The purpose of this work was to compare in vitro and in vivo starch digestibility of a typical Italian variety of rice (Fino Ribe) industrially processed in three different ways (polished, parboiled or quick-cooking parboiled). Portions of the three samples were digested in vitro with pepsin and pancreatic α-amylase. Percentages of starch digested were significantly (P < 0·05) lower in parboiled and quick-cooking parboiled rices than in polished rice. Completeness of starch digestion in vivo and glycemic response were evaluated using the breath-H2 and the glycemic index techniques in nine healthy volunteers. Both the processed rices had a lower (P < 0·05) glycemic index than polished rice but no evidence of higher malabsorbed starch.
