Limes are one of the most versatile and widely used citrus fruits, known for their acidic juice, aromatic zest, and numerous health benefits. Whether you’re a professional chef, a home cook, or a health enthusiast, limes are likely a staple in your kitchen. However, have you ever wondered how long limes last when they’re uncut? The shelf life of uncut limes is a common concern, as it affects the quality, safety, and usability of the fruit. In this article, we’ll delve into the world of limes, exploring the factors that influence their shelf life, storage methods, and tips for extending their freshness.
Introduction to Limes and Their Shelf Life
Limes are a type of citrus fruit that belongs to the Rutaceae family. They’re native to Southeast Asia and are now cultivated in many parts of the world, with Mexico, Brazil, and India being among the top producers. Limes are rich in vitamin C, flavonoids, and other essential nutrients, making them a popular ingredient in various cuisines, from beverages and desserts to savory dishes and marinades.
