Highlights
  • Onion makes for the most popular ingredient used in Indian cuisine
  • Onions contain dozens of medicinal chemical compound
  • Bacteria contaminate onions once exposed
Onion makes for the most popular ingredient used in Indian cuisine; it is one of the major parts of the content used in curries, salads and other savouries. Onions not only help add a distinct flavour, but also give the curries a certain consistency. Moreover, onions are long known for their health benefits. According to the book 'Healing Foods' by DK Publishing, "Onions contain dozens of medicinal chemical compounds that have antibacterial and anti-inflammatory action in the body and promote good heart and gut health."

Considering all the positives that onion has, what could possibly go wrong? It is believed that peeled onions shouldn't be stored or refrigerated.



According to Health Practitioner and Macrobiotic Health Coach Shilpa Arora, "Bacteria contaminate onions once exposed and if they are left as it is, they may get oxidized further leading to a host of health problems. It is advised to cut them only when you want to cook them." Nutritionist and Dietitian Parmeet Kaur agrees, "When you cut onions, the cell walls are disrupted; water and fluids are released, which may contain nutrients that promote bacteria growth. If you refrigerate peeled onions, the cold and humid temperature may make them soggy and lead to decay due to the combined process of bacteria growth and decay."

Cut onions immediately go bad as they attract the bacteria around the surroundings they are stored in, no matter whether they are stored in the refrigerator or in an open kitchen space. For example, if you slice your onion or even peel it on a cutting board that you also used to cut raw chicken, any bacteria from the chicken juice will be easily transferred to the peeled onion.



How to ensure peeled onions are stored safely?



According to National Onion Association, never store peeled onions in plastic bags as the lack of air movement will reduce their storage life. The best way to store peeled onions is to wrap each onion in a paper towel and place them in refrigerator to keep them cool and dry. According to the United States Department of Agriculture (USDA), chopped or sliced onions can be stored in a sealed container in your refrigerator at the proper temperature of 40 degree Fahrenheit or 4.4 degree Celsius.
