The industrial processed fruit wastes viz., mango peel, mango seed stone and tomato pomace samples were collected from Mother Dairy processing plant, near Whitefield, Bengaluru. The samples were subjected for biochemical analysis for parameters viz., pH, TSS, acidity and proximate contents of waste samples. The results of biochemical analysis revealed that the pH and TSS varied from 3.42–5.06 and 1.0 – 7.35 respectively between the fruit waste samples. The proximate composition of different fruit wastes revealed that the total protein and fat content were ranged from 4.75 to 18.18 per cent and 1.77 to 6.26 per cent respectively. The moisture content ranged from 5.38 to 8.09 per cent between the wastes. The crude fibre and ash content ranged from 2.65 to 38.10 per cent and 2.45 to 3.61 per cent respectively. The carbohydrate content ranged from 25.76 to 72.99 per cent while tomato pomace showed a very low carbohydrate content compared to mango peel and seed meal. The mineral and pigments contents of industrial processed fruit wastes revealed that the mango peel contains more of iron (230ppm) with carotenoids (4028µg/100g) and Ca (0.42%). Mango seed meal contains more of polyphenols (23.4mg/100g) and potassium (1.49%). Tomato pomace contains more of lycopene (4.4mg/100g) and Ca (4.05%). The results of chemical analysis revealed that the processing of fruit wastes contain more of valuable nutrients which are essential for the development of different value added products.
