A resourceful woman has found a clever solution to prevent food spoilage using a simple ingredient – lemons. By poking a hole in the center of a lemon and extracting the juice, you can extend the shelf life of certain foods, such as sliced avocados. The citric acid in lemon juice acts as a natural preservative, slowing down the oxidation process that causes food to go bad. This simple hack has gained widespread attention on social media, with users praising it as a “life saver” and a “game-changer” for food storage.
