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. 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 clarification.
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 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 ample ingredient within the earth after oxygen. It’s utilized in many industries, together with electronics (therefore, “Silicon Valley”), photo voltaic vitality, and building.
- Silica – A compound made from silicon and oxygen (SiO2). It exists in varied 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 eat it in diatomaceous earth.
- Silicone – An artificial polymer created by including carbon and/or oxygen to silicon. It may well exist as a strong, liquid, or gel. It’s incessantly used within the medical subject. You’ll discover it in medical gadgets like pacemakers, joint replacements, and implants. It’s typically 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 authorised as a food-safe substance” since 1979 and has lengthy been thought-about inert. Folks 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 motive folks like silicone merchandise like baking pans for the kitchen. Listed here are a couple of of them:
Reusable
Silicone is a sturdy materials that may face up to repeated use. It’s additionally proof against 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. When you 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 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 substances and prices.
It additionally merely reduces the frustration of getting baked items stick with the perimeters of the pans. You’re extra prone to finish with a fantastic end result when utilizing a silicone cake pan.
Simple-to-Clear
Silicone bake mats and different silicone baking merchandise are normally straightforward to scrub. The flexibleness of silicone bakeware and molds makes it straightforward to get issues out of them and makes cleanup simpler. Silicone bakeware is usually dishwasher secure and simple 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.
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 various makes use of. Nonetheless, most producers will advocate not placing silicone bakeware immediately on an oven rack. That’s as a result of it could possibly turn into a bit unstable or “floppy” when heated. Setting it on high of a metallic baking tray may help maintain it steady.
However Is It Secure?
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 may be 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 closing 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 just lately. That could be because of the enhance in reputation and number of obtainable merchandise.
A 2022 examine appeared 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 costlier 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 greater temperatures. The high-quality silicone cupcake molds met the requirements and had been authorised for high-heat use.
Testing on Silicone
Silicone producers usually conduct security checks internally or by third-party laboratories. These checks 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 substances or components.
- Warmth Resistance: Testing to see if it could 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.
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 beneath freezing and as much as round 450 levels Fahrenheit or greater, relying on the precise grade of silicone used. So, till just lately, research confirmed high-quality silicone is secure for cooking and baking.
Potential Risks of Silicone Bakeware
Thus far, 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 score within the late Nineteen Seventies. Nonetheless, more moderen research point out there could also be toxicity issues relying on the grade and use. Some potential risks embody:
Leaching of Components
Decrease-quality silicone bakeware could have fillers that might leach into meals when heated. These components could 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 keeping with a 2016 evaluation:
“[T]he manufacturing of silicone rubber could be very advanced; varied processing brokers are utilized in its manufacture, resembling antioxidants, fillers, vulcanizing brokers and vulcanizing accelerators. Various 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 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 might not be appropriate for all sorts 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 might also be affected.
A 2005 Swiss examine 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 examine discovered that there could also be higher leaching when silicone bakeware is used for high-fat meals. Muffins over 30% fats had greater migration of chemical substances than lower-fat muffins. Meatloaf had a higher leaching than muffins, in line with a 2010 follow-up examine.
In 2022, 9 European client teams revealed a report on the most recent check 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 substances of concern, like endocrine disruptors.
This latest report positively offers motive 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 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.
How you can Select Safer Silicone
To begin 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 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 principle, it shouldn’t have dangerous chemical substances 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 could not discover it on cookware. This kind is utilized in medical gadgets like menstrual cups.
Verify for Certifications
Search for cookware licensed by respected organizations or regulatory companies. 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
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 harm or put on. Keep away from silicone cookware that feels flimsy or has a sturdy chemical odor. These indicators could point out lower-quality supplies or manufacturing processes.
Search for Warmth Resistance
Be sure 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.

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 Might Nonetheless Work)
I nonetheless think about silicone a lot higher than plastic, which I keep away from in any respect prices. Nonetheless, with regards to cookware and bakeware, I skip the silicone and stick 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 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
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 desire 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 effectively with a bit further oil or elbow grease!
