Croitoru, M. D. published the artcileDirect HPLC-UV determination of cyclemate, saccharine and aspartame from soft drinks, Recommanded Product: Ethyl 4-hydroxy-6-oxo-6,7-dihydrothieno[2,3-b]pyridine-5-carboxylate, the main research area is cyclamate saccharine aspartame soft drink HPLC UV detection.
Artificial sweeteners were introduced in therapy as sugar substitutes for diabetic patients. Nowadays these substances are widely used for sugar substitution in low calorie drinks and sweets. Most commonly used products to date are saccharine, cyclamate, aspartame, and acesulfam; maximum accepted daily intakes are stated for each one. A simple reverse phase (RP18) HPLC-UV method with direct detection (196 nm) was developed by us in order to measure the concentrations of the three sweeteners. No sample preparation is required, other than dilution Limits of detection are 12 mg l-1, 0.5 mg l-1 and lower than 0.25 mg l-1 for cyclamate, aspartame and saccharine, resp. Concentrations ranged between 113.14-280.07 mg l-1 in the case of cyclamate, 17.96-50.94 mg l-1 for saccharine, and 9.94-296.82 mg l-1 for aspartame.
