Yield and Physicochemical Properties of Soluble Dietary Fiber Extracted from Untreated and Steam Explosion-Treated Black Soybean Hull

Figure 1

Extraction yield of SDF at different steam explosion (SE) treatment conditions: (a) black soybean hull (500 g) treated by SE at different steam pressures for 80 s and 15% moisture; (b) black soybean hull (500 g) treated by SE at 1.0 MPa and 15% moisture at different times; (c) black soybean hull (500 g) treated by SE at 1.0 MPa and 80 s at different moisture contents. Different letters on the top of a column indicate significant differences (), and the same letters on the top of a column indicate differences that are not significant (); n = 3.
