Cashew milk's shelf life depends heavily on whether it's commercially packaged or homemade.
Commercially Packaged Cashew Milk
Unopened, commercially packaged cashew milk can last for two months or longer, according to a 2021 study in Food Science and Technology. Once opened, however, its shelf life significantly reduces to approximately one week. After this time, the risk of food poisoning increases.
Homemade Cashew Milk
Homemade cashew milk is considerably less stable than commercially produced varieties. Multiple sources indicate a shelf life of only 3-5 days when refrigerated in an airtight container. Many recommend consuming it within the first 2-3 days for optimal flavor and freshness. Storing it in an airtight glass jar in the refrigerator is crucial for extending its shelf life. Going beyond 7 days is generally not recommended.
Factors Affecting Shelf Life
Several factors influence how long cashew milk remains safe and palatable:
- Storage: Always refrigerate cashew milk in an airtight container to prevent spoilage.
- Freshness of Ingredients: Using fresh ingredients helps maintain quality and extends the shelf life.
- Temperature: Exposure to heat accelerates spoilage. Keep cashew milk away from direct sunlight and heat sources.
In Summary
To recap:
- Store-bought (unopened): 2 months or more.
- Store-bought (opened): About 1 week.
- Homemade: 3-5 days, ideally consumed within 2-3 days.
