(A) Microphotographs of primary emulsions I, II, III, IV, and V represent protein content of 0.8 g/100 g, 1.8 g/100 g, 2.8 g/100 g, 3.8 g/100 g, and 4.8 g/100 g). (B) Secondary emulsions (protein content was 3.8 g/100 g; I, II, III, IV, and V represent SBP content of 0.01 g/100 g, 0.02 g/100 g, 0.05 g/100 g, 0.10 g/100 g, and 0.15 g/100 g, respectively). (C) Laccase-treated secondary emulsions (protein content was 3.8 g/100 g; SBP content was 0.10 g/100 g; I, II, III, IV, and V represent laccase content of 2 U/100 g, 4 U/100 g, 6 U/100 g, 8 U/100 g, and 10 U/100 g, respectively). Scale bar represents 10 μm.
