Starter Culture Cheese
Definition and Scope
Starter culture cheese refers to any cheese produced using specific bacterial cultures to initiate fermentation. These controlled microbial additions distinguish it from raw milk cheeses relying on ambient microflora. The category encompasses most industrially produced cheeses alongside many traditional varieties.
Starter cultures primarily consist of lactic acid bacteria like Lactococcus and Lactobacillus species. Their primary function is converting lactose into lactic acid, lowering the milk’s pH. This acidification is fundamental for curd formation, flavor development, and inhibiting spoilage organisms.
Production Process
The production begins by heating milk and inoculating it with a precise starter culture. The culture is allowed to ripen the milk for a set period, developing acidity. Temperature and time are carefully controlled to ensure optimal bacterial activity before rennet addition.
After coagulation, the curd is cut, cooked, and drained to expel whey. The specific handling of the curd, influenced by the starter’s acid production, determines the final cheese texture. Finally, the cheese is salted and aged, during which starter bacteria continue to influence flavor.
Sensory Profile
Starter cultures directly create the fundamental acidic and tangy notes characteristic of many cheeses. The specific strains used impart varying degrees of mild, buttery, or sharp flavors. A clean, predictable flavor profile is a hallmark of well-managed starter culture cheeses.
Beyond basic acidity, some cultures produce carbon dioxide, creating eyes or a supple texture. Others generate subtle flavor compounds like diacetyl for buttery notes. The texture ranges from soft and creamy to hard and granular, largely governed by the acid development during production.
Culinary Uses
Due to their consistent quality and flavor, these cheeses are widely used in cooking and food manufacturing. They provide reliable melting properties, making them ideal for sauces, pizzas, and grilled cheese sandwiches. Their predictable behavior is crucial for standardized food production.
Many starter culture cheeses are also enjoyed as table cheeses, paired with fruits, breads, and wines. Their balanced acidity can cut through rich foods, cleansing the palate. Grated hard varieties are frequently used as a finishing garnish for pasta and salads.
Regional Examples
Cheddar from England is a prime example, using specific Lactococcus strains for its sharp, tangy flavor. The cheddaring process relies heavily on the precise acid development from the starter. Its texture and flavor intensity are directly tied to the culture activity and aging time.
Gouda from the Netherlands utilizes thermophilic cultures that withstand higher cooking temperatures. This results in its characteristic sweet, caramel-like notes and smooth, pliable texture. Another example is Swiss Emmental, whose propionic bacteria create both its nutty flavor and distinctive holes.
