Powder compositions of egg shell and methods for producing compositions in powder of eggshell

摘要

Abstract invention patent: "compositions in powder, egg shell and methods for producing compositions in powder of eggshell. The present invention relates to a process for the manufacture of powdered egg shell for use in the production of biobased products.The process involves the exposure of a quantity of egg shell at high speed from the air at ambient temperatures to spray out of the egg and separate the component of the egg shell of the component of the inner membrane.Thus, the process avoids the use of high temperatures and other aggressive chemical treatments to remove the inner membrane of the egg shell, resulting in a material of egg shell that keeps the original structure of lipid - protein, egg shell which is native. The powder.Consequently, it is provided with a composition of eggshell powder which is substantially free of material of the inner membrane and lipid - protein has a structure substantially similar to that of the egg shell from which the powder is derived. Also is provided a composition of composite polymer comprising a component of the shell of an egg and a polymer component.
