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. However, the point out of silicone molds tends to spark the query, “Is silicone bakeware safe?” Unfortunately, that is a type of questions that I normally reply by saying: “It depends.” Here’s a extra in-depth clarification.
What is Silicone?
First, it’s essential to grasp three often-confused phrases: silicon, silica, and silicone. These substances are associated however distinct. Here’s a short overview of every:
- Silicon – A pure component (image Si and atomic quantity 14). An 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 power, and development.
- Silica – A compound product of silicon and oxygen (SiO2). It exists in numerous kinds, 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 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 can exist as a stable, liquid, or gel. It’s incessantly used within the medical discipline. 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 approved as a food-safe substance” since 1979 and has lengthy been thought of inert. People 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. More on that later.
Benefits of Silicone Cookware
There’s a superb purpose folks like silicone merchandise like baking pans for the kitchen. Here 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. People usually use silicone baking mats as an eco-friendly various to aluminum foil as a baking sheet liner. The similar goes for cupcake liners. If 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 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 can scale back the necessity for added fat in baking, saving on elements and prices.
It additionally merely reduces the frustration of getting baked items persist with the perimeters of the pans. You’re extra prone to finish with a lovely outcome when utilizing a silicone cake pan.
Easy-to-Clean
Silicone bake mats and different silicone baking merchandise are normally straightforward to wash. The flexibility 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 response to the producer’s directions. So, it has many alternative makes use of. However, most producers will advocate not placing silicone bakeware immediately on an oven rack. That’s as a result of it will probably grow to be a bit unstable or “floppy” when heated. Setting it on high of a metallic baking tray may also help hold it steady.
But Is It Safe?
People usually level out silicone isn’t aluminum, it’s petroleum-free, and doesn’t have BPA or PFAS. But that’s not all there’s to think about. Silicone product manufacturing usually 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. That could also be because of the improve in reputation and number of obtainable 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. They additionally 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. High-quality silicone merchandise bear an extra warmth therapy 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 increased temperatures. The high-quality silicone cupcake molds met the requirements and had been accepted for high-heat use.
Testing on Silicone
Silicone producers usually conduct security checks internally or by way of third-party laboratories. These checks make sure the silicone merchandise adjust to security requirements and laws. Safety testing on silicone bakeware normally seems at elements like:
- Material Composition: Testing to make sure the silicone utilized in bakeware is food-grade and free from dangerous chemical compounds or components.
- Heat Resistance: Testing to see if it will probably 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.
- Durability: 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.
However, silicone’s security at excessive temperatures nonetheless hasn’t been adequately examined, which is why baking with silicone stays controversial. Officially, 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 not too long ago, research confirmed high-quality silicone is secure for cooking and baking.
Potential Dangers of Silicone Bakeware
So far, there haven’t been conclusive research on the protection of silicone. Many have assumed it’s secure for the reason that FDA gave it a GRAS ranking within the late Nineteen Seventies. However, newer research point out there could also be toxicity issues relying on the grade and use. Some potential risks embody:
Leaching of Additives
Lower-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.
According to a 2016 evaluation:
“[T]he production of silicone rubber is very complex; various processing agents are used in its manufacture, such as antioxidants, fillers, vulcanizing agents and vulcanizing accelerators. Diverse residual additives, impurities in raw materials, and newly-formed chemical substances could remain in the final product and migrate into infant saliva and foodstuff to potentially cause harm.”
At this level, research are not sure how usually that is the case. Buying higher-quality silicone is probably going value the additional price.
Degradation at High Temperatures
While silicone is heat-resistant, it will 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. Those are the VOCs talked about earlier that usually emit from lower-quality silicone molds.
A 2005 Danish paper reviewed animal research by the Siloxane Research Program. They concluded inhaling sure siloxanes might impair fertility and contribute to uterine tumors. The kidneys, liver, and lungs may 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 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 response to a 2010 follow-up examine.
In 2022, 9 European client teams printed a report on the most recent check 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 laws. 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 several 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 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. Look 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, nevertheless it’s a good suggestion to be cautious about how and when to make use of silicone.
How to Choose Safer Silicone
First of all, you in all probability 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. If you employ silicone molds or bakeware, be sure it’s prime quality. You wish to guarantee as a lot as doable that it doesn’t include fillers or harmful components. Here’s a guidelines of what to search for:
Food Grade Silicone (or Platinum- or Medical-Grade)
Choose silicone cookware labeled “food-grade” or “FDA-approved.” Ideally, it must also say “100% silicone.” Food-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 very best grade. Platinum is what’s utilized in hospitals, so “medical-grade” can also be good, however it’s possible you’ll not discover it on cookware. This kind is utilized in medical units like menstrual cups.
Check for Certifications
Look for cookware licensed by respected organizations or regulatory businesses. In the United States, that’s the Food and Drug Administration (FDA). In Europe, it’s the European Food Safety Authority (EFSA). These organizations regulate meals contact substances, together with silicone utilized in bakeware. They set security requirements and guarantee producers are compliant. Food-grade silicone certification signifies it meets security and high quality requirements.
Inspect for Quality
Examine the standard of the silicone cookware, together with its texture, flexibility, and thickness. High-quality silicone cookware ought to really feel sturdy and sturdy, with a easy floor and no seen indicators of injury or put on. Avoid silicone cookware that feels flimsy or has a sturdy chemical odor. These indicators could point out lower-quality supplies or manufacturing processes.
Look for Heat Resistance
Make certain the silicone cookware is heat-resistant and okay to make use of in ovens and freezers. Look for info on the cookware’s temperature vary and keep away from exposing it to open flames or placing it beneath broilers. Extreme warmth could cause the silicone to degrade or soften.
Read Reviews and Ratings
Research the silicone cookware model you’re all in favour of. Read evaluations from different clients to find out about their experiences with the product. Look for his or her feedback on security, sturdiness, and efficiency to assist inform your determination.
Choose Reputable Brands (Avoid Cheap Imitations)
Stick to well-known and respected manufacturers with a monitor document of constructing high-quality silicone cookware. Established manufacturers usually tend to prioritize security and high quality management. That stated, keep away from low-cost imitations. This cookware could also be constituted of inferior supplies or lack security certifications.
What I Do (And Where Silicone Could Still Work)
I nonetheless think about silicone a lot higher than plastic, which I keep away from in any respect prices. However, in terms of cookware and bakeware, I skip the silicone and persist with cookware I do know is secure when heated. That’s the place manufacturers like Caraway and Xtrema are available.
I usually use Caraway’s bakeware for desserts or muffins. They have a full set of cookie sheets, cake pans, and muffin pans which can 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.

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 Bottom Line
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 persist 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 choose 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 additional oil or elbow grease!
