The present invention is directed toward a process for making solid biodegradable articles from wheat gluten. Hydrated wheat gluten is provided in the form of a cohesive, elastic dough. The cohesive, elastic dough comprises at least 8% by weight wheat gluten and wherein the wheat gluten comprises a protein having a primary structure. The cohesive, elastic dough is formed into a shaped article and placed in an environment sufficient to remove excess water from the shaped article without modifying the primary structure of the wheat gluten protein, such that a solid biodegradable article results. The solid biodegradable articles of the present invention comprise at least 8% by weight wheat gluten.
L'invention concerne un procédé permettant de produire des articles solides biodégradable à partir de gluten de blé. Ce procédé consiste à préparer du gluten de blé hydraté sous forme d'une pâte élastique cohésive, laquelle contient au moins 8 % en poids de gluten de blé, le gluten de blé comprenant une protéine présentant une structure primaire. Cette pâte élastique cohésive est formée en un article moulé, lequel est ensuite placé dans un environnement permettant d'éliminer l'excès d'eau de l'article moulé sans modifier la structure primaire de la protéine de gluten de blé, de manière à produire un article solide biodégradable. Les articles solides biodégradables décrits comprennent au moins 8 % en poids de gluten de blé.
