Technical Abstract: Microcellular starch foams have been reported with pore sizes ranging from the micron to the nanometer range. These foams can sorb volatile compounds but can also absorb more than seven times their weight in solvent. Microcellular starch foam was used as a reservoir material to study the controlled release of various solvents. The foams were used to meter the release system of 2-heptanone over a forty day period to control parasitic mites in bee hives. Another important use of starch is in the manufacture of fully compostable, environmentally sound food service containers using a baking process. Containers made primarily of starch are not moisture resistant and must be laminated. A process was developed to both bake the product and laminate the product in a single step. The laminated samples were moisture resistant and had functional properties similar to those of commercial packaging products.
