How to Keep Macadamia Nuts Fresh
Moisture and Oxygen
Dried macadamia nuts should be protected from moisture throughout the storage process, as moisture makes the nuts lose their crispness and shortens storage life. Oxygen will cause rancidity if the exposure is prolonged. If you store macadamias on the shelf in your pantry, they will be edible for two to four weeks, according to the Still Tasty website. Once you open the original packaging, place the nuts in an airtight container or resealable plastic bag to protect them from air and moisture.
Although cold storage is not necessary when macadamias will be eaten within a week or two, if you want to store your macadamia nuts for an extended period,
cold storage or freezing will extend shelf life. Refrigeration extends the shelf life to six months and frozen macadamia nuts will keep for nine months to one year, according to the Still Tasty website. Package the nuts to prevent air from getting into the package and use a moisture proof storage container such as a plastic freezer container or heavy duty freezer bag. The price, which is often double that of nuts such as cashews, reflects the high demand and relatively low supply. Storing your nuts carefully will ensure that you get your money’s worth and that your nuts will provide you with the best possible taste and texture. However, if your nuts have an off flavor or odor, they should be discarded no matter how carefully they were stored.
