Why Some Food Storage Won’t Last – Double Enamel Cans
In our previous installment on Why Some Food Storage Products Won’t Last we covered the importance of a good can seam and how a poor seam will lead to increased levels of oxygen over time which results in food spoiling early. Today we are going to look at another element of the can, the necessity of a double sided enamel coating.
There are two main reasons to use a double enameled can, first the flavor of your food is preserved by creating a layer between the steel and the food. Without the layer the food will take on the taste of the steel can over time.
The other benefit is preventing rust both internally and externally. Moisture coming in contact with metal will lead to rust which over time jeopardizes the can’s ability to create the ideal atmosphere for the food contained inside.
While double enamel cans cost more (and some companies skimp by going with a one sided enamel) you shouldn’t settle for anything less. You need to make sure that your food storage #10 cans comes with external and internal enamel coated walls so you can maximize the shelf-life of your food storage.Updated December 2, 2011
