- Abstract
This study compared the effects of the heat reflux extraction (HRE), microwave enzymatic extraction (MEE) and ultra-high pressure enzymatic extraction (UPE) on the physicochemical, functional properties, antioxidant, hypoglycemic and antibacterial activities of passion fruit peels polysaccharides (PFPPs). Compared with HRE polysaccharides (PFPPs-H), the yield, neutral sugars (CNS), uronic acid (CUA), total phenolics (CTP), total flavonoids (CTF), sulphate content (CS), water solubility (WS), water holding capacity (WHC) and oil holding capacity (OHC) of UPE polysaccharides (PFPPs-U) were increased, but the molecular weight (Mw), protein content (CP) and degree of esterification (DE) were reduced, respectively. Moreover, MEE has a better extraction yield than HRE, but it has not yet reached the level of UPE. Results revealed that PFPPs-U exhibited remarkable antioxidant, hypoglycemic and antibacterial activities, positively correlated with CNS, CUA, CTP, CTF and CS, while lower CP, Mw and DE increased the biological activity, indicating that the UPE is an effective technique for extracting and modifying PFPPs with high biological activity.
