Ammonium chloride or other salts are often used in the production of licorice. Ammonium chloride is chemically identical to ammonium chloride.
The ammonium chloride content in licorice must be marked: more than 20 g ammonium chloride/kg = adult licorice - no children's licorice!
with ammonia content between 44.9 and 79.9 g/kg = extra strong, adult licorice - not children's licorice!
with ammonia content over 80g/kg Warning: "Excessive consumption may be harmful to health, especially in people with kidney disease".
Dose restriction: According to the Federal Institute for Risk Assessment (BfR) maximum glycyrrhizin 100 mg/day ! means for children's licorice: maximum 100 grams per day
for adult licorice (0.2 grams of glycyrrhizin per 100 grams): less than 50 grams per day
Strong licorice (0.4 grams of glycyrrhizin per 100 grams): maximum 25 grams per day
