I’ve talked about earlier than that I exploit silicone molds to make do-it-yourself gummy nutritional vitamins, lotion bars, and different family staples. Nevertheless, the point out of silicone molds tends to spark the query, “Is silicone bakeware secure?” Sadly, that is a kind of questions that I normally reply by saying: “It relies upon.” Right here’s a extra in-depth clarification.
What’s Silicone?
First, it’s essential to know 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 component (image Si and atomic quantity 14). A component can not break down into smaller particles with out splitting atoms. Silicon is the second most ample component 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 made from silicon and oxygen (SiO2). It exists in numerous varieties, together with quartz, sand, and glass. Silica is a significant part of the Earth’s crust and happens all through nature. It exhibits 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 probably 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 usually thought-about secure 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-about inert. Individuals have broadly 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 a great cause folks like silicone merchandise like baking pans for the kitchen. Listed here are just a few of them:
Reusable
Silicone is a sturdy materials that may face up to repeated use. It’s additionally proof against cracking, fading, and peeling. Individuals typically use silicone baking mats as an eco-friendly different to aluminum foil as a baking sheet liner. The identical goes for cupcake liners. When you purchase silicone ones, you’re good to go for years to come back!
Non-Stick
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 cut back the necessity for added fat in baking, saving on substances and prices.
It additionally merely reduces the frustration of getting baked items keep on with the perimeters of the pans. You’re extra more likely to finish with a phenomenal outcome when utilizing a silicone cake pan.
Straightforward-to-Clear
Silicone bake mats and different silicone baking merchandise are normally 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 usually dishwasher secure and simple handy wash with cleaning soap and water. Its easy floor resists staining and doesn’t retain odors. So, it usually stays trying like new for years.
Multi-Use
Silicone is marketed as refrigerator-safe, freezer-safe, and oven-safe, so long as you utilize it in accordance with the producer’s directions. So, it has many various makes use of. Nevertheless, most producers will suggest not placing silicone bakeware instantly on an oven rack. That’s as a result of it will possibly turn into a bit unstable or “floppy” when heated. Setting it on high of a metallic baking tray will help preserve it secure.
However Is It Secure?
Individuals typically level out silicone isn’t aluminum, it’s petroleum-free, and doesn’t have BPA or PFAS. However that’s not all there may be to think about. Silicone product manufacturing typically makes use of sure brokers and components within the course of. The query is whether or not these brokers and components stay within the closing 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 not too long ago. Which may be because of the improve in reputation and number of accessible merchandise.
A 2022 examine 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. In addition they discovered dodecyl acrylate, which irritates the eyes, pores and skin, and lungs.
This examine additionally talked about the distinction between low-quality silicone molds and higher-quality “platinum” silicone. These molds are typically dearer however are licensed to be prime quality and pure. Excessive-quality silicone merchandise endure an extra warmth remedy to eradicate 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 have been authorized for high-heat use.
Testing on Silicone
Silicone producers sometimes conduct security exams internally or by way of third-party laboratories. These exams make sure the silicone merchandise adjust to security requirements and rules. Security testing on silicone bakeware normally seems at components like:
- Materials Composition: Testing to make sure the silicone utilized in bakeware is food-grade and free from dangerous chemical compounds or components.
- Warmth Resistance: Testing to see if it will possibly 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 circumstances.
- 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 beneath freezing and as much as round 450 levels Fahrenheit or increased, relying on the particular grade of silicone used. So, till not too long ago, research confirmed high-quality silicone is secure 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 secure because the FDA gave it a GRAS score within the late Nineteen Seventies. Nevertheless, newer research point out there could also be toxicity considerations relying on the grade and use. Some potential risks embrace:
Leaching of Components
Decrease-quality silicone bakeware could have fillers that might leach into meals when heated. These components could embrace 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 keeping with a 2016 evaluation:
“[T]he manufacturing of silicone rubber could be very complicated; numerous processing brokers are utilized in its manufacture, corresponding to antioxidants, fillers, vulcanizing brokers and vulcanizing accelerators. Numerous residual components, impurities in uncooked supplies, and newly-formed chemical substances might stay within the closing product and migrate into toddler saliva and foodstuff to probably trigger hurt.”
At this level, research are not sure how typically 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 will not be appropriate for every type of cooking. Direct publicity to open flames or excessive warmth from broilers could 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 examine decided silicone baking merchandise are solely secure as much as 300 levels Fahrenheit. That’s regarding since most recipes name for baking at 350 Fahrenheit and above.
A 2009 German examine discovered that there could also be better leaching when silicone bakeware is used for high-fat meals. Muffins over 30% fats had increased migration of chemical compounds than lower-fat muffins. Meatloaf had a better leaching than muffins, in accordance with a 2010 follow-up examine.
In 2022, 9 European client teams printed a report on the newest take a look at outcomes of silicone bakeware. They targeted 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 rising quantities from repeat makes use of. Two of them had toxicity ranges above authorized rules. Most of them (82%) had chemical compounds 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 every kitchen instrument, can harbor micro organism or mildew if not cleaned and maintained correctly. Scratches or injury to silicone bakeware might present a breeding floor for micro organism to develop. This might result in meals contamination and even foodborne diseases.
Potential for Mislabeling
In some circumstances, companies could mislabel or falsely promote silicone bakeware. Packaging could 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 tips.
These risks aren’t utterly confirmed for all silicone manufacturers and merchandise. They’re additionally extra typical at high-temperature use, however it’s a good suggestion to be cautious about how and when to make use of silicone.
The best way to Select Safer Silicone
To start with, you most likely 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. When you use silicone molds or bakeware, be sure it’s prime quality. You wish to guarantee as a lot as doable that it doesn’t comprise 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 also needs to 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 compounds or components.
“Platinum-grade” makes use of solely the valuable metallic platinum in processing, so it’s very pure and the best grade. Platinum is what’s utilized in hospitals, so “medical-grade” can be good, however you could not discover it on cookware. This kind is utilized in medical units like menstrual cups.
Examine for Certifications
Search for cookware licensed by respected organizations or regulatory companies. 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
Study 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 easy floor and no seen indicators of injury or put on. Keep away from silicone cookware that feels flimsy or has a robust chemical odor. These indicators could point out lower-quality supplies or manufacturing processes.
Search for Warmth Resistance
Ensure that the silicone cookware is heat-resistant and okay to make use of in ovens and freezers. Search for info on the cookware’s temperature vary and keep away from exposing it to open flames or placing it below broilers. Excessive warmth could cause the silicone to degrade or soften.
Learn Opinions and Scores
Analysis the silicone cookware model you’re focused on. Learn critiques from different clients to study 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 Might Nonetheless Work)
I nonetheless contemplate silicone a lot higher than plastic, which I keep away from in any respect prices. Nevertheless, in relation to cookware and bakeware, I skip the silicone and keep on with cookware I do know is secure when heated. That’s the place manufacturers like Caraway and Xtrema are available in.
I typically use Caraway’s bakeware for desserts or muffins. They’ve a full set of cookie sheets, cake pans, and muffin pans which are toxin-free and simple to scrub. Xtrema is one other model of bakeware I exploit. Their merchandise are high-quality ceramic and are additionally toxin-free and user-friendly.
If you wish to attempt Xtrema bakeware or cookware, you’ll be able to 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 keep on 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 favor 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 nicely with somewhat additional oil or elbow grease!
