摘　　要：[Objectives]This study was conducted to investigate the physicochemical and functional properties of soluble dietary fiber(SDF)from apple pomace.[Methods]Soluble dietary fiber(SDF)from apple pomace was extracted by direct water extraction(W),lactic acid bacteria fermentation(F)and steam explosion(SE)respectively,and the extraction methods and physicochemical and functional characteristics were compared and analyzed.[Results]The solubility,water holding capacities,oil holding capacities and swelling capacities of W-SDF,F-SDF and SE-SDF were(2.13,3.95 and 5.13 g/g),(9.02,13.75 and 15.88 g/g),(2.13,4.08 and 5.11 g/g),and(10.82,14.03 and 15.77 ml/g),respectively.Their emulsifying activity,emulsifying stability and least gelation concentration were(30.28,47.95 and 58.72 ml/100 ml),(37.88,45.25 and 57.13 ml/100 ml),and(12.11,11.25 and 9.87%),respectively.The adsorption capacities of W-SDF,F-SDF and SE-SDF for heavy metals(Pb,As and Cu)in the intestinal environment(pH 7)were(162.7,183.5 and 197.3μmol/g),(132.8,156.7 and 168.9μmol/g),and(57.2,63.5 and 89.2μmol/g)respectively.In the gastric environment(pH 2),they were(72.8,110.5,138.9μmol/g),(82.1,112.5,135.7μmol/g),and(38.9,42.7,55.1μmol/g)respectively.[Conclusions]The study can provide a theoretical basis for functional modification and comprehensive utilization of dietary fiber from apple pomace.
