You may have asked yourself while eating this popular delicacy: how are hotdogs made?
Hotdogs are made of specially selected meat trimmings of beef and/or pork that are cut and ground into small pieces and then placed in a mixer.
High speed, stainless steel choppers combine the meat, spices, ice chips and curing ingredients into an emulsion or batter. The mixture is then placed into an automatic stuffer/linker machine, where it flows into casings. Then they are linked into long strands of hot dogs and cooked under controlled temperature and humidity conditions.
Afterwards, the hot dogs are showered in cool water and later placed into the packaging equipment.
In the United States, the process is carefully regulated and inspected by the U.S. Department of Agriculture.
