Spam shares its name with the unwanted annoying emails you usually receive.

Spam is a canned meat product that hit the shelves in 1937. The original canned pork product, Spam, was manufactured by Hormel Foods Corporation in Austin Minnesota. As the end of the Great Depression came towards its end there was a huge need for meat products that weren’t expensive. This where Spam came in, satisfying this need.

During World War II, Spam cemented its place in the culinary world because of its ability to stay for long periods in storage without going bad. By then about 40 million spam cans had been sold. Hormel Foods sent 15 million cans of the product each week throughout the war to feed the American soldiers together with the allied troops.

World leaders like Margaret Thatcher and Eisenhower highly praised the product’s effectiveness during the time of war. By 1959, Hormel Foods had manufactured its billionth can. Ever since there are 15 different varieties of spam that are being produced in 43 different countries.

Ingredients

Spam is made up of six ingredients which include pork with added ham meat, salt, potato starch, water, sodium nitrite, and sugar. Approximately 90% of Spam is pork from pig’s shoulders, with 10% coming from the pig’s ham.

Salt is included in the ingredient to add flavor and act as a preservative. Water is meant to hold the ingredients together. Sugar is added to enrichen the flavor.

Sodium nitrite helps to retain its freshness. It gives Spam a bright pink color while acting as a preservative at the same time by preventing the growth of bacteria. However, this is the ingredient that might make you raise your eyebrows.

The manufacturing process starts with the pig pieces arriving at the processing plant. The pork is removed from the bone using machines while the ham is trimmed by hand. The meat is ground up and then mixed with the rest of the ingredients for 20 minutes in airtight mixers.

It is then piped onto a conveyor belt and pumped into the cans which get vacuum-sealed. The cans are taken into a cooker which heats them to kill any bacteria. They are then slowly cooled for 3 hours, labeled, and packed for transportation.
