Why do fruits and vegetables turn brown?

Answer 1

all cells contain thousands of enzymes. These enzymes do all of the work necessary for the cell to live its life., the actual mechanism that causes browning in apples and potatoes involves an enzyme called polyphenol oxidase, also known as tyrosinase.the browning reaction results from the oxidation of phenolic compounds in the fruit under the action of an enzyme called polyphenol oxidase (PPO), which is common in plant tissues

Answer 2

When apples are bitten into of cut and left out, why do the brown? Apples brown because of the oxogen in the air mixing with polyphenol oxidase, the enzymes. When this happens the apple oxogenizes and turns brown. The reason they turn brown is because the oxogen, the enzymes, and the iron in the apple and in the air mix and it damages the cells

Answer 3

when the fruit goes brown it is because of the fruity oxidation.

Answer 4

The question is why fruit go brown why not green , blue or red , the brown colour is for ferric oxide so iron present in fruits becomes oxidized by reacting with atmospheric oxygen.

Answer 5

fruits turn brown shortly after they are cut because the bactiera has eaten away at the fruit.

Answer 6

They start to oxidize, they start to react with oxygen in the air.

Answer 7
