Abstract
According to the literature all flour types have different composition. This is important for people, who have allergy or disease caused by food, e.g. celiac disease. Usually flour quality is considered by determining gluten content, but it is also important to identify other constituents like minerals and amino acids. Comparison of minerals and amino acids in different flours was performed between three types of flour. Wheat, rye and oat flour was chosen by its popularity in all world cuisines. Capillary zone electrophoresis method with capacitance-to-digital based contactless conductivity detector was optimized and used for determination of inorganic cations and amino acids and comparison of different types of flours. Optimized conditions were following: 0.5 M acetic acid was used as a background electrolyte. 0.05 grams of flour were extracted by 50 % of propyl alcohol solution. Analysis in fused silica capillary were irreproducible, therefore it was decided to coat internal wall of the separation capillary. Mentioned procedure improved analytical data significantly.
