In this study the effect of chickpea flour in three ranges of (0, 1.5 & 3%) and storage time in three ranges of (1, 11 & 21 days) on survival of lactobacillus paracasei and qualitative properties of fruit yogurt containing 15% apple puree was investigated using response surface method (RSM). The statistical analysis of the results showed that with increasing of chickpea flour up to 0.5%, lactobacillus paracasei viability increased but with increasing of flour more than this amount the bacterial count decreased significantly (P<0.05). The bacterial count decreased during storage (P<0.05). The addition of chickpea flour decreased pH, moisture content, syneresis and increased acidity, ash and apparent viscosity significantly (P<0.05). During storage pH and moisture content decreased and apparent viscosity increased (P<0.05). In sensorial evaluation of samples the addition of chickpea flour decreased the flavor score and improved consistency score (P<0.05). In conclusion, using of 2.36% of chickpea flour and with storage period of 9 days was determined as optimum conditions.
