The quality of a pasta product is evaluated by dry appearance and cooked texture. ‘Good Pasta’ is defined as having uniform amber colour with an absence of black, brown or white spots, a smooth surface free of streaks or cracks, and a texture that when cooked is neither chewy nor mushy but ‘al dente’. Three key factors determine success or failure in pasta production: raw materials, processing technology and the presence of skilled employees throughout the manufacturing process…

Pasta is a common source of carbohydrates in our diet today. Production and consumption of pasta products vary depending on the region of the world and culinary traditions within a society. Italy ranks as the highest consumer of pasta in the world at nearly 26 kilograms per capita, which is nearly double its next closest competitor, Venezuela1.
Most pasta products on the market, outside of instant noodles, are made from durum wheat semolina, and are processed via low temp – erature extrusion (less than 50°C)2. After extrusion and drying, these traditional pasta products have very low starch gelatinisation levels (less than 50 per cent) and must be cooked before serving. These products can also be treated to produce precooked pasta. This is accomplished after the conventional extrusion press process by a cooking stage in which the formed pasta is subjected to a steam or water bath followed by drying.
Another way to make a fully cooked pasta product without additional treatment is with extrusion cooking3. Typically, a twin screw extruder is used to wet the dough and cook and extrude it under high pressures and temperatures ranging from 90 to 110°C. This results in pasta products that can be rehydrated in three to eight minutes and they resemble the texture of those products made via a conventional process.

Pasta, the Italian food par excellence, is one of the most interesting products obtained from wheat. Dried pasta has a long shelf-life before being cooked, thanks to its low water content and highly compact texture. Its macromolecules have exceptional hydrating capacities which enable it to increase its weight two-fold and acquire a palatable structure when cooked in boiling water while maintaining a high structural compactness. This property allows starch to be slowly digested, thus ensuring the product a low Glycemix Index despite its high carbohydrate content1. Pasta can then be combined in many different kinds of sauces to suit every taste and to remedy the deficiency of wheat regarding some essential amino-acids.

Pasta is apparently a very simple food, with one ingredient: semolina of durum wheat and one reactant: water. In its native state, the ingredient has two main constituents, which are proteins and starch. The reactant, together with mechanical and thermal energy, is necessary to modify their structure to obtain the final configuration. In Figure 1, a dried spaghetti section, the starch granules and the protein net formed are clearly recognisable.

Traditional pasta is made from semolina and water. Its simplicity in composition has made it an inexpensive meal that is familiar to many people worldwide. The milling of durum wheat into semolina removes the bran and germ which are rich in dietary fibre, vitamins and minerals. To offset the loss of these healthful components, many countries require pasta to be fortified with thiamine, niacin, riboflavin, folic acid and ferrous sulphate.
Pasta has ancient roots that go back approximately 7,000 years to when humankind abandoned his nomadic lifestyle, started to cultivate the land and learned how to process grain. For many years, Marco Polo was credited with introducing pasta to Italy after his voyages in China, but several written documents deny this. In one of them, dated 1154, the Arab geographer Al-Idrin mentions ‘food made of strings’ called ‘triyah’ which was produced in Palermo. It is therefore thought that pasta, intended as ‘maccheroni’, actually originated in Sicily, around Trabia, near Palermo.
Every year, in various educational institutions across the globe, students compete to design and build bridges made from spaghetti strands. In most competitions, the winner is that student team whose bridge can sustain the highest load (Johns Hopkins, 2005). Clearly some elaborate design work goes into the creation of these food engineering masterpieces (Figure 1).
However, bridge building is not the only use for pasta! Many nutritious and appetising dishes can be made from various pasta structures, such as spaghetti, lasagna, gnocchetti, manicotti, capellini, fettuccine, etc. For all pasta products, the preferred primary ingredient is semolina – coarse flour made from durum wheat. Pasta can be made from common wheat (bread-making and confectionery wheat), but is perceived as inferior to durum wheat pasta and, in some countries, legislation prohibits the addition of common wheat ingredients beyond a specified small percentage in pasta. Durum wheat was originally cultivated in the Mediterranean where, today, semolina is also used for the manufacture of specialty breads and products such as couscous, bulgar and frekeh. In recent years the proportion of durum wheat used for bread-making has been increasing.
