Effect of extraction method on the chemical profiles and bioactivities of soybean hull polysaccharides

The yields, properties, and bioactivities of polysaccharides extracted by three methods from soybean hulls (SSCPs) were evaluated: hot water extraction (H‐SSCP), microwave‐assisted ammonium oxalate extraction (A‐SSCP), and microwave‐assisted sodium citrate extraction (S‐SSCP). A‐SSCP gave the highest yield of polysaccharides (9.3 ± 0.5%) although all three products had similar physicochemical characteristics and FT‐IR spectra. A‐SSCP and S‐SSCP...
