In an April 5, 2021 article, "7 foods you should be storing in the freezer, including yeast, nuts and peppers", Washington Post author Becky Krystal offers advice for freezer storage of common food items such as yeast, tomato paste, ginger, hot peppers and whole-grain flours to increase their shelf life and cut down on wasted food.  She includes nuts and nut flours as prime candidates for refrigeration/freezer storage due to their fatty oil content, and links to the University of California Agriculture and Natural Resources (UCANR) publication 8406, "Nuts:  Safe Methods for Consumers to Handle, Store, and Enjoy Almonds, Chestnuts, Pecans, Pistachios, and Walnuts (PDF 4.76 MB).  This workhorse of a publication was a collaboration between authors at FST/UCANR, Western Human Nutrition Research Center, and UCCE Yolo & Solano Counties in 2010.  You can find many others like it on the UCANR Catalog page here:  https://anrcatalog.ucanr.edu/ and on the Consumers tab of the UC Food Safety website (the website of FST's Erin DiCaprio and Linda J. Harris) as well.
