Abstract

A method for extracting xyloglucan contained in the primary walls of plant cells, and more particularly of dicotyledonous plants, includes mixing primary walls of plant cells with a first aqueous solution and to which a strong base is added, which leads to the formation of a first liquid residue and a first solid product, this first solid product comprising mainly holocellulose. The first product is mixed with a second solution, the second solution comprising the strong base, which leads to the separation of the cellulose and xyloglucan contained in the first product. The method uses a relatively limited number of steps and uses chemical compounds with low human and environmental toxicity.

Dependent claims

A method for extracting xyloglucan contained in the primary walls of plant cells of a dicotyledonous plant, the method comprising carrying out the following steps:

a) a first step including mixing primary walls of plant cells, whether native or extracted, with a first aqueous solution and to which a strong base is added at a concentration of between 0.1 mol/L and 0.75 mol/L, the execution of the first step leading to the formation of a first liquid residue and a first solid product, the first solid product comprising mainly holocellulose;
and
b) a second step of mixing the first product with a second solution, the second solution comprising the strong base at a concentration of between 1 mol/L and 3 mol/L, the second step leading to the separation of the cellulose and xyloglucan contained in the first product.
