How do you remove the burn smell from food?

I know you can remove it from Vegetables.

First rinse off all the ice off of the veggies. Soak in water with 1/4 to 1/2 cup baking soda. for 30 minutes Pour water out and rinse veggies then Soak in water again with baking soda rinse and repeat until the freezer burn soaks out of veggies. I have saved many freezer burnt veggies.
