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.
in 75-100
Lemon Juice (i tried)
High temperature makes the volume greater.
yes it does!!!
yes
cause I say so
Browning of apples is due to the creation of brown pigments through enzymatic polymerization of polyphenolic (normally colorless) apple compounds.
you can prevent an apple from browning by adding lemon juice to it
An apple called Arctic Apple has been genetically modified to be non-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.
Temperature does affect enzymatic function - temperature affects the "active site" of the enzyme and so the substrate cannot bind to it anymore (process is called denaturation)
chemical reaction.
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.
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.
It depends on many factors. First, how populated the area is. Second, the temperature. Third, the animals in the area. There is no specific answer.
An apple has always the temperature of the surrounding air. There is no special temperature in an apple.
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.
