What’s the shelf life of refrigerated nut pastes?

Question

Discover how long nut-based pastes last in the fridge and how to store them.

Answer 1

Refrigerated nut pastes, such as almond butter or cashew butter, typically last for 2-3 months after opening, provided they are stored properly. Unopened, they can last up to a year, depending on the expiration date.

Detailed Explanation:

The shelf life of refrigerated nut pastes is influenced by several factors, including the type of nut, the presence of preservatives, and storage conditions. Nut pastes contain natural oils that can become rancid over time, especially when exposed to air and light. Refrigeration helps to slow down this process.

Here's a breakdown of the typical shelf life:

1. Unopened Nut Pastes: Most commercially produced nut pastes have a 'best by' or 'expiration' date printed on the jar. If stored in a cool, dark place, they can often last until that date, which can be up to a year from the manufacturing date.

2. Opened Nut Pastes (Refrigerated): Once opened, nut pastes should be refrigerated to maintain their quality and prevent spoilage. Under refrigeration, they generally last for 2-3 months. Look for signs of spoilage, such as a change in smell, taste, or texture (e.g., excessive oil separation or mold growth).

3. Natural or Homemade Nut Pastes: Nut pastes without preservatives tend to have a shorter shelf life. They should be refrigerated immediately after preparation and consumed within 1-2 months.

Pro Tip:

To extend the shelf life of your nut pastes, store them upside down in the refrigerator. This helps to redistribute the oils and prevent them from separating and going rancid on the surface.
