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.(http://www.bccancer.bc.ca/NR/rdonlyres/75D25772-8F87-4C8C-9BA2-8600AB07591C/56470/EWBAEnglish.pdf). This is an even bigger concern than rancidity. It scares me that you have not done adequate research before posting these recommendations.
