Is Silicone Secure for Baking?

I’ve talked about earlier than that I take advantage of silicone molds to make home made gummy nutritional vitamins, lotion bars, and different family staples. Nevertheless, the point out of silicone molds tends to spark the query, “Is silicone bakeware protected?” Sadly, that is a kind of questions that I often reply by saying: “It relies upon.” Right here’s a extra in-depth rationalization.  

What’s Silicone? 

First, it’s essential to grasp three often-confused phrases: silicon, silica, and silicone. These substances are associated however distinct. Right here’s a short overview of every:

  • Silicon – A pure aspect (image Si and atomic quantity 14). A component can’t break down into smaller particles with out splitting atoms. Silicon is the second most considerable aspect within the earth after oxygen. It’s utilized in many industries, together with electronics (therefore, “Silicon Valley”), photo voltaic vitality, and development.
  • Silica – A compound fabricated from silicon and oxygen (SiO2). It exists in varied varieties, together with quartz, sand, and glass. Silica is a significant element of the Earth’s crust and happens all through nature. It reveals up in glass manufacturing, ceramics, and abrasives. The human physique additionally has a excessive quantity of silica. Some analysis even suggests it could have well being advantages. That’s why I’ll devour it in diatomaceous earth.
  • Silicone – An artificial polymer created by including carbon and/or oxygen to silicon. It might exist as a strong, liquid, or gel. It’s steadily used within the medical discipline. You’ll discover it in medical units like pacemakers, joint replacements, and implants. It’s typically thought of protected for these makes use of and is now used to make cooking utensils and bakeware. 

So, on this article, we’re speaking about silicone, the artificial polymer. It’s “FDA authorized as a food-safe substance” since 1979 and has lengthy been thought of inert. Individuals have extensively used silicone within the kitchen for about 40 years, beginning with silicone spatulas. You’ll discover that not all silicone bakeware on-line is licensed FDA-approved, although. Extra on that later.

Advantages of Silicone Cookware

There’s an excellent cause folks like silicone merchandise like baking pans for the kitchen. Listed below are a couple of of them:


Silicone is a sturdy materials that may face up to repeated use. It’s additionally proof against cracking, fading, and peeling. Individuals usually use silicone baking mats as an eco-friendly different to aluminum foil as a baking sheet liner. The identical goes for cupcake liners. For those who purchase silicone ones, you’re good to go for years to come back! 


Silicone bakeware additionally tends to be extra non-stick than conventional bakeware. That’s particularly necessary for muffin cups and cake pans. Its pure non-stick properties imply it wants little to no greasing or oiling earlier than use. This could scale back the necessity for added fat in baking, saving on elements and prices.

 It additionally merely reduces the frustration of getting baked items persist with the perimeters of the pans. You’re extra prone to finish with an attractive outcome when utilizing a silicone cake pan.


Silicone bake mats and different silicone baking merchandise are often simple to scrub. The flexibleness of silicone bakeware and molds makes it simple to get issues out of them and makes cleanup simpler. Silicone bakeware is often dishwasher protected and straightforward at hand wash with cleaning soap and water. Its clean floor resists staining and doesn’t retain odors. So, it typically stays trying like new for years. 


Silicone is marketed as refrigerator-safe, freezer-safe, and oven-safe, so long as you utilize it in response to the producer’s directions. So, it has many alternative makes use of. Nevertheless, most producers will suggest not placing silicone bakeware immediately on an oven rack. That’s as a result of it could turn into a bit unstable or “floppy” when heated. Setting it on prime of a steel baking tray may also help maintain it steady.

However Is It Secure? 

Individuals usually level out silicone isn’t aluminum, it’s petroleum-free, and doesn’t have BPA or PFAS. However that’s not all there’s to think about. Silicone product manufacturing usually makes use of sure brokers and components within the course of. The query is whether or not these brokers and components stay within the ultimate product you’re taking to the checkout. 

There hasn’t been a lot analysis on the protection of silicone bakeware or silicone molds till extra just lately. That could be because of the enhance in recognition and number of accessible merchandise. 

A 2022 research regarded into these components to see what may leach from silicone cupcake molds into meals. They discovered BHT, a recognized carcinogen, plus two extra possible carcinogens, naphthalene and biphenyl. Additionally they discovered dodecyl acrylate, which irritates the eyes, pores and skin, and lungs.

This research additionally talked about the distinction between low-quality silicone molds and higher-quality “platinum” silicone. These molds are typically costlier however are licensed to be top quality and pure. Excessive-quality silicone merchandise endure an extra warmth remedy to remove chemical residues.

This distinction was measurable. The low-quality silicone exceeded the requirements for off-gassing risky natural compounds (VOCs). The researchers decided these shouldn’t be utilized in contact with meals at increased temperatures. The high-quality silicone cupcake molds met the requirements and had been authorized for high-heat use.

Testing on Silicone

Silicone producers usually conduct security exams internally or by means of third-party laboratories. These exams make sure the silicone merchandise adjust to security requirements and laws. Security testing on silicone bakeware often seems at components like:

  • Materials Composition: Testing to make sure the silicone utilized in bakeware is food-grade and free from dangerous chemical substances or components.
  • Warmth Resistance: Testing to see if it could face up to excessive temperatures with out melting, deforming, or emitting dangerous fumes.
  • Non-Toxicity: Assessing whether or not the silicone leaches any dangerous substances into meals when uncovered to warmth or different situations.
  • Sturdiness: Testing the bakeware’s resistance to ripping, cracking, and degradation over time.
  • Non-Stick Properties: Checking the bakeware’s non-stick coating and making certain it doesn’t have any dangerous substances.
  • Stain and Odor Resistance: Testing to make sure it’s proof against staining and doesn’t retain meals odors.

Nevertheless, silicone’s security at excessive temperatures nonetheless hasn’t been adequately examined, which is why baking with silicone stays controversial. Formally, silicone pans are rated for temperatures under freezing and as much as round 450 levels Fahrenheit or increased, relying on the particular grade of silicone used. So, till just lately, research confirmed high-quality silicone is protected for cooking and baking. 

Potential Risks of Silicone Bakeware

To date, there haven’t been conclusive research on the protection of silicone. Many have assumed it’s protected for the reason that FDA gave it a GRAS score within the late Seventies. Nevertheless, more moderen research point out there could also be toxicity considerations relying on the grade and use. Some potential risks embody:

Leaching of Components 

Decrease-quality silicone bakeware might have fillers that would leach into meals when heated.  These components might embody plasticizers or pigments, which might pose well being dangers if consumed. The research aren’t clear on whether or not that’s the case.

In accordance with a 2016 evaluation:

“[T]he manufacturing of silicone rubber may be very complicated; varied processing brokers are utilized in its manufacture, resembling antioxidants, fillers, vulcanizing brokers and vulcanizing accelerators. Numerous residual components, impurities in uncooked supplies, and newly-formed chemical substances might stay within the ultimate product and migrate into toddler saliva and foodstuff to probably trigger hurt.”

At this level, research are uncertain how usually that is the case. Shopping for higher-quality silicone is probably going price the additional price.

Degradation at Excessive Temperatures 

Whereas silicone is heat-resistant, it might not be appropriate for every type of cooking. Direct publicity to open flames or excessive warmth from broilers might trigger silicone bakeware to degrade, soften, or emit odors. These are the VOCs talked about earlier that always emit from lower-quality silicone molds. 

A 2005 Danish paper reviewed animal research by the Siloxane Analysis Program. They concluded inhaling sure siloxanes might impair fertility and contribute to uterine tumors. The kidneys, liver, and lungs might also be affected.

A 2005 Swiss research decided silicone baking merchandise are solely steady as much as 300 levels Fahrenheit. That’s regarding since most recipes name for baking at 350 Fahrenheit and above.

A 2009 German research discovered that there could also be higher leaching when silicone bakeware is used for high-fat meals. Muffins over 30% fats had increased migration of chemical substances than lower-fat muffins. Meatloaf had a higher leaching than muffins, in response to a 2010 follow-up research.

In 2022, 9 European shopper teams revealed a report on the newest check outcomes of silicone bakeware. They centered on utilizing silicone bakeware at increased temperatures for higher-fat meals. 

After testing 44 silicone molds, they discovered that 23% of them launched contaminants into meals or launched growing quantities from repeat makes use of. Two of them had toxicity ranges above authorized laws. Most of them (82%) had chemical substances of concern, like endocrine disruptors.

This latest report positively provides cause for concern — particularly when utilizing silicone bakeware for keto baking

Potential for Contamination

Silicone bakeware, like all kitchen software, can harbor micro organism or mildew if not cleaned and maintained correctly. Scratches or harm to silicone bakeware might present a breeding floor for micro organism to develop. This might result in meals contamination and even foodborne sicknesses.

Potential for Mislabeling 

In some circumstances, companies might mislabel or falsely promote silicone bakeware. Packaging might say it’s food-grade or heat-resistant when it doesn’t meet security requirements. So, use warning when buying silicone bakeware. Search for respected manufacturers that adjust to regulatory pointers.

These risks aren’t fully confirmed for all silicone manufacturers and merchandise. They’re additionally extra typical at high-temperature use, but it surely’s a good suggestion to be cautious about how and when to make use of silicone.

The best way to Select Safer Silicone

Initially, you in all probability don’t want to fret about oven mitts and ice dice trays. In these circumstances, there’s no direct contact with meals at excessive temperatures. For those who use silicone molds or bakeware, ensure that it’s top quality. You wish to guarantee as a lot as attainable that it doesn’t include fillers or harmful components. Right here’s a guidelines of what to search for:

Meals Grade Silicone  (or Platinum- or Medical-Grade)

Select silicone cookware labeled “food-grade” or “FDA-approved.” Ideally, it must also say “100% silicone.” Meals-grade silicone undergoes rigorous testing to make sure it meets security requirements for meals use. In idea, it shouldn’t have dangerous chemical substances or components. 

“Platinum-grade” makes use of solely the valuable steel platinum in processing, so it’s very pure and the very best grade. Platinum is what’s utilized in hospitals, so “medical-grade” can be good, however you might not discover it on cookware. This kind is utilized in medical units like menstrual cups

Verify for Certifications

Search for cookware licensed by respected organizations or regulatory businesses. In the US, that’s the Meals and Drug Administration (FDA). In Europe, it’s the European Meals Security Authority (EFSA). These organizations regulate meals contact substances, together with silicone utilized in bakeware. They set security requirements and guarantee producers are compliant. Meals-grade silicone certification signifies it meets security and high quality requirements.

Examine for High quality

Look at the standard of the silicone cookware, together with its texture, flexibility, and thickness. Excessive-quality silicone cookware ought to really feel sturdy and sturdy, with a clean floor and no seen indicators of injury or put on. Keep away from silicone cookware that feels flimsy or has a robust chemical scent. These indicators might point out lower-quality supplies or manufacturing processes.

Search for Warmth Resistance 

Be sure that the silicone cookware is heat-resistant and okay to make use of in ovens and freezers. Search for data on the cookware’s temperature vary and keep away from exposing it to open flames or placing it below broilers. Excessive warmth may cause the silicone to degrade or soften.

Learn Critiques and Rankings 

Analysis the silicone cookware model you’re fascinated with. Learn critiques from different prospects to find out about their experiences with the product. Search for their feedback on security, sturdiness, and efficiency to assist inform your choice.

Select Respected Manufacturers (Keep away from Low-cost Imitations)

Established manufacturers usually tend to prioritize security and high quality management. That stated, keep away from low-cost imitations. This cookware could also be produced from inferior supplies or lack security certifications.

What I Do (And The place Silicone May Nonetheless Work)

I nonetheless take into account silicone a lot higher than plastic, which I keep away from in any respect prices. Nevertheless, in terms of cookware and bakeware, I skip the silicone and persist with cookware I do know is protected when heated. That’s the place manufacturers like Caraway and Xtrema are available. 

I usually use Caraway’s bakeware for desserts or muffins. They’ve a full set of cookie sheets, cake pans, and muffin pans which can be toxin-free and straightforward to scrub. Xtrema is one other model of bakeware I take advantage of. Their merchandise are high-quality ceramic and are additionally toxin-free and user-friendly. 

If you wish to strive Xtrema bakeware or cookware, you possibly can use this hyperlink and the coupon code WELLNESS to avoid wasting 15%.

I save my silicone molds for cool-temperature makes use of like:

These are the silicone molds I’ve, which you’ll be able to simply discover on Amazon:

The decrease high quality ones ought to solely be used for cool-temperature and non-food functions like lotion bars and soaps.

Can Silicone Go within the Oven? The Backside Line

Primarily based on that 2022 report, I’ll proceed to make use of most of my silicone molds at low temperatures and within the fridge or freezer. For increased temperature use, I’d persist with high-quality FDA-approved medical-grade or platinum silicone. I’d additionally keep away from utilizing it over 300 levels Fahrenheit. There are higher choices for kitchen instruments, muffin pans, and cookie sheets. 

I want to stay with my Caraway or Xtrema for baking and use wooden, glass, and chrome steel for the stovetop. They’ve been in kitchens for generations and may work properly with somewhat additional oil or elbow grease!
