The effect of ethephon spray on leaves at pre-harvest stage to accelerate the ripening process of capsules and sesame defoliation was studied. Sesame plant was treated with ethephon at concentrations of 0, 50, 100, 200, 300, 400 and 500 ppm when the capsules on plant began to mature, the seeds turned black. The results showed that ethephon treatment caused yellowing of leaves, accelerated defoliation and the growth time of sesame plants was shortened from 5 to 6 days compared to the control sample. In addition, the ethephon concentration of 50 and 100 ppm caused yellowing of leaves with chlorophyll index measured at 3 days after treatment was 13.5 and 12.7, respectively. At ethephone concentration of 200-500 ppm caused complete yellowing and defoliation of leaves in 3 days after treatment. The leaves of control sample were still green and had chlorophyll index of 22.2. Treatment of ethephon with concentrations of 50-300 ppm did not reduce the yield and lipid content in the seeds compared to the control sample, but from 400 ppm or more caused cracking of capsules, reducing yield and lipid content in the seeds. Ethephon treatment did not affect the number of capsules/plant, number of seeds/capsule, weight of 1000 seeds, protein content and seed color.

The need for a preventive agent against dementia led us to screen natural plant resources. Among the herbs and spices tested, sesame seed prepared from Sesamum indicum seeds showed potent β-secretase inhibitory activity. The active principles were determined to be sesamin and sesamolin, typical lignans in S. indicum. The IC50 values of sesamin and sesamolin were 257 and 140 μM, respectively. These compounds were investigated in a preliminary absorption experiment. After oral administration, these compounds were detected in an intact form in the brain and serum. These results suggest that consumption of sesame seeds may prevent dementia by sesamin and sesamolin, the constituents in sesame seeds.

Abstract This study evaluates the application of Cr(VI) adsorption from the prepared synthetic solution by black sesame (Sesamum indicum L.) seed pulp (BSSP) and chitosan (Cts)-coated black sesame seed pulp beads (Cts-BSSP). BSSP and Cts-BSSP were used as an adsorbent without any chemical or physical treatment to remove Cr(VI) from an aqueous medium. The results indicated that the Cr(VI) removal was pH-dependent and reached an optimum at pH 2.0. It has been observed that the percentage of adsorption increased from 62% to 95% when the amount of Cts-BSSP increased from 0.0125 g to 0.0250 g. The required adsorbent amount for the maximum removal was 0.05 g and 0.1 g for Cst-BSSP and BSSP, respectively. The contact time for the adsorption was 120 min and 90 min for BSSP and Cst-BSSP, respectively. Scanning electron microscopy and Fourier transform infrared spectroscopy were used to explore the possible adsorption mechanism for Cr(VI). The equilibrium data for the BSSP and Cts-BSSP were used with the Langmuir and Freundlich adsorption isotherm models to assess the adsorption capacity and relevant mechanism. The adsorption capacity of the Cts-BSSP for Cr(VI) is relatively high compared to BSSP. The monolayer maximum adsorption capacities for Cr(VI) ions were 31.44 and 18.32 mg/g for Cts-BSSP and BSSP, respectively.

Some physical and aerodynamic properties of two varieties of sesame seeds (Yandev -55 and E8) were determined at varied moisture content levels. These properties are factors in the design and selection of sesame seed-cleaning machines. For the Yandev-55 and E8 varieties, major diameters ranged from 2.8 mm to 3.3 mm and 3.4 mm to 3.8 mm, intermediate diameters ranged from 1.8 mm to 2.1 mm and 2.2 mm to 2.5 mm, and minor diameters ranged from 0.7 mm to 0.9 mm and 0.6 to 0.9 mm, respectively. Their geometric means ranged from 1.5 to 1.8 mm and 1.7 to 2.0 mm, their spheroids ranged from 0.5 to 0.6 and 0.5 to 0.6, and their frontal areas ranged from 1.8 to 2.6 and 2.2 to 3.2, respectively. The terminal velocities of Yandev-55 were 2.9, 3.6, 4.7 and 5.4, while the terminal velocities of E8 were 3.4, 4.12, 5.1 and 6.3 at a moisture content level of 8.0, 10.3, 15.9 and 21.2 % (w.b.), respectively. The drag coefficients were in the range of 0.4 to 2.7 while Reynolds number varied from 2775.0 to 7840.7. The terminal velocities of the associated materials within the seeds were 1.5, 2.3, 3.1, and 3.6 at a moisture content level of 8.0, 10.3, 15.9 and 21.2%, respectively. The studied properties significantly varied with the varieties of sesame seeds. Also, the effects of moisture content are non negligible.

The effect(s) of sesame (Sesamum Indicum L) seed oil on the growth rate, performance and some biochemical parameters in adult albino (Wister) rats maintained on a high fat diet was examined. Adult rats maintained on a high fat diet were intragastrically fed 10mg/ml of sesame seed oil suspended in normal saline, daily for 60 days. Two other groups maintained on the high fat diet only (High fat diet control) and the normal diet (Normal diet control) were included. Water and diet were provided ad libitum. The rats were weighed weekly, while feed supply and left-overs were recorded daily. At 60 days, all animals were killed by decapitation. Blood and liver samples were taken for biochemical analyses. Feeding high fat diet significantly (P<0.05) increased the final body weight, liver and kidney weights of the rats compared to those on normal diet. Administration of sesame seed oil along with high fat diet further increased (P <0.05) the final rat body weight while decrease (P<0.05) was observed in the liver weight and a significant (P 0.05) decrease in the kidney weight was observed compared to the high fat diet fed rats. Biochemical profile shows significantly (P<0.01) higher levels of plasma proteins and globulins in the normal diet-fed rats compared to the high fat-diet-fed rats. Administration of sesame seed oil along with high fat diet significantly (P<0.01) increased the plasma glucose, total proteins, globulins and uric acid concentrations compared to the high fat diet fed rats. Significantly (P<0.01) higher glucose and uric acid levels and a significantly (P<0.01) lower globulin levels were observed in the sesame seed oil group compared to the normal diet control group. The plasma albumin concentration did not differ significantly among the groups.

The research was carried out to ascertain the feasibility of preparing paneer from milk blend containing low pressure homogenized milk to avail the benefits rendered by homogenization. Standardized milk was subjected to two-stage homogenization (4.90 and 0.98 MPa respectively) and then blended with unhomogenized standardized milk in three proportions (i.e. 3:7, 4:6 and 1:1, w/w). It was necessary to add calcium chloride to the milk blend to improve the firmness of resultant paneer. The experimental paneer samples obtained from ‘milk blend’ containing homogenized milk, as well as control sample (only from unhomogenized milk) were studied for their proximate composition, physico-chemical characteristics, textural properties and sensory quality. Paneer obtained from milk blend (homogenized:unhomogenized; 4:6 w/w) resulted in greater fat recovery and moisture content culminating in significantly higher yield compared to control paneer (CP). The hardness of paneer obtained from blended milks was lower, but the springiness of BMP3:7 sample was greater than that of CP. The total sensory score of experimental paneer BMP4:6 was similar to the score associated with CP, but greater than the scores associated with paneer samples BMP3:7 and BMP1:1. Blending of homogenized (low pressure) milk with unhomogenized milk in 4:6 proportion helped in obtaining paneer with superior fat recovery and yield compared to use of unhomogenized milk, without any adverse effect on sensory properties and with concomitant cost savings.

A field study was conducted during rabi seasons of 2008 and 2009 to evaluated of productivity of Indian mustard (Brassica juncea L.) by foliar spray of bio-regulators under different irrigation environments. Amongst treatments, the application of sufficient irrigation water (four irrigations) recorded the highest number siliqua per plant, higher number of seeds per siliqua, 1000 seed weight and yields as compared to all other irrigation treatments. Results show that an increased in seed yield of 92.40 and 39.37 % under sufficient irrigation and limitedwater condition in 2008 and 93.34% and 40.31% in 2009, respectively over deficient irrigation conditions, foliar sprays of 100 ppm thioglycollic acid at initiation of branching were recorded highest yield attributes and yields. Similarly, 500 ppm of thiourea at initiation of branching and flowering stages also gave second best highest yield attributes and yields as compared to all other bio-regulators spray stages. However, bio-regulators sprays were not recorded any significant effect on oil and protein content. The results were concluded that economic feasibility to improve productivity of Indian mustard with four irrigations levels and sprays of 100 ppm thioglycollic acid and 500 ppm of thiourea at initiation of branching and flowering stages under hyper arid environment.

The mutagenic effects of different dose/concentrations of gamma rays (30, 40 and 50 KR) and ethyl methane sulphonate (1.0, 1.5 and 2.0 mM) on sesame (Sesamum indicum L.) varieties VRI-1 were investigated. The characters studied include; days to first flower, plant height, number of branches per plant, number of capsule per plant, number of seeds per capsule and seed yield per plant in M2 and M3 generations. Both negative and positive shifts in mean values were recorded as a result of the physical and chemical treatments. The results indicate the possibilities of evolving higher yield variants through proper selection. Thus, economic traits like number of capsule per plant, number of seeds per capsule and hundred seed weight in M3 generation offer scope for selection and improvement.
