After heat treatment by control (unprocessed), steaming, HTHP and extrusion, the corn-wheat composite steamed bread fermented by yeast and sourdough were expressed as Control-YF, Steaming-YF, HTHP-YF, Extrusion-YF, Control-SF, Steaming-SF, HTHP-SF and Extrusion-SF, respectively.

Results were presented as mean ± standard deviation. Different letters in the same column in the table show significant differences (P < 0.05, n = 3).

H/D, height diameter ratio; SV, specific volume.
