UHT cream is cream that has been ultra-heat treated (UHT) to extend its shelf life. It's also known as long-life cream.
Here's a breakdown of what that means:
-
UHT Treatment: The cream is heated to a high temperature (around 135°C or 275°F) for a very short period (typically 2-5 seconds). This kills most of the bacteria and spores present, which are responsible for spoilage.
-
Aseptic Packaging: Immediately after heating, the cream is packaged in sterilized, airtight containers, often Tetra Pak cartons. This prevents new bacteria from entering and contaminating the product.
-
Extended Shelf Life: The combination of UHT treatment and aseptic packaging allows UHT cream to be stored at room temperature for several months, unopened. Once opened, it must be refrigerated and used within a few days, similar to fresh cream.
Key Characteristics of UHT Cream:
- Long Shelf Life: The primary benefit is its extended shelf life compared to fresh cream.
- Storage: Can be stored at room temperature until opened.
- Flavor: Some people perceive a slightly cooked or different flavor compared to fresh cream due to the high-temperature treatment. The extent of this flavor difference can vary between brands.
- Functionality: UHT cream can be used in many of the same ways as fresh cream, such as in coffee, sauces, and desserts. However, its whipping ability may be affected by the UHT process; some UHT creams whip well, while others don't. Read the packaging to see if the specific brand is appropriate for whipping.
In short, UHT cream is a convenient and shelf-stable option for those who don't use cream frequently or who need a longer shelf life.
