Abstract: A welding method and shielding gas therefor which enables the use of gas metal arc welding to produce smooth welds with little or no surface oxidation and without encountering arc instability during the metal deposition.

Abstract: A food shell with improved distribution quality, eating texture and resistance to breakage or fracture is provided. A food shell is formed from a cereal grain, for example, wheat or corn, and is processed to form a blistered texture during a cook step. During cooking, the shell develops a controlled delaminated texture and is cooked adequately to make an integral shell in the desired shape. After cooking a softening agent is added to the shell to soften it for delivery to consumer without breakage. By controlling the delaminated structure, the degree of cooking and the final plasticizer content, the cooked shell, if cooked further, will produce a light, crisp and tender shell.

Abstract: An improved tortilla is provided which has increased shelf life while maintaining improved flexibility over the shelf life. The tortilla is comprised of flour, water and other plasticizing agents to provide a low moisture content product still having a high liquid content. The tortilla is cooked to completely gelatinize the starch in the interior of the tortilla. The tortilla is cooled, packaged and stored having about a ninety (90) day shelf life while maintaining sufficient flexibility to prevent appreciable cracking when folded for use.
