How do we keep our roasted cashews from smelling bad eventually?
We are from a small manufacturing unit and do roasting and packing of cashews. After roasting we pack them in polypropylene pouches with nitrogen flushing. But after 2-3 months cashews are smelling bad when packets are opened. Kindly help us learn how to overcome this issue.
Best Answer
Presumably you are experiencing rancidity, due to oxygen.
While you have nitrogen flushed the bags at filling time, the bags are not impervious to oxygen diffusion.
A different type of bag (an "oxygen barrier" bag material) or package (glass jar, or metal can) and, in addition, (based on other packaging I have seen) oxygen absorbing packets inside the bag may be required for long shelf life. Either alone would probably extend the shelf-life somewhat.

Refrigerating or freezing can help them last longer if that is an option. If you choose to go the refrigerator route, the nuts still need to be sealed tightly, as cashews are hygroscopic and will absorb moisture and odors from the environment.Why do my cashews smell weird?

As you already know, cashews can go rancid. And these nuts are much more likely to go rancid that to spoil in the usual meaning of this term. That means when we're talking about shelf life, we're talking about how long they last before they go rancid and lose some of its creamy taste and nutrition value.Should you keep cashews in the fridge?
Long story short, if you keep cashews at room temp, they should keep quality for about half a year, maybe a bit longer. If you go with the fridge, they should last at least a year. If that's not enough, freezing them is the way to go.What Happens To Your Body When You Eat Cashews Every Day

Answer 2
Temperature of the storage area can also be be a significant factor in terms of storage longevity. Nuts will last much longer kept quite cold ( 4 degrees C or less) and even longer when frozen, than they do at room temperatures. Some storage facilities can get very warm at times.
