After carefully choosing the freshest produce at the market, people face even more choices with vegetables, fruit, meat and dairy products at home that can help prolong freshness, minimize waste and prevent foodborne illnesses.
There are several methods to store and preserve food, such as canning and pickling produce, freezing leftover ingredients, and storing food in the refrigerator. Although refrigeration is effective and most households have the appliance, experts say it is safe to say most families simply set it and forget it.
“Storing perishable items in refrigerated conditions is the first step, but it is necessary to stay aware of how long certain foods have been prepared, exposed to the air, and stored. Refrigerated items are still able to develop mold and dangerous microorganisms like listeria, Salmonella, and E. coli, so consumers must stay alert and take necessary precautions,” said Emily Hilliard, press secretary for the U.S. Department of Health and Human Services.
This is especially important during the holiday season, when people buy more and expect meals to last. Planning recipes, buying less and being creative with extras and leftovers can help reduce food waste, said Diane Beckles, professor at the University of California, Davis, who studies the quality of fruits and vegetables. She said these steps can also help stretch shopper’s budgets, especially with inflation on the rise and federal food aid under threat as the government shutdown continues.
Experts say proper food storage starts before groceries even reach a refrigerator. Buy products before their expiration or “sell by” dates — which tell stores how long to display their products, and are not safety dates. Follow handling instructions and place foods in the refrigerator within two hours of being at room temperature. Other tips include keeping appliances clean by wiping spills, especially from thawing meat, and discarding spoiled food. The Department of Energy recommends keeping refrigerator temperatures between 35-38 degrees Fahrenheit (1.7-3.3 degrees Celsius).
Social media offers seemingly endless tips to make food last longer, such as cleaning fruits before refrigerating and storing everything in plastic or glass containers. But experts say there isn’t just one right way to properly store many foods.
It comes down to understanding temperature and relative humidity when storing produce, said Wyatt Brown, emeritus professor at California Polytechnic State University in San Luis Obispo. After that, “it becomes more refined” and includes considerations like storage space, timing of meals and personal preference.
