high temperature exposure stresses the nonstick layer. Inspect the inner bowl annually for visible flaking, discoloration, or wear; replace the unit if the coating shows damage. Hand wash rather than dishwasher to reduce thermal shock and mechanical stress on the coating.
