Factors Affecting the Suitability of Boiled Pasta with Tomato Sauce for Eating

抄録

Pasta samples boiled for different times and mixed with tomato sauce were physically and chemically evaluated to determine the factors affecting the suitability of boiled pasta with tomato sauce for eating. Physical properties of the pasta boiled for the shortest time changed greatly when sauce was added. The texture of the pasta boiled for the longest time was soft, because the core lacked a non-gelatinized region. In a force–strain curve, the change in the force after the breaking point of the pasta boiled for the shortest time was the largest after sauce addition. The T₂ values and chlorine distribution of pasta samples showed that the amount of penetration of the sauce ingredients to the core of the pasta boiled for the shortest time was less than that of the pasta boiled for the longest time. These results suggest that small changes in the physical properties after the sauce addition, sufficient penetration of the sauce ingredients to the core, and the presence of a non-gelatinized region at the core are critical factors affecting the suitability of boiled pasta with tomato sauce for eating.
