Seal yogurt containers tightly after each use to protect against air exposure and cross-contamination from other foods. If yogurt develops an off-odor, unusual color, or mold, discard it immediately.
When portioning yogurt, transfer desired amounts to separate containers rather than eating directly from the original packaging. This practice reduces the risk of contamination and helps maintain freshness for the remaining product.
Recognizing Spoilage
Plant-based yogurt can show clear signs of spoilage through visual, olfactory, and physical changes. Knowing these indicators helps consumers determine if their yogurt is still safe to eat.
Visual and Olfactory Signs
Mold growth is a definitive sign that plant-based yogurt has spoiled. Look for fuzzy spots on the surface, which may appear in various colors like green, blue, or black. These indicate the yogurt is no longer safe for consumption.
A sour smell that’s stronger than the yogurt’s typical tangy scent suggests spoilage. Fresh plant-based yogurt should have a mild, pleasant aroma. If it smells unpleasant or off-putting, it’s best to discard it.
Separation beyond the normal settling of liquid on top can also indicate spoilage. While some separation is normal, excessive liquid or a curdled appearance may mean the yogurt has gone bad.
Physical Indicators of Spoilage
Texture changes are key indicators of spoiled plant-based yogurt. Fresh yogurt should have a smooth, creamy consistency. If it becomes lumpy, grainy, or excessively watery, it may have spoiled.
A sour taste that’s more intense than the yogurt’s usual tanginess is a sign of spoilage. If the flavor is unusually sharp or unpleasant, it’s safer not to consume it.
