Abbreviation for "acceptable daily intake". This is understood to mean the tolerable amount of a substance that a person has throughout his or her lifetime without (probably) negatively or that health can take on disabling consequences. In general, the amounts are determined in animal experiments, with the corresponding substances (pollutants) are supplied via the diet over a longer period of daily. The information is then given in mg / kg body weight. An amount of substance which has not caused any changes in animal experiments is called no-effect-level (NEL).
To calculate the maximum tolerable level 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 persons, extreme deviations from average consumption and other unknown factors. Thus, if a dose of 100 mg / kg body weight and day is considered safe for the animal, the acceptable daily dose in humans would be only 1 mg / kg body weight / day. This is the ADI value. The definition "not specified" states that the tolerable dose could not be determined or has not yet been determined. For many substances, even large amounts do not produce any effects in animal experiments.
The ADI values are published by the WHO (World Health Organization). Various substances in wines and spirits can be harmful from certain quantities and therefore limits are defined. That's 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 non-injurious upper limit". However, no ADI value is given to prevent misinterpretations. There are also codes TWI (Tolarable Weekly Intake) and PTWI (Provisional Tolarable Weekly Intake), as well as the MAK value (Maximum workplace concentration). Whitch amount alcohol is probably not harmful to health is under health described. Listings of relevant substances are available at total extract (Wine ingredients) and Means in winemaking,
