Abstract

La présente invention concerne un procédé de formage d'articles solides biodégradables non comestibles à base de protéine granulaire, qui consiste à porter une formulation de protéine granulaire à une température maximale pouvant atteindre environ 80 DEG C de façon à créer un mélange sensiblement homogène et fluide capable d'être utilisé pour des articles biodégradables. Cette formulation contient environ 20 % à 85 % en poids de protéine granulaire, environ 5 % à 75 % en poids d'amidon, jusqu'à environ 14 % en poids d'eau, environ 10 % à 40 % en poids d'un plastifiant et au moins environ 0,01 % en poids d'un agent réducteur, le bisulfite de sodium par exemple, pour casser les liaisons bisulfure existant dans la protéine granulaire. On peut également employer des ingrédients facultatifs tels que des matières de charge, de la fibre, des lubrifiants ou des agents de démoulage et des colorants. Ces formulations se prêtent à la fabrication d'articles solides au moyen d'équipements de moulage par extrusion ou par injection.
