Student’s research reduces food waste by improving use-by dates

She returned to Purdue in 2017 to join the Process Modeling and Validation lab of Dharmendra Mishra, assistant professor of food science. Muniandy completed another master’s degree in food science with a food processing emphasis. Two years later, she began her doctoral program under Mishra’s guidance.

Muniandy’s research has helped develop innovative technology to help predict the shelf life of food and beverages. The custom equipment built for her study aims to reduce analysis time.

“Every food has an expiration date printed on the label,” Muniandy explained. “The way to decide those labels comes with a methodology that is universal across most foods. It takes months to complete.”

Muniandy noted “use-by” and “freeze-by” dates can confuse consumers, especially with their built-in cushions.

“My research is focused on shortening the analysis time so we can test products faster in efforts to increase accuracy.”

Because retail outlets cannot sell products beyond their expiration date, Muniandy’s research could lead to a reduction of waste at retail and consumer levels.

“I envision myself to be a leader in the food industry,” said Muniandy. “I want to prepare for that while I’m still in school.”

Muniandy has held leadership roles in the Purdue Student Government and served as president of the Hoosier Chapter of Phi Tau Sigma, the honor society for food science and technology. She also led Purdue teams in national product development contests including three top-three finishes in the American Society of Baking’s annual competition.
