The shelf life of orange juice after opening depends on whether it's refrigerated or left at room temperature. Here are some general guidelines:
Room temperature storage: Once you open a carton or bottle of orange juice and leave it at room temperature, it's best to consume it within 2 hours. After that time, the juice may start to spoil and could become unsafe to drink due to the growth of bacteria.
Refrigerated storage: If you refrigerate the orange juice after opening, it can typically remain safe to consume for about 7 to 10 days. However, the flavor and quality of the juice may start to decline after a few days. It's always best to check the label on the packaging for any specific instructions from the manufacturer regarding the shelf life of their product after opening.
Keep in mind that these timeframes are general guidelines and can vary based on factors like the quality of the orange juice, how well it was sealed after opening, and the temperature and humidity conditions in your refrigerator.
To extend the shelf life of orange juice, you can transfer it to an airtight container after opening and always keep it refrigerated. Additionally, if you notice any off smells, flavors, or signs of spoilage (such as mold or discoloration), it's best to discard the juice, as consuming spoiled juice can lead to foodborne illnesses.
