Canning food

In 1795, a prize of 12,000 francs was offered by the French government for a method of preserving food and transporting it to its armies. The winner was Nicholas Appert, a French chef who invents a way to can food. He developed the method of heating food in airtight glass jars, not very different from the home-bottling method now uses Mason jars. He published The art of preserving animal and vegetable substances for several years, in Paris, 1801. He was also the inventor of the bouillon cube.
