Celebrating Women Food Scientists During Women’s History Month
It should come as no surprise that women have been shaping food science for centuries. From food-product packaging to animal handling to plant genetics, women have had a hand in many innovations that have helped make today’s food system vast, safe, and healthy. March is Women’s History Month, and this year we’re highlighting two spectacular women in food science—one who revolutionized frozen food safety and another who harnessed plant science to impact the health of millions. Dr. Mary Engle Pennington Sometimes referred to as the “Ice Woman,” Dr. Mary Engle Pennington played a pivotal role in refrigerated and frozen food safety in the early 20th century. Born in 1872, Dr. Pennington was refused a bachelor’s degree by the University of Pennsylvania in 1892 because of her gender. However, she persisted and received a certificate of proficiency in chemistry and then continued her studies to garner her doctorate in chemistry at the university in 1895. Following the passage of the 1906 Pure Food and Drugs Act, Dr. Pennington became the U.S. Food and Drug Administration’s (FDA) first woman lab chief, heading up the Bureau of Chemistry’s Food Research Lab. During her time at the FDA, Pennington revolutionized cold food storage, discovering that fresh foods that are consistently kept at a low temperature last longer than those that go through multiple temperature fluctuations. This finding was particularly important for the transportation of food products like cheese, milk, and eggs; if these foods were kept at a consistent temperature from starting location to their final destination, their bacteria levels stayed low and they were less likely to spoil. Pennington’s discovery led to the development of refrigerated transport as a means to maintain low temperatures over long distances, as well as an upgrade to home refrigeration, which began to use technology similar to that […]
