Macadamia nuts are known for their delicate, buttery flavour and creamy texture. Like many nuts and seeds, they taste best when they have been stored correctly and kept fresh.  

There are a few reasons why nuts, including macadamia nuts, may lose their freshness. This includes the nut being exposed to excessive heat, light, and air. Exposure to moisture can also impact nut quality.  

When a nut has been negatively exposed to one of the above it may go rancid. A rancid nut may look less plump than usual and will taste unpleasant. Rancidification can also detract from the nutritional value of food, as some vitamins are sensitive to oxidation. 

One of the primary reasons that macadamia nuts go rancid is due to their high fat content. Sooner or later all foods that contain fat will go rancid, as fats turn bad more quickly than other types of nutrients.  

To extend the shelf life of macadamias we recommend the following: 

Store in an airtight container: One of the most important things you can do to extend the shelf life of macadamia nuts is to store them in an airtight container. This will keep out air and moisture that can cause the nuts to spoil. 

Keep them in the refrigerator: Macadamia nuts are sensitive to temperature and should be stored in the refrigerator to help maintain their freshness. They will last for several months when stored this way. 

Keep them in the freezer: If you plan on storing macadamia nuts for an extended period of time, freezing is a good option. They will last for up to 6 months when stored in the freezer. Just be sure to place them in an airtight container and remove as much air as possible before sealing. 

Avoid light exposure: Sunlight and UV light can cause macadamia nuts to go rancid and shorten their shelf life. Keep nuts in a cool, dark place in a sealed container. 

Inspection: Before purchasing or consuming macadamia nuts, always inspect them first. If you notice any unpleasant smell or discolouration, it is best to discard them. Always opt for buying macadamias from a reputable source and check the packaging for any signs of damage before purchase. 

By following these tips, you can help to ensure that your macadamia nuts remain fresh and delicious for as long as possible. Remember, when in doubt, always trust your senses such as smell, appearance and taste to know if they are still fresh.
