Should I Refrigerate My Peanut Butter (Or Any Nut Butter)?

nut butter

A Fooducate community member recently asked about the shelf life of nut butters. Here’s what you need to know.

Peanut, almond, and cashew butters are not only tasty, they are a good source of healthy unsaturated fats. These fats are susceptible to rancidity as a result of oxidation, and that’s why manufacturers recommend refrigeration.

However, the oxidation process is not immediate. If you seal the lid on your nut butter and keep it in a cool dark pantry, you can go for 2-3 months without refrigeration. Another benefit of non-refrigerated storage is that your nut butter will be easier to scoop out of the jar and spread. Always use a clean utensil so as not to introduce any contamination. If you live in an extremely hot area, the refrigerator may be a better choice.

    Good to know. I refrigerate mine, but that’s because I make my own but butter and I haven’t noticed a big difference in spreading.

    If I don’t keep my organic in the fridge, it separates and is a complete mess to try to use.

      My butter also separates in my pantry, but try during the jar upside down.

        I mean storing, not during.

    It’s interesting that you promote storing nut butters at room temperature when Canadian Cancer Society recommends refrigerating nut butters to prevent the growth of carcinogenic aflatoxin.( This is an even bigger concern than rancidity. It scares me that you have not done adequate research before posting these recommendations.
