“…It is in accordance with the described Mw range (486 to 1,660 kDa) by Ding et al () from different polysaccharide fractions of flaxseed. However, the Mw of FSG in the current study is lower than the reported Mw of flaxseed mucilage 1.6 × 10 6 g/mol (1,600 kDa) to 10 × 10 6 g/mol (10,000 kDa) by Roulard et al () and 5.7 × 10 6 g/mol (5,700 kDa) reported for neutral polysaccharide of flaxseeds mucilage by Warrand et al (). The differences in Mw might be due to the different plant growing regions, varieties, extraction methods, purification approaches, and analytical procedures used for the assessment of Mw (Jia, Zhang, Lan, Yang, & Sun, ).…”

“…For instance, Hadad and Goli () found the chemical components of flaxseed mucilage as 11.2% ash, 5.5% moisture, 2.1% fat, 13.3% protein, and 67.7% carbohydrate content that is significantly higher than the values obtained in the current study, except the carbohydrate content. Moreover, Roulard et al () found 19.3% protein and 6% ash that is also higher than the values obtained in the current study. These remarkable differences pertained to seed variety, extraction temperature, water–seed ratio, pH, and method of mucilage extraction.…”

Flaxseed gum (FSG) is a heteropolysaccharide consist of neutral and acidic components that makes up approximately 8% of seed mass. FSG was extracted from mixture of brown and golden varieties of flaxseeds by hot water extraction method. The molecular weight distribution, monosaccharide analysis, chemical composition, and surface morphology of FSG were scrutinized in the current study to get a better insight regarding this important polysaccharide. The average molecular weight was recorded as 1,322 kDa with a polydispersity ratio of 1.6 for Mw/Mn and 2.4 for Mn/Mz. High‐performance liquid chromatography (HPLC) screening revealed that extracted FSG was comprised of rhamnose, arabinose, mannose, glucose, fucose, xylose, galactose, glucosamine, glucuronic acid, and galacturonic acid, of which mannose and glucosamine have not been reported previously. The antioxidant activities of FSG measured as DPPH, ABTS, reducing power, and total antioxidant activity clearly demonstrated the antioxidant potency of FSG. Fourier‐transform infrared spectroscopy (FTIR) and the Nuclear magnetic resonance (NMR) (1H, 13C) s pectra ratified the presence of functional groups typical for polysaccharide. Practical applications Flaxseed gum is a natural carbohydrate polymar. This study provides useful information regarding antioxidant potential, chemical, and structural characterization of FSG. The availability of a gum is fully characterized with bioactive composition, structural features, and antioxidant potential provides a toolset for the practical application in the food or drug industry.

Compared with bulk soil, rhizosphere has different properties because of the existence of root mucilage, which affects physical, chemical, and microbial processes. The slow response of rhizosphere to changes in water potential buffers water content changes and leads the rhizosphere to be wetter than bulk soil during drying. By affecting connectivity of the liquid and gas phases, mucilage can also influence solute transport and gas diffusion. Overview of the literature and previous models shows the lack of a model that describes the connectivity between different phases in the rhizosphere pore space during wetting and drying processes. A major challenge is that mucilage shows a complex behavior, which at low concentrations is more like a liquid, whereas at higher concentration, dry mucilage becomes a solid. In between, a viscoelastic state is observed where mucilage can be considered as a hydrogel. In this study a three‐dimensional pore‐scale model based on the lattice spring method is introduced and used to simulate drying of mucilage between two soil particles. The model is capable of reproducing spider‐web‐like structures that are specific for mucilage. This three‐dimensional mucilage drying model is qualitatively validated via environmental scanning electron microscopy (ESEM) images of dry mucilage between glass beads. The proposed model may provide us with a new perspective on hydrodynamic processes within the pore space of the rhizosphere. In addition, the model may help to better understand further important processes that strongly depend on rhizosphere hydraulic dynamics, such as solute transport, connectivity of the liquid phase, root penetration resistance, rhizosheath formation, and microbial activity.
