The authorised claims, word for word

Authorised claim	Conditions of use
Consumption of foods/drinks containing <name of all used non-fermentable carbohydrates> instead of fermentable carbohydrates contributes to the maintenance of tooth mineralisation.	In order to bear the claim, fermentable carbohydrates (1) should be replaced in foods or drinks by non-fermentable carbohydrates (2) in such amounts that consumption of such foods or drinks does not lower plaque pH below 5,7 during and up to 30 minutes after consumption. (1) Fermentable carbohydrates are defined as carbohydrates or carbohydrate mixtures as consumed in foods or beverages that lower plaque pH below 5,7, as determined in vivo or in situ by plaque pH telemetry tests, by bacterial fermentation during and up to 30 minutes after consumption. (2**) Non-fermentable carbohydrates are defined as carbohydrates or carbohydrate mixtures as consumed in foods or beverages that do not lower plaque pH, as determined in vivo or in situ by plaque pH telemetry tests, below a conservative value of 5,7 by bacterial fermentation during and up to 30 minutes after consumption.
