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.

The invention discloses a preparation method of a highly branched dextrin product, which belongs to the field of high value utilization of starch deep processing transformation. The main steps are as follows: after heating the starch milk to gelatinize and decluster, use α-amylase to restrict hydrolysis, then treat with glycogen branching enzyme, and obtain a highly branched dextrin product through alcohol precipitation and drying. The present invention preliminarily utilizes α-amylase to decompose clustered starch, and combines the biocatalytic conversion technology of recombinant heterologously expressed glycogen branching enzyme of Actinomycetes Thermomonas genus Thermomonospora curvata to synergistically act on starch to convert long amylose The substrate is converted into a novel dextrin product with a highly branched structure. The invention significantly shortens the preparation time of highly branched dextrin products, greatly improves the product yield, and has the advantages of high branching, good solubility and the like.

The invention provides a high temperature resistant modified starch and its preparation method and application. The invention converts the crystalline region of the base starch into an amorphous region through the gelatinization process, so that the -OH at the C6 position of the starch structural unit is exposed to the solution environment In the process, the concentration of ‑OH that can participate in the reaction is increased, the grafting rate between the base starch and the grafting agent is increased, and then the temperature resistance is improved; and the initiator and modifier solution are added alternately to prolong the activity of the starch free radical Long time, increase the grafting rate of the reaction monomer, and then improve the temperature resistance effect of the modified starch; also use N, N-methylenebisacrylamide and tripropylene glycol dienyl ester as cross-linking agents, combined with starch, Form a three-dimensional network structure to improve the temperature resistance effect. The results of the examples show that the high temperature resistant modified starch provided by the present invention is suitable for both fresh water slurry and salt water slurry, and it can still maintain a high fluid loss after high temperature treatment at 150°C, and has excellent temperature resistance.
