Let’s learn what to do if the apple juice changes color below.

In the hot summer, it is a happy thing to have a glass of refreshing and delicious freshly squeezed juice, but experienced housewives will find that the apple juice changes color, and the brightly colored juice becomes gray and black, which looks unappetizing. Does the “life” of freshly squeezed juice only last for a few minutes? Let me teach you a trick to delay the discoloration of freshly squeezed juice - add some lemon juice to it. Don't believe it?

Step 1: Squeeze out two 10 ml cups of lemon juice and put them in small cups respectively. Step 2: Chop the apples and peaches into small pieces at the same time. Step 3: Put the chopped fruits into a juicer with 100 ml of water and squeeze them into juice. Step 4: Pour the squeezed apple juice and peach juice into the cup with lemon juice and the cup without lemon juice respectively. The amount of juice in the four cups should remain basically the same.

Next, it’s time to wait quietly for changes. Let’s take a look at the difference between apple juice and peach juice with and without lemon juice added after 1 minute.

One minute later, the juice with lemon juice still maintains its attractive color, while the juice without lemon juice has become dull in color and tends to turn black and oxidize. When we left the four cups of juice for 5 minutes, the contrast became more obvious. The apple juice without lemon juice had a cloudy bottom and a grayish-black color, while the apple juice with lemon juice retained its original color.

To enhance the contrast effect, we made a cup of peach juice without adding anything 20 minutes ago, and compared the peach juice with the peach juice with lemon juice. Please see the comparison picture below:

Why can a little bit of lemon juice prevent freshly squeezed juice from changing color? We all know that lemons are rich in vitamin C. The reducing vitamin C can delay the oxidation time of the juice when exposed to air. At the same time, the citric acid in lemons can inhibit the activity of phenol oxides in the fruit, which is the culprit that makes the juice turn black. It seems that lemon juice is really a good tool to prevent freshly squeezed juice from changing color.

We found that no matter how expensive the juicer is, the apple juice squeezed out will change color. Apple juice discoloration is also a common phenomenon. We must drink more fresh fruit juice in our daily life. It is also relatively simple to make. If there is a baby at home who does not like to eat fruit, we can squeeze some juice for the baby.
