The objective was to develop a cereal bar product rich in isoflavones and soy protein to be used in diets for controlling dyslipidaemia. A soy snack bar with 39.88 g/100 g dietary fibre, 34.25 g/100 g protein, 100.39 mg/100 g isoflavones and 245.47 kcal/100 g was produced. The shelf life of the product was tested over a period of 6 months. The hardness, water activity and darkness of the snack bars increased with storage time. Clinical trial was carried out to evaluate the effectiveness of the soy snack bar on the lipid profiles of 22 dyslipidaemic subjects for a period of 45 days. There was a decrease in levels of triglycerides (TGs) (- 20%) and an increase in high-density lipoprotein cholesterol (HDL-c) (+8%) comparing with baseline values. Therefore, relatively high intakes of soy protein and isoflavones in moderately hypercholesterolaemic subjects (>200 mg/dl) may have a moderately beneficial effect on plasma lipid profiles, as TG and HDL-c levels, without additional diet restrictions.
目的是开发一种富含异黄酮和大豆蛋白的谷物棒产品，用于控制血脂异常的饮食。生产出一种膳食纤维含量为 39.88g/100g、蛋白质含量为 34.25g/100g、异黄酮含量为 100.39mg/100g、热量为 245.47kcal/100g 的大豆零食棒。对产品的保质期进行了为期 6 个月的测试。随着储存时间的延长，零食棒的硬度、水分活度和颜色变暗。进行了临床试验，以评估大豆零食棒对 22 名血脂异常受试者血脂谱的有效性，为期 45 天。与基线值相比，甘油三酯（TGs）水平降低了（-20%），高密度脂蛋白胆固醇（HDL-c）水平升高了（+8%）。因此，在中度高胆固醇血症患者（>200mg/dl）中相对较高地摄入大豆蛋白和异黄酮可能对血浆脂质谱有适度的有益影响，如 TG 和 HDL-c 水平，而无需额外的饮食限制。
