Why does watermelon juice separate into layers?

In addition to deterioration, the stratification of watermelon juice is generally divided into two normal situations: one is the stratification that settles at the bottom. Watermelon juice is a mixture of water and insoluble substances such as large molecular fruit particles. After standing for a period of time, the insoluble substances will settle down. Another is the stratification in which large molecular fruit particles float on the upper layer. There are some watermelon pulp particles in the upper layer, so the color is darker. In addition, when the juicer rotates at high speed, the pulp is broken and splashes in contact with the air, producing some foamy feelings, so it floats on the upper layer. The juice below is the juice, and the dark-colored fruit particles in it have floated to the upper layer, so it feels lighter. But the taste of the juice below is better.

Can you drink watermelon juice after it is layered?

It is normal for watermelon to separate into layers. We should not mistake it for spoilage. As long as it does not smell sour, it is still drinkable.

In summer, the nutrients in watermelon juice are easily oxidized and decomposed by oxygen, and many substances will precipitate after being left for a long time, making the color ugly, and the color, aroma and taste will deteriorate. This kind of stratified precipitation is not drinkable.

How long can watermelon juice be kept in the refrigerator?

Generally, it is best not to store squeezed juice for more than 24 hours, and it is best to consume it within 12 hours. Storing it in the refrigerator for too long may also cause it to deteriorate due to bacterial contamination.

Homemade watermelon juice is best drunk immediately after it is squeezed. Do not store it for too long. Even if it is placed in the refrigerator, its nutritional value will be affected! What's more, it has been placed in the refrigerator overnight! It is good if it is not spoiled. Do not drink it! It tastes bad and can easily upset your stomach! The stratification is the precipitation of watermelon fiber!
