The main purpose of this research is to reduce fruit losses, to supply wholesome and safe preserved fruits to utilize during the off-season and develop new value-added products. The present research placed it emphasis on preparing mixed fruits jam products (pineapple and mango) retaining its natural flavor, aroma and a longer shelf-life. Their characteristics such as pH, acidity, viscosity, fibre content, ash content, colour, soluble solid (°Brix), organoleptic properties and shelf-life were determined. Effect of concentration of sugar and effect of storage time at ambient temperature on the quality of mixed fruits jam product were investigated to produce the good quality products.The optimum sugar concentration was 30 ºBrix and maximum sensory score 7.7. Sensory evaluation and microbiological changes of the jam was performed to assess consumers’ likeness and safety for human consumption.
