The invention provides soybean peptide and soybean oligopeptide with a blood fat reducing effect as well as a preparation method and application of the soybean peptide and the soybean oligopeptide, and relates to the technical field of active peptide. According to the invention, the soy protein isolate is used as a raw material and is treated by a special process, so that sensitization protein and anti-nutritional factors in the soy protein can be removed, and the utilization rate and the action effect of the soy protein are remarkably improved. Two oligopeptides with high blood fat reducing activity are separated, purified and identified from the soybean peptide, and the amino acid sequences are shown as SEQ ID NO.1 and SEQ ID NO.2. The embodiment verifies that the oligopeptides have a remarkable blood fat reducing effect. 本发明提供了一种具有降血脂作用的大豆肽、大豆寡肽及其制备方法和应用，涉及活性肽技术领域。本发明以大豆分离蛋白为原料，经特殊工艺进行处理，可去除大豆蛋白中的致敏蛋白和抗营养因子，从而显著提高大豆蛋白的利用率和作用效果。本发明还从大豆肽中分离纯化和鉴定出两条具有高将血脂活性的寡肽，氨基酸序列如SEQ ID NO.1和SEQ ID NO.2所示，经实施例验证，其具有显著的降血脂效
