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.
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
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.

Will an apple turn color if vinegar is applied?
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.
Is browning of cut apples a physical or chemical chnage?
The browning of cut apples is a chemical change. This occurs when the enzymes in the apple (specifically polyphenol oxidase) react with oxygen in the air, resulting in the formation of brown pigments called melanin. This process alters the apple's chemical composition, which is characteristic of a chemical change rather than a physical one.
Apples used to turn brown when you cut them But don't anymore Why not?
Apples turn brown when cut due to a reaction between enzymes and oxygen, known as enzymatic browning. However, many modern apple varieties have been genetically modified or selectively bred to reduce this enzymatic activity, resulting in slower browning. Additionally, some apples are treated with ascorbic acid (vitamin C) or other antioxidants to prevent browning. This innovation helps maintain their visual appeal and freshness for longer periods.
How do I stop apples from freezing?
To prevent apples from freezing, store them in a cool, dry place rather than in the freezer. If you have cut apples, you can coat them in lemon juice or salt water to reduce browning and keep them fresh. Additionally, keeping them in a tightly sealed container in the refrigerator can help maintain their texture and flavor, preventing them from freezing. Avoid exposing apples to extreme cold temperatures, such as leaving them outside in winter weather.
What turns apples brown?
Apples and some other fruits undergo a process called enzymatic browning when cut and allowed access to the air. The process is a bit complicated using the enzyme polyphenoloxidase which results in the brown pigmentation.
Why do apples turn brown?
Fruits such as apples and pears will rot if exposed to certain fungi. These fungi are relatively weak but can attack damaged or overly ripened fruit. When fruits such as apples ripen, they give off a gas called ethylene. Ethylene gas accelerates the ripening process, which will lead to over ripening. The easiest way to prevent browning is to put the sliced apples in water. You can also squeeze like lemon juice on and helps it keep from browning. Most of the time apples brown when cut them. Apples can turn brown even when they are not cut though, but it takes considerably longer to brown. Basically because the apple contains Iron. The iron inside the apple rusts when it comes in contact with air and that's why it turns to that brownish color.
Will temperature affect the browning of an apple?
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.
