Fountain pop syrup doesn't necessarily "go bad" in the sense of becoming unsafe to consume, provided the container remains intact and free from impurities. However, its quality – specifically taste and color – can degrade over time.
Here's a more detailed breakdown:
-
Safety: The high sugar content in fountain syrups acts as a preservative. As long as the syrup is stored properly (sealed and away from contaminants), it shouldn't harbor harmful bacteria or mold. Essentially, it's unlikely to make you sick.
-
Quality Degradation: Over time, several factors can affect the quality of fountain syrup:
- Flavor Loss: The syrup's flavor compounds can degrade, resulting in a less intense or altered taste. This is more noticeable with delicate flavors.
- Color Change: Exposure to light and air can cause the syrup to darken or change color. This affects the visual appeal of the final beverage.
- Crystallization: If not stored properly, the sugar in the syrup can crystallize, affecting its texture and how it mixes with carbonated water.
-
Signs of Spoilage: While uncommon, watch out for these signs that indicate the syrup may be compromised:
- Visible Mold: Any presence of mold means the syrup should be discarded.
- Fermentation: A sour or alcoholic smell suggests fermentation, indicating spoilage.
- Bloated Container: A bulging or bloated container might suggest the syrup has fermented and is producing gas.
In short: Fountain pop syrup is generally safe to consume indefinitely if stored correctly, but its taste and color may diminish over time. Discard if you notice any signs of mold, fermentation, or a bulging container.
