Characteristics of Edible Jelly Enriched with Faba Bean (Vicia faba L.) Pod polysaccharide and Investigation of Its Prebiotic and ACE-Inhibitory Potential

This study investigated Faba Bean Pod Polysaccharide (FBPP) extracted using ultrasound-assisted methods (۶۵°C, ۵۰ min, ۵۰% amplitude), achieving an extraction yield of ۱۵.۵۸%. The purified FBPP exhibited a zeta potential of -۲۷.۱۳ mV and an average particle size of ۴۲۰.۱ nm. Functional characterization revealed water- and oil-holding capacities of ۲.۹۸ g/g and ۳.۴۱ g/g, respectively. FBPP demonstrated significant biological activity, showing ACE (Angiotensin-Converting Enzyme) inhibitory effects (IC۵۰ = ۰.۲۲۳ mg/mL) and promoting the growth of Lactobacillus casei. When incorporated into jelly formulations, FBPP maintained favorable physicochemical properties (pH ۲.۸۸, acidity ۴.۰۱) while achieving high sensory acceptance scores. These findings position FBPP as a promising natural ingredient for functional foods, combining prebiotic potential with antihypertensive properties through ACE inhibition.
