On the market today, there are many different brands of yogurt such as Fristi, Vinamilk, Probi, and TH True Milk, each with various flavors that children love. Additionally, many skilled housewives also make their own yogurt to meet their family’s needs. To ensure the yogurt remains delicious and nutritious, proper preservation is necessary.
1 How to properly preserve homemade yogurt
According to PGS.TS Nguyễn Duy Thịnh from the Institute of Biotechnology & Food Technology at Hanoi University of Technology, homemade yogurt is prone to mixing with bacteria during the fermentation process, leading to a rapid souring and spoilage. Therefore, homemade yogurt should be consumed within 2 days.
If you want to extend the shelf life of homemade yogurt, store it in the cool compartment of the refrigerator at a temperature of about 8 degrees Celsius. The lower temperature slows down the fermentation process, allowing the yogurt to remain fresh for a longer period and reducing the risk of bacterial contamination.
When making yogurt, it is advisable to use a glass jar for storage to ensure safety and prevent harmful substances from penetrating the yogurt over time, which can have negative effects on your health.
2 How to properly preserve branded yogurt
Branded yogurts usually undergo a production process that ensures hygiene and safety. As a result, branded yogurt can be preserved for a longer period compared to homemade yogurt. However, it is still important to follow proper yogurt preservation techniques.
Each type of yogurt has different characteristics in terms of consistency, composition, and flavor. When purchasing yogurt, carefully read the product information to determine the most suitable temperature for preservation. Typically, yogurt should be stored at a temperature of 6-8 degrees Celsius.
Avoid exposing yogurt to direct sunlight and promptly place it in the refrigerator after purchase.
When stored in the refrigerator, yogurt can last for 1-2 weeks, but it is recommended to consume it within 1 week of purchase for optimal quality.
3 Notes on yogurt preservation
Despite knowing how to properly preserve yogurt, it is still important to pay attention to the product’s shelf life. For branded yogurt, the expiration date is usually printed on the bottom of the container.
Freezing yogurt is an option for some households; however, this can result in the destruction of beneficial bacteria and the separation of water from the yogurt, leading to an altered taste. Therefore, it is not recommended to store yogurt in the freezer.
It is advisable not to purchase yogurt products sold in non-refrigerated stores as yogurt needs to be continuously stored at a temperature of 4-8 degrees Celsius to maintain its quality.
For partially consumed yogurt jars, it is best to close the lid tightly and store them in the cool compartment of the refrigerator. Leaving yogurt outside can cause it to spoil the next day.
