The raw chapattiwas immediately placed on an electric hot plate at 280 C 3.0 and baked on one side and then inverted and baked on the other side followed by final baking on the first side. The baking time for the control chapatti was 77 s however the chapattis containing barley flour at level of 28, 56 and 84 g/100 g wheat flour exhibited a baking time of 99, 120 and 165 s, respectively due to differences in dough water absorption. The chapatti was allowed to cool for 10 min at 25 C (80% relative humidity) and then frozen at20 C and freeze dried in a freeze drier (Heto, LL 3000, Denmark) and the freeze dried chapattis were ground in Newport Super Mill (Newport, Australia) and stored at 20 C for further analysis.
