Abstract: One-factor-at-a-time and orthogonal array design methods were applied to optimize the extraction of yellow pigment from corn bran by cellulase hydrolysis followed by microwave treatment. The optimal extraction conditions were obtained as follows: 95% acidified ethanol at pH 5.5 as extraction solvent at a material/liquid ratio of 1:8 (g/mL), and 400 W microwave irradiation for 50 s before cellulase hydrolysis at 50 ℃ for 90 min.

Key words: corn bran, pigment, extraction, microwave, cellulase
