Onions are an important part of Indian cuisine, but sometimes black spots or mold appear on onions during storage. People often ignore it and use it by cutting it. But is it right? Let’s explore the reasons behind it and its health implications.
Why do dark spots occur?
Black spots on onions are usually caused by a fungus called Aspergillus niger. This fungus spreads rapidly in moist and warm environments. Improper storage of onions for a long time further aggravates this problem.
Is it edible?
Onions with black spots are completely unsafe to eat. Onions affected by the fungus can produce toxic compounds called mycotoxins, which are harmful to the body.
Damage to health

Allergies and respiratory problems
Mold particles can enter the body through inhalation, which can aggravate allergies, coughs and asthma. -
Effects on the liver and kidneys
Mycotoxins can accumulate in the body for long periods of time and can damage the liver and kidneys. -

This infection can be serious in case of diabetes, cancer or low immunity.
What should be done if black spots are seen on the onion?
-
Discard such onions immediately.
-
Even if the spots are mild, do not use onions as the fungus can spread further inside.
-
