Understanding the importance of double-sided enamel coatings in food storage cans will help you preserve flavor and extend shelf life.
In our previous installment, "Why Some Food Storage Products Won’t Last", we discussed how poor can seams can increase oxygen exposure, leading to premature food spoilage. Today, we’ll focus on another critical element of food storage: the necessity of a double-sided enamel coating.
Why Use Double-Sided Enamel Coating?
There are two primary reasons why a double-enameled can is essential for food storage:
- Preserving Food Flavor: A double-sided enamel coating creates a protective layer between the steel can and the food. Without this layer, food stored over time may absorb the metallic taste of the steel, compromising its flavor and quality.
- Preventing Rust: Moisture that comes into contact with untreated metal can lead to rust, both internally and externally. Rust weakens the can’s structure, jeopardizing its ability to maintain a proper storage atmosphere.
The Long-Term Value of Double-Sided Enamel
While double-enamel coated cans come at a higher production cost, some companies cut corners by using single-sided enamel coatings to save money. This compromises the long-term safety and taste of the food.
When selecting food storage supplies, don’t settle for anything less. Ensure your #10 cans feature both external and internal enamel coatings to maximize shelf life and protect your food investment.
