Question

when we cut apple why it becomes brown after some time...
​

Answer 1

Explanation:

Corn fabric is a fairly new concept in the world of eco-friendly textile. The fabric conceptualises the idea of using fermented plant sugars derived from corn. The initial production stage involves making plant sugar from maize. The next step is to ferment the sugar, which is similar to making simple yogurt. The residue obtained after sugar fermentation is then converted into polylactide, which is a high-performance polymer. The fibre used for fabric production is extracted from polylactide.

On the flip side, the fermentation process goes through a chemical transformation, thus it is not cent percent natural, but, the transformation is considered renewable, as it bars the use of any fossil resources like oil etc. Another pitfall with corn fabric is that traditionally grown corn leaves exceptionally large eco-unfriendly footprint via pesticides, water use, and land hogging. However, the use of energy is almost half as it does to make cotton or even organic cotton.

This unappetizing phenomenon is actually due to a chain of biochemical reactions known as “enzymatic browning". When an apple is injured (or cut into pieces), the plant tissue is exposed to oxygen. This triggers an enzyme known as polyphenol oxidase (PPO) to—wait for it—oxidize polyphenols in the apple’s flesh. This results in new chemicals (o-quinones), which then react with amino acids to produce brown-colored melanins. Different apple varieties contain different amounts of both the initial enzyme and the polyphenols, and thus they brown at different rates.
