Final answer:
Milk can be received at 45 degrees if it has undergone ultra-high-temperature (UHT) pasteurization, which sterilizes the milk, allowing it to be sealed and stored without refrigeration for up to 90 days.
Step-by-step explanation:
Milk can be received at 45 degrees under specific conditions related to ultra-high-temperature (UHT) pasteurization. UHT pasteurization exposes milk to ultra-high temperatures, around 138 °C for 2 or more seconds, effectively sterilizing it. After this process, the milk can be sealed in airtight containers and stored for up to 90 days without refrigeration. Although most milk should be received at temperatures much lower than 45 degrees to ensure freshness and prevent spoilage, UHT pasteurized milk is an exception due to its high-temperature processing and sterile packaging.
The milk can be received at 45 degrees under the condition of UHT (Ultra-High Temperature) pasteurization. This method exposes milk to ultra-high temperatures, close to 138 °C, for a few seconds, effectively sterilizing it so that it can be sealed and stored for long periods without refrigeration. UHT pasteurized milk is able to maintain its quality and freshness even at room temperature.
