In the early 1900s, food manufacturers began to produce hot dogs in larger quantities. At this time, food emulsifiers were often added to preserve hot dogs further as they were packaged and shipped to increasingly more distant places. In fact, in the early 1900s, food manufacturers created a somewhat negative image of hot dogs that still affects their reputation. During this time, some manufacturers began to add sawdust or applied other shortcuts, including mixing meats with different animals and sometimes even rotting meat.
