Ultrasonication as a highly efficient method of flaxseed mucilage extraction

Ultrasound assisted extraction decreases the intrinsic viscosity of the mucilage from 12.5 dL/g (for magnetic stirring) to 6.2 dL/g, and the weight-average molecular weight of the largest polysaccharides from 1.5 × 106 Da to 0.5 × 106 Da, whilst having a limited impact on protein content and monosaccharide composition.
