Why are black olives always in a can?
Black olives are most often canned because it is a convenient and cost-effective way to package and preserve them. There are a few factors that make canned black olives a preferred form of packaging for this product.
First, the canning process helps to extend the shelf life of the olives, making them available all year round. The thermal process used to can olives uses steam and pressure to reach an extremely high temperature.
This kills bacteria and other organisms, which helps to preserve the olives. By canning the olives, they can typically last for up to three years without losing any flavor, texture, or nutritional value.
Additionally, canning helps to protect the olives from air and light exposure which could cause oxidation resulting in off-flavors. The process of canning requires vacuum sealing of the olives, which then prevents the olives from going bad quickly due to their high oil content.
Finally, for both the manufacturer and consumer, canned olives are more cost-effective than fresh, due to the fact that they can be stored for longer periods of time and less product is typically lost due to spoilage.
Manufacturers can purchase large volumes of olives and can them, meaning that no fresh olives need to be bought to meet customer demand. This helps to keep prices more affordable.
