Antioxidant and Antibacterial Activities of a Purified Polysaccharide Extracted from Ceratonia siliqua L. and Its Involvement in the Enhancement Performance of Whipped Cream

The main objective discussed in this research was to determine the structural characteristics of carob kibble water-soluble polysaccharide (KWSP), extracted from Ceratonia siliqua L., and assess its vitro antioxidant activities, as well effect on whipped cream. results obtained through 13C, 1H, hetero-nuclear single quantum coherence (HSQC) nuclear magnetic resonance (NMR) Fourier transform infrared spectroscopy (FT-IR) analysis indicated that KWSP had characteristic bands polysaccharides. Thin layer chromatography (TLC) high performance liquid (HPLC) suggested is a hetero-polysaccharide composed glucose fructose, with an average molecular weight (Mw) amounting 65 KDa. In addition, showed good water holding capacity (WHC), oil (OHC), emulsification stability, rated 3.14 ± 0.05 g/g, 0.87 0.02 71 0.01%, respectively. activity investigated vitro, demonstrating important DPPH ABTS⋅+ radical scavenging activities total capacity. exhibited antibacterial against Listeria monocytogenes, Staphylococcus aureus, Salmonella enterica. On other hand, incorporation cream investigated, enhance consequently extend expiration date. Moreover, reduces formation conjugated dienes trienes fat.
