Abstract: A method for making an expandable half-product or pellet suitable for cooking by microwave oven (or other method such as frying) that results in a non-uniform, random design, while having a distinct pattern or style. The half product design is achieved by inducing stress cracks in the half product. The stress cracks are created by a controlled drying process whereby extruded half-products are first case hardened to create an outer skin that requires an internal build-up of pressure to penetrate. After creation of the outer skin, by drying in an oven or in ambient air, the half-product is heated to permit the vapor pressure of the moisture inside the half-product to break through the outer skin and escape. Such escape points induce stress cracks in random places in the half-product. The general pattern of the stress cracks can be varied by manipulation of the time-temperature profile of the case hardening and stress cracking steps.

Abstract: An improved method for maintaining a designed functional shape in fabricated, expanded snack products by utilizing discrete, solid lipid particles. These lipids must be solid at room temperature with a melting point above 100° F. such that they remain discrete and solid when mixed with the dough and are subsequently sheeted or extruded. During the toasting, frying, or baking step, the solid lipid particles melt and soften and disrupt the starch matrix, thus allowing steam to escape and preventing undesirable defects such as excessive blistering, pillowing, and other shape defects that prevent the intended functionality. The addition of solid lipid particles, however, prevents steam accumulation only in the localized area where a solid lipid particle exists. Thus, by changing the level of solid lipid particles in the dough, the degree of shape deformities can be controlled.
