Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, an auxiliary water-dispersible organic polymer, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the auxiliary polymer to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and auxiliary polymer form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a particle packed, highly inorganically filled, cellular matrix are disclosed. Suitable inorganically filled mixtures are prepared by mixing together a starch-based binder, a solvent, inorganic aggregates, and optimal admixtures, e.g., fibers, mold-releasing agents, rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The inorganically filled mixtures have a predetermined viscosity and are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled cellular, structure matrix. The molded articles may be placed in a high humidity chamber to obtain the necessary flexibility for their intended use. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic materials. They have especial utility in the mass-production of containers, particularly food and beverage containers.

The invention discloses a preparation method of a high branching dextrin product and belongs to the field of deep processing, conversion and high value utilization of starch. The preparation method comprises the following main steps: carrying out heating, gelatinizing and declustering on starch milk, and then limiting hydrolysis by adopting alpha-amylase; treating by using glycogen branching enzyme; carrying out alcohol precipitation and drying to obtain the high branching dextrin product. The preparation method is characterized in that alpha-amylase incision declustering of starch and a biocatalytic transformation technology of the glycogen branching enzyme which is obtained by recombinant heterologous expression of actinomycetales Thermomonospora curvata are combined to synergistically act on the starch for transforming a long amylase substrate into a novel dextrin product with a high branch structure. According to the preparation method disclosed by the invention, preparation time of the high branching dextrin product is obviously shortened, and the yield of a product is greatly improved. The preparation method has the advantages of high branch, good solubility and the like.

A recombinant protein is prepared comprising a polypeptide of interest and a starch binding domain (SBD). The said SBD is obtainable from glucoamylase of fungi genus Rhizopus. The said recombinant protein comprising the said SBD can be purified by contacting with an affinity matrix such as starch, the SBD binds to the affinity matrix to isolate the recombinant protein. The recombinant protein can be purified by separating the association between the SBD and the affinity matrix by acid, alkaline, salt, or sugar. The polypeptide of interest may be an antibody, an antigen, a therapeutic compound, an enzyme, or a protein and may apply in pathogen destruction, vaccine producing, and oral care product manufacturing. The SBD further provides as a tool to screen or identify polysacchrides.
