Internal browning in Fuji apples is a physi- ological disorder which occurs during controlled atmosphere storage (CA) and therefore limits the use of CA for this cultivar. … We harvested fruit from a number of Fuji apple orchards at several harvest dates, some of which we stored at 2% O2 and 2% CO2 at 0°C.
What type of apple does not turn brown?

five to ten minutesDepending on the type of apple, it can turn brown almost instantly after being cut or take up to several hours.

Is it OK to eat apples that have turned brown?
The good news is that a brown apple is perfectly safe to eat. The bad news is that it’s ugly. … Pears, bananas, avocados, eggplants and potatoes can also undergo enzymatic browning, because they, like apples, contain phenols. Fun fact: Bruises in fruit are caused by the enzymatic browning too!
Why does a cut apple turn brown?
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
Will sliced apples turn brown in the fridge?
Your cut and sliced apples should be stored in resealable bags or airtight containers, and kept in the refrigerator for 3-5 days. Yes, sliced apples will begin to turn brown as soon as you slice them—but you can easily prevent the browning.
Which apples turn brown faster?
Some apples seem to brown faster than others While most plant tissues contain PPO, the level of PPO and the phenolic compounds, varies between varieties of fruits. This is why some varieties like Granny Smith brown less and les quickly than others, like Red Delicious.
Which fruit oxidizes the fastest?
Plums if left on the shelf, they will start to rot in 3-5days, if placed in the fridges 3-4 days. Pears on the shelf 3– 5 days, in the fridge 3-4 days. Grapes on the shelf 1 day, in the fridge 1 week. Apples on the shelf 1-2 days, in the fridge 3 weeks.

Why does salt water prevent apples from turning brown?
Salt solution is used as it reduces the amount of water on the surface of the apple through osmosis as the salt has a lower concentration of water, hence water in the apple would move out of the apple, thus slowing down oxidation. … The polyphenol oxidase in the lemon slows down the process of oxidation.
