1. A thermoplastic starch composition comprising,
(a) from about 40% to about 96% starch, by weight of the thermoplastic starch composition; (b) from about 1% to 40% plasticizer, by weight of the thermoplastic starch composition; and (c) from about 0.01% to about 5% reducing agent, by weight of the thermoplastic starch composition;
wherein said reducing agent has a redox potential of from about −50 mV to about −1200 mV; andsaid redox potential is measured in an aqueous solution at a temperature of about 80° C., wherein said aqueous solution comprises about 1% reducing agent, about 1% citric acid, and about 1% tribasic potassium citrate, by weight of the aqueous solution. |
