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 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 quick overview of every:
- Silicon – A pure ingredient (image Si and atomic quantity 14). A component can not break down into smaller particles with out splitting atoms. Silicon is the second most plentiful 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 product of silicon and oxygen (SiO2). It exists in numerous types, together with quartz, sand, and glass. Silica is a serious element 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 could actually exist as a stable, liquid, or gel. It’s incessantly used within the medical discipline. You’ll discover it in medical gadgets 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 accredited as a food-safe substance” since 1979 and has lengthy been thought of 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 great motive 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 face up to repeated use. It’s additionally immune to cracking, fading, and peeling. Folks typically use silicone baking mats as an eco-friendly various 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 return!
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 could scale back the necessity for added fat in baking, saving on substances and prices.
It additionally merely reduces the frustration of getting baked items stick with the perimeters of the pans. You’re extra more likely to finish with a fantastic consequence when utilizing a silicone cake pan.
Straightforward-to-Clear
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 usually dishwasher protected and simple handy wash with cleaning soap and water. Its easy floor resists staining and doesn’t retain odors. So, it typically 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 response to the producer’s directions. So, it has many various 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 actually turn into a bit unstable or “floppy” when heated. Setting it on prime of a metallic baking tray will help maintain it secure.
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 ultimate 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 not too long ago. That could be as a result of enhance in recognition and number of out there merchandise.
A 2022 research appeared into these components to see what would possibly 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 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 bear a further warmth remedy to get rid of 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 greater temperatures. The high-quality silicone cupcake molds met the requirements and had been accredited for high-heat use.
Testing on Silicone
Silicone producers sometimes conduct security exams internally or via third-party laboratories. These exams make sure the silicone merchandise adjust to security requirements and rules. Security testing on silicone bakeware often seems to be 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 could actually 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 guaranteeing 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.
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 greater, relying on the particular grade of silicone used. So, till not too long ago, 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 because the FDA gave it a GRAS ranking within the late Nineteen 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 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 may be very advanced; numerous 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 might stay within the ultimate product and migrate into toddler saliva and foodstuff to probably trigger hurt.”
At this level, research are uncertain how typically that is the case. Shopping for higher-quality silicone is probably going price the additional value.
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 usually 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 can also 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 better leaching when silicone bakeware is used for high-fat meals. Muffins over 30% fats had greater migration of chemical compounds than lower-fat muffins. Meatloaf had a better leaching than muffins, in response to a 2010 follow-up research.
In 2022, 9 European shopper teams printed a report on the newest take a look at outcomes of silicone bakeware. They centered on utilizing silicone bakeware at greater 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 undoubtedly provides motive for concern — particularly when utilizing silicone bakeware for keto baking.
Potential for Contamination
Silicone bakeware, like several kitchen software, 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 sicknesses.
Potential for Mislabeling
In some instances, 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 pointers.
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.
Methods to Select Safer Silicone
To begin 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, be sure that it’s prime quality. You need to guarantee as a lot as doable 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 compounds or components.
“Platinum-grade” makes use of solely the valuable metallic 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 sort is utilized in medical gadgets like menstrual cups.
Test 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 scent. These indicators could point out lower-quality supplies or manufacturing processes.
Search for Warmth Resistance
Make 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 beneath broilers. Excessive warmth may cause the silicone to degrade or soften.
Learn Evaluations and Rankings
Analysis the silicone cookware model you’re concerned 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 determination.
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 made out of inferior supplies or lack security certifications.
What I Do (And The place Silicone Might 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 stick with cookware I do know is protected 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 scrub. Xtrema is one other model of bakeware I exploit. 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
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 greater temperature use, I’d stick 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 stainless-steel for the stovetop. They’ve been in kitchens for generations and might work properly with a bit additional oil or elbow grease!
