摘要
Some people with Non-Coeliac Gluten (or Wheat) Sensitivity (NCGS) declare that they can consume peasant pasta without the usual inconvenience they experience after eating industrial pasta. The main differences between peasant and industrial pasta lie in the varieties used (old vs. modern), and the production chain : (grain milling, semolina hydration and mixing, extrusion or lamination, drying and packaging). Yet, the varieties, the material and the method used by the peasants and by the industrial sector to make pasta differ at each stage. The impact of each of these stages was analyzed on protein quantity and quality from semolina to cooked pasta. Grown in the same conditions, the old variety (cv. Bidi 17) used by farmers contained much more protein than the modern variety (cv. Anvergur) recommended by industry and its pasta was better-digested in-vitro. Focusing on cooked pasta, milling had a great impact on not easily soluble proteins (DTE-soluble proteins): pasta made from stone-milled grains (peasant method) had less DTE-soluble proteins than pasta made from roller-milled grains (industrial method) and a higher amount of in-vitro digested proteins. The mixing and extrusion step mainly affected the easily soluble proteins (SDS-soluble proteins). The amount of such proteins was greater for farmer cooked pasta (non-monitored extrusion) than for industrial ones (monitored extrusion). Concerning the drying step, the proportion of SDS-soluble proteins was higher for the pasta dried at low temperature (peasant method), compared to high temperature (industrial method). Thus, the observation that peasant cooked pasta would be more digestible than industrial pasta seems to be due mainly to variety (61%), to a lesser extent to grinding on a stone-mill (22%) and extrusion on non-monitored conditions (16%) and finally a little (1%) to drying at low temperature and therefore longer.
