Red kidney bean (Phaseolus vulgaris L.) instant porridge: Effect of isomalto-oligosaccharides and Fibercreme as sucrose replacement on lipid profile improvement in hypercholesterol-induced rats

The aim of the present study was to evaluate the effect of consumption pregelatinized kidney bean porridge with variation of sweetener including sucrose (BKM S), isomalto-oligosaccharides (BKM IMO) and Fibercreme (BKM FC) in hypercholesterolemia rats on the lipid profile, bile acid binding capacity, digesta cholesterol excretion and digesta characters including weight, water content and pH. The diets included standard diet for Negative Control rats (NC diet) and kidney bean porridge diets with different sweeteners: sucrose (BKM S diet), IMO (BKM IMO diet) and fibercreme (BKM FC diet), respectively. Red kidney bean instant porridge substituted 30 of total calories of the diets. All of the diets were formulated based on AIN 93M standard and were fed for 28 days. The result showed that BKM IMO and BKM FC diets improve lipid profile of rats by reducing total cholesterol, LDL cholesterol and triglycerides and increasing HDL cholesterol. In addition, both diets increased cholesterol excretion. In vitro measurement of bile acid binding capacity showed that BKM IMO and BKM FC have a higher binding capacity than BKM S. It can be argued that increasing of cholesterol excretion and bile acids binding capacity of these diets are responsible for the improving of the lipid profile. BKM IMO and BKM FC have higher digesta weight and water content but lower pH. It is concluded that substitution of sucrose as sweetener with isomalto-oligosaccharides and Fibercreme in the formulation of pregelatinized kidney bean porridge improve the beneficial health effect of kidney bean porridge.
