Hot dogs are a processed meat product made by mixing chopped meat with various curing ingredients, flavorants, and colorants. The meat is then stuffed in casings, cooked, removed from the casing, and put in the final package. Although the technology for hot dog making was developed thousands of years ago, these meat products continue to be a popular summertime food. In fact, in America alone over 16 billion hot dogs are consumed each year. The primary ingredient in hot dogs is the meat.

While pork is most often used, other types may be used such as beef, chicken or turkey. Sometimes variety meats like livers are used however, the hot dog producers must clearly label the product with the statement "with variety meats" or "with meat by-products."

Myoglobin and hemoglobin proteins create the natural color of the meat. Fats in the meat give the characteristic flavor. READ MORE
