An example of a UHT (ultra high temperature) food is:

Ultra high temperature (UHT) processing involves heating food to a temperature above 135°C (275°F) for a very short time, effectively killing harmful bacteria and extending shelf life without the need for refrigeration. This method is particularly effective for liquid foods.

Some types of coffee creamers, especially those that are non-dairy and shelf-stable, are processed using UHT techniques. This allows them to be stored at room temperature for extended periods while retaining quality and safety. The high-temperature processing effectively eliminates microbial growth, making these creamers safe for consumption without the usual refrigeration requirements.

In contrast, gourmet canned foods, while they may undergo different types of heat processing, are not typically classified under UHT since they are often pressure canned at lower temperatures. Vacuum-sealed potato chips rely on packaging to keep them fresh but do not utilize UHT processing, as they are dry goods that do not require sterilization in the same manner. Hard candy does not need UHT treatment either, as its high sugar content helps prevent microbial growth, allowing it to be stored safely without refrigeration.

Therefore, the selection of some types of coffee creamers as an example of a UHT food is accurate due to their processing method and shelf stability.
