| Soy Milk | 7-10 days (refrigerated), 30-60 days (shelf-stable) |
| Oat Milk | 7-10 days (refrigerated), 30-60 days (shelf-stable) |
As shown in the table, the shelf life of milk varies depending on the type and storage conditions. In general, cow’s milk has a shorter shelf life compared to alternative milk options like almond milk, soy milk, and oat milk. However, it’s essential to note that the shelf life of milk can be extended by proper storage and handling practices.
Extending the Shelf Life of Milk
There are several ways to extend the shelf life of milk, including freezing, ultra-pasteurization, and aseptic packaging. Freezing milk can help preserve its nutritional value and extend its shelf life for several months. Ultra-pasteurization, which involves heating the milk to a high temperature for a short period, can also help kill off bacteria and extend the shelf life. Aseptic packaging, which involves filling and sealing the milk in a sterile environment, can help prevent contamination and spoilage.
Best Practices for Storing Milk
To maximize the shelf life of milk, it’s essential to follow best practices for storing and handling. This includes storing the milk in a cool, dry place, away from direct sunlight and heat sources.
