I’ve talked about earlier than that I take advantage of silicone molds to make selfmade 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 often 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 ingredient (image Si and atomic quantity 14). A component can’t break down into smaller particles with out splitting atoms. Silicon is the second most ample ingredient within the earth after oxygen. It’s utilized in many industries, together with electronics (therefore, “Silicon Valley”), photo voltaic power, and building.
- Silica – A compound made from silicon and oxygen (SiO2). It exists in varied varieties, together with quartz, sand, and glass. Silica is a serious 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 might 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 may possibly exist as a stable, liquid, or gel. It’s regularly used within the medical area. You’ll discover it in medical units like pacemakers, joint replacements, and implants. It’s usually thought of 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 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 a very good purpose folks like silicone merchandise like baking pans for the kitchen. Listed below are a couple of of them:
Reusable
Silicone is a sturdy materials that may stand 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. Should 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 vital for muffin cups and cake pans. Its pure non-stick properties imply it wants little to no greasing or oiling earlier than use. This may 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 wonderful consequence when utilizing a silicone cake pan.
Straightforward-to-Clear
Silicone bake mats and different silicone baking merchandise are often straightforward to wash. The flexibleness of silicone bakeware and molds makes it straightforward to get issues out of them and makes cleanup simpler. Silicone bakeware is often dishwasher secure and simple at hand 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 employ it in line with the producer’s directions. So, it has many alternative makes use of. Nevertheless, most producers will suggest not placing silicone bakeware straight on an oven rack. That’s as a result of it will possibly develop into a bit unstable or “floppy” when heated. Setting it on prime of a metallic baking tray might help maintain it secure.
However Is It Protected?
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 last product you are 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 as a result of improve in reputation and number of obtainable merchandise.
A 2022 research seemed into these components to see what may leach from silicone cupcake molds into meals. They discovered BHT, a identified 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 bear a further 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 usually conduct security assessments internally or by way of third-party laboratories. These assessments make sure the silicone merchandise adjust to security requirements and rules. Security testing on silicone bakeware often appears at elements 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 stand 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 guaranteeing 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 secure for cooking and baking.
Potential Risks of Silicone Bakeware
To this point, 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 Seventies. Nevertheless, newer research point out there could also be toxicity issues relying on the grade and use. Some potential risks embrace:
Leaching of Components
Decrease-quality silicone bakeware could have fillers that would 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 accordance with a 2016 evaluation:
“[T]he manufacturing of silicone rubber could be very complicated; varied processing brokers are utilized in its manufacture, similar to antioxidants, fillers, vulcanizing brokers and vulcanizing accelerators. Numerous residual components, impurities in uncooked supplies, and newly-formed chemical substances might stay within the last 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 might 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 may additionally be affected.
A 2005 Swiss research 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 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 compounds than lower-fat muffins. Meatloaf had a higher leaching than muffins, in line with a 2010 follow-up research.
In 2022, 9 European client teams printed 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 rules. Most of them (82%) had chemical compounds of concern, like endocrine disruptors.
This latest report positively provides purpose for concern — particularly when utilizing silicone bakeware for keto baking.
Potential for Contamination
Silicone bakeware, like all kitchen software, can harbor micro organism or mould 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.
How one can 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. Should you use silicone molds or bakeware, make certain it’s top 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 must also say “100% silicone.” Meals-grade silicone undergoes rigorous testing to make sure it meets security requirements for meals use. In principle, it shouldn’t have dangerous chemical compounds or components.
“Platinum-grade” makes use of solely the dear 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 businesses. In america, 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 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
Make certain 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 underneath broilers. Excessive warmth could cause the silicone to degrade or soften.

Established manufacturers usually tend to prioritize security and high quality management. That mentioned, keep away from low cost imitations. This cookware could also be constituted of inferior supplies or lack security certifications.
What I Do (And The place Silicone Might Nonetheless Work)
I nonetheless contemplate silicone a lot better than plastic, which I keep away from in any respect prices. Nevertheless, on the subject of 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.
I typically use Caraway’s bakeware for desserts or muffins. They’ve a full set of cookie sheets, cake pans, and muffin pans which might be toxin-free and simple to wash. 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 should utilize 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 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
Based mostly 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 desire 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 might work effectively with just a little further oil or elbow grease!
