Well, some people just like it. Maybe you are wondering 'Why the heck are they doing?' but i do it 2 just cause it makes the apple more sweeter.
**But actually, the lemon juice prevents the apple from browning; this also works for other fruits like bananas and Pears.**
Because if you leave cut apple exposed to the air it starts to discolour by putting lemon juice vinegar mayonnaise or something acidy on it you stop this from occurring.
I think the lemon juice will preserve the apple, because lemon juice contains acids that act as a preservative preventing the natural aging process of an apple.
because it has alot of citrus in it
you can prevent an apple from browning by adding lemon juice to it
Lemon Juice (i tried)
If you put lemon juice (or any other citrus fruit juice) it will slow the browning process known as oxidisation.
Apple only brown due to oxidation, or the apple is being exposed to the air. To slow or even stop the browning of an apple, put it in an air-tight container, or seal all the air out.People have said that soaking the apple in lemon juice for about 5-10 minutes will help stop the browning of the apple, but it is just an old tale, but is worth a shot.
Coating freshly cut apples in sugar or syrup can reduce oxygen diffusion and thus slow the browning reaction. Lemon or pineapple juices, both of which naturally contain antioxidants, can be used to coat apple slices and slow enzymatic browning
Lemon juice helps slow down or prevent the oxidation of food, but I have heard little about preserving it. Peel an apple and dip it in acidulated water (water and lemon juice) and the apple won't turn brown (for a while).
It's a chemical change because the lemon and water cannot be separated by physical means. If it were a physical change, then the lemons and water would not be dissolved.
Normally in cooking cut apples are sprinkled with lemon or lime to slow oxidation (browning). Vinegar will also work depending on what you need the apples for.
Oxidation is cause by (obviously) the oxygen in the air. When you cut up fruit for instance, the parts without skin which are exposed will turn brown quickly. Squeezing lemon juice over your fruit (apple, pear, banana, ect) will stop oxidation because the juice contains Vitamin C (ascorbic acid). The ascorbic acid reacts with the oxygen preventing the browning on the apple (fruit). In theory, other citric fruits would do the same thing. Whenever making an apple pie (or pear whatever) squeeze a lemon over the pieces as you cut them up (and toss) this will stop the oxidation process while you are cutting up all the fruit.
well it doesn't really turn it brown it actually speeds up the proses of them turning brown even though vinegar is an acid it doesn't stop it from turning apples brown it speeds it up believe that it is a chemical in the apple and a chemical in the vinegar that interacts very bad.and the vinegars chemicals usually wins that's why vinegar speeds up the proses not slow it down
You can drink too much of anything. Even water. And most apple juice (unless it's cloudy) is really sugary.. so slow down.
Lemon juice works very well to slow the oxidation.
