| Rubber | Degrades Easily | Low Flexibility | Has fillers and toxins | Melts Easily | Non-recyclable |
Sustainability of Food-Grade Silicone
Food-grade silicone offers reusability, durability, and waste reduction. This makes it different from traditional plastic and rubber types. Since it won’t degrade into microplastics, it is safe for the environment.
It is not biodegradable but well-replaced by single-use plastics. This makes it a sustainable option for modern kitchens and manufacturing industries.
Industry Standards and Certifications
Different regions require Food-grade silicone to meet specific standards. Here are key certifications required in major regions:
- United States (FDA 21CFR177.2600): This certification tests the silicone at specific temperatures to ensure it won’t release any toxic substances.
- European Union ((EC No. 1935/2004): It tests the silicone to see if it can stop the migration of harmful substances into food.
- Germany (LFGB): A strict check to confirm that silicone is free from toxins.
- China (GB4806): A regulation focused on preventing food contamination.
Features and Benefits
- Certified Safe: Meets international safety standards like FDA & LFGB.
- Heat & Cold Resistant: It handles temperatures ranging between -50°C to 250°C.

Choosing the Right Food-Grade Silicone Product
To choose perfect food-grade silicone, make sure it offers transparency, softness, and odorlessness. These features will ensure its quality and safety.
Genuine FDA-approved silicone is transparent and is ideal for making baby products. It has odor-free properties that ensure it won’t smell bad over time. This differentiates it from regular silicone, which turns yellow and smells bad after some time.
Food-grade silicone should be soft but shouldn’t lose its color upon stretching or bending. If the color turns white, the material has fillers and isn’t a genuine food-grade silicone.
Benefits of Using Food-Grade Silicone in Cooking
Food-grade silicone is a safe and versatile upgrade for any kitchen. Here’s why it can make cooking healthy and safe:
- It is non-toxic, so it won’t release chemicals in the food being cooked. It also can’t interact with the food’s odor and taste.
- Food-grade silicone withstands extreme temperatures and is ideal for cooking, baking, and freezing.
- It offers chemical-resistant properties, which means it won’t interact with any food – be it acidic or alkaline – ensuring freshness and purity of the food.
- It is BPA-free and has no phthalates or toxins, which makes it safe. Here is a study on why you should worry about BPA in your food.
Advantages of Using FDA Food-Grade Silicone
- FDA approves food-grade silicone as non-toxic and safe, making it perfect for food storage and babies.
- Genuine food-grade silicone rubber is versatile. You can creatively mold it into shapes and sizes of your own preference.
- Silicon is not similar to rubber and plastic, it has a longer life span because it is durable. This makes it cost-effective and eco-friendly.
- Because it can prevent contaminated interactions with food, it is hygienic to use.
Common Misconceptions about Food-Grade Silicone
Here are some common myths about food-grade silicone:
- Many think that all platinum-cured silicones are food-grade. This isn’t true. Platinum-cured silicone products offer high quality, but that doesn’t always make them food-grade. In fact, tin-cured silicone is not at all safe for food or medical applications.
- People think that Food-grade and medical-grade silicone are the same thing. This isn’t true because Medical-grade silicone undergoes extra testing for body compatibility and is purer than food-grade silicone.
- Another misconception is that food-grade silicone can be used in all food environments. This isn’t true for brewing and baking, where food-grade silicone can interfere with the making processes.
Why is FDA Food Grade Silicone Used in Food Applications?
Below are the top reasons why food-grade silicone rubber is used in food applications:
