Prosciutto di Parma PDO: the primacy between science and terroir

Prosciutto di Parma, the history

Ham production in the Parma area has its roots in theRoman era. Already in the 3rd century BC, Cato the Censor in  De Agri Cultura documented the salting and drying of the pork leg, while Marcus Terentius Varro (116-27 BC) in  De Re Rustica referred to the  Parma inhabitants as particularly skilled in the production of salted hams. Between the 13th century and the 14th century, the Butchers' Guild was formed in Parma, dedicated to the processing of pork meats. The establishment of the Consortium of Prosciutto di Parma in 1963 established the protection of tradition and the certification of quality, while the recognition PDO (Protected Designation of Origin) arrived in 1996, protecting the product's identity in international markets.

Production and breeding area

According to the regulations, the production area of Prosciutto di Parma PDO includes the territory of province of Parma located south of the Via Emilia, at a distance not less than 5 kilometers from it, up to an altitude not exceeding 900 meters, bounded to the east by the course of the Enza river and to the west by the course of the Stirone stream. This terroir gives the product unique characteristics: fresh air currents from the Apennines promote the natural drying of the meat without the addition of preservatives or other additives.

I pigs destined for Prosciutto di Parma must be born, raised, and slaughtered exclusively in 11 Italian regions: Emilia-Romagna, Veneto, Friuli-Venezia Giulia, Lombardia, Piemonte, Molise, Umbria, Toscana, Marche, Abruzzo, and Lazio. The regulations establish that the pigs used must be over 9 months old and reach an average weight of at least 160 kg. Breeds registered in the Italian Genealogical Book (Large White, Landrace, and Duroc) are used, fed with cereals, vegetable proteins, and whey. The fresh thighs, afterslaughter, rest for 24 hours in cooling cells until reaching 0°C and, once trimmed, must have a weight over 10 kg.

Ingredients and production process

Parma Ham PDO stands out for its simplicity: the only ingredients allowed are pork meat and sea salt, without the addition of nitrites, nitrates or other preservatives nor any additives. The production process, handed down for centuries and strictly regulated, includes:

1. Salting. Sea salt is applied manually on the hams in a controlled amount, followed by a low temperature rest to promote even absorption;

2. Washing and drying. Excess salt is removed and the hams are dried with natural local air;

3. Aging. The specifications set a minimum aging of  14 months, during which the ham develops its distinctive organoleptic characteristics thanks to the natural action of the local microclimate. During this crucial phase an intense proteolysis, which is the breaking down of protein chains by endogenous enzymes of the pork muscle, resulting in the formation and release of free amino acids that contribute to the product's characteristic sweet flavor;

4. Quality control and branding. Each ham undergoes probing, an olfactory examination carried out with an instrument that penetrates the meat to evaluate its aromas. After passing the inspections of the Control Body, the five-pointed Ducal crown branding iron mark, a symbol of PDO authenticity, accompanied by the producer ham factory's initials, is applied.

The whole bone-in ham, at the moment of branding, must have a  minimum weight of 8.2 kg and maximum of 12.5 kg, rounded shape, a uniform cut color between pink and red interspersed with the white of the fatty parts, delicate and sweet flavor, characteristic aroma. The sea salt content (sodium chloride) must be a maximum of 6%.

Nutritional properties

According to the official data from CREA (Council for Agricultural Research and Economics Analysis) updated to 2023, 100 g of lean Parma Ham PDO – that is, deprived of visible fat parts – provide approximately:

• energy, 176 kcal

• proteins, 29.1 g

• total fats, 6.4 g

• salt, 5.1 g

• B vitamins, iron, potassium, zinc, selenium.

The presence of monounsaturated fatty acids, particularly oleic acid, characterizes the quality of lipids. The recommended portion is 50 g (about 3-4 slices), with occasional consumption frequency.

Distinction from other hams

Prosciutto di Parma PDO stands out from other Italian and foreign hams for unique characteristics:

• absence of additives. Only sea salt, no nitrites, nitrates, sugars, or preservatives. The red color is naturally maintained thanks to the proteolysis process.

• natural aging controlled by the terroir. The air and microclimate of the Parma area give the ham its sweet and unmistakable aroma, impossible to replicate elsewhere.
