Yes, citrus juice goes bad. The shelf life depends on whether it's freshly squeezed or store-bought and pasteurized.
Here's a breakdown:
-
Freshly Squeezed Citrus Juice: This type of juice is highly perishable because it hasn't undergone any preservation processes.
- Shelf Life: It generally lasts for up to 4 days in the refrigerator when stored in an airtight container.
- Storage: Keeping it properly sealed is crucial to minimize oxidation and bacterial growth.
-
Pasteurized Store-Bought Citrus Juice: Pasteurization is a heat treatment that kills harmful bacteria and extends shelf life.
- Shelf Life: Unopened, it can typically last for 3-6 months in the pantry. Once opened, or if stored in the refrigerator from the start, it can last up to 1 year in the fridge.
- Storage: Always store opened juice in the refrigerator and tightly sealed to prevent spoilage.
Factors Affecting Spoilage:
- Storage Temperature: Higher temperatures accelerate spoilage.
- Exposure to Air: Oxidation can degrade the flavor and nutrients.
- Contamination: Introducing bacteria can lead to rapid spoilage.
Signs of Spoilage:
- Off Odor: A sour, fermented, or otherwise unpleasant smell.
- Discoloration: Any unusual darkening or changes in color.
- Changes in Texture: Slimey or chunky appearance.
- Mold Growth: Visible mold indicates spoilage.
- Sour Taste: An obviously sour or "off" taste.
If you notice any of these signs, it's best to discard the juice to avoid potential health risks.
