What is oxidation in food?
Oxidation is a chemical process produced by air exposure (oxygen), heat or light in which food transforms their physical properties by others due to a chemical reaction and, therefore, its color, its taste, its flavor, its flavor, is modified Its smell, its texture, etc … antioxidants are substances that prevent oxidation and are very useful to keep food in perfect condition, maintaining not only their physical but also nutritional properties such as vitamins and some amino acids that are destroyed or They volatilize with ease as soon as they come into contact with oxygen. Many foods already contain antioxidants naturally present in their composition but many times it is necessary to add some externally to be able to keep them for longer. These can be natural (citrus, vinegar, salt, etc …), chemicals (E300 or ascorbic acid, E330 or citric acid, etc …) or materials such as hermetic bags or film paper.
Tricks to prevent the apple from oxidizing
These are some of the most effective ways to prevent apples from oxidizing and changing their physical properties easily and quickly:
Lemon
Lemon and acids in general are perfect to get the cut apple not to oxide and also help to keep it for a maximum of 12 hours under cooling. You can choose to add a couple of drops on the piece of cut apple and this will slow down its oxidation. On the other hand, if what you want is to keep it for up to a week, take the following steps:- Pour the half-lemon juice in 1 liter of water.
– Enter the apple cut into pieces and let it rest for 5 minutes.
– Remove the pieces of apple and rinse them with the help of warm water.
– Guard them in a container or hermetic bag inside the fridge for a maximum of 5-7 days.
This is the typical trick that occurs in the steps of many kitchen preparations that carry this fruit as in this apple cake recipe with peach jam.
Elastic leagues or rubber banditas
This is a perfect option to take fruit to school or your work and thus avoid the problem of loading with instruments to cut and keep the peeled apples:- Cut the apple into 9 pieces equal and keep it together
– Place a bandita or league by binding these pieces horizontally.
– Then you can save it in a hermetic bag or container and take it peacefully where you need with the confidence that the fruit will not be brown (oxidized), watery or with a bad taste.
