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.
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.
An apple begins to brown when it is exposed to oxygen, which can occur at any temperature, but the process speeds up in warmer conditions. Typically, browning starts at temperatures above 32°F (0°C), as enzymes in the apple react with oxygen. To slow down browning, it's best to keep apples refrigerated and limit their exposure to air.
you can prevent an apple from browning by adding lemon juice to it
Yes, the browning of an apple core is a redox reaction. This process involves the oxidation of the compounds in the apple, such as polyphenols, which leads to the formation of brown pigments.
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 can affect the mass of an apple through processes like evaporation and respiration. Higher temperatures may lead to increased water loss through evaporation, potentially decreasing the apple's mass. Additionally, elevated temperatures can accelerate respiration rates in the fruit, leading to quicker degradation and loss of mass. Conversely, cooler temperatures can help preserve the apple's mass by slowing these processes.
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
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)
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.
