Food Grade Silicone: The Food Industry’s All-Round Superstar 

Silicone is a very finicky material. For all its benefits, it is beyond important that you be careful with it whenever you work with the material. 

However, a recent innovation in silicone design has made it possible for certain forms of the material to be safe for consumption. To help understand how this seemingly unconventional material has suddenly become a hit in the cooking space, we will look into food grade silicone more closely.

Food Grade Silicone: What Makes Up This Transformative Material?

So, let’s get to it then – what is food grade silicone?

There is no mystery to what silicone is – a polymer with a broad range of items, but with a major base of oxygen and silicon. Along with materials like hydrogen and carbon, these elements create silicone – one of the most versatile and functional materials on the planet. 

Now, because it comes with hydrogen and carbon as part of its constituents, silicone easily qualifies as a hydrocarbon. And, as many of us know, hydrocarbons shouldn’t be anywhere close to food. The chemical reactions that go into making the product are significantly dangerous, and the last thing you want is to get injured due to contact.  

However, advancements in science have led to the development of a new form of silicone that can come in contact with food without having any issues. Here, you have a polymer that isn’t toxic and which doesn’t have any petroleum-based polymers. 

To be created, food grade silicone goes through several critical manufacturing processes. It is also important for it to meet stringent regulatory and safety requirements – all of which we will look into in later sections. 

Understanding Why Food Grade Silicone Works So Well 

In general, the composition of food-grade silicone doesn’t vary so much from traditional silicone. You have the usual materials, which include: 

  • Silicon (Si): Here is the base element that serves as the backbone of any silicone variant. It offers operational flexibility and functional stability, while also ensuring that the material easily resists heat. 
  • Oxygen (O): With oxygen atoms, you can easily bridge between the primary silicon atoms in the siloxane bond (–Si–O–). The element plays a significant role, ensuring that silicone remains inert and can also optimize heat resistance. 
  • Hydrogen (H): To be fair, hydrogen is only existent in small amounts of silicone. These atoms complete the chemical structure, providing strength and form to the material. 
  • Carbon (C): Carbon is another element that you see in small amounts for any food grade silicon product. Its goal primarily is to offer more operational flexibility and stability to the material, thus improving its properties. 

Food Grade Silicon: Its Chemical Properties 

You might look at the structure of food grade silicone and believe that it is simple. However, this doesn’t mean that the material isn’t strong in its own right. To demonstrate that, here are some of its most interesting chemical properties:

  • Inertness: Generally, food grade silicone doesn’t interact with others. So, if you place it in food, it will barely have any effect. It doesn’t alter the composition of the food, as well as its features – smell, taste, color, etc. 
  • Heat Resistance: Just as the traditional material, any food grade silicone grease or modifications added will be able to resist heat perfectly. 
  • Cold Temperature Resistance: Just as it does when faced with significant heat, food grade silicone will also hold its own when you subject it to significantly low temperatures. Place it in a fridge or freezer, and it will maintain its elasticity and flexibility without becoming brittle. 
  • Water & Moisture Resistance: The food grade silicone material doesn’t let water or moisture in. So, if you’re looking to store your food in cold storage, you can use a food grade silicone material to wrap it and rest assured that water won’t get anywhere in there to breed mold or bacteria. 
  • Chemical stability: You can count on food grade silicone not to be deteriorated by oils, chemicals, fats, and other compounds or elements that are developed as part of the cooking process. It does not degrade or break down when exposed to these substances, ensuring its integrity and safety.
  • Electrical Insulation Capabilities: Another interesting factor that sees food grade silicone lubricant and other associated materials become so popular is its electrical insulation properties. Food grade silicone doesn’t conduct electric current, meaning that it can be used for food industry operations that require electrical applications – sealine, insulation, and more.  
  • UV and ozone resistance: Food grade silicone has good resistance to ultraviolet (UV) radiation and ozone exposure. You could leave it outdoors as much as you want without worrying about degradation from any natural elements. 

Physical Features Of Food Grade Silicone

For a material like food grade silicone, the physical properties matter just as much as the chemical ones when you’re trying to answer the question, “Is food grade silicone safe?”

So, we’ve outlined some of the major features that help this material be as versatile as it is:

  • Material Elasticity: In its very nature, this material provides a ton of elasticity. This means that manufacturers can mold it into whatever shape or size they want, allowing it to fit different purposes. The material is capable of being stretched and even returning to its original form without undergoing any form of deformation. And, as such, it can be used in different industries without any issue.
  • Optimally Soft Texture: You will also notice some softness in the texture of food grade silicone. This makes the material much more tender on food and its surfaces, while also helping it to release mold and reduce the risk of scratching any delicate food surfaces. 
  • Color Properties & Transparency: You won’t have issues finding food grade silicone in different colors. In fact, one of the most fascinating parts about the material is that you can find it in opaque and transparent variants. With the transparent colors, you can enjoy optimal visibility of the food it holds. At the same time, colored silicone can be used to enhance aesthetic features and properties – as well as to differentiate between foods. 
  • Non-Stick Surface: One of the most interesting parts about food grade silicone is that it has a surface that doesn’t stick. So, food placed into a food grade silicone container – such as a baking mat or some other kitchen utensil – won’t stick to it. You don’t need extra greasing or oiling when using food grade silicone for molds, so the process is much more seamless.
  • Thermal Conductivity: For all its benefits, silicone doesn’t conduct heat so well. And, that property extends to food grade silicone. The material comes with low thermal conductivity, which means it does not transfer heat quickly. This property makes it safe to handle hot objects without burning or scalding oneself and provides insulation in applications such as oven mitts and pot holders.
  • Lightweight: With its lightweight build, food grade silicone is easily handled and maneuvered while being prepared or used. You can enjoy ease and comfort, regardless of what you use it for.
  • Resistance to Abrasion and Tear: Food grade silicone is one tough material. It can take significant levels of contact without wearing or tearing, so anything it is used to make will stand the test of time.
  • Water Repellency: As we explained earlier, food grade silicone doesn’t let water in. With food grade silicone tubing or any other material, water or moisture absorption will be cut significantly.

Is Food Grade Silicone Ideal For Everything?

The suitability of food grade silicone for culinary applications can’t possibly be overstated at this point. However, it is important to keep in mind that the material does have its possible shortcomings. Some of those include: 

  • Lack of Rigidity: In general, silicone rubber isn’t so rigid. For applications where you need a stiff and rigid material, this might not be the best bet for you.
  • Lower Thermal Conductivity: Food grade silicone also doesn’t have the best thermal conductivity – especially compared to a few other competing materials; such as rubber. While you can easily handle hot objects using silicone, it also doesn’t efficiently transfer heat during cooking operations. When using silicone bakeware, you might need to adjust cooking temperatures or times to accommodate temperature imbalances.
  • Not Suitable for High-Temperature Frying: Food grade silicone will easily withstand high temperatures. However, we won’t recommend that you use it in direct contact with open flames. This is because extended exposure to overly high temperatures can cause degradation.
  • Potential for Mechanical Damage: While silicone is very durable,it isn’t entirely immune to mechanical damage. Overly sharp objects can tear it, and the material can buckle under excessive force. To wit, we recommend taking care with it to avoid excessive damage. 
  • Potential for Staining: While you enjoy the non-stick properties of food grade silicone, the material can still be prone to staining when you place it in contact with acidic foods or foods with strong colors. Tomato sauce and several other spices could stain it and cause significant discoloration. 
  • Potential for Odor Absorption: Silicone has the risk of absorbing smells from ingredients or foods that have intense scents. This could result in lingering odors that you might have a bit more of a hard time getting out. 

These limitations aren’t necessarily damaging to the prospect of food grade silicone. However, it is important to be careful with the material if you really hope to optimize its use. 


Today, the use of food grade silicone continues to spread. And, it’s entirely understandable why the material would be so popular among culinary experts. Considering that food is one of the most important things in the world, the use of food grade silicone has continued to grow.
