The nutritional effect of diet containing decorticated sesame seed extracted with isopropanol (DSS-Iso) was evaluated on growth performance, food efficiency ratio, plasma and tissue lipid profile, plasma protein content, and erythrocyte membrane lipid profile of rats on a comparative basis with diets containing casein (control), soybean meal and decorticated sesame seed extracted with hexane (DSS-Hex). Rats fed a DSS-Iso-based diet showed body weight gain and food efficiency ratio similar to those of the control groups fed diets prepared with casein, soybean meal, and DSS-Hex. However, dietary proteins exerted a separate effect on plasma lipid concentrations of the rats. Rats fed a DSS-Iso-based diet showed significant decreases in plasma total cholesterol (p < 0.01), triglyceride (p < 0.01), and VLDL+LDL cholesterol (p < 0.01) concentrations in Comparison to the rats fed diet containing casein. No significant differences in plasma lipid concentrations were observed for the rats fed diets prepared with soybean meal, DSS-Hex, and DSS-Iso. Rats fed the different dietary proteins did not show much variation in plasma proteins, liver lipids, and erythrocyte membrane lipid concentrations, which suggests that DSS-Iso could be a suitable edible protein like casein or soybean meal.

Abstract: The dietary influence of sesame protein isolate (protein content 91.5%), produced from dehulled, defatted sesame meal, on blood and tissue lipid profile and lipid peroxidation has been assessed in normal and hypercholesterolemic rats. To evaluate their hypocholesterolemic and antioxidative activity in vivo, we fed 18% sesame protein isolate with or without 2% cholesterol in comparison with casein to rats for 28 d. We determined plasma total protein, total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triacylglycerol as well as susceptibility of plasma and erythrocyte membrane lipid to oxidation ex vivo. Liver tissue lipid, cholesterol, phospholipids, and lipid peroxidations were also determined. The total cholesterol, LDL-cholesterol and triacylglycerol levels were significantly reduced in the sesame protein isolate and isolate containing cholesterol group than the corresponding control casein groups. HDL-cholesterol level was also increased in sesame protein isolate (41%) and protein isolate containing cholesterol group (38%) than the corresponding control casein and casein containing cholesterol groups. There was 49% and 64% lowering of plasma lipid peroxidation as well as 36% and 56% lowering of lipoprotein oxidation susceptibility (LOS) in the 2 experimental groups (sesame protein isolate and isolate containing cholesterol group) than the corresponding control (casein and casein containing cholesterol) groups. There was significant lowering of erythrocyte membrane lipid peroxidation (68% and 63% lowering in sesame protein isolate and isolate containing cholesterol groups) and liver lipid peroxidation (61% and 76% lowering in the 2 experimental groups than the corresponding control casein groups). Therefore, our results indicate that sesame protein isolate decreases cholesterol concentration in plasma, increases HDL-cholesterol, and also decreases plasma and erythrocyte membrane lipid peroxidation with or without cholesterol fed diet in rats.Practical Application: Sesame protein isolate (SPI) can be produced from dehulled, defatted sesame meal. SPI consumption can reduce cardiovascular disease by reducing LDL cholesterol, triacylglycerol, and by increasing HDL cholesterol. As sesame is an important oil seed crop in various parts of the world, SPI can be utilized in various food formulation for its beneficial effect. © 2010 Institute of Food Technologists®.

Antihyperlipidemic Effect of Sesame (Sesamum indicum L.) Protein Isolate in Rats Fed a Normal and High Cholesterol Diet

A comparative evaluation of the nutritional value of palm oil, which was interesterified by lipozyme and by chemical catalysis, has been done with albino rats (Charles Foster strain). The two interesterified fats have identical coefficients of digestibility, and rats fed the two fats exhibit similar patterns of growth response and food efficiency ratio. The total lipid and total cholesterol levels in serum of rats of the two interesterified fats are nearly the same, but there is a significant difference in free cholesterol level. The lipozyme-catalyzed product creates a higher level of free cholesterol. Liver lipids of rats are identical in amount for the two groups, but the total cholesterol level of the lipozyme-catalyzed group is significantly less than the chemically catalyzed group. The positional distribution of fatty acids differs between the two interesterified products. The nutritional attributes of interesterified oils can vary depending on the specificity of the catalyst employed. © 1995 AOCS Press.
