Abstract

This paper presents an innovative approach for the digestion of dairy products aimed at determining heavy metal concentrations using atomic absorption spectrophotometry. The present study was conducted to assess the concentration of cadmium in different Yoghurt samples. A total of 80 random samples of dairy products (20 each of sour Yoghurt, sweet Yoghurt, flavoured Yoghurt, and homemade Yoghurt) were collected from different areas of Kota city. For the analysis of heavy metals, a microwave-assisted digestion method was employed for the digestion of the collected samples, which were further analyzed by atomic absorption spectrophotometry. The results obtained revealed that the cadmium content (mean ± SD) in sour, sweet, flavoured, and homemade Yoghurt samples was found to be 0.0201 ± 0.0038, 0.0169 ± 0.0052, 0.0347 ± 0.0096, and 0.0050 ± 0.0041 mg/L respectively. According to these findings, the highest value of cadmium was found in flavoured Yoghurt. The study revealed that the cadmium levels in the samples exceeded the maximum permitted level of 0.0026 mg/L set by the World Health Organization (WHO). This study provides a valuable contribution to the field of food safety analysis, offering a reliable and efficient method for monitoring heavy metal contamination in dairy products and ensuring consumer protection.
