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. Nonetheless, the point out of silicone molds tends to spark the query, “Is silicone bakeware secure?” Sadly, that is a type of questions that I normally 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 factor (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 factor within the earth after oxygen. It’s utilized in many industries, together with electronics (therefore, “Silicon Valley”), photo voltaic power, and development.
- Silica – A compound fabricated from silicon and oxygen (SiO2). It exists in varied kinds, 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 eat 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 incessantly used within the medical area. 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. Folks 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 superb 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 immune to cracking, fading, and peeling. Folks typically 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!
Non-Stick
Silicone bakeware additionally tends to be extra non-stick than conventional bakeware. That’s particularly essential 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 scale back the necessity for added fat in baking, saving on elements and prices.
It additionally merely reduces the frustration of getting baked items follow the edges of the pans. You’re extra prone to finish with a ravishing outcome when utilizing a silicone cake pan.
Simple-to-Clear
Silicone bake mats and different silicone baking merchandise are normally simple to scrub. The pliability 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 clean floor resists staining and doesn’t retain odors. So, it usually stays wanting like new for years.
Multi-Use
Silicone is marketed as refrigerator-safe, freezer-safe, and oven-safe, so long as you employ it in keeping with the producer’s directions. So, it has many alternative makes use of. Nonetheless, most producers will advocate not placing silicone bakeware instantly on an oven rack. That’s as a result of it may well turn out to be a bit unstable or “floppy” when heated. Setting it on high of a steel baking tray may help hold it steady.
However Is It Protected?
Folks typically 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 contemplate. 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 remaining product you’re taking to the checkout.
There hasn’t been a lot analysis on the security of silicone bakeware or silicone molds till extra lately. Which may be as a result of improve in recognition and number of out there 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 usually dearer however are licensed to be prime quality and pure. Excessive-quality silicone merchandise endure an extra warmth therapy to remove chemical residues.
This distinction was measurable. The low-quality silicone exceeded the requirements for off-gassing unstable natural compounds (VOCs). The researchers decided these shouldn’t be utilized in contact with meals at larger temperatures. The high-quality silicone cupcake molds met the requirements and had been authorized for high-heat use.
Testing on Silicone
Silicone producers sometimes conduct security checks internally or by means of third-party laboratories. These checks make sure the silicone merchandise adjust to security requirements and rules. Security testing on silicone bakeware normally 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 may well 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 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 immune to staining and doesn’t retain meals odors.
Nonetheless, 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 larger, relying on the particular grade of silicone used. So, till lately, research confirmed high-quality silicone is secure for cooking and baking.
Potential Risks of Silicone Bakeware
Up to now, there haven’t been conclusive research on the security of silicone. Many have assumed it’s secure for the reason that FDA gave it a GRAS ranking within the late Nineteen Seventies. Nonetheless, newer 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 may 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 may be very advanced; varied processing brokers are utilized in its manufacture, equivalent to antioxidants, fillers, vulcanizing brokers and vulcanizing accelerators. Various residual components, impurities in uncooked supplies, and newly-formed chemical substances may stay within the remaining product and migrate into toddler saliva and foodstuff to doubtlessly 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 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 may 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 larger migration of chemical compounds than lower-fat muffins. Meatloaf had a higher leaching than muffins, in keeping with a 2010 follow-up research.
In 2022, 9 European client teams printed a report on the most recent check outcomes of silicone bakeware. They centered on utilizing silicone bakeware at larger 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 current report positively offers purpose for concern — particularly when utilizing silicone bakeware for keto baking.
Potential for Contamination
Silicone bakeware, like all kitchen device, can harbor micro organism or mildew if not cleaned and maintained correctly. Scratches or harm to silicone bakeware may present a breeding floor for micro organism to develop. This might result in meals contamination and even foodborne sicknesses.
Potential for Mislabeling
In some instances, 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, however it’s a good suggestion to be cautious about how and when to make use of silicone.
Find out how to Select Safer Silicone
To start with, you most likely don’t want to fret about oven mitts and ice dice trays. In these instances, there’s no direct contact with meals at excessive temperatures. For those who use silicone molds or bakeware, ensure that it’s prime quality. You need to guarantee as a lot as potential 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 also needs to say “100% silicone.” Meals-grade silicone undergoes rigorous testing to make sure it meets security requirements for meals use. In concept, it shouldn’t have dangerous chemical compounds or components.
“Platinum-grade” makes use of solely the dear 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 also be good, however chances are you’ll not discover it on cookware. This sort is utilized in medical units like menstrual cups.
Verify for Certifications
Search for cookware licensed by respected organizations or regulatory businesses. In the USA, 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 clean 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 might 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 beneath broilers. Excessive warmth may cause the silicone to degrade or soften.
Learn Evaluations and Rankings

Established manufacturers usually tend to prioritize security and high quality management. That mentioned, keep away from low-cost imitations. This cookware could also be made out of inferior supplies or lack security certifications.
What I Do (And The place Silicone May Nonetheless Work)
I nonetheless think about silicone a lot higher than plastic, which I keep away from in any respect prices. Nonetheless, in terms of cookware and bakeware, I skip the silicone and follow 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 can be toxin-free and simple 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.

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
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 larger temperature use, I’d follow 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 effectively with a bit additional oil or elbow grease!
