Chopping onions is an inevitable task for many home cooks and professional chefs alike. However, the process of chopping onions can be a daunting one, especially for those who are sensitive to the irritating effects of onion fumes. The release of syn-propanethial-S-oxide, a sulfur compound found in onions, reacts with the water in our eyes to form sulfuric acid, which is the primary cause of tear production when chopping onions. But fear not, as there are several techniques and tools that can help minimize the discomfort and make the process of chopping onions a tear-free experience.
Understanding the Science behind Onion-Induced Tears
To effectively address the issue of crying while chopping onions, it’s essential to understand the science behind it. Onions contain a gas called syn-propanethial-S-oxide, which is released into the air when the cells of the onion are damaged, such as when chopping or slicing. This gas reacts with the water in our eyes to form sulfuric acid, which irritates the eyes and triggers the release of tears. The amount of gas released and the intensity of the irritation can vary depending on the type of onion, with some varieties being more potent than others.
The Role of Enzymes in Onion-Induced Tears
The enzyme alliinase plays a crucial role in the production of syn-propanethial-S-oxide. When an onion is chopped or damaged, the alliinase enzyme is released, breaking down the amino acid sulfoxides into syn-propanethial-S-oxide. The amount of alliinase enzyme present in the onion can affect the amount of syn-propanethial-S-oxide produced, and subsequently, the intensity of the irritation.
Factors that Influence Tear Production
Several factors can influence the amount of tears produced when chopping onions, including:
The type and variety of onion being used
The method of chopping or slicing the onion
The amount of damage caused to the onion cells
The individual’s sensitivity to onion fumes
The presence of other irritants in the environment
Techniques for Chopping Onions without Tears
While it’s impossible to completely eliminate the production of syn-propanethial-S-oxide, there are several techniques that can help minimize the amount of irritation caused by onion fumes. Some of the most effective techniques include:
Using a very sharp knife to minimize cell damage
Chopping the onion under cold running water to dilute the syn-propanethial-S-oxide
Cutting the onion from the root end to the top, rather than across the onion
Using a fan to blow the onion fumes away from the face
Chilling the onion in the refrigerator for about 30 minutes before chopping
The Benefits of Using a Sharp Knife
Using a very sharp knife is one of the most effective ways to minimize the amount of syn-propanethial-S-oxide produced when chopping onions. A sharp knife causes less damage to the onion cells, resulting in less gas being released into the air. Additionally, a sharp knife makes the chopping process faster and more efficient, reducing the amount of time spent in close proximity to the onion fumes.
Chopping Under Cold Running Water
Chopping the onion under cold running water is another effective technique for minimizing tear production. The water helps to dilute the syn-propanethial-S-oxide, reducing the amount of gas that reaches the eyes. Additionally, the cold temperature of the water can help to slow down the release of the alliinase enzyme, resulting in less syn-propanethial-S-oxide being produced.

What causes onions to make us cry?
Onions contain a gas called syn-propanethial-S-oxide, which is released into the air when the cells of the onion are damaged, such as when it is cut or chopped. This gas reacts with the water in our eyes to form sulfuric acid, which irritates the eyes and causes them to water. The amount of gas released can vary depending on the type of onion, with some onions producing more gas than others. Additionally, the way an onion is cut can also affect the amount of gas released, with finer cuts releasing more gas than larger cuts.
The reason why some people seem to be more affected by onion fumes than others is not entirely clear, but it may be due to individual differences in tear composition or the anatomy of the eye. Some people may also be more sensitive to the irritant effects of the gas, which can be exacerbated by factors such as dry eyes or allergies. Understanding the cause of onion-induced tears can help us develop strategies to minimize or prevent them, such as using a very sharp knife to minimize cell damage, cutting the onion under cold running water, or using protective goggles to shield the eyes from the gas.
