METHOD FOR PREPARING A POWDER OF BROWN MICROALGAE BY BLENDING AND METHOD FOR PRODUCING RIGID OBJECTS FROM SAID POWDER.

摘要

The invention relates to a method for producing a rigid object from a powder produced from brown microalgae stirred under shear so as to extract proteins, such as actin, from said brown microalgae, said powder consisting of particles which have an equivalent diameter of less than or equal to 1.5 millimetres and which have a residual moisture content of less than or equal to 45%. According to the invention, such a method comprises a step of thermo­compression of said powder in a mould, said powder being brought to a temperature of between 50 and 100°C and subjected to a pressure of between 150 and 4000 bar for 50 seconds to 45 minutes. The invention also relates to the method for preparing said powder.
