Towards the end of the eighteenth century, Napoleon offered a reward to anyone who could provide him with a method for keeping food in good condition over long periods of time. It was Nicolás Appert who discovered that food could be preserved for a number of years by heating it in hermetically sealed containers. Thanks to this he was awarded the Benefactor of Humanity prize. Appertization marked the birth of industrial canning technology.

    Preserves reached Spain in 1840 when a French sailboat was shipwrecked off Finisterre. Preserves were made in glass containers until the Englishman Peter Durand, began using tin cans, which gave the preserve greater resistance and protected it from the effects of light, thereby preventing the deterioration of the vitamin content.
