Definition of Food-Grade Silicone

Food-grade silicone is a specially developed plastic based on silicone, consisting of the basic components silicon, oxygen, carbon, and hydrogen. It is manufactured so that it can safely come into contact with food and beverages without releasing substances harmful to health. Food-grade silicone is non-toxic, odor-neutral, and BPA-free.

Properties of Food-Grade Silicone

Food-grade silicone stands out due to special properties that make it a popular material for kitchen products and baking molds:

  • Flexible and dimensionally stable: Thanks to its elasticity, baked goods and food can be easily removed from the mold. At the same time, the material retains its shape and does not become brittle or hard like some plastics.
  • High temperature resistance: Silicone remains stable even at extreme temperatures. It is usually suitable for a range of about -40 °C to +230 °C. High-quality silicone molds can even withstand temperatures from -40 °C to +260 °C, in some cases up to +300 °C.
  • Natural non-stick properties: The smooth surface reduces the adhesion of food to the silicone mold. As a result, little or no additional greasing is needed, which makes application easier and processing more efficient.
  • Hygienic and durable: Since silicone has no pores, bacteria and residues can only settle with difficulty. Food-grade silicone resists cleaning agents as well as moisture and water vapor. High-quality food-grade silicone remains reliable for many years even with regular use.

Areas of Application for Food-Grade Silicone

Thanks to its tested food-grade quality, the material is used in numerous areas and meets high requirements for food safety.

Baking Molds and Kitchen Utensils

Food-grade silicone is used for kitchen utensils such as baking molds, whisks, and dough scrapers. Silicone molds allow cakes, muffins, bread, or chocolate to be removed easily without the food sticking. Cooking helpers such as spatulas, dough scrapers, tongs, or pastry brushes are also often made of silicone, as they are heat-resistant and protect sensitive coatings.

Storage and Transport of Food

Silicone is ideal for the reusable storage of food. Flexible silicone lids adapt to various bowl sizes and keep food fresh longer. Foldable silicone boxes save space and are practical for the kitchen, refrigerator, or on the go. Reusable silicone bags can replace conventional plastic bags and are suitable, for example, for snacks or meal prep.

Technical Applications in the Food Industry

Food-grade silicone is also used in professional areas. It is used, for example, for seals in ovens, coffee machines, household appliances, or production plants for food processing. There it ensures reliable sealing, hygiene, and a long service life of the equipment.

Note: In addition to food-grade silicone, there are other special solutions for different industries. Learn more about the diverse silicone applications in our articles on baking plants, the beverage industry, industrial applications, and aviation.

Health Aspects of Silicone Products

Food-grade silicone is a safe alternative to many plastics, as it releases no concerning substances such as BPA or phthalates. However, safety depends on the material quality, since inferior products may contain undesirable additives.

Benefits for Health

  • Free of concerning substances: High-quality, tested silicone contains no hormonally active additives and is therefore especially well suited for contact with food.
  • PFAS-free and chlorine-free: High-quality, tested food-grade silicone is PFAS-free and chlorine-free.
  • High chemical stability: The material remains stable even with repeated heating and cooling and releases no undesirable substances into food.
  • Versatile use: Silicone products such as food molds, kitchen utensils, or storage solutions can replace several products.

Limitations and Important Notes

  • Pay attention to quality: Only high-quality, certified silicone guarantees safe use without undesirable additives.
  • Correct application: The recommended temperature limits should be observed, as extreme heat can affect the material in the long term.
  • Regular inspection: In the case of visible damage such as cracks, deformations, or strong discoloration, the product should be replaced.

Food-Grade Silicone and Conventional Silicone in Comparison

Not every silicone is automatically food-grade. Although food-grade and classic silicone consist of a similar base substance, they differ significantly in their composition, safety, and area of application.

It is particularly important whether the material has been tested and approved for contact with food.

Quality Features of High-Grade Silicone

The market offers a wide selection of silicone products, but the differences in quality are sometimes considerable. For consumers, it is important to recognize high-quality silicone products by certain quality features in order to avoid possible concerns:

    1. Pay attention to quality features: Not every offer on the market meets the same standards. An unusually low price, an intense chemical odor, or a sticky surface can indicate inferior materials or additional fillers.
    2. Transparent material specifications: A high-quality silicone product provides clear information about material quality and suitability for food. Designations such as “food-grade” or “Food Grade” as well as corresponding test marks provide important indications of the product’s safety.
    3. Verifiable quality through testing: Especially in the professional sector, certificates and independent test reports play an important role. They document that the silicone used meets the required standards and is reliably suitable for the intended use.
    4. Check material quality with the pinch test: By gently pressing and twisting, you can get a first impression of the purity of the material. High-quality silicone returns to its original shape without leaving visible white streaks. Such discolorations can indicate inferior additives in the material.
    5. Proper preparation before first use: Before use, silicone should be cleaned thoroughly. Depending on the product, a brief heat treatment can help reduce possible residues from manufacturing.

Quality Assurance through Standards and Certifications for Silicone Products

In order for silicone products to be used safely in the food sector, they must meet certain legal requirements and quality standards. Food-grade silicone must, among other things, pass migration tests to prove its suitability for food contact. In addition, international standards and testing procedures ensure that the material is suitable for food contact.

FDA 21 CFR 177.2600

The requirements of the US Food and Drug Administration (FDA) establish requirements for silicone materials that repeatedly come into contact with food. Among other things, this examines whether possible substance migrations remain within defined limits.

European Requirements

Within the European Union, strict regulations apply to materials with food contact. Regulation (EC) No. 1935/2004 ensures that materials used do not release any components into food that could impair health or alter the quality of the food.

LFGB Testing in Germany

The German Food, Consumer Goods and Feed Code (LFGB) is one of the particularly demanding standards in the area of food contact. Tested products must pass extensive tests, including with regard to substance migration and sensory properties.
