Valorization of arabinoxylans from Linum usitatissimum (flaxseed) and galactomannans from Leucaena leucocephala (subabul) to develop hybrid hydrogels: Rheological, morphological and thermal characterization

Porous hydrogel composite with whey protein isolate and galactomannans of Leucaena leucocephala (subabul) seeds: Stability, rheological, thermal, and morphological characterization

“…The purified galactomannan so obtained is termed SG subsequently in the paper (Table A.2). SG was used for the optimization of SG1 hydrogel as per our earlier report (Ray et al., 2022) (Figure A.2) and as indicated in Section 2.4.…”

“…The SG1 and SGWP hydrogels were tested for their proximate composition and physicochemical and functional properties (Table 2) and correlated (Ray et al., 2022). The hydrogels showed marginal differences in their proximate composition.…”

“…Table 5 represents the texture profile analyses of the hydrogels. Figure A.4a,b indicates representative curves for texture profile analysis of the hydrogels and gel strength, respectively (Ray et al., 2022). The amount of polysaccharide as well as crosslinkers in the hydrogel influenced the texture of the gel.…”

“…The hydrogel from SG was prepared with 6.5% w/v SG + 1% w/v κC + 0.63% w/v KCl that was optimized in our earlier work (Ray et al., 2022), which has been concisely described in Section S2.2. These hydrogels are termed SG1 throughout the manuscript.…”

“…Hydrogels are three‐dimensional polymeric networks formed by the interaction between polysaccharides, proteins, or their combination. There are reports on the preparation of hydrogels from galactomannans (Ray et al., 2022), whey proteins (Platania et al., 2021), and also their combination (Aman mohammadi et al., 2019). Porous hydrogels are characterized by distribution of pores all along the hydrogel or composite matrix that can be either mesoporous (pore size 2–50 nm) or macroporous (pore size → 50 nm).…”
