Abstract :
[en] tThe present study aimed to characterize and investigate the functional and angiotensin-I convertingenzyme (ACE) inhibition activities of chickpea water-soluble polysaccharides (CPWSP). Physico-chemicalcharacteristics were determined by nuclear magnetic resonance spectroscopy (NMR), Fourier transform-infrared spectroscopy (FT-IR) analysis, and X-ray diffractometry (XRD). Functional properties (waterholding capacity: WHC, water solubility index: WSI, swelling capacity: SC, oil holding capacity: OHC,foaming, and emulsion properties) and ACE activities were also investigated using well-established pro-cedures. The FT-IR spectra obtained for the CPWSP revealed two significant peaks, at about 3500 and500 cm−1, which corresponded to the carbohydrate region and were characteristic of polysaccharides.All spectra showed the presence of a broad absorption between 1500 and 670 cm−1, which could beattributed to C−H, C−O, and O−H bands in the polysaccharides. CPWSP had an XRD pattern that wastypical for a semi-crystalline polymer with a major crystalline reflection at 19.6◦C. They also displayedimportant techno-functional properties (SWC, WSI, WHC, and OHC) that can be modulated accordingto temperature. The CPWSP were also noted to display good anti-hypertensive activities. Overall, theresults indicate that CPWSP have attractive chemical, biological, and functional properties that makethem potential promising candidates for application as alternative additives in various food, cosmetic,and pharmaceutical preparations.
