Macadamia nuts will last approximately 3 months if you keep them in the fridge. Since they will no longer be in their original packaging, it's important that you write the date of purchase on the package. The University of California (UOC) states that macadamia beans last about five months at room temperature, 12 in the fridge and 24 when frozen. And those estimates are similar to what the labels say on packaged macadamia nuts.
Fortunately, macadamia nuts have a fairly long shelf life when properly stored. Therefore, if you have followed the above measures, your macadamias will be in good condition for up to 6 months in the pantry. However, they can last much longer in the fridge or freezer if you really need them. Macadamia nuts usually last about six months in the pantry and can last up to a year in the fridge and two years if frozen.
The lifespan of macadamia has several factors such as humidity, temperature and storage method. It also depends on the quality of the packaging. Nuts without shells last much longer than those without shells. It should be noted that nuts have no expiration date and, instead, they have an expiration date.
Therefore, it is completely safe to consume macadamias even after the expiration date. Macadamia nuts are healthy for you, but they can go bad if stored improperly. They last a maximum of three months in an airtight container in the refrigerator, although they can also be frozen to stay edible for up to six months. That date is not an expiration date, but rather a good reference point that tells you how long they should maintain the quality of nuts.
Macadamia is native to Australia but is now cultivated in favorable climates around the world, in Hawaii, Brazil, Indonesia and elsewhere. Whether you eat them as a standalone snack or you love to bake with them, macadamia nuts are a delicious treat that can last quite a long time, especially when kept frozen. Place a handful of walnuts there (enough for a week) and, each time you empty it, pour another batch. However, while manufacturers have done us a favor by saving us from these difficulties, nuts in this form are generally not stored for as long as those that still have shells on them.
Macadamia nuts are rich in essential nutrients, such as thiamine (104% DV), B6, pantothenic acid, niacin, riboflavin, etc. This is lower than the average protein content of other nuts, such as almonds (8%), pistachios (9%), walnuts (11%), walnuts (13%) and cashews (14%). Macadamia nuts that are still in their shell can be stored in the freezer and retain their quality for up to 2 years if stored properly. Of course, rancification isn't the only possible reason you might need to throw away macadamia nuts.
When buying unshelled macadamia nuts, look for those that are packaged in a sealed container to avoid any contamination. However, given the successes of the Hawaiian macadamia industry, other subtropical regions have planted orchards and there are large areas of macadamias in South Africa, Zimbabwe and Malawi, as well as in parts of South and Central America. Whole macadamia nuts can survive the elements much better than their unshelled counterparts because they already have a natural shield against elements that can damage them.
