History of canmaking (steel packaging) goes back much further than one can estimate. Have You Ever Heard The Name Of French Cook Nicolas Appert? If history of food processing was written, you would definitely know this name. The reason being that; Nicolas Appert was the first person to think to conserve food stuff. When Appert started to use this method, which was a revolution in food processing sector, calendars were showing 1700s. The basic principal of this method, developed by the French cook Appert, is that, food filled, eliminating air contact, could be sterilized using proper heat treatment. Main objective of Appert was to conserve the food products for long time, without loosing their nourishing properties, and values. And he was successful. In the light of this invention of Mr. Appert, sterilized canned food has been introduced. Can (steel packaging) is still be one of the best food conserving tool. Steel packaging had a rapid developing process up to now and became an important and independent sector. Today, cans are manufactured in large scale plants, with computer controlled advanced technology based machines. The usage of cans, is preferred also in many other sectors (such as chemicals, lubricating oils, textile etc.) increasing steadily every day. Today, approximately 80 billion cans are being manufactured yearly in the whole world.
