Food preservation in hermetically sealed containers by the application of heat. Originated by Nicolas Appert in France 1809 with glass containers, it was developed by Peter Durand in England 1810 with cans made of sheet steel thinly coated with tin to delay corrosion. Cans for beer and soft drinks are now generally made of aluminum.
Canneries were established in the US before 1820, but the US canning industry began to grow considerably in the 1870s when the manufacture of cans was mechanized and factory methods of processing were used. The quality and taste of early canned food was frequently dubious but by the end of the 19th century, scientific research made greater understanding possible of the food-preserving process, and standards improved. More than half the aluminum cans used in the US are now recycled.
