Abstract
Disclosed herein is a method for preparing a low-cost fully-biodegradable plant fiber starch tableware. A plant cellulose material containing dregs of Scutellaria baicalensis is modified to obtain a modified plant fiber starch blank. Konjac gum is subjected to pulverization and ultrafine pulverization to obtain a colloidal binder combined with a deacetylated konjac gum. The colloidal binder is mixed with the modified plant fiber starch blank to obtain a mixture. The mixture is subjected to foam molding in a forming mold to obtain the low-cost fully-biodegradable plant fiber starch tableware.
