i think chemical change
Yes, an apple slice that has been exposed to air can turn brown after a short period of time. If you need to keep the slices from turning, you can coat them with lemon juice or even lemon lime soda.
Carmel , brown
It is Black/Brown.
It is Black/Brown.
dark brown or black
It is because an apple have some iron so when it is exposed into air the iron gets oxidised and turns reddish/ brown.
Hypothesis 1: When you disturb the skin of an apple by cutting the apple into half, the exposed area will turn brown due to exposure to air.Hypothesis 2: If you snugly wrap or cover the exposed area of an apple after cutting it (disturbing the skin), you can slow down how fast the inside turns brown. Hypothesis 3: If you remove all of the skin of an apple and let it sit in the air, the outside will turn brown but the inside will not turn brown at the same rate. Hypothesis 4: If you remove all the skin of an apple AND slice the whole apple into pieces, all sides exposed to air will turn brown; if some slices are thicker, the inside will turn brown more slowly than the exposed outside areas.
leave it out exposed to the air, some apples dont brown, pick one that does brown easily
An apple should not be peeled because it will turn brown when the flesh is exposed to the air this can be prevented with citric acid (lemon juice)
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
I assume you are asking how to prevent a cut apple from oxidizing, or turning brown from contact with the air. Firstly, don't cut it before you need it...the longer it is exposed, the more chance for oxidization. Secondly, you can coat the exposed apple surfaces with lemon juice. Place the cut pieces in a Ziplock bag, add lemon juice, and shake gently to coat. The juice will inhibit oxidization. Thirdly, keep any cut apple pieces in an air-tight container to limit their exposure.
Dark brown apple seeds are brown
Not in general. It does protect the flesh of the apple from certain specific chemical changes (such as oxidation) to some extent, by keeping the oxygen away from the flesh. This is why an apple rapidly turns brown when you cut it: the previously protected flesh is now exposed to oxygen in the air.
Yes, chris brown was only reacting to her giving him an disease
That the lime was going to help the apple from turning brown.
When exposed to air, apples turn brown due to oxidation. Lemon juice is rich in vitamin C, which is a natural antioxidant, and stops the oxidation process that turns apples brown when exposed to air. It also lowers the pH (making it more acidic) which is hostile to some of the common microorganisms.
Light brown apple moth was created in 1863.
