Rheological properties of Salecan as a new source of thickening agent

Polysaccharides modification through green technology: Role of ultrasonication towards improving physicochemical properties of (1-3)(1-6)-α-d-glucans

“…A similar pseudoplastic behavior was observed in the case of the glucans produced by Leuconostoc dextranicum NRRL B-1146 (Majumder & Goyal, 2009) and Agrobacterium sp. ZX09 (Xiu, Zhou, Zhu, Wang, & Zhang, 2011). As for sonicated glucan, the Newtonian plateaus for these solutions were observed at the high shear rates (1e100 1/s).…”

“…Gum arabic showed a flat curve with essentially Newtonian, especially similar in the viscosity to UMG4. According to Xiu et al (2011), the macromolecule in solution might exhibit considerable stiffness, making the chains more easily oriented under shear. Thus, the shear thinning property of tested glucan solution was the outcome of an orientation effect under shear.…”

A novel thermo-responsive hydrogel based on salecan and poly(N-isopropylacrylamide): Synthesis and characterization

“…The peak at 893 cm −1 is the character absorption bands of ␤-configuration in d-glucopyranose. The weak absorption bands at 814 cm −1 could be attributed to a little ␣-glucopyranose in salecan [36].…”

“…The introduction of salecan chains led to a higher tan ı than pure PN gel. Generally, the ratio of dissipated energy could be represented by tan ı and the higher tan ı means more dissipated energy [36]. These factors accounted for the higher fracture strain of salecan/PNIPAm semi-IPNs.…”

“…The structure of salecan is a linear (1→3)-␤-d-glucan consisted of ␤-1-3-linked glucopyranosyls with a small quantity of ␣-1-3-linked [33]. As a novel polysaccharide, salecan has been utilized in the fields of both food and medical in our laboratory [34][35][36][37][38]. With a high density of hydroxyl groups, the large molecular weighted (2 × 10 6 Da) salecan could be further modified for multifarious applications.…”
