Avocados are known to brown quickly after being cut, making it frustrating to have leftover half. This article outlines the best ways to keep a halved avocado fresh, highlighting the effectiveness of citrus juice and onion slices.
Avocados are a tasty addition to any breakfast, but there's nothing more frustrating than buying one only to find the inside has turned brown and rotten after a few days. A common hack circulating on social media suggests storing sliced avocados in water to keep the unused half fresh, but not only is this method ineffective, it also poses a health risk that could leave you feeling unwell.
Submerging avocados in water creates a damp environment that fosters the growth of bacteria like salmonella. Even if the water appears clean, it will be contaminated, as any bacteria on the avocado skin will multiply rapidly. Fortunately, the experts at Appetise have revealed that the best way to keep half an avocado fresh is to simply coat the flesh with citrus juice, reports the Express. They said: 'We've all been there you only needed half an avocado, and now you're left with the other half. But fear not! You can prevent it from turning brown and keep it fresh for later use. 'Start by drizzling the exposed flesh with some lemon or lime juice. The natural acidity acts as a shield against browning.' When you cut an avocado and expose its flesh to air, an enzyme is triggered, causing it to spoil and turn brown. Lemon juice has a low pH, which disrupts the activity of the enzyme. The juice also forms a protective barrier over the flesh to prevent it from spoiling prematurely. To extend the life of a halved avocado, simply drizzle it with lemon juice, wrap it snuggly in cling film, and place it in an airtight container to minimise air exposure. Doing so can keep your avocado fresh for several more days, making sure your breakfast remains both tantalising and waste-free. For those lacking lemon juice and aiming for a savoury twist, storing an avocado with an onion slice is another clever trick. An expert said: 'The sulphur compounds contained in the onion help slow down oxidation, preventing browning.
