Why Store Potatoes in Water?
Storing potatoes in water is a common practice, especially when you need to keep them for a short period. Water helps to keep the potatoes fresh by preventing them from coming into contact with oxygen, which can cause them to turn brown or develop off-flavors. Additionally, water helps to keep the potatoes cool, which slows down the growth of bacteria and other microorganisms that can cause spoilage.
The Science Behind Storing Potatoes in Water
When potatoes are cut or peeled, the cells are damaged, and the starches are converted into sugars. This process is called enzymatic browning, and it can cause the potatoes to turn brown or develop off-flavors. Water helps to slow down this process by preventing the potatoes from coming into contact with oxygen. Additionally, water helps to keep the potatoes cool, which slows down the growth of bacteria and other microorganisms that can cause spoilage.
The Role of Oxygen in Potato Spoilage
Oxygen plays a significant role in potato spoilage. When potatoes are exposed to oxygen, the starches are converted into sugars, and the cells are damaged, leading to enzymatic browning. Additionally, oxygen can cause the growth of bacteria and other microorganisms that can cause spoilage. By storing potatoes in water, you can prevent them from coming into contact with oxygen, which helps to slow down the spoilage process.

How long can I keep potatoes in water before cooking?
You can keep potatoes in water for several hours or overnight before cooking. However, it’s essential to change the water periodically to prevent bacterial growth. If you’re planning to keep them for an extended period, make sure to store them in the refrigerator to slow down bacterial growth.
It’s also crucial to note that the type of potato and its maturity can affect how long it can be stored in water. New potatoes, for example, have a thinner skin and are more prone to spoilage than mature potatoes. If you notice any signs of spoilage, such as sliminess or mold, it’s best to discard the potatoes immediately.
What happens if I keep potatoes in water for too long?
If you keep potatoes in water for too long, they can become waterlogged and develop off-flavors. The starches in the potatoes can also break down, making them unappetizing and potentially causing digestive issues. Furthermore, if the water is not changed regularly, bacteria can multiply, leading to foodborne illnesses.
In extreme cases, potatoes can even start to sprout or develop roots if they’re submerged in water for too long. This can make them inedible and even toxic. To avoid these issues, it’s best to cook potatoes within a few hours of soaking them in water or store them in a cool, dry place.
Can I keep potatoes in cold water to slow down spoilage?
Yes, keeping potatoes in cold water can help slow down spoilage. Cold water slows down the growth of bacteria and other microorganisms that can cause potatoes to spoil. However, it’s essential to change the water periodically to prevent the buildup of bacteria and other contaminants.
If you’re planning to store potatoes in cold water for an extended period, make sure to keep them refrigerated at a temperature below 40°F (4°C). You can also add a tablespoon of lemon juice or vinegar to the water to help prevent bacterial growth.
How do I store potatoes in water before cooking?
To store potatoes in water before cooking, start by filling a large container or pot with cold water. Add the potatoes and make sure they’re fully submerged.
