What Grades of Food Silicone Rubbers Are FDA Approved？

Food silicone is a safe material widely used in the food industry is resistant to high temperatures, non-toxic and odorless, and is commonly used in tableware, baking utensils, products that for babies, and so on. To ensure safety, silicone formulas must pass rigorous evidence approved by the U.S. Department of Health and Human Services. Food and Drug Administration (FDA). So, what are the labels of FDA-approved food silicones? Let’s take a quick look.


Basic requirements for FDA food grade silicone
The FDA has very strict requirements in food-grade silicone. First of all, this silicone material must be non-toxic and safe, and not use chemicals in food or release harmful substances. Second, food-forming silicone must be resistant to high temperatures and corrosion to ensure that it will not deteriorate during high-temperature cooking or long-term use.


Different types of food grade silicone
According to various applications, food-grade silicones can be roughly classified as follows:

1. Liquid silicone (LSR) .
Liquid silicone is an extremely soft and durable material commonly used in baby nipples, cell phone cases, utensils and other food contact products. This silicone can be injection molded into uniformly hard shapes and has good antimicrobial properties.

2. High-density silicone (HTV) .
Solid silicone is often used in high-energy products that come into contact with food, such as processors, bakeware, cake molds, and more. It has high thermal resistance and strength, is suitable for long-term use, and will not release harmful substances due to high temperatures.



3.Medical grade silicone
Although primarily used in pharmaceuticals, some high-demand food contact products also use medical silicone. It has high levels of purity and safety, so it is used in specialized food processing and storage areas as well.


FDA certification standards
FDA certification standards are primarily based on United States Code of Federal Regulations (CFR) Chapter 21 Section 177.2600, which defines food ingredients and manufacturing requirements. The FDA certification not only targets silica gel itself, but also tightly controls its manufacturing process to ensure that the product won't harm human health due to impurities during manufacturing or additives due to improper use.


How to identify an FDA-approved dietary source of silicone?
When choosing a silicone-based food product, you can confirm from the following criteria whether it meets FDA standards:

1. Check labels: Standard silicone formulas will be clearly marked with "FDA certified" or "FDA compliant."
2. Verify the manufacturer: Choosing a good reputable factory can better ensure the quality and safety of the product.
3. Review the certifications: If you have any questions about the product, you can ask the manufacturer to provide appropriate FDA certifications to further confirm the safety of the product.


in conclusion
FDA-approved food-grade silicones are widely used in food-contact areas for safety and stability reasons. When purchasing silicone food products, be sure to choose FDA-approved products to better protect food safety and health.
