E900 - Dimethylpolysiloxan und Methylphenylpolysiloxan

Origin

Dimethylpolysiloxane (also known as dimethicone) and Methylphenylpolysiloxane are silicone-based polymers. Dimethylpolysiloxane is derived from silica (sand) and methyl chloride. Methylphenylpolysiloxane is a similar polymer with phenyl groups incorporated into its structure. These compounds are synthetic and not naturally occurring in food.

Usage

E900 is primarily used as an anti-foaming agent. It is added to foods during processing to prevent or reduce the formation of foam. This is particularly useful in the production of fried foods, jams, jellies, and processed vegetables. It can also be found in cooking oils. The presence of E900 ensures a smoother production process and a more appealing final product by reducing unwanted bubbles and foam. It is also used in some non-food applications such as cosmetics, pharmaceuticals, and industrial processes.

Side Effects

Dimethylpolysiloxane is generally considered safe for consumption in the amounts typically used in food. Regulatory bodies like the EFSA and FDA have evaluated its safety. No significant adverse health effects have been linked to its use as a food additive at permitted levels. Some individuals may experience mild gastrointestinal discomfort, but this is rare. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of "not specified," meaning that, based on available data, the intake of the substance at the levels necessary to achieve the desired technological effect does not represent a hazard to health.

Regulatory Status

Dimethylpolysiloxane (E900) is approved for use as a food additive in many countries, including the United States, the European Union, and Australia. Regulations specify the maximum permitted levels in various food products. These regulations are in place to ensure that the additive is used safely and effectively. The FDA regulates it under 21 CFR 173.340 as a defoaming agent for use in the manufacture of yeast. In the EU, it is subject to Regulation (EC) No 1333/2008 on food additives.
