I’ve had some mung beans for several years ( I forgot how many) and they still sprouted so that would be a great storage food. I didn’t do anything to them except store them in a glass jar. By the way since everything is going to plastic I save glass jars of various kinds, especially the ones with a little rubber or vinyl seal under the lid. They can be vacuum sealed by putting them in a canister and using the food vacuum sealer if your sealer has the vacuum hose port. Even for regular storage crackers and dry things last longer and taste fresher. I usually seal in canning jars with the attachments for regular and wide mouth.
