Patent ID: 8153176

Claim:
A method to obtain a biodegradable protein based thermosetting composition, consisting in an homogenous mixture of an essentially dry protein or protein based powder, an essentially anhydrous and liquid alcohol and optionally one or more ingredients, characterized in that it comprises the following steps: a. premixing the alcohol with all those anhydrous ingredients other than protein which are soluble therein to obtain an homogenous essentially anhydrous fluid fraction, under controlled conditions of moisture and temperature, maintaining the mix temperature below the setting temperature of the thermoset composition; and b. premixing the dry protein powder under the same conditions of step a) with all those anhydrous ingredients other than the proteins which are not soluble in the fluid fraction obtained in step a) to obtain a dry fraction; and c. mixing up, under the same conditions of step a) the fluid and dry fractions obtained respectively in steps a) and b) until a homogenous, plastic and shelf-cohesive mass is obtained.
