Yogurt comes in two types: regular-temperature yogurt and low-temperature yogurt. Regular-temperature yogurt has undergone special processing and can be preserved for 3 to 6 months at room temperature, but its nutrition and taste are not as good as low-temperature yogurt. Low-temperature yogurt really needs to be kept fresh. Once it goes bad, it can cause unhealthy phenomena for consumers. Now let's introduce how to store low-temperature yogurt.
Room temperature storage:
Low-temperature yogurt contains live bacteria beneficial to the intestines. Storage at 0 - 4°C is the best, so try not to store it at room temperature. If stored at room temperature, it should not exceed 2 hours. If the room temperature exceeds 32 degrees Celsius, it should be limited to 1 hour.
Refrigerated storage:
Refrigeration is the most suitable way to store low-temperature yogurt. Yogurt stored in the refrigerator has a shelf life of about 10 - 21 days. The purchase should be based on the shelf life on the product packaging.
Frozen storage:
When frozen, the lactic acid bacteria in low-temperature yogurt will be in a dormant state and will not continue to ferment. After thawing, the lactic acid bacteria will still ferment. Therefore, low-temperature yogurt can also be stored frozen.
The shelf life in frozen storage can generally reach about 1 month.

How to tell if it's gone bad?
Some basic characteristics of spoiled yogurt:
No curd, in a liquid state.
Too strong sour taste or an alcoholic fermentation smell.
There are bubbles.
There is a musty smell.
The color turns dark yellow or green.
Spoiled yogurt is not edible.

Summary:
The best way to store low-temperature yogurt is refrigeration.
Low-temperature yogurt is very likely to go bad at room temperature. After taking it out of the refrigerator, it should be drunk as soon as possible.
If long-term storage is needed, low-temperature yogurt can also be stored frozen.

A guide to storing low-temperature yogurt: Keeping it fresh for longer
Among the many beverages, low-temperature yogurt is loved by people for its rich nutrition and unique taste.
Low-temperature yogurt has a very high nutritional value. It is rich in high-quality protein, which is an important source of substances for the human body to maintain life activities, growth and development. At the same time, yogurt is rich in calcium, which is essential for bone health and can effectively prevent diseases such as osteoporosis. In addition, the active lactic acid bacteria in yogurt are a highlight, which can regulate the balance of intestinal flora, promote digestion and absorption, enhance human immunity, and reduce the occurrence of intestinal diseases.
However, in order to enjoy the delicious taste of low-temperature yogurt, it is important to store it correctly.

1. The importance and characteristics of low-temperature yogurt
Low-temperature yogurt not only has a mellow taste, but also contains a variety of nutrients, such as protein, calcium, vitamins, etc. Among them, active lactic acid bacteria are a major feature of low-temperature yogurt, which has many benefits for human intestinal health, such as promoting digestion and enhancing immunity. However, these active lactic acid bacteria have high environmental requirements and need to maintain their activity at low temperatures.

2. The correct way to preserve
(1) Refrigerate in time after purchase
When you buy low-temperature yoghurt from a supermarket or store, you should store it in the refrigerator at 4 - 10 degrees Celsius as soon as possible. This ensures that the active lactic acid bacteria in the yogurt remain active and also extends the shelf life of the yogurt. Also, try to avoid buying expiring products to avoid premature spoilage of yogurt during preservation.
(2) Place deep in the refrigerator
Frequent opening and closing of refrigerator doors can cause temperature fluctuations that affect the preservation of yogurt. Therefore, it is best to keep the low-temperature yogurt deep in the refrigerator. The temperature here is relatively more constant, providing a stable storage environment for yogurt.
(3) Drink as soon as possible after opening
Once the packaging of low-temperature yogurt is opened, airborne bacteria begin to invade, causing the yogurt to spoil faster. Therefore, the yogurt should be drunk as soon as possible after opening. If you can't drink it all at once, you can seal the remaining yogurt and put it back in the refrigerator, but also drink it in a shorter time.

3. How to judge whether yogurt has gone bad
"One look"
First look at the expiration date and make sure the yogurt is within the expiration date. At the same time, observe the color and homogeneity of the yogurt. Normal low-temperature yogurt has a uniform color and a delicate texture. If you notice that the yogurt is abnormal in color or layered, it may be that the yogurt has gone bad.
"Second Taste"
Taste the yogurt. Fresh, low-temperature yogurt has a moderate sweet and sour taste, and if it tastes sour, bitter, or has an off-flavor, it may have gone bad.
"Three Observations"
Observe how your body reacts after drinking. If you experience abdominal pain, diarrhea and other uncomfortable symptoms after drinking yogurt, it may be caused by yogurt spoilage. At this time, you should stop drinking immediately and seek medical attention promptly.

4. Handling under Special Circumstances
(1) People who are sensitive to cold
For some people who don't like to eat raw and cold foods or are sensitive to cold, you can leave the yogurt at room temperature for a while to allow it to warm up slightly before drinking. However, it should be noted that the yogurt should not be left for too long to avoid the yogurt spoiling. You can also heat the yogurt moderately with warm water, but the water temperature should not be too high, and it is best to control it below 40 degrees Celsius to avoid destroying the active lactic acid bacteria in the yogurt.
(2) The storage time limit at room temperature
If low-temperature yogurt is left at room temperature, its shelf life will be greatly reduced. Generally, at room temperature around 25 degrees Celsius, low-temperature yogurt can last for 2 - 3 hours; At 30 degrees, the shelf life may be shorter, around 1 - 2 hours. When storing yogurt at room temperature, try to avoid direct sunlight and put it back in the refrigerator as soon as possible.
In conclusion, keeping low-temperature yogurt right allows us to better enjoy its delicious taste and nutrition. Hopefully, the above saving methods and tips can be helpful to you
