The Use of Electric Circuit and Sound Signal in Determining the Albumen Height of Eggs

Abstract

Albumen height has been reported as an objective measure of egg quality by Heiman and Carver (1936) and Wilgus and Van Wagenen (1935). Indirectly, albumen height is used to determine egg grades and has been adapted by Haugh (1937) for scoring the interior quality of eggs which is used as the basis for many quality control programs.The height of the albumen is measured in millimeters using a tripod micrometer with direct reading dial as shown in Figure 1. This type of instrument has been used for a considerable length of time, therefore has become standardized by the egg industry. In the process, the egg is broken on a flat surface, the tripod is placed over it, and the measuring rod is adjusted downward until the rod touches the albumen. The critical point occurs just as it touches, but it is difficult to observe this juncture quickly. With several hundred…
