Sažetak
Aim and purpose: To find easy, fast, low cost method for determination of melamine in high protein food especially baby food and protein shakes. Ananylize the submitted samples and examine whether they are adulterated by adding melamine. Materials and method: As a material in this paper, samples of baby food and protein shakes were analysed. Manufacturer of all samples are world known brands. Samples were homogenized and after extraction with a suitable organic solvent, DSA-TOF instrument was used to identify the possibility of melamine presence. Results: Separation was achived under 2 min. The detection was performed by DSA-TOF (direct sample analysis-time of flight) in positive polarity mode. Identification was based on accurate mass measurement of protonated ion. The results in this paper are based on a very small number of analyzed high protein food samples. All the analyzed samples were negative for the presence of melamine. Conslusion: It is evident that melamine occurs in high protein food as a adulterant. Many studies have been conducted concerning the illegal addition of melamine as a cheaper substitute for food protein. According to a very small number of analyzed samples, It would be wise to organize a research that will cover a large number different products that can be ordered online and which probably do not undergo official controls.
