“…The world production of sesame seed progressively increased due to an increasing demand for sesame oil worldwide. In fact, sesame oil is highly stable and rich in unsaturated fatty acids (Carvalho et al, 2012). Consequently, sesame oil ranks sixth in the world among vegetable oils and Myanmar becomes the first seed producer of sesame in the world, followed by India.…”

ABSTRACT. This study was conducted in order to evaluate the response of sesame seeds (Sesamum indicum L.) to organic or mineral fertilization. The effects of two fertilizers, which were calcium nitrate and humic acids were studied separately at germination and early seedlings growth. Different concentrations of humic acids (HA 0 : 0, HA 1 : 500, HA 2 : 1000 and HA 3 : 2000 mg L -1 ) or calcium nitrate (CaN 0 : 0, CaN 1 : 50, CaN 2 : 100 and CaN 3 : 200 mg L -1 ) were applied distinctly to the growth media. The experimental design was accomplished in a completely randomized block design with three replications. Germination measurements, seedlings length, fresh seedling weight, total chlorophylls and carotenoids, total soluble proteins and sugars were determined. Results showed that humic acids applied at 1000 mg L -1 or calcium nitrate applied at 100 mg L -1 reduced the mean germination time (3.5 and 3.61 days) and had the highest germination index (GI) and the highest coefficient of velocity (CV). The longest seedling was obtained at the concentrations HA 2 and CaN 2 (+22%). Total chlorophyll and carotenoids were significantly higher in seedlings receiving the HA 2 and CaN 2 and these treatments increased total soluble proteins content by 32%. Higher concentrations of humic acids or calcium nitrate HA 3 and CaN 3 delayed germination and enhanced proline and total soluble sugars, respectively, by 42% and 46%, compared to control. These preliminary results indicated that the use of fertilizers should be optimized and they can be transformed at high level to an abiotic stress menacing plant productivity. On the other hand, suitable concentrations of fertilizers can be used in the future as a remedy to improve growth under abiotic stress.

“…In addition to being used as an emulsifier, the oil is rich in unsaturated fatty acids (palmitic, stearic, oleic, and linoleic acids) [14] and has anti-cholesterol property [15]. It is widely consumed as nutritious food, very beneficial to health, as cooking oil, in pharmaceuticals, in shortening and margarine, as soap fat and as synergist for insecticides [16,17].…”

Sesame oil is widely consumed as nutritious food, cooking oil, and in pharmaceuticals and food. In this study, the antinociceptive and anti-inflammatory properties of the sesame oil and sesamin were investigated. The sesame oil and sesamin reduced the number of abdominal contortions at the doses 100, 200, or 400 mg/kg. The first and second phases of the time paw licking were inhibited by sesame oil and sesamin (100, 200, or 400 mg/kg). After 90 min of treatment, sesame oil and sesamin increased the reaction time on a hot plate (200 or 400 mg/kg). Considering the tail-immersion assay, the sesame oil and sesamin produced significant effect after 60 min at the doses of 100, 200, or 400 mg/kg. After 4 h of application of the carrageenan, the sesame oil and sesamin were effective against the paw edema. The exudate volume and leucocyte migration were also reduced by sesame oil and sesamin. These results suggest that sesamin is one of the active compounds found in sesame oil and justify the antinociceptive and anti-inflammatory properties of this product.

“…The experimental results were used to develop a model of the extraction process. Many researchers have considered the Henry isotherm because the Henry relation is simple and linear (Goto et al, 1996;Reverchon, 1997;Gooderznia and Ekani, 1998;Reverchon, 2001;Carvalho et al, 2012). Goto et al (1998) Ghoreishi et al (2001) employed the Freundlich isotherm for the modeling of supercritical extraction of mannitol from pane tree leaf.…”

-Mathematical modeling of supercritical fluid extraction of oil from canola and sesame seeds with a two-phase model was performed in this work. A model based on differential mass balance was used to correlate the experimental data. Different adsorption isotherm models (Henry, Freundlich and Brunauer, Emmet and Teller (BET)) were used to describe the equilibrium state. Three model parameters such as effective diffusivity (D eff ), mass transfer coefficient (K f ) and axial dispersion coefficient (D ax ) of the bed were used as fitting parameters. The experimental data for yields were obtained at pressures of 10-20 MPa, temperatures of 313-333 K and solvent flow rates of 2-4 g/min. From the results, a nonlinear adsorption isotherm exhibited better agreement with experimental data of yield than a linear model in the range of studied conditions.
