Yoghurt drink with fruit was made from yoghurt produced from a mixture of buffalos and goats milk at ratio 1:1 and the effectiveness of different fruit types (guava, mango or banana) at level of 5%, 10% or 15% of each on chemical composition, some rheological and organoleptical properties were studied. The results indicated that the total solids (TS), ash, carbohydrate, acidity, NCN/TN, NPN/TN, WPNITN, viscosity and caloric values significantly increased with increasing the ratio of added fruit, while the fat and protein contents were not affected. On the other hand, the addition of fruit significantly decreased the amount of whey separation. The flavor, body and texture of all treatments were significantly improved with increasing the ratio of fruit and using ratio of 15 % was more preferred than 5 or 10 and the mango was preferred than the other fruits.
