How to store yogurt at home and detect spoiled yogurt
The best way to store yogurt for a long time and preserve its taste and quality is to place it in the refrigerator at a temperature of 5 to 7 degrees Celsius and in ordinary containers of clay, glass or plastic.
Housekeeping star - although yogurt spoils later than milk and is said to be able to be consumed up to three weeks past the expiration date, but that is if you are familiar with how you store yogurt and the proper container for it. In this article, we explain how to store yogurt, the proper container, and how to identify spoiled yogurt.
Yogurt preservation method
To store yoghurt, whether it is pasteurized or homemade yoghurt, it is necessary to store it in the refrigerator at a temperature of 5 to 7 degrees Celsius. At this temperature, the growth rate of mold decreases and the yogurt can be stored for a longer period. Avoid storing yogurt at room temperature and against sunlight.
The best yogurt storage container
The best container for storing yogurt for a long time and preserving its taste and quality is a clay container known as a yogurt jar. Clay containers have a very high suction property, and because of this property they absorb excess water in the yoghurt, and as a result, the yoghurt production is curdled. This yogurt has a very delicious taste and is rich in calories.
Important note: Always use yellow or colorless packaging when choosing terracotta containers for storing yogurt, as the blue and turquoise colors used in terracotta containers contain lead.
It's also safe to store yogurt in standard, light-colored glass jars and plastic containers.
Methods for detecting spoiled yogurt
1- Pour the yogurt
One of the most important signs of spoiled yogurt is the appearance of green and brown spots on the yogurt, which indicates mold growth. Molds are most active at 20-25°C; Do not store yogurt outside the refrigerator.
Tip: Avoid using moldy yogurt and note that if it is moldy, you should throw it all away, because although you may not see the discolored spots in some parts, the mold has spread everywhere in the container.
2- The smell of curd
One of the first signs of food spoilage is a change in smell. In the case of yoghurt, if you feel an unpleasant smell similar to curd, then make sure that the yoghurt is spoiled.
3- A change in taste
Yogurt tastes bitter due to spoilage. This is caused by chemical reactions and the hydrolysis of yogurt proteins into bitter-tasting amino acids. Therefore, avoid eating bitter yogurt, but if the yogurt is only sour, then it is not spoiled, but it does not contain the same nutritional value.
The conclusion
If you know how to store yogurt properly, you can use it for a few weeks after the expiration date and don't have to throw it away. Avoid moldy yogurt with green and brown spots, yogurt that tastes bitter, and yogurt that smells like curd, and always buy yogurt in small quantities.
