As a food safety expert with years of experience in the field, I can provide you with a comprehensive guide on how to determine if peanut butter has gone bad. The quality and safety of peanut butter are crucial, as it is a staple in many households and a popular ingredient in numerous recipes. Here are several key indicators to look for:
1. Visual Inspection:
The first step in assessing the condition of peanut butter is to visually inspect the jar. If you notice any mold, particularly a fuzzy white or green substance, it's a clear sign that the peanut butter is no longer safe to consume. Additionally, a change in color from a creamy, light brown to a darker, more uneven hue can indicate spoilage.
2. Texture:
Good quality peanut butter should have a smooth and creamy texture. If you find the peanut butter has become hard, dry, or crumbly, it may be a sign that it has lost its quality. This change in texture can be due to the separation of oils, which can occur over time, especially if the jar has been stored improperly.
3. Aroma:
Peanut butter has a distinct and pleasant aroma. If you open the jar and the peanut butter smells rancid or off, it's a strong indication that it has gone bad. The absence of the characteristic nutty smell is another red flag.
4. Taste:
While it's not always safe to taste suspect food products, if you're confident that the peanut butter hasn't been contaminated by mold or other harmful substances, a small taste can be telling. Spoiled peanut butter will have an unpleasant, rancid flavor.
5. Separation of Oil:
It's normal for oils to separate in natural peanut butter over time. This can be observed as a layer of oil floating on top of the peanut paste. While this doesn't necessarily mean the peanut butter is bad, it does indicate that the product needs to be stirred well before use. However, if the separation appears excessive or the oil has a different color or smell, it could be a sign of spoilage.
6. Expiration Date:
Always check the expiration or best-by date on the jar. While peanut butter can last beyond these dates, especially if it has been stored properly, consuming it after the date has passed increases the risk of foodborne illness.
7. Storage Conditions:
The way peanut butter is stored can greatly affect its shelf life. It should be kept in a cool, dry place away from direct sunlight. If the jar has been exposed to heat or moisture, it can spoil more quickly.
8. Presence of Additives:
Some peanut butter brands include additives to extend shelf life. While these additives can delay spoilage, they do not guarantee that the product will remain safe indefinitely. Always use your senses and judgment in addition to relying on additives.
In conclusion, the most reliable way to determine if peanut butter is bad is through a combination of sight, smell, and taste, along with considering the storage conditions and the product's expiration date. When in doubt, it's always safer to err on the side of caution and discard the product.

Sight is usually the most reliable way to tell if your peanut butter has gone bad. A common trait of bad peanut butter is a change in texture from soft and creamy to hard and dry.
