Four extraction methods of hot-water (HWE), ultrasound-assisted (UAE), microwave-assisted (MAE), and ultrasound-microwave assisted (UMAE) were utilized to determine the best technique to extract pectin from the common fig (Ficus carica L.) skin. UMAE (11.71%) significantly showed a more extraction yield than MAE (9.26%), UAE (8.74%), and HWE (6.05%). A significant dose-dependent antioxidant capacity for pectins 1,1-diphenyl-2-picryl-hydrazyl (DPPH), and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonicacid) (ABTS) radical scavenging activity was found. The UMAE-pectin with the maximum galacturonic acid content (76.85%) and mol. weight (6.91 × 103 kDa) presented the highest emulsifying activity (61.2-61.3%) and emulsion stability (94.3-95.2%) with a monomodal droplet size distribution at cold and ambient storage temperatures A non-Newtonian shear-thinning behavior was detected at 1.5-3.0% pectic-solutions X-ray diffraction (XRD) anal. showed a non-crystalline nature for pectins extracted by UMAE. FTIR spectroscopy and HPLC photodiode array detector revealed that conventional and novel extraction technologies do not change the chem. structure and monosaccharide composition of pectin significantly.
International Journal of Biological Macromolecules published new progress about Emulsion stability. 59-23-4 belongs to class alcohols-buliding-blocks, name is (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, and the molecular formula is C6H12O6, Formula: C6H12O6.
