How to tell if juice is spoiled Tips for identifying spoiled juice

Juice is a favorite of many people. It is a liquid substance squeezed from a variety of fruits. It tastes sweet and sour and is very nutritious. However, the shelf life of juice is relatively short and it often goes bad. Some people don’t know much about how to identify spoiled juice and don’t know how to identify whether the juice has gone bad. Today, the editor will introduce to you several tips for identifying spoiled juice. You will learn it after reading this.

1. Look at the texture

The most common fruit juice in our life is transparent drink without pulp. After this kind of juice goes bad, its transparency will decrease and it will become turbid. This is because the yeast in the juice causes alcohol fermentation and causes the deterioration. Therefore, you should check the texture of the juice every day. If you find that it is turbid, don't be stubborn because it may have gone bad.

2. Smell

You can also identify whether the juice has gone bad by smelling it, especially those juices that show signs of turbidity. After opening the bottle, you will smell a strong smell of alcohol. At this time, you can completely conclude that the juice in the bottle has gone bad. The yeast it contains has regained its reproductive ability, allowing the juice to ferment again, causing the juice to go bad.

3. Taste

To identify whether the juice has gone bad, you can also taste it. Most juices in life have a certain sour taste, and this sour taste mainly comes from the tartaric acid, malic acid or citric acid in the juice. After scientific preparation, the sweet and sour taste of the juice beverage is more appropriate. If you find that the juice tastes abnormally sour when tasting, then it proves that the juice has gone bad and is not suitable for continued drinking. The main reason for the abnormal sour taste of juice is that some bacteria in the juice produce acetic acid or carbon dioxide after decomposition, making its sour taste become sour or have a strong pungent taste.
