Abstract

The objective of this study was to analyze the effect of carbohydrate fraction of hyacinth bean (Lablab purpureus (L.) sweet ) diet on lipid profile and peroxydation value of the blood serum and liver of rats. Fifteen male wistar strain rats were divided into three diet groups of live animals. The first group was positive control group with standard diet. The third group was given carbohydrate fraction of hyacinth bean and 1% pure cholesterol. The experiment was conducted for 75 days. The total cholesterol levels in positive, negative control, and that in the hyacinth treated group were 204.0, 74,8, and 99.8 mg/dl. The LDL levels in the control, negative control group, the hyacinth treated group were 153.0, 20.6 and 45.9 mg/dl. Triglyceride levels in the positive control, negative control, and the hyacinth treated group were 121.4, 137.7, and 114.8 mg/dl. The atherogenic index in the positive control, negative control, and the hyacinth treated group were 6.9, 1.9 and 2.5 point. The total cholesterol and LDL levels in positive control, negative control, and the hyacinth treated group underwent hypercholesterolemia effect. Malonaldehyde content of the blood serum in positive control, negative control, and the treated group were 0.54, 0.48, and 0.31 µmol/ml. Malonaldehyde content of liver organ in positive control group, negative control group, and the hyacinth treated group were 66.9, 36.4 and 73.4 nmol/g. Malonaldehyde content of blood serum in hyacinth treated group was significantly lower than that in the positive and negative control group. These result showed that the hyacinth group decreased free radical in the blood serum. On the other hand, the malonaldehyde content of the liver in all treatment showed no significant differences. Keywords : Carbohydrate fraction, Hyacinth bean, Lipid profile, Peroxydation.

Abstract

An emergency food based biscuit product was formulated by utilizing composite flour from white sweet potatoes, germinated soybeans, and germinated mung beans. This product was designed to meet high protein and energy wich contain protein as minimum as 12% and 50% carbohydrate. Sweet potatoes, germinated soybeans, and germinated mung beans flour were obtained by using drum dryer. The flour characteristics determination showed that there were positive corelation between bulk density and wettability, and had negative corelation with stack angle. The bulk density number of sweet potatoes, germinated soybeans, and germinated mung beans flour were 0.56, 0.38, 0.45 g/m; compact density 0.63, 0.54, and 0.56 g/ml; whiteness degree 49.77, 29.82 and 34.41%; stack angle 30.56, 41.77 and 31.16 degree; wettability 1.104, 345, 20 second; and dispersibility 1.98, 1.06 and 0.70%. Wheat flour could be substituted by sweet potatoes flour as much as 80%. The range utilization of germinated soybeans and germinated mung beans flour were 12-28 % which combined with 25-44% sweet potatoes flour. The nutritional composition of high energy and protein biscuit were within average range of protein 12.34%, fat 24.56%, carbohydrate 60.65 %, and also total dietary fiber 15.01%. The result of organoleptic test showed that high energy and protein biscuit was accepted by consument, so that its very potential to ben as alternative food. Key words : composite flour, bulk density, compact density, wettability, dispersibility, biscuit

Abstract

Extracts of ginger contain a great number of substances having antoxidant activity. This reaserch was conducted to study the effect of ginger on malonaldehyde (MDA) as indicator of free radical and vitamin E as one of the nutrient antioxidants. Healthy student subjects were divided into treated (n=12) and control group (n=12). Treated group was suplemented with ginger drink for 30 days.At the beginning and the end of intervention, both treatment and control groups were subjected to physical health examination and their peripheral blood were with drawn for analysis of MDA (malonaldehyde) and vitamin E in plasma. Individual data from all groups revealed that treated group has significant decrease of MDA and increase of vitamin E (p

Abstract

The hypoglycemic response to Lablab nonprotein fraction (NPK) was evaluated in alloxan-induced diabetic rats. The objectives of this research were to evaluate the effect of Lablab nonprotein fraction diet on the blood  glucose concentration and the lipid  peroxide  level of alloxan-induced diabetic rats.  Two months old male Sprague Dawley rats were divided into 4 groups, each group contained of 5 rats. Three groups were diabetic rats  induced by alloxan injection (110 mg/kg of body weight by intra-pheritonial injection) while one group was a control,normal rat. The experiment groups were (1) normal (group I), (2) diabetic (group II), (3) diabetic+cholesteol 0.5% (control group, group III), and (4) diabetic+cholesterol 0.5% + lablab NPK (group IV). The concentration of rat’s blood glucose were periodically measured during diet intervenion (day 0,14,27, and 42). The Lipid peroxide was evaluated as the concentration of malonaldehyde (MDA) both in serum and liver of the rats by Thiobarbituric Acid Reactivity Test methode. The result demonstrated that after 42 days of intervention, the Lablab nonprotein diet decreased the blood  glucose  concentrations from 444.00 + 143.00 mg/dl to 310.50 +111.40 mg/dl (30%), while control group has  decreased the blood glucose concentration from 458.00 +164.99 mg/dl to 455.33 + 81.95 mg/dl (0.6%). Lablab nonprotein diet significantly (P<0.05) reduced the concentration of blood  glucose as compared to the control group. However, Lablab nonprotein fraction diet did not give a significant diferrence on the level of serum MDA and liver MDA as compared to the control group.
