Snack bars with high soy protein and isoflavone content for use in diets to control dyslipidaemia.

摘要

This study sought to develop a cereal bar product rich in isoflavones and soy proteins 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, a_w and darkness of the snack bars increased with storage time. A 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 (TG; --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 moderate beneficial effect on plasma lipid profiles, such as TG and HDL-c levels, without additional diet restrictions.
