When did food preservation start which year is it?

Answer 1

Meat has been preserved for centuries by packing it in salt and/or other spices. In the early 1800s, Napoleon offered an award for a means of preserving food in convenient containers that his army could take with them. In response, an individual (whose name escapes me) developed the process of preserving cooked food in wine bottles. Later, tin and then steel cans were used.

Answer 2

The preservation of food started with earliest man when their food froze or was dried out by a fire. Modern food preservation started when Napoleon offered a reward to whomever found a way to keep fresh for his armies. As they were on the move constantly they needed a reliable way to transport large quantities of food for an extended period of time.
