Abstract : Mango-Mangifera indica L., Anacardiaceae.is one of the most important fruits marketed in the world rightly called as the 'King of fruits' due to its excellent flavor, delicious taste and higher nutritional value. A large number of products are based on ripe mango fruits such as puree, concentrate, juice, nectar, mango blends, and slices. Mango puree is an important intermediate for the production of mango beverages and leather. With excessive increase in soil and air pollution and use of pesticides and insecticides, we are being faced by a challenge of toxic heavy metal contamination in our fruits and vegetables. Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is being used as the most recent application for the determination of trace level impurities in medicinal plants and fresh fruits and vegetables upto ppt levels. Arsenic, cadmium, mercury, and lead are primary concerned due to their toxicity and potential contaminants in dietary supplements. Current study deals with the comparison of different cultivars of Mango by analyzing the toxic heavy metal contents in the pulp. The simple acid dissolution and microwave digestion were the methods of choice for sample preparation. Microwave digestion had clear advantages over the traditional acid digestion in terms of better recovery of volatile elements and reproducible procedures. The Objective of validation was to develop a method for the determination of heavy metals in mango fruit pulp by using ICP-MS for linearity, precision and accuracy.
