This showed that the soy flour supplementation account for puffiness and uniform grain size than chickpea. However, corn snacks supplemented with 10/100 g of soy and 10/100 g of chickpea (CSC-10:10) and corn snacks supplemented with 15/100 g of soy and 15/100 g of chickpea (CSC-15:15) showed comparable results (7.44 6 0.52 and 7.34 6 0.44) with corn snack supplemented with soy flour. This might be due to the more expansion of the corn snacks developed with soy flour supplementation.
