Summary Flaxseed gum (FG) was prepared from six Canadian flaxseed (Linum usitatissimum L.) cultivars. Yield, neutral sugar content, acidic sugar content and protein content varied significantly among cultivar FG extracts. Zeta potential (−16.4 to −27.4 mV) and rheological properties of solution were cultivar dependent. Solutions prepared with CDC Glas FG had the highest viscosity (2.984 Pa•s), while CDC Sorrel produced the lowest (0.048 Pa•s). FG solutions exhibited pseudoplastic shear‐thinning behaviour. Viscosity of FG solution increased with concentration, while viscosity and pseudoplasticity decreased with increased temperature. NaCl addition decreased solution viscosity while adding sucrose increased viscosity. FG solutions prepared from Flanders and CDC Sorrel had the highest and lowest emulsion activity index, respectively, while solutions of CDC Arras and CDC Bethune FG had the lowest and highest emulsion stability, respectively. Findings presented here provide information that could enable greater utilisation in food, cosmetic and pharmaceutical industries as thickeners and/or emulsifiers.

“…In food formulations, WPI contributes versatile functional properties, enabling emulsification, gelation, and foaming (Turgeon & Beaulieu, 2001). Flaxseed gum (FG) constitutes about 8% of dry flaxseed mass and is recovered mainly as an extract of flaxseed hull that is released when whole or milled seed is soaked in water (Ziolkovska, 2012). Flaxseed gum solutions are separable to yield two distinct polysaccharide fractions: a neutral arabinoxylan of 1.2 × 10 6 Da which constitutes 75% of FG mass (Qian, Cui, Wu, & Goff, 2012); and an acidic rhamnogalacturonan‐I (RG‐I) polysaccharide (Qian, Cui, Nikiforuk, & Goff, 2012).…”

Whey protein isolate (WPI) was mixed with anionic flaxseed (Linum usitatissimum L.) gum (FG), and phase transition during coacervate formation was monitored. Effects of ionic strength and hydrogen bonding on coacervation of WPI‐FG system and corresponding rheological properties were investigated. During coacervate formation, structural transitions were confirmed by both turbidimetry and confocal laser scanning microscopy. Increasing ionic strength with sodium chloride (50 mM) decreased optical density (600 nm) at pHmax. Correspondingly, pHc and pHϕ1 decreased from pH 5.4 to 4.8 and from 5.0 to 4.6, respectively, while pHϕ2 increased from pH 1.8 to 2.4. Sodium chloride suppressed biopolymer electrostatic interactions and reduced coacervate formation. Adding urea (100 mM) shifted pHϕ1, pHmax, and pHϕ2 from 4.8, 3.8, and 1.8 to 5.0, 4.0, and 2.2, respectively, while pHc was unaffected. Optical density (600 nm) at pHmax (0.536) was lower than that of control in the absence of urea (0.617). This confirmed the role of hydrogen bonding during coacervate formation in the biopolymer system composed of WPI and FG. Dynamic shear behavior and viscoelasticity of collected coacervates were measured, and both shear‐thinning behavior and gel‐like properties were observed. Addition of sodium chloride and urea reduced ionic strength and hydrogen bonding, resulting in decreased WPI‐FG coacervate dynamic viscosity and viscoelasticity. The disturbed charge balance contributed to a loosely packed structure of coacervates which were less affected by altered hydrogen bonding. Findings obtained here will help to predict flaxseed gum behavior in protein‐based foods.

ABSTRACT:Objective: To formulate and evaluate the Levosalbutamol sulphate loaded microspheres of Chitosan and microspheres of Flax seed Mucilage in which both the polymers were checked as potential mucoadhesive agents and crosslinking was done with Glutaraldehyde for prolonging drug release for asthma therapy. Material and Method: Chitosan and Flax seed mucilage (by drying in Hot Air Oven) were used in appropriate concentration and crosslinked microspheres were prepared by Spray drying. They were evaluated for %Entrapment efficiency, Swelling behavior, %Mucoadhesion and Invitro drug release. The optimized batches were subjected to Particle-size distribution, Scanning-electron microscopy, Aerosolization behavior and Stability study. Result and Discussion: Microspheres having Chitosan polymer: Drug ratio of 2:1 and 0.6% of Glutaraldehyde and that of Flax seed Mucilage: Drug ratio of 3:1 and 0.9% of Glutaraldehyde had good mucoadhesion ability (89.50% and 85.11% respectively). Release rate was retarded up to 8 h and follows non-fickian diffusion. Particle-size distribution of optimized batches was represented by span index (3.822 and 2.953 respectively) and value was nearer to marketed product (1.975). Aerosolization behavior could be comparable with marketed product.
