Swelled cornstarch granules incubated at different incubation temperatures was prepared as a complexation matrix to encapsulate lutein. Increasing incubation temperature (55–70 °C) induced the gelatinization of cornstarch, resulting in enhancement of swelling power (1.67–6.26 g/g) and lutein content (0.78–4.86 mg/g). A decreased (double helix of amylopectin) and an increased (single helix of V-amylose) enthalpy change were associated with the increased incubation temperature. The retention index of lutein in the composites incubated at 65 °C and 70 °C could achieve 76% after 21 days of storage. Less than 30% of lutein in the composites was released after incubating for 120 min under stomach conditions. Fast lutein release was observed during the first 20 min intestinal digestion, consistent with starch hydrolysis data. This study opens a promising pathway for swelled cornstarch granules as delivery carriers of bioactive ingredients, which are of vital importance for their potential use in the sensitive food supplement.

将在不同温育温度下温育的溶胀的玉米淀粉颗粒制备为包封叶黄素的络合基质。升高的孵化温度（55–70°C）导致玉米淀粉糊化，从而导致溶胀力（1.67–6.26 g / g）和叶黄素含量（0.78–4.86 mg / g）提高。焓变的降低（支链淀粉的双螺旋）和增加（V-直链淀粉的单螺旋）与孵育温度的升高有关。叶黄素在65°C和70°C孵育的复合物中的保留指数在储存21天后可达到76％。在胃条件下孵育120分钟后，复合物中不到30％的叶黄素释放出来。在最初20分钟的肠内消化过程中观察到叶黄素快速释放，与淀粉水解数据一致。
