## Why does vacuum packed ham have air?
1. **Why does vacuum packed ham have air?**.
When we purchase vacuum packed ham, we might notice that there is some air inside the packaging along with the ham itself. It seems contradictory to the concept of vacuum packing, which is supposed to remove all air. .
2. **Explanation**.
The presence of air in vacuum packed ham is actually intentional and serves a specific purpose. While the packaging removes most of the air to extend the shelf life of the ham and prevent spoilage, a small amount of air is intentionally left inside. This residual air helps cushion the ham during transportation and handling, preventing the slices from being crushed or deformed.
Additionally, the presence of a small amount of air can also help maintain the shape and texture of the ham. Without any air at all, the ham slices might stick together and lose their appealing appearance. The air inside the packaging acts as a protective barrier and ensures that the ham slices remain separate and intact until they are opened and served.
In summary, the presence of air in vacuum packed ham is a deliberate choice to protect the integrity of the product during storage and transportation. It serves as a cushion and a barrier to maintain the shape and quality of the ham slices until they are ready to be enjoyed.
