Your almond milk is likely thick because it has gone bad. While thickening isn't the only sign of spoilage, it's a strong indicator.
Here's a breakdown of why almond milk can thicken and what to look for:
-
Spoilage:
- Bacteria can cause almond milk to thicken as it spoils. This is because bacteria consume the sugars and other components in the milk, producing byproducts that alter its texture. A sour smell or taste usually accompanies this thickening.
-
Starch Settling (for homemade almond milk):
- If you've made your own almond milk, the thickness could be due to the natural starches in the almonds settling at the bottom. Be sure to shake the milk very well before each use. If the milk still separates and a layer of thick sediment forms at the bottom even after shaking, it may be starting to spoil.
-
Carrageenan (in some commercial brands):
- Some commercial almond milk brands use carrageenan as a thickener and stabilizer. While carrageenan itself doesn't cause spoilage, changes in its structure (perhaps due to fluctuating temperatures or prolonged storage) could appear as thickening. This is less likely to be the sole reason for the thickness, and it should be coupled with other signs of spoilage like smell and taste.
Other Signs of Almond Milk Spoilage:
| Sign | Description |
|---|---|
| Sour Smell | A noticeable sour or acidic odor. |
| Sour Taste | A tangy or sour taste, even if the smell is not overly apparent. |
| Change in Color | Discoloration or a yellowish tint. |
| Clumps or Curdles | Noticeable clumps or curdled bits in the milk. |
If you observe any of these signs in addition to the thickness, discard the almond milk immediately. Consuming spoiled almond milk can lead to stomach upset or other digestive issues. Even if only slightly thickened, err on the side of caution.
