Values were mean ± SD of three determinations. Data were expressed as g/100 g dry basis except for moisture content count in (%) and minerals count in (parts per million, ppm). Values of A–D indicate significant difference among each row (P < 0.05). AEDF, dietary fiber obtained by alkali extraction; EHDF, dietary fiber obtained by enzymatic hydrolysis; SEDF, dietary fiber obtained by shear emulsifying assisted enzymatic hydrolysis; TDF, total dietary fiber; SDF, soluble dietary fiber; IDF, insoluble dietary fiber; Particle size distribution D3,2 µm
