The increase in the needs of the population for protein causes research on natural and plant products that can be a good substitute for animal proteins. Lentil is a rich source of proteincontaining 20/6 to 31/4% protein. As a result, trying to investigate the physicochemical properties of its protein and replacing animal proteins is considered important. In this research, the optimization of water and oil absorption capacity of Bilesawar green lentils was investigated using the response surface method and Design Expert 11 software. For this purpose, central composite design with three independent variables and 6 central points was used. 20 treatments resulting from the combination of three independent variables pH (8/5-10) and centrifugation time (20-60 minutes) and centrifugation temperature (4-30°C) were evaluated. The results showed the decreasing effect of pH and time on the water absorption capacity, indicating that with the increase of pH and time, the water absorption capacity decreased. Temperature and pH had decreasing effect and time had an increasing effect on oil absorption capacity. Applying the optimized conditions, the oil and water absorption capacity for the optimum point were obtained 1/235 and 1/373, respectively. For validation, optimized predicted and experimented data were compared using T student test (p<0/05).
