American Style Pepperoni vs. Old World Style Pepperoni

Pepperoni sausages are available in two major types: the American pepperoni, which is also known as the regular pepperoni, and the old world pepperoni, which is the traditional pepperoni. However, the two share a lot of similarities, but still, there are differences:

American pepperoni style has emerged along with the industrial era of food production. American pepperoni uses an artificial casing that produces straight and evenly thick sticks that can be easily sliced. It’s not reddish but slightly orange, while Old world pepperoni style uses natural casing made of sheep gut. Old world pepperoni becomes curly since it uses a natural casing and varies in thickness. It is dark red in color but spicy.

American-style pepperoni casing is cheaper and does not spiral, making for a more even product that is easy to slice. Nevertheless, they grow no mold coating making American-style pepperoni unable to develop old world pepperoni flavor and characteristics, while Old world style pepperoni natural casing stretches well and spirals during filling. Instead, it develops a layer of flavor mold whereby the enzymes act on the meat to improve flavor and texture.

Another feature that distinguishes American pepperoni is its simple lactic acid-producing fermentative culture, while Old world pepperoni is the traditional mixed bacterial culture. In addition, it includes a second type of bacteria known as CNC (coagulase-negative cocci), which is missing in American pepperoni.

Why Does Pepperoni Curl?

Pepperoni curls up because the natural casing shrinks when cooked. It creates a discrete lip that cooks quicker than the base. The reasons why pepperoni curls are:

Thickness: if the pepperoni slices are thicker, it determines the heating rate between the pepperoni’s top slice and bottom slice. If the pepperoni’s top slice cooks faster than the bottom, it has the tendency to shrink more which makes the pepperoni sausage curly.

Casing: casing also makes pepperoni curly. Pepperoni sausage sticks are made by stuffing meat products or mixture into casing. It can be either artificial or natural casing. Old world pepperoni has a natural casing that shrinks up when cooked or baked.

How Pepperoni is Made

Pepperoni is made of hybrid meat with its different processes. First, the finely ground pork and beef are mixed well. Some people use sodium nitrate in the mix as a curing agent. Air drying is an important part of getting the texture. It is the process of adding salt and nitrate to meat. The sodium refrains the meat from growing microorganisms, and the nitrate gives it a red or brownish color.

Next, the meat is injected with lactic acid bacteria, which is usually used to make cheese and yogurt. The lactic acid bacteria allows the meat to become better preserved. Finally, the meat is fermented, and the fermentation converts the carbs of the meat into alcohol. It is stored in the fridge, then dried in the air.

However, some producers use sugar to bring more flavor and color to the sausages. To increase the smoked flavor, a casing is essential to absorb the smoke. If the pepperoni is intended to use as pizza toppings, it is sliced and then packaged.
