This online reading from the Black Inventor Online Museum focuses on Lloyd Hall. This reading explores the life, education, and experiences of Lloyd Hall. Hall worked number of years exploring different areas of food chemistry. Upon joining Griffith Laboratories, Hall began looking into methods for preserving foods. Also, Hall maintained an interest in sterilizing foods, utensils, and tools. He eventually found a gas called ethylene oxide. The gas was introduced to foods within a vacuumed environment which eliminated the germs and bacteria while maintaining appearances, taste, and aroma. Hall's contributions to food preservation and sterilization revolutionized the way foods were processed, prepared, packed and transported, eliminating spoilage and health hazards, and improving efficiency and profitability for food suppliers. These contributions led to over 100 patents. Copyright 2005 International Technology Education Association
