The present study was designed to prepare samples of jam and sauces of different types and brands collected from Delhi market were subjected to determination for presence of types and concentration of metals using ICP-OES techniques. The mean value of jam indicates that brand 1 has highest concentration of copper (0.04 mg/100g) and lowest was obtained by brand 3 (0.03 mg/100g) and the mean value of jam indicates brand 1 has highest concentration of zinc (0.05mg/100g) and lowest was obtained by brand 3(0.02 mg/100g). Similarly, the mean value of sauces indicates at brand 1 has highest concentration of copper (0.04 mg/100g) and lowest was obtained by brand 3 (0.03 mg/100g) and the mean value of sauces indicates at brand 1 has highest concentration of zinc (0.11mg/100g) and lowest was obtained by brand 3 (0.10 mg/100g). The result indicates that copper and zinc metals were present in low concentration in all brands of jams and sauces.
