Yes, acidy liquids stops any fruit in general from turning brown because the acid changes the natural pH level of the surroundings making it to where the protein melanin which is a pigment not to work properly to where it slows or completely stops it from turning brown

What is the effect of water on browning of apples?
Salt water slows the dehydration (browning of apples) because it is an acid.
How does pH affects the rate of browning?
The lower the pH, the more acidic a substance is. Citric acid is used to prevent apples from browning once they are cut. Therefore, an acid, low pH prevents browning. This is done by keeping oxygen from reacting with the apple with the barrier created by the citric acid.
Do apples contain citric acid?
Yes, apples do contain citric acid. They have about 10 percent citric acid that helps to prevent them from spoiling.
What liquids keep apples from browning?
Since you known that oxidation is responsible apple turning brown, you probably figured out that stopping oxidation would also stop the browning of apples. One way to prevent oxidation is to stop oxygen from reaching the PPO molecules in the cells. You block the oxygen by adding ascorbic acid (also known as vitamin C) to the apples to prevent the chemical reaction from taking place. Orange juice contains a lot of ascorbic acid. Placing an apple slice in contact with a orange slice or coating an apple slice in orange juice introduces ascorbic acid into the apple cells. Also, the orange juice and slice act as barriers to air, preventing oxygen from reaching the PPo molecules.
Why does citric acid prevent oxidation?
Most bacteria prefer a fairly limited pH range; using citric acid (or vinegar, or any other weak organic acid) lowers the pH and makes it difficult for bacteria to grow.
Is apples an acid or base?
ACID
Do different substances stop the browning of apples?
Lemon juice, because browning is caused by oxygen in the air. The citric acid is an anti-oxidant. Dipping apple slices in a solution of one or two tablespoons of lemon juice in a quart of water will usually prevent the slices from browning. (Metric : 15 to 30 ml per liter)
Are apples acidic?
Yes, apples are acidic. Apples have in them an organic acid called Malic Acid. This acid imparts acidity to apples.
What is the most effective way to prevent browning of fruit?

What causes browning when fresh fruits and vegetables are cut?
That ugly brown discolouration is called Oxidation. It can be prevented by immersing the vegetables in cold water, or by treating them with an acid, such as lemon juice. Potatoes should be placed in water. Fruits such as apples, peaches or bananas can be tossed with a little lemon to prevent browning. Better yet, get them into the pot as quickly as possible!
Does freezing apples prevent them from turning brown?
Only freezing apples will not keep them from browning. However, if you want to freeze them, there are a few ways of keeping them from browning while they sit in the freezer. You can dip apple slices in a solution of 1/2 teaspoon of ascorbic acid to 3 tablespoons of cold water, soak them in a solution of 2 tablespoons of salt and 1 gallon of water, or steam-blanch them for 1 1/2 minutes and cool them in ice water before freezing.
What acid is found in apples?
Malic Acid
