Other ways to keep apple slices fresh

While the saltwater method is one of the most effective ways to prevent apple slices from browning, there are alternative techniques for those who prefer to avoid salt. One classic approach is to soak apple slices in water mixed with a tablespoon of lemon juice. However, this method will only keep the apples fresh for a few hours before they start to brown. Other juices containing citric acid, such as lime or orange juice, can also serve as substitutes for lemon juice. Just keep in mind that this method may impart an unexpected citrus flavor to your apples.
Another interesting technique to prevent browning is to reassemble the apple after slicing and secure it with a rubber band. This method works because when the apple is cut, oxygen interacts with the polyphenol oxidase enzyme, leading to the formation of pigmented melanin. By tightly holding the apple slices together with a rubber band, you limit the oxygen exposure to the inside of the apple, thereby slowing down the browning process. With these tips, your lunchtime apple will be ready to enjoy!
