    Abstract:
    In this study, two different lupin flour obtained from debittered seeds by ultrasound application and traditional method (at 0-20% ratios), and resistant starch type 4 (RS4) (at 0-10% ratios) were used in pasta preparation to improve its nutritional quality. Experiments conducted at (2 × 4 × 3) × 2 factorial design. Use of ultrasonicated lupin flour in pasta revealed similar chemical, thermal and sensory properties to lupin flour debittered by traditional method. The replacement of semolina with lupin flour enhanced protein, dietary fiber and mineral content of pasta. Addition of lupin flour or RS4 increased cooking loss and firmness values of pasta. Pasta containing 20% lupin flour and 10% RS4 had higher gelatinization onset temperature values, and lower enthalpy than 100% semolina pasta. Use of RS4 in pasta reduced in vitro glycemic index without having any adverse effect on the sensory properties. The current findings indicate that it is possible to produce pasta with acceptable cooking quality and sensory properties and improved nutritional quality by adding 15% ultrasonicated lupin flour with 5-10% RS4.
