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.
Yes, you can prevent an apple from turning brown by exposing it to an acidic solution like lemon juice or vinegar, which will slow down the oxidation process that causes browning. Another method is to store the cut apple in an airtight container or plastic wrap to reduce its exposure to oxygen.
Both saltwater and lemon juice can slow down the rate of dehydration in apples. Saltwater creates a hypertonic solution that reduces water loss from the apple cells, while the acidity in lemon juice can help preserve the apple by inhibiting enzymatic browning and dehydration.
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).
Yes, immersing cut fruit in a water solution, such as lemon juice or saltwater, can help prevent browning due to oxidation. The acidic nature of these solutions helps slow down the enzymatic browning process.
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
