[Cariogenic carbohydrates in maltodextrins, glucose syrups and maltodextrin-containing infant tea].

Five maltodextrins and five corn syrups each, seven instant teas containing maltodextrin and one tea produced on a protein-base were analysed for fermentable carbohydrates using enzymatic analyses test combinations and a spectrophotometer. Analysis of the maltodextrins and glucose syrups demonstrated the heterogenicity of this group of substances and also some incompleteness in the declaration of maltose, maltotriose and glucose, sugars typically contained in these products. In standard samples of the instant teas cariogenic sugars were found in concentrations up to 0.7%. As these sugars were not declared in any of the products, the consumer is not able to assess the cariogenic potential of the ingredient maltodextrin. The intake of products containing maltodextrins or corn syrups must lead to an uncontrolled sugar consumption.
