Examination of interfacial properties of quince seed extract on a sunflower oil-water interface

“…There is an apparent negative correlation between NaCl concentration and equilibrium ITs. The concentration range studied (0-0.5 M) is within the ''salting in" range for QSE, as shown by other researchers (Ashraf et al, 2017;Deng et al, 2019;Rezagholi et al, 2019), meaning an increase in NaCl concentration increases protein solubility. In the presence of Na + and Clions, protein chains are better solvated by water, which supports increased interactions between water molecules and the polymer.…”

“…These processes continue until monolayer coverage (Beverung et al, 1999). For QSE, during this phase, the initially adsorbed glycoproteins with smaller molecular weights are presumably replaced by the major QSE fraction, which is a very bulky and branched polymer of a xylose based backbone with galactose, glucose, galacturonic and glucuronic acid molecules and proteins attached to the branches (Hakala et al, 2014;Rezagholi et al, 2019;Wang et al, 2018). For polydisperse polymers, fractions with larger molecular weights adsorb preferentially over smaller ones.…”

The Renaissance of Plant Mucilage in Health Promotion and Industrial Applications: A Review

“…Quince seed mucilage is composed of cellulose and water-soluble polysaccharides, mainly partially O-acetylated (4-O-methyl-D-glucurono)-D-xylan [228]. It has a high molecular weight of 9.61 × 10 6 g/mol, which is higher than commercially available gums such as xanthan gum, guar gum, and gellan gum [229]. Rezagholi et al showed that QSM contains 85.04% carbohydrates, 13.16% uronic acid, 2.78% protein, 5.64% ash, 0.75% fat, and 5.77% moisture.…”

“…D-xylose accounts for 40.43% of the carbohydrates, D-mannose 31.11%, arabinose 6.39%, D-glucose 5.75%, and D-galactose 5.60%. Xylan and/or mannan forms the backbone, while arabinose, glucose and galactose are branches in the mucilage structure [229].…”

Stability enhancement of garlic essential oil using new opopanax gum/gelatin nanofibres

“…Wide range of polymeric materials is used as wall materials for the microencapsulation of bioactive compounds by electrospinning specially synthetic polymers, carbohydrates, proteins and their combination (Rezagholi et al, 2019).…”
