ABSTRACT:
To form a binder from naturally occurring products without extraction or purification steps, the binder utilizes proteins from the germ or endosperm of cereal grasses or from the seed of buckwheat, oil seed plants, Amaranthus or leguminous plants or from leaves. The protein has a thermoplastic microstructure with linear polymers of molecular weight of at least 2000 linked with peptide linkages of at least 50 in number. The naturally occurring product is ground or milled without further processing and thus includes carbohydrates, particularly as cellulose, and possibly fats, yeast or materials yielding ash upon burning, with the carbohydrates being at least 5% of the proteins by weight. The binder may include some initiators or catalysts to polymerize fats or other initiators or catalysts to polymerize proteins. Structures formed using the binder may be made from naturally occurring agricultural products with the protein already in them, or in the alternative, the binder may be mixed with filler material and water from other sources.
