Interference-free determination of carmine in food samples using ultrasonic assisted cloud point extraction coupled with spectrophotometry
Abstract
In this study, a simple, green and cost effective method of extraction
and preconcentration of carmine used as a food additive in some food samples
was developed using ultrasonic assisted cloud point extraction (UA-CPE) before
spectrophotometric determination. Carmine was extracted from the aqueous
solution using polyoxyethylenesorbitan monolaurate (Tween 20) as the extraction
solvent in presence of Ni(II) at pH 6.5. Variables such as pH, amount of metal,
temperature, ultrasonic effect, solvent type, type and concentration of
nanionic surfactant have been optimized in detail. Under the optimum conditions,
the analytical characteristics of the method are as follows; linear working
range 1.5-350 μg L-1; the detection limit, 0.4 μg L-1;
and preconcentration factor, 80. The relative standard deviation (RSD%)
obtained for the 10 μg L-1 concentration (n: 5) of carmine was 3.7%.
Recovery values for two different concentration levels were in the range of
94.8-104.7%. The accuracy and precision of the method were evaluated by intra-
and inter-day studies. Finally, the method has been successfully applied to the
determination of carmine in various foods.
