Cucumbers get slimy due to their high moisture content and improper storage. It's best, therefore, to store cucumbers in the fridge's crisper drawer at 50°F to 54°F with 90%-95% humidity. To prevent them from getting slimy, shrink-wrap them or store them in a sealed plastic bag with paper towels, and keep them away from ethylene-emitting produce like tomatoes. If properly stored, cucumbers can last up to a week.
Cucumbers are a delightful addition to any meal, offering a refreshing crunch and a burst of hydration. However, their high moisture content also makes them prone to spoilage. If you've ever found slimy or mushy cucumbers in your fridge, you know the disappointment. But how can you keep your cucumbers fresh and prevent them from becoming a slimy mess?
Cucumbers often go soggy in the fridge due to their high moisture content. This makes them a hydrating food but also means they spoil faster. According to Amy Reed, a registered dietitian nutritionist and spokesperson for the Academy of Nutrition and Dietetics, "That high moisture content also predisposes them to a shorter shelf life." When cucumbers are exposed to too much moisture and improper storage conditions, they start to break down, becoming mushy and slimy.
You might be tempted to wash off the slime or cut away the mushy parts, but it's not a good idea. The slime is an indication that the cucumber is beginning to rot, and consuming spoiled produce can pose health risks. To avoid any potential health issues, it's best to discard any cucumbers that have become slimy or mushy. Compost them instead of eating them to ensure you're not ingesting harmful bacteria.
Proper storage is key to extending the freshness of cucumbers. Store them in the crisper drawer of your fridge, where the temperature is ideal—between 50°F to 54°F—and the humidity is high, around 90% to 95%. If the temperature drops too low for an extended period, cucumbers can suffer from chilling injury, leading to water-soaked areas, pits in the skin, discoloration, and decay.
To keep your cucumbers from getting slimy, consider shrink-wrapping them in plastic or storing them in a sealed plastic bag. Wrapping them in paper towels before placing them in the bag can also help, as paper towels absorb excess moisture, keeping the cucumbers fresher for longer. Additionally, avoid storing cucumbers near tomatoes, apples, avocados, or other produce that emits ethylene gas, as this can accelerate the spoilage process.
With proper storage, cucumbers can last up to a week in the fridge. However, keeping an eye on their condition is essential. If they start to show signs of spoilage, it's best to use them quickly or compost them.
