Abstract
A method of extracting polysaccharides from alfalfa plants, the method comprising the followings steps: milling of the alfalfa plants; addition of a buffer solution to the milled alfalfa plants and separation of the milled plants, thus producing a polysaccharides-composed supernatant and a protein-composed pellet; and precipitation of the polysaccharides in the polysaccharides-composed supernatant; the alfalfa plants comprising alfalfa seeds; and the method comprising the following steps, prior to the milling step: soaking of the alfalfa plants in water so as to swell the alfalfa seeds; mesh filtration of the alfalfa plants comprising the swollen alfalfa seeds; and drying of the alfalfa plants comprising the swollen alfalfa seeds.

A method of extracting polysaccharides from alfalfa plants, said method comprising the followings steps:
- milling of the alfalfa plants;
- extracting polysaccharides by addition of a buffer solution to the milled alfalfa plants;
- separating the milled alfalfa plants of the buffer solution, thus producing a polysaccharides-composed supernatant and a protein-composed pellet;
- and
- precipitating the polysaccharides in the polysaccharides-composed supernatant so as to produce a polysaccharide gum pellet;
- wherein the alfalfa plants comprise alfalfa seeds;
- and
- wherein the method further comprises the following steps, prior to the milling step:
- soaking of the alfalfa plants in water so as to swell the alfalfa seeds;
- mesh filtrating the alfalfa plants comprising the swollen alfalfa seeds;
- and
- drying of the alfalfa plants comprising the swollen alfalfa seeds, so as to concentrate galactomannan in the polysaccharide gum pellet.
