Abbreviation for "acceptable daily intake". This is understood to be the tolerable amount of a substance that a person has daily without (probably) negative or that throughout his lifetime health can have adverse effects. As a rule, the quantities are determined in animal experiments, with the corresponding substances (pollutants) being supplied daily through food over a longer period of time. The information is then given in mg / kg body weight. A quantity of substance that has not caused any changes in animal experiments is called a no-effect level (NEL).
To calculate the maximum tolerable amount in humans, this value is divided by 100. This "safety factor 100" is chosen arbitrarily. It should take into account unknown risks, such as particularly sensitive people, extreme deviations from average consumption and other unknown factors. If a dose of 100 mg / kg body weight and day is classified as harmless for the animal, the acceptable daily dose in humans would only be 1 mg / kg body weight / day. This is the ADI value. The definition "not specified" means that the tolerable dose could not be determined or has not yet been determined. Because with many substances, even large quantities have no effects in animal experiments.
The ADI values are published by the WHO (World Health Organization). Different substances in wines and spirits can be harmful from certain quantities and therefore limit values are defined. These are, among other things acetaldehyde. allergens. lead (see also under heavy metals ) cadaverine. diammonium phosphate. acetic acid. proteins / gluten. ethyl carbamate. isoamylamine. histamine. caffeine. methanol. Ochratoxin A. phenylethylamine. putrescine. sulphurous acid. silver chloride. thiamine and tyramine,
With regard to alcohol quantities, the WHO publishes a “presumably not harmful upper limit”. However, no ADI value is given to prevent incorrect interpretations. There are also the codes TWI (Tolarable Weekly Intake = tolerable weekly intake) and PTWI (Provisional Tolarable Weekly Intake = temporarily tolerable weekly intake), as well as the MAK value (Maximum workplace concentration). Whitch amount alcohol is probably not harmful to health health described. There are lists of relevant substances under total extract (Wine ingredients) and Means in winemaking,
