Yes, Tang can go bad, but it has a very long shelf life.
While Tang doesn't necessarily "spoil" in the traditional sense, it can degrade in quality over time, mainly in terms of flavor, color, and nutritional value. The primary reason for this degradation is exposure to moisture and air.
-
Shelf Life: Tang typically has a shelf life of around 10 years when stored properly in a cool, dry place, according to the provided reference. This applies to unopened containers.
-
Quality Changes: After its "best by" date, Tang might experience:
- Flavor Loss: The vibrant, tangy flavor may become muted.
- Color Fading: The powder's color could fade.
- Nutrient Degradation: Vitamins, particularly Vitamin C, can degrade over time.
-
Storage: To maximize Tang's shelf life:
- Store unopened containers in a cool, dry place, away from direct sunlight.
- Once opened, reseal the container tightly to prevent moisture absorption.
-
Safety: Even if Tang is past its "best by" date, it is usually safe to consume as long as it looks and smells normal and hasn't been exposed to moisture that could cause clumping or mold growth.
In conclusion, while Tang has a very long shelf life, it is best consumed before its "best by" date to enjoy its optimal flavor and nutritional content. Proper storage is key to maintaining its quality.
