Abstract:The aim of this study was to analyze ingredients of cereal bars-as indicated on the labels of these products, and to perform a factual analysis of nutritional values indicated therein. The analysis of the nutrients of cereal bars was performed at the laboratory of the Institute BIOR (BIOR Institute of Food Safety, Animal Health and Environment). Results showed that information about nutrients indicated on the labels mostly does not correspond to the actual values, however, they lie within the tolerance range and are lower than the actual determined value. Cereal bars are a source of fiber, but have high sugar content.
