Abstract
This disclosure describes a low-density, biodegradable, open-cell structural biofoam generated through the gas-phase dispersion and mechanical fluid-shearing of an aqueous avian egg-white protein solution (specifically ovalbumin, conalbumin, and ovomucoid) stabilized by a high-fraction crystalline carbohydrate solute (sucrose). This document outlines the mechanical aeration, extrusion, and thermal desiccation techniques required to convert this viscoelastic liquid foam into a lightweight, rigid, porous solid block. The physical mechanics and foundational chemistry of this material are inherently enabled by historical cultural heritage, specifically the 1815 public documentation of Marie-Antoine Carême regarding mechanically aerated meringue structures and piping bag extrusion systems.
