This study employed extraction methods, namely acid, alkaline, ultrasonic-assisted, hot-water, and dual enzyme-assisted extraction to extract polysaccharides from Imai (TMIPs), and investigated them for intestinal digestion and fecal fermentation . Furthermore, using fructo-oligosaccharide as a positive prebiotic control, the impact of these TMIPs as carbon sources on the growth of and in liquid culture was assessed. The results showed that all fractions transit through the gastrointestinal tract without degradation.

The directional effect of single-frequency ultrasonic was the cause of the low extraction yield of polysaccharide macromolecule. Thus, a possible solution was to use multi-frequency ultrasonic technology to improve the yield of polysaccharide. Single-frequency (SF), dual-frequency (DF), and three-frequency (TF) ultrasonic extraction were applied to extract polysaccharides of Hovenia dulcis (HDPs).

In this study, accelerated solvent extraction (ASE) technology was applied to extract Hovenia dulcis polysaccharides (HDPs). The polysaccharide yields, physicochemical properties, rheological properties, antioxidant activities, and hypoglycemic effects were compared between ASE-HDPs and hot water extracted polysaccharides (HWE-HDPs). The maximum ASE-HDPs yield was obtained using a response surface method (RSM) with optimized ASE conditions comprising 2 cycles at 130 °C for 23 min.
