Locust bean gum provides excellent mechanical and release attributes to soy protein-based natural hydrogels

Effect of pH and biopolymer ratio on phase behavior, rheology, and structural characteristics of pea protein isolate‐locust bean gum coacervates

“…The LBG spectra showed strong and broad OH group‐related peaks appearing at 3340 cm −1 (OH stretching), at 2921 cm −1 (CH stretching), at 1639 cm −1 (COO − stretching) as well as at 1016 cm −1 (COH stretching). These results aligned with other studies 30,39 …”

“…The LBG stock solution showed negatively charged polyelectrolyte behavior ranging from −25.8 to −0.5 with decreasing pH from 7 to 3. This could be due to chemical reactions between anionic groups like hydroxyl (OH) and carboxyl groups (COO − ) present in the LBG stock solution 30 . These results aligned with Haddarah, Bassal 25 who also identified the zeta potential values ranging from −2.67 to −12.95.…”

“…This could be due to chemical reactions between anionic groups like hydroxyl ( OH) and carboxyl groups (COO À ) present in the LBG stock solution. 30 These results aligned with Haddarah, Bassal 25 who also identified the zeta potential values ranging from À2.67 to À12.95. Also, there was no significant difference in zeta potential values after pH > 6 of LBG stock solution as shown in Figure 2.…”

“…These results aligned with other studies. 30,39 The PPI-LBG complex spectra formed at pH 4.5 and PPI:LBG ratio of 5:1 was comparable with individual biopolymers (PPI and LBG) as shown in Figure 6. However, there was a shift in different functional groups including COO À from 1639 to 1625 cm À1 and NH 3 + group in terms of Amide I (1630 to 1625 cm À1 ), Amide II (1520 to 1512 cm À1 ), and Amide III (1386 to 1389 cm À1 ).…”

“…21 LBG belongs to a family of galactomannan containing a structure of (1-4)-b-D-mannopyranosyl backbone with an attachment of (1-6)-a-D-galactose single units. 22 LBG exhibits many salient features, such as high hydrophilicity, excellent biocompatibility, good acid/alkali resistance and high strength. 23,24 Simultaneously, the abundant surface functional groups of LBG make it possible to combine with other materials for synthesizing new materials with excellent performance.…”
