Soft drinks’ composition as a theme of educational experiments for upper-secondary schools
Original language description
The article is focused on development of thin-layer chromatographic methods for analysis of soft drinks (N = 11) with the aim to propose novel didactical aids for introduction of suitable chemical experimental tasks in teaching chemistry at general secondary schools. These tasks are oriented to analytical identification of four common chemical substances: L-ascorbic acid, caffeine, sorbic acid and taurine. The selected compounds induce specific effects in the human body such as stimulation of the central nervous system and are also broadly utilized as taste additives, antioxidants, or stabilizers in various foods. The proposed experiments are designed for further didactical evaluation.
