Different combinations of fermented vegetables like carrot, radish and cucumber with pear and mango pulps were made separately and were processed. All the sauces prepared were having a constant TSS of 18°B using different combinations of fermented pulp viz., 25, 50, 75 and 100% with fruit pulps of mango and pear. The titratable acidity of carrot, radish and cucumber based sauces ranged from 1.22 to 1.39%. The blending ratio influenced the titratable acidity, Brix-acid ratio, pH and colour of the various sauces. In general, physico-chemical and sensory characteristics of all sauces prepared met the FPO specifications. Carrot with pear pulp based sauce had the highest overall acceptability. Product prepared with 25% radish + 75% pear and sauce with blend of 50% cucumber + 50% pear were preferred to others. Fermented carrot based sauce having blend of 75% fermented carrot + 25% pear was adjudged sensorily as the best. The cost of production of fermented vegetable based sauces (200 ml bottle) ranged between Rs 15.54 and 24.14 and the lowest (Rs 15.54) cost was for radish based fermented sauce.
