It demonstrated antimicrobial activity against both Gram-positive and Gram-negative pathogens, and showed the ability to inhibit biofilm formation in <em>Staphylococcus aureus</em> (76.61%) and <em>Escherichia coli</em> (13.64%). Furthermore, the EPS exhibited DPPH free radical scavenging (92.25%), hydroxyl radical scavenging (87.82%), and reducing power capacity (3.1 mM/L), which indicate its substantial antioxidant potential. Additionally, the EPS sample demonstrated significant anti-inflammatory activity (75.79 %) and moderate oil emulsifying capacity with an emulsification index of 38.38%.

Pectins were extracted from whole PP using distilled water (DW) and different concentration levels of citric acid (CA) (0.5%, 1.0%, 1.5%, and 2%) with the aid of cellulase (C) enzyme. The characteristics of PPP were determined and compared to that of commercial citrus pectins (HS-R, HS-ES, and LC-S18). The PPP extract extracted with C1.5CA had the highest yield (24.63%), degree of esterification (50.20%), water-holding capacity (7.53 g water/g dry sample), oil-holding capacity (2.17 g oil/g dry sample), intrinsic viscosity, emulsifying activity (100%) and emulsion stability (100%). Good physicochemical properties of the C1.5CA-PPP extract can be associated with its notable <em>in vitro</em> bile acid-binding capacity and glucose-binding capacity. The findings indicate that the cellulase-assisted 1.5% citric acid (C1.5CA) extracted PPP has noteworthy physicochemical, hypocholesterolemic and hypoglycaemic properties.
