Federal Institute for Risk Assessment (BfR): Glycerol in food
The Federal Institute for Risk Assessment (BfR) has clarified in a recent statement that the health reference value for glycerin applies not only to slush ice but also to solid foods.
Glycerin is a sweet-tasting, colorless liquid that is approved as additive E422 for use in foods. It is used, for example, in flavored beverages such as slush ice, but also in solid foods such as baked goods. No legal maximum amount is set; it may be used according to the "quantum satis" principle, i.e. as much glycerin may be used as is necessary for the desired effect.
Glycerin also has medical applications, for example to reduce elevated intracranial pressure.
In 2025 the BfR already investigated whether the intake of glycerin via slush ice beverages is associated with health risks. With the glycerin levels measured in slush ice at that time, small children could already ingest, from a small portion, an amount of glycerin that has an effect on intracranial pressure in medical use. The lowest therapeutically effective dose identified was 250 mg/kg body weight.
In March 2026 the European Food Safety Authority (EFSA) established an acute reference dose (ARfD) for the single consumption of a glycerin-containing drink. This value is 125 mg/kg body weight and indicates how much glycerin can be consumed without a discernible health risk.
With its current statement, the BfR points out that glycerin from solid foods is not absorbed more slowly in the body than from slush ice or other beverages. Therefore, similar effects in the body are to be expected.
Accordingly, from the BfR's point of view both the ARfD value and the lowest therapeutically effective dose are, in principle, also applicable for the assessment of glycerin in solid foods, including fine baked goods.
