Putting cut potatoes in water is a common practice that has been passed down through generations, but have you ever stopped to think about what it actually does? This simple technique has several benefits that can make a significant difference in the way your potatoes turn out, whether you’re boiling, roasting, or making fries. In this article, we’ll delve into the world of potatoes and explore the science behind this practice, as well as its effects on the cooking process.
Understanding the Science Behind Storing Cut Potatoes in Water
When you cut a potato, you’re exposing the inner cells to oxygen, which can lead to a series of chemical reactions that affect the potato’s color, texture, and flavor. One of the main concerns with cut potatoes is the formation of chlorogenic acid, a naturally occurring compound that reacts with oxygen to form melanin, the pigment responsible for browning. By storing cut potatoes in water, you’re creating an environment that slows down this reaction, helping to preserve the potato’s natural color and texture.
The Role of Water in Preventing Browning
The primary reason for putting cut potatoes in water is to prevent browning, which occurs when the enzyme polyphenol oxidase reacts with oxygen in the air. This enzyme is naturally present in potatoes and is responsible for catalyzing the reaction between chlorogenic acid and oxygen, leading to the formation of melanin. By submerging the cut potatoes in water, you’re effectively removing oxygen from the equation, thereby slowing down the browning reaction. This is especially important when you’re planning to use the potatoes in a dish where appearance is crucial, such as in a salad or as a garnish.
Effects ofTemperature and Water Quality
The temperature and quality of the water used to store cut potatoes can also have a significant impact on the outcome. Cold water is generally preferred, as it helps to slow down the browning reaction even further. However, using icy water can be beneficial in certain situations, such as when you’re trying to remove excess starch from the potatoes. On the other hand, using warm or hot water can actually accelerate the browning reaction, which may be desirable in certain cooking applications, such as making crispy potato fries.
Practical Applications of Storing Cut Potatoes in Water
Storing cut potatoes in water has several practical applications in the kitchen, from cooking and preparation to presentation and preservation. Here are a few examples of how this technique can be used to improve your cooking:
- Boiling and Steaming: Soaking cut potatoes in water before boiling or steaming can help to remove excess starch, resulting in a more tender and flavorful dish.
- Roasting: Storing cut potatoes in water can help to prevent browning and promote even cooking, making it ideal for roasting potatoes in the oven.
Additional Benefits of Storing Cut Potatoes in Water
In addition to preventing browning and promoting even cooking, storing cut potatoes in water can also have several other benefits. For example, it can help to:
Remove Excess Starch
Potatoes contain a significant amount of starch, which can make them sticky and difficult to work with. By storing cut potatoes in water, you can help to remove excess starch, making it easier to cook and prepare the potatoes.
Reduce Acrylamide Formation
Acrylamide is a potentially carcinogenic compound that forms when potatoes are cooked at high temperatures, such as when frying or roasting. Storing cut potatoes in water can help to reduce the formation of acrylamide, making it a healthier cooking option.

So next time you’re cooking with potatoes, be sure to give this technique a try and experience the difference for yourself.
What happens when you put cut potatoes in water?
When you put cut potatoes in water, several things happen. The most immediate effect is that the potatoes start to release starch and other compounds into the water. This is because the cutting process damages the cells of the potato, allowing the starches and other substances to escape. As the starches are released, they can make the water appear cloudy or murky. Additionally, the water can help to slow down the browning process that occurs when potatoes are cut, as it limits the amount of oxygen that can reach the damaged cells.
The release of starch and other compounds into the water can also have practical applications. For example, if you are planning to fry cut potatoes, soaking them in water can help to remove excess starch, resulting in a crisper exterior when they are cooked. Similarly, if you are trying to cook potatoes in a dish where you want them to retain their shape, soaking them in water can help to remove excess starch and prevent them from becoming too sticky or glue-like. Overall, putting cut potatoes in water can be a useful technique for preparing potatoes for a variety of different recipes.
Does putting cut potatoes in water help to prevent browning?
Yes, putting cut potatoes in water can help to prevent browning. When potatoes are cut, the cells are damaged, which causes an enzyme called polyphenol oxidase to be released. This enzyme reacts with the oxygen in the air to turn the phenolic compounds in the potato into brown pigments, resulting in the characteristic browning that occurs when potatoes are cut. By submerging the cut potatoes in water, you can limit the amount of oxygen that reaches the damaged cells, which in turn slows down the browning process.
The water helps to prevent browning in a few different ways. Firstly, it physically blocks oxygen from reaching the damaged cells, which slows down the reaction between the polyphenol oxidase enzyme and the oxygen. Secondly, the water can help to dilute the concentration of the phenolic compounds, which makes it more difficult for the browning reaction to occur. By preventing browning, putting cut potatoes in water can help to keep them looking fresh and appealing, which can be especially important if you are planning to serve them raw or use them in a dish where appearance is important.
How long can you keep cut potatoes in water?
The amount of time you can keep cut potatoes in water depends on a few different factors, such as the temperature of the water and the type of potato. Generally speaking, it is safe to keep cut potatoes in water for several hours, as long as the water is cold and the potatoes are kept refrigerated. If you are planning to store cut potatoes in water for an extended period, it is a good idea to change the water periodically to prevent the buildup of bacteria and other microorganisms.
It is generally not recommended to keep cut potatoes in water for more than 24 hours, as this can cause them to become waterlogged and lose their texture. Additionally, if the water is not changed regularly, there is a risk of bacterial growth, which can cause the potatoes to spoil. If you need to store cut potatoes for a longer period, it is usually better to store them in an airtight container in the refrigerator without water, or to freeze them. By storing cut potatoes properly, you can help to keep them fresh and safe to eat.
Can you use any type of water to store cut potatoes?
Not all types of water are suitable for storing cut potatoes. It is generally recommended to use cold, salt-free water, as warm or salty water can cause the potatoes to become waterlogged or develop off-flavors. Tap water is usually fine, but if you have particularly hard or soft water, you may want to use filtered or bottled water instead.
