Potatoes are a staple food in many households, and it’s not uncommon for people to buy them in bulk. However, when it comes to storing uncooked peeled potatoes, many of us are left wondering how long they can be kept in the fridge. In this article, we’ll delve into the world of potato storage and explore the factors that affect the shelf life of uncooked peeled potatoes in the fridge.
Understanding the Basics of Potato Storage
Before we dive into the specifics of storing uncooked peeled potatoes, it’s essential to understand the basics of potato storage. Potatoes are a type of root vegetable that belongs to the Solanum tuberosum species. They are composed of about 80% water, which makes them prone to spoilage. When potatoes are exposed to light, heat, or moisture, they can undergo a series of chemical reactions that affect their texture, flavor, and nutritional value.
The Importance of Storing Potatoes in a Cool, Dark Place
Potatoes should be stored in a cool, dark place to slow down the process of spoilage. The ideal storage temperature for potatoes is between 40°F and 50°F (4°C and 10°C). This temperature range helps to slow down the breakdown of starches into sugars, which can make potatoes sweet and unpalatable. Light can also trigger the production of chlorophyll in potatoes, which can give them a greenish tint and make them toxic.
