Before U.S. women earned the right to vote in 1920, three female pioneers in food safety endured discrimination to make major contributions to the field. In the 19th century, Amanda Theodosia Jones (1835-1914) came up with the standard for vacuum canning. Effie Alberta Read, PhD, (1871 est.-1930) quietly spent two decades developing micro-chemical procedures to detect adulterated products, work that became crucial for enforcing the first comprehensive U.S. consumer protection law—the 1906 Food and Drugs Act. And later on, Mary Engle Pennington, PhD, (1872-1952) became the first female lab chief at the U.S. FDA, conducting research to make the food supply safer and fresher.
Jones had a penchant for science, but let spiritualism guide her decisions. In 1872, she reportedly received a message from the spirits to write to Professor LeRoy Cooley of Albany, N.Y., who she knew through her sister. The spirits further told her canning could be done in a better way by removing the air in the container. Though she had no prior experience with canning, she and Prof. Cooley were able to collaborate to create the “Jones Method,” also known as the “Pure Food Vacuum Preserving Process(es).” They created the first model in 1873 and were granted five patents to cover the process, two of which were issued to her alone. The method became the standard for canning in the U.S. Jones discovered their method added more flavor to the food, but didn’t remove any nutritional value. It killed bacteria by lack of oxygen instead of just heat.| | | Next → | Single Page
