This study aimed at exploring the effect of the added components as nucleuses on recrystallization of rice starches. To analyze the changes of retrograded starch crystal, V-type seed crystal was added into the rice starch paste during cooling. The fitting data showed that crystal cell sizes for a and b were, relatively, shorter than c axis in the orthorhombic unit cell. For starch system stored at 4 ℃, part of the crystal seed might work as the nuclei, and the recrystallization rate was increased. The arrangement of the starch molecular segments approaching the seed was affected by the arrangement of the molecular segments on the seed growth surface, which made the induced starch cells more similar to V-type seed cells. These findings suggest that the recrystallization controled of starch crystals when lipids existed in starch system, and provided a theoretical basis for the application of lipids in the preparation of slow digestion starch and other nutritional starches.
