Since you known that oxidation is responsible apple turning brown, you probably figured out that stopping oxidation would also stop the browning of apples. One way to prevent oxidation is to stop oxygen from reaching the PPO molecules in the cells. You block the oxygen by adding ascorbic acid (also known as vitamin C) to the apples to prevent the chemical reaction from taking place. Orange juice contains a lot of ascorbic acid. Placing an apple slice in contact with a orange slice or coating an apple slice in orange juice introduces ascorbic acid into the apple cells. Also, the Orange Juice and slice act as barriers to air, preventing oxygen from reaching the PPo molecules.

∙ 9y agoMilk does stop apples from browning. You will have to soak the apples in the milk for several minutes. You can also use lemon to stop fruit from browning.

∙ 10y agoyes it can actually! i did a science project and if you soak the apple slice in milk for ten minutes it prevents it from turning brown for about 7 hours. hope this helps :)

Can you slice apples and soak them to keep them from browning since you won't be making the dessert for a couple of hours?
A small amount of lemon juice dashed over cut apples will keep them from browning.
Why does sugar keep cut apples from browning?
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.
What is the effect of water on browning of apples?
Salt water slows the dehydration (browning of apples) because it is an acid.
Why does salt prevent apples from browning?
As salt absorbs moisture from the surrounding air, it prevents apples from browning.
What is the average browning point of apple slices?
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.
How sugar affect the browning of apples?
Browning of apples is due to the creation of brown pigments through enzymatic polymerization of polyphenolic (normally colorless) apple compounds.
How does fruit fresh on apples help it from browning?
No because no
Do liquids with acid in them prevent browning of apples?
Yes, acidy liquids stops any fruit in general from turning brown because the acid changes the natural pH level of the surroundings making it to where the protein melanin which is a pigment not to work properly to where it slows or completely stops it from turning brown
I have noticed lately that apples aren't going brown when cut and left out are they adding something to apples now to prevent them browning?
Certain varieties of apples have more of a tendency than others to turn brown when cut. Some agriculturists have worked on select breeding for a less-browning characteristic. Also, storage apples will brown quicker than fresh apples. Right now, you should be getting fresh apples in the stores.If you are referring to purchased cut apples, there are preparations - like lemon juice and sulfites - that will reduce browning.
What are the products and reactants in an browning apple?
Browning of the apples is caused by the oxidation of the enzyme phenol oxidase:phenol oxidase + oxygen---------------melanins
Can sugar prevent apples from browning?
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
Does lemon extract keep apples from turning in an apple pie?
Lemon juice is acidic and helps prevent your apples from browning. You can achieve the same thing using lime juice as well as it's not so much about adding flavour as it is about maintaining a nice colour
