How do you slow the browning of an apple?
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.
Use lemon juice
Browning is polyphenol oxidase (PPO) react with oxygen which form "Rust" Coating freshly cut apples in sugar can reduce oxygen diffusion and thus slow the browning reaction.
Lemon Juice (i tried)
yes, but only if it is cut. it tastes good 2 :)
If you put lemon juice (or any other citrus fruit juice) it will slow the browning process known as oxidisation.
you can prevent an apple from browning by adding lemon juice to it
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.
If you keep the cut apple under water if will stop the oxygen in the air to react with the apple and no browning will occur.
You can always spray or brush it with lemon juice. I always to the cut apple into a lightly salt water right after cutting it. This will keep the cut apple from browning.
The vinegar will cause more browning on a red apple rather than a green apple because i did it for my science fair! and that was the results.
An apple called Arctic Apple has been genetically modified to be non-browning.
the urine in the lemon juice keeps the apple ripe
Enzymatic browning causes the browning in fruits, (turning pigments brown). As when you cut an apple, or drop and apple; damaging cells. Polyphenol oxidase(tyrosinase) is released by the damaged cells and it oxidizes naturally occurring phenols to guinones.
Brush it with orange juice.
Browning of the apples is caused by the oxidation of the enzyme phenol oxidase: phenol oxidase + oxygen---------------melanins
Lemon juice preserves the apple and keeps it from oxidizing. People use it on apple slices to prevent them from browning. It does not make them rot.
Because the reaction causing the browning, oxidisation (a result of exposure to oxygen), is slowed by the reduced temperature. However, a bit of water and lemon juice will slow it far more significantly.
If they are sitting out, not in a fridge, I would say about 30 minutes. If they are in the fridge, they have about double that time. To keep your apples from browning you can put lemon juice on them and this will delay the browning process.
Browning of apples is due to the creation of brown pigments through enzymatic polymerization of polyphenolic (normally colorless) apple compounds.
The rate of browning of apple will be fast in milk of magnesia. Monika Tandon (chemistry teacher) DPS Vasant Kunj
The acid in the juice prevents oxidation.
Spritz or soak the pieces with lemon juice.
The browning of the apple is due to the oxidation of the surface of the apple when it hits the air. When you've boiled the apple, the surface is now cooked so it no longer responds with oxidation.
Apple cider vinegar make a volcano erupt slow

Put the apple in a bag with a few drops of lemon juice in it.
The browning of apples is caused by a reaction between phenol and enzymes in the apple with oxygen from the air. The acid deactivates the enzyme so the browning reaction does not occur.
it usually takes about 1 hour or onwards to be brown
browning is due to oxygen, O2, reacting with chemicals released, breaking down the cells in the fruit. The reaction is called enzymatic oxidation as it is a process catalysed by the enzymes present in the apples
No it never dose because it depends what computer you have but this is a list that the computers it slows down slow down dell apple ( slow in the first place) non slow acer ( only)
i think you cut the apple into slices and soak them in lemon juice. it'll prevent them from browning.
Steve Jobs says that its very slow.
You can cut an apple in a lot of ways but you have to use a small knife and start from the top of the apple so you can cut out the core without mess up the apple. Then you slowly start cutting around the side of the apple very slow so you want cut into deep the apple.
Lemon juice is highly acidic so it will prevent the apple slices from browning for a few hours. Great for presentations or the picky eater you know.
The lower the pH, the more acidic a substance is. Citric acid is used to prevent apples from browning once they are cut. Therefore, an acid, low pH prevents browning. This is done by keeping oxygen from reacting with the apple with the barrier created by the citric acid.
Pot roast is a braised beef dish, made by browning a piece of beef and then slow-cooking it in liquid.
Water with a Vitamin C tablet dissolved in it works the best. Trust me, I did an experiment on it once.
You can bake an apple pie on the bottom rack of the oven. Many people do it this way to avoid over browning of the edges of the crust that can occur when using the centre rack.
Putting acids on a apple will not stop it turning brown as the apple is an acidic fruit itself so adding more acid would make it turn brown quicker.If you wanted to delay the browning of an apple you can always try neutrelising the apple by milk or something neutrel .It may no taste that great though .
There is a high amount of acid in lime juice and the part of the apple that makes it turn brown(enzyme) when exposed to oxygen, has an edible effect on the enzyme to protect it from browning
No No.... use lemon juice. Mix a little lemonjuice and water ( equal parts) dip cut side of apple in mixture and wrap in plastic wrap, put in the fridge.
Lemon juice, because browning is caused by oxygen in the air. The citric acid is an anti-oxidant. Dipping apple slices in a solution of one or two tablespoons of lemon juice in a quart of water will usually prevent the slices from browning. (Metric : 15 to 30 ml per liter)
If you are talking about apples browning after they are peeled and cut into pieces, then tossing them in a little olive oil right after cutting will prevent the browning. And olive oil is SO good. Any acidic liquid will prevent the browning. Lemon juice is often used. Lime, orange or grapefruit will work as well, and can add a nice flavor depending on what one is doing with the cut apples.
Yes it can, but the problem is that you wouldn't have the taste of apple anymore. You could use Lemon/Lime/Pineapple juice. Basically acidity helps but ruins the taste of the fruit itself. I just researched and found out that Ziploc bag is the most effective and cheapest way to keep it from browning by just sucking up the air when you seal bag. :D
Oxidation causes apples to turn brown. The browning you see is a result of the polyphenol oxidase (PPO) enzymes oxidizing.
Lemon juice works very well to slow the oxidation.
No they are slow and look dumb also really not my type of computer
Probably the most potent, easy and common preservative is that of lemon juice. Rotting or browning of apple flesh is a reaction that happens thanks to three chemicals: phenols, enzymes and oxygen. The phenols reside in one part of the apples' cells, while the enzymes reside in another. When an apple is cut or bruised, cells are broken open. The phenols and the enzymes then react with each other, with oxygen acting as a catalyst… Read More
The apple may catch some wind to slow it down. The bowling ball will hit the ground first. Now if this happened in a vaccuum...
You can drink too much of anything. Even water. And most apple juice (unless it's cloudy) is really sugary.. so slow down.
