Abstract

Procedure for molding by injection articles formed from native starch and water. Comprises: a) plastify a composition of native water and starch at a temperature between 80j and 240ºC; b) molding by injection to the composition of water and plasticized native starch, at a temperature between 80j and 240ºC, at a pressure between 6 107 and 3 108 n/m2, and within a refrigerated mold and c) expelling the solid product from the mold. The native water/starch composition, contains: starch which is chosen between maize, fig or potato starch; water in a 5 to a 30 in weight; diluents that are chosen between sunflower proteins, gelatine soy proteins and others; plasticizants that are chosen between polyenethenglicol, glycerin and other; lubricants that are chosen between fatty, vegetable and lipid acids and coloring agents.
