Several steps are involved in producing sliced bacon. First each pork belly is skinned and any ragged edges trimmed. After curing with salt and nitrite, the pork bellies are heat processed. Mass-produced bacon is heat processed in large convection ovens. It is much faster to mass produce bacon using a convection oven (as little as 6 hours) than by traditional smoking (many days).
Bacon receives its smoke flavor from natural smoke obtained by smoldering wood chips or by spraying the bacon with a liquid smoke extract.
After heat processing and smoking, the bacon must be chilled to below 40 °F before it is sliced. The majority of bacon is sliced before packaging. Because of the added salt and nitrite, bacon is far less perishable than other raw meat products. Even so, the chilling is done quickly to prevent bacterial growth and promote its shelf-life.
There are two primary methods of curing bacon: pumping and dry curing. Although less frequently used, FSIS still receives label applications for immersion-cured bacon.
"Pumped" bacon has curing ingredients that are injected directly into the meat to speed up the curing process and add bulk. This type of mass-produced bacon is held for curing for 6 to 24 hours before being heated. If not properly drained, pumped bacon can exude white liquid during frying.
"Dry-cured" bacon has a premeasured amount of cure mixture applied or rubbed onto the bacon belly surfaces, completely covering them. Additional cure may be rubbed in over a number of days, but the amount of added sodium nitrite cannot exceed 200 parts per million (ppm). After the curing phase, the bacon may be left to hang for up to 2 weeks in order for the moisture to be drawn out. Less time is needed if it is going to be smoked. Because of the lengthy processing time and labor required, dry-cured bacon is more expensive than the more mass-produced, pumped bacon.
