Note: data are means of triplicate ± standard deviation. Values in the same column with different letters are significantly different (). Values in the same column with the same letters are not significantly different (); n = 3. A: SE treatment of black soybean hull; B: untreated black soybean hull. CE: cellulose; HE: hemicellulose; LI: lignose; WHC: water-holding capacity; SC: swelling capacity; WBC: water-binding capacity; OHC: oil-holding capacity; SE: steam explosion. SE treatment conditions: pressure, 1.0 MPa; moisture, 15%; treatment time, 80 s.
