摘要
Fluoride content in bottled wines of the different types and areas of the Canary Islands was studied by direct potentiometry with a fluoride specific electrode using the addition method. We found a mean concentration of 0.15 mg/l and a standard deviation of 0.068. The biggest concentration of fluoride ion (0.50 mg/l) was found in a white wine of Tacoronte-Acentejo. However, all wines analyzed presented concentrations of fluoride lower than the maximum allowed by the International Office of the Vineyard and the Wine. So, the contribution of the Canarian wines to the fluoride daily intake does not represent any risk of fluorosis. Also these concentrations have no influence on the production process of the wine.
