Pasta filata
Stretched-curd cheeses — heated and pulled like taffy to develop fibrous, layered texture. Mozzarella, provolone, scamorza, caciocavallo, oaxaca.
Technical description
Curd is heated to about 75°C in hot water or whey, then stretched and folded by hand or machine until smooth and elastic. The stretching aligns protein fibers, producing the characteristic stringy, layered structure. Most pasta-filata cheeses can be eaten fresh (mozzarella) or aged (provolone). Aged varieties develop sharper, more piquant flavors as the protein structure breaks down over months. Fresh forms are sold in brine or water within hours; aged forms are hung from string and air-dried in cellars.
Aging parameters
Microbial environment
Thermophilic lactic starters (Streptococcus thermophilus, Lactobacillus delbrueckii subsp. bulgaricus). The high-temperature stretching effectively pasteurizes the curd surface, which is one reason pasta-filata cheeses were originally a way to preserve milk before refrigeration. Aged versions develop lipolytic activity from naturally occurring lipases (sometimes added kid-rennet lipase for piquancy).
History
Pasta-filata technique is documented in 12th-century southern Italian texts and likely older. The technique was the practical solution to using milk before refrigeration: stretching the curd at high temperature pasteurized the cheese surface and produced a product that lasted days to weeks in brine. Mozzarella di Bufala Campana traces to the introduction of water buffalo to southern Italy by Normans in the 12th century, with the Sele plain becoming the heartland. Oaxaca cheese (Quesillo) is one of the few non-European pasta-filata traditions — it was developed in 19th-century Oaxaca, Mexico, by Leobarda Castellanos Garcia, drawing on Italian techniques.
