Abstract
A method is provided for manufacturing a rigid object from a powder produced from shear stirred brown macroalgae so as to extract proteins, such as actin, from the brown macroalgae, the powder consisting of particles having an equivalent diameter smaller than or equal to 1.5 millimeters and having a residual moisture content smaller than or equal to 45%. The method includes thermo-compression of the powder in a mould, the powder being brought to a temperature between 50 and 100° C. and subjected to a pressure of between 150 and 4000 bars for 50 seconds to 45 minutes. Also provided is a method for preparing the powder.
Claims21
A method for preparing a powder of brown and/or red macroalgae, for the manufacture of rigid objects, wherein the method comprises the following steps in that order:
- harvesting said brown and/or red macroalgae;
- shear stirring said macroalgae in a tank a rate of at least 4 rpm, so as to extract proteins from said macroalgae, wherein said shear stirring is carried out at least partially under vacuum;
- drying said stirred macroalgae, so as to obtain stirred and dried macroalgae having a residual moisture content smaller than or equal to 45%;
- and
- grinding said stirred and dried macroalgae, so as to obtain a powder of macroalgae.
A method of manufacturing a rigid object at least partially from brown macroalgae, wherein the method comprises the following steps in that order:
- shear stirring said macroalgae in a tank a rate of at least 4 rpm, so as to extract proteins from said macroalgae, wherein said shear stirring is carried out at least partially under vacuum;
- drying said stirred macroalgae so as to obtain stirred and dried macroalgae having a residual moisture content smaller than or equal to 45%;
- grinding said stirred and dried macroalgae so as to obtain a powder of macroalgae;
- and
- thermo-compression of said powder in a mould, said powder being brought to a temperature between 50 and 100° C. and subjected to a pressure of between 150 and 4000 bars for 50 seconds to 45 minutes.
