Bioplastic compositions containing between 2 wt. % and 25 wt. % of at least one starch, between 40 wt. % and 65 wt. % of at least one plasticizer, and between 1 wt. % to 10 wt. % of at least one acid are used as insulation materials. A method of making a bioplastic composition includes the steps of heating a first aqueous mixture containing at least one plasticizer and at least one acid; adding at least one starch to the first aqueous mixture to produce a second aqueous mixture; heating and mixing the second aqueous mixture to produce a precipitate; and separating the precipitate from residual liquid of the second aqueous mixture to produce a bioplastic composition.

Described herein are starch-based materials, and formulations including such for use in directional alignment extrusion processes. The present compositions exhibit critical shear stress characteristics that allow extrusion at high shear rates and line speeds, without onset of melt flow instability. The present compositions provide sufficient melt strength to allow such compositions to be directionally oriented by stretching the heated polymer (e.g., the polymer melt) following initial extrusion, directionally aligning the molecular chains of the heated polymer blend in the machine-direction, the cross-direction, or both. In an embodiment, the starch-based material is blended with one or more thermoplastic materials having desired melt flow index value(s), which serves as a diluent, allowing the very viscous starch-based component to be processed under such conditions. The starch-based materials (and masterbatches thereof) may exhibit high molecular weight, high shear sensitivity, strain hardening behavior, and/or a very high critical shear stress (e.g., at least 125 kPa).

An example starch-based material for forming a biodegradable component includes a mixture of a starch and an expansion additive. The starch has an amylose content of less than about 70% by weight. The expansion additive enhances the expansion and physical properties of the starch. A method of preparing a starch-based material is also disclosed and an alternate starch-based material for forming a biodegradable component is also disclosed.

Formation of low-crystallinity phytosterol nanoparticles via cooling-controlled supercritical carbon dioxide (SC—CO.sub.2) impregnation of phytosterols into biodegradable nanoporous starch aerogels and methods of preparing these aerogels are disclosed. The nanoporous starch aerogels increase water dissolution and bioaccessibility of the phytosterols, thereby making them available for preparation of high nutraceutical value foods.
