This is because vitamin C is an antioxidant that reacts with the very reactive oxygen-centred radicals, turning them into less reactive species.
Hence, this reduces the amount of oxidative damage to the apple flesh.
This is why the apple in the vitamin C solution does not turn brown and remains fresh looking….
What does this discoloration of Apple mean?
Why do apples brown? … Secondary browning generally refers to discoloration that occurs when an apple is beginning to decompose due to fungi and bacteria. In other words, when the fruit is rotting. Primary browning in apples takes place when the fruit’s phenolic compounds react with oxygen.
What is the color of freshly cut apple in a glass of water?
brownas the control. This is due to the water restricting the amount of oxygen coming in contact with the fruit tissues. coloring on the surface of fruits). brown.
What is the color of freshly cut apple with vitamin C?
Answer. Answer: the apple in the vitamin C solution does not turn brown and remains fresh looking.
How do you stop Apple oxidation?
Stir two tablespoons of honey into one cup of water and soak your apple slices in the mixture for 30 seconds. This works because there is a compound in honey that stops the enzyme responsible for oxidation. Additionally, this is one of the methods that will not unpleasantly alter the apple’s taste.
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.
What happened to the Apple after 48 hours?
The apples after forty-eight hours, from left to right: The apple in water, the apple in water containing the vitamin C tablet, the apple in water containing the A-Z multivitamins and minerals tablet.
What is the color of the freshly Apple?
brownIn the case of apple, the freshness of the fruit is very critical to be maintained because when an apple is freshly cut and exposed to air, oxidation of the apple begins and the colour of the apple becomes brown. This phenomenon is called as enzymatic browning.
How do you measure an apple browning?
Measuring the degree of browning on an apple surface is difficult to do, but here is a paper that describes a method using spectrophotometer in reflectance mode measured at 400 nm. The authors actually did a scan over mutliple wavelengths, but 400 nm appears to quantitiate the brown color.
What is the color of Apple after it was left aside?
brownExplanation: Apple turned brown when it left aside.
What is the effect of putting vitamin C?
Here’s what happens when you apply vitamin C topically: It provides antioxidant protection. As with dietary vitamin C, applying the nutrient topically also feeds your skin protective antioxidants that fight free radical damage and inflammation caused by the sun, pollution and other factors.
Why do apples turn brown in the air?
Fruit turns brown when exposed to air because a reaction is happening when a cut piece of fruit is exposed to oxygen. … The chemical reaction can be simplified to: Polyphenol Oxidase + O2 → Melanin (Brown Color) Oxygen activates the compound polyphenol oxidase in the fruit to turn the fruit brown.
What is the color of an apple after 48 hours?
Answer. Explanation: Like when the flesh of the apple is exposed to oxygen,the color is turning to BROWN, and altering its color, flavor, scent, and in some cases, nutritional value.
Why Apple gets black after cutting?
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.
What liquid will keep apples from turning brown?
To use this method to prevent apples from turning brown, create a water bath for your apple slices with a ratio of 1 tablespoon of lemon juice to 1 cup of water. Soak the apple slices for 3 to 5 minutes, then drain and rinse them. This simple step should keep your apples from browning for several hours.

Which Apple will go brown the quickest Why?
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.
How long does an Apple take to 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. I think it usually takes five to ten minutes for an apple to turn brown. The oxidation process causes the apple to turn brown; oxygen present in the air reacts with the enzymes on the flesh of the apple.
Why do some apples not turn brown?

How do u stop apples going brown?
Here’s the short version: The best way to prevent browning is to soak the cut fruit in a saltwater solution (half a teaspoon of kosher salt per cup of water) for 10 minutes, then drain and store until ready to use. The mild salt flavor can be rinsed off with tap water before serving.
Why are apples that have been boiled after they are peeled do not change Colour to Brown?
When fresh fruits and vegetables are peeled or cut open, the enzyme called polyphenol oxidase (also called tyrosinase) contained in the cells is exposed to and reacts with the oxygen in the air. … When preparing fruits and vegetables for use, an anti-browning solution should be used to prevent them from turning brown.
