Study of heavy metal content by AAS in a variety of flavours of Jam samples and its physicochemical characterization
Keywords:
Heavy metals, Atomic Absorption Spectroscopy, Physico chemical, JamAbstract
Different flavours of jam samples were collected from local market and were analysed for the physico chemical parameters like pH, loss on drying, refractive index and acidity calculated as citric acid. Heavy metal such as, Fe, Cu, Zn &Pb were analyses by using atomic absorption spectrophotometer (AAS). pH values ranged from 4.2 to 7.5 , acidity was calculated as citric acid as gm/100gm and it was found to have the values from 0. 22 to 3.4, Moisture from 28.8% to 66.05 % , refractive index value was nearly constant for all the flavours. From among the heavy metals, iron was present in maximum amount ie 2.3462 ppm . Lead was found to have the maximum value of 0.3823 ppm for the strawberry flavor and minimum value was obtained for zinc in mix fruit flavor ie 0.0697 ppm. Copper was found below detectable limit in three flavours and it was 0.0941 ppm for strawberry flavor.
