Effects of multi-mode divergent ultrasound pretreatment on the physicochemical and functional properties of polysaccharides from Sagittaria sagittifolia L

The aim of this study was to investigate the physicochemical and functional properties of polysaccharides from Sagittaria sagittifolia L. (SSP), extracted by the assistance of multi-mode divergent ultrasound (SSU), with different frequencies (20, 28, 40 kHz) and various combinations (20/28, 20/40, 28/40, 20/28/40 kHz). The results showed that, compared with hot water extraction, multi-mode divergent ultrasound assistance extraction (MDU) not...
