摘　　要：旨在为葵花籽仁的分级应用提供理论依据,以葵花籽为原料,通过多级精分设备将葵花籽进行脱壳、分级,分为小(≤3 mm)、中(3~4 mm)、大(>4 mm)3种粒径等级的葵花籽仁,分别对葵花籽仁组成进行比较分析。结果表明,各粒径葵花籽仁含油量均超过60%,油中不饱和脂肪酸相对含量超过85%,且小粒径葵花籽仁含油量及油中亚油酸相对含量最高。各粒径葵花籽仁粗蛋白质含量为44.93%~53.33%,大粒径葵花籽仁粗蛋白质及氨基酸含量最高。3种粒径葵花籽仁绿原酸总量为26314.93~28095.98 ng/mg,中粒径葵花籽仁总绿原酸总量最高。3种粒径葵花籽仁总淀粉含量为0.067%~0.090%,小粒径葵花籽仁总淀粉含量最高;3种粒径葵花籽仁抗性淀粉含量为0.019%~0.032%,中粒径葵花籽仁抗性淀粉含量最高。In order to provide a theoretical basis for the application of sunflower seed kernels grading, sunflower seed were used as raw material, and sunflower seeds were hulled and graded by multi-stage fine separation system to three particle sizes of small(≤3 mm), medium(3-4 mm) and large(>4 mm), and the composition of sunflower seed kernels was compared and analyzed, respectively.The results showed that the oil content of sunflower seed kernels of all particle sizes was more than 60%, the relative content of unsaturated fatty acids in oil was more than 85%, and the sunflower seed kernels with small particle size had the highest oil content and relative content of linoleic acid in oil. The content of crude protein of sunflower seed kernels was 44.93%-53.33%, and the sunflower seed kernels with large particle size had the highest crude protein and amino acids content. The content of chlorogenic acid of sunflower seed kernels was 26 314.93-28 095.98 ng/mg, and the sunflower seed kernels with medium particle size had the highest chlorogenic acid content. The total starch content of sunflower seed kernels was 0.067%-0.090%, with the highest total starch content in the small particle size sunflower seed kernels. The content of resistant starch was 0.019%-0.032%, and the sunflower seed kernels with medium particle size had the highest resistant starch content.
