Macadamia nuts are a type of nut with high nutritional value and delicious flavor. However, if you do not know how to preserve them properly, macadamia nuts can easily become oily, reducing their quality and nutritional value. In this article, Sunshine Macadamia nuts will guide you on how to preserve macadamia nuts without oil smell and are always fresh.

Why are macadamia nuts susceptible to oily odor? Reason

Macadamia nuts contain high levels of unsaturated fats, making them susceptible to oxidation when exposed to air, light and high temperatures. When oxidized, these fats will decompose, creating an unpleasant oily odor. There are many reasons why macadamia nuts become oily, specifically:

• Exposure to air and high humidity

When macadamia nuts are exposed to air and high humidity, the fats in the nuts can oxidize, leading to an oily smell.

• Storage temperature is not suitable

Macadamia nuts need to be stored at a cool, stable temperature. If the seeds are left in a place with high temperatures, the fat in the seeds will easily decompose and cause a bad smell.

• Strong light shines directly on the seeds

Strong light, especially sunlight, can increase the oxidation of fats in the seeds, leading to oily seeds.

Can macadamia nuts with oily odor still be eaten?

Oily macadamia nuts are often due to poor storage, leading to oxidation of the nuts. When macadamia nuts become oily, they not only lose their natural flavor but can also be harmful to your health if consumed.

Therefore, it is best not to eat macadamia nuts with oily smell. If you discover that macadamia nuts have an oily smell, you should throw them away to ensure health safety.

Methods of preserving macadamia nuts to avoid oily smell

Store macadamia nuts at room temperature

To store macadamia nuts at room temperature, you should place macadamia nuts in a cool, dry place, away from direct light and high temperature places. You can also use airtight packaging such as zip-top bags or sealed jars to minimize exposure to air and moisture.

Store macadamia nuts in the refrigerator

One of the ways to preserve macadamia nuts from being oily is to put macadamia nuts in a sealed box or zip bag and put them in the refrigerator. Refrigeration helps maintain grain freshness longer and prevents oxidation.

Store macadamia nuts in the freezer

If you buy macadamia nuts in bulk and don't have time to eat them right away, you can place the macadamia nuts in a zip bag or airtight container for long-term storage in the freezer. Freezing is the most long-term preservation method, helping to maintain the flavor and quality of the seeds for a long time. When you want to use, just leave the seeds out to defrost naturally or in the refrigerator overnight.

Vacuum packaging to preserve macadamia nuts

Using a vacuum cleaner to remove air from packaging containing macadamia nuts is a commonly used method of preserving food in general and macadamia nuts in particular. This method helps prevent oxidation and prolongs preservation time very well.

Vacuum-packed macadamia nuts can be stored at room temperature, refrigerator, or freezer to ensure the best quality.
