E900 — Dimethylpolysiloxane

Dimethylpolysiloxane, designated as E900, is a synthetic polymer commonly used as an antifoaming agent in the food industry. It appears as a clear, colorless, viscous liquid and is highly soluble in non-polar solvents. 

Danger Level: 0 — Safe

Purpose in Products

  • Antifoaming Agent: Dimethylpolysiloxane is primarily used to prevent the formation of foam in various food products, including frying oils, soups, and fruit juices. 

Health Considerations

Dimethylpolysiloxane is generally considered safe for consumption. The European Food Safety Authority (EFSA) has established an Acceptable Daily Intake (ADI) of 17 mg per kg body weight per day for E900. 

Impact on Children

Dimethylpolysiloxane is safe for children when consumed in typical dietary amounts. Nonetheless, excessive intake should be avoided to prevent potential digestive issues.

Impact on Taste

Dimethylpolysiloxane is tasteless and odorless, making it an ideal ingredient for various food products without altering their flavor profiles.

Compatibility with Other Additives

Dimethylpolysiloxane is compatible with various other food additives, including sugars and other hydrocolloids. Its water-binding properties make it suitable for use in products requiring moisture retention.

Natural Occurrence

Dimethylpolysiloxane is not naturally occurring in food products; it is synthesized for use as a food additive.

Alternatives and Substitutes

For those seeking alternatives to dimethylpolysiloxane, options include:

  • Silicon Dioxide (E551): Used as an anti-caking agent in powdered foods.
  • Talc (E553b): Employed as an anti-caking agent in various food products.

Regulation

Dimethylpolysiloxane is approved for use as a food additive in many countries, including the European Union, where it is designated as E900. Regulatory bodies such as the European Food Safety Authority (EFSA) have evaluated its safety and concluded that it poses no health concerns when used within established limits. 

Conclusion

Dimethylpolysiloxane (E900) is a versatile and natural food additive with a long history of safe use. Its ability to act as an antifoaming agent makes it valuable in various food products. While generally safe, it is advisable to consume it in moderation to avoid potential adverse effects.
