When someone told me to keep my nuts in the freezer, I thought they were nuts themselves! When I found out the intricate details as to why, it all made sense.
IT’S ALL IN THE OIL
It’s the oils in nuts and seeds that make them go stale (and sometimes mouldy) quite quickly. Which when you think about it, makes complete sense. Oil by itself goes rancid through various chemical reactions. Due to the oil in your nuts and seeds, when exposing them to light, heat and air makes them go rancid even quicker.
If you want your nuts and seeds to last longer, store them in the fridge or freeze in an airtight container, this slows down the stale and rancidity rate. If stored in the fridge, nuts and seeds will last around 4-6 months longer than keeping them on a shelf in the pantry. If storing them in the freezer, the expiry will last as long as 6-12 months, depending on the type of nuts and how fresh they were when originally purchased.
IT’S NOT JUST FOR FRESHNESS
Keeping nuts in the fridge and/or freezer will also keep them tasting sweeter, it prevents them from absorbing the smell and taste of surrounding foods, therefore all round better tasting and better for you..
The best thing about storing your nuts in the freezer is that they do not freeze completely hard so you do not have to thaw nuts before use. They can simply be used or eaten directly out of the freezer
