  • The objective of this study was to develop black sesame gruel with high-dietary fiber rice, 'Goami 2'. Physical and sensory properties of black sesame gruel with various ratios of black sesame by weight (20, 40, 60%) and various water volumes(1100, 1200, 1300 mL) were investigated using colorimeter, consistometer, viscometer, sensory evaluation panel and consumer evaluation. The black sesame content significantly(p<0.001) affected the mechanical characteristics(color, consistency and viscosity), sensory characteristics(blackness, glossy, nutty, astringent taste, bitter taste and viscosity) and sensory acceptance(color acceptance, taste acceptance, viscosity acceptance and overall acceptance). The water content significantly(p<0.05) affected the mechanical characteristics(consistency and viscosity), sensory characteristics(viscosity) and sensory acceptance(taste acceptance, viscosity acceptance and overall acceptance). In the black sesame gruel, as black sesame weight ratio increased, the brightness, redness, yellowness and viscosity were decreased while the consistency, blackness, glossy, nutty, astringent taste and bitter taste were increased. In the sensory evaluation results, the optimal material mixing ratio for gruels was black sesame : Goami 2 = 40(80 g) : 60(120 g), water 1200 mL.

  • The aim of this study was to develop a standardized recipe for black sesame gruel that has been preferred for generations as a nutritional food. The method focused on optimizing the mixing ratio of the components to improve the quality of the black sesame gruels that modem consumers would like. The results are summarized as follows: The more black sesame added to the gruel, the lower its brightness was, but the redness and yellowness was higher. The amount of black sesame made a significant difference in the viscosity, color, nutty taste, bitterness, appearance and overall preference. It was highest in the overall preference when the amount of black sesame was added 33g(40% of rice weight basis). Different types of rice were added to the black sesame gruel, and it was observed that the color value of the gruel was high in its brightness, redness and yellowness when 50g(60%) of glutinous rice was added to it. The black sesame gruel was most preferred when 50g of non-glutinous rice was added. The redness value was high when 15g(18%) of non-glutinous rice flour was added. The yellowness value was high when 25g(30%) of non-glutinous rice flour was added. This observation showed significant differences in the viscosity, color, nutty taste, bitterness, appearance and overall preference. In particular, the black sesame gruel was most preferred when 50g of non-glutinous rice flour was added. The addition of 7g(9%) of salt to the black sesame gruel showed the highest brightness. The redness and yellowness was the highest when 5g(6%) of salt was added. This observation showed a significant difference in the viscosity, color, nutty taste, bitterness, appearance and overall preference. The highest preference was observed when 2.5g(3%) of salt was added. Adding more materials increased the viscosity of the black sesame gruel. With increasing temperature, the viscosity became lower, and vice versa. The intensity of sweetness and spreadability was found to be proportional to the amount of additive material. In conclusion, the optimum recipe for black sesame gruels was obtained 33g(40%) of black sesame, 50g(60%) of glutinous rice (flour), 2.5g of salt, and 500$m\ell$ of water.

  • As the major quality deterioration factor for black sesame Dasik during storage, texture hardening, loss of gloss and decrease of savory flavor are derived from sensory and texture analysis of fresh and two months-stored Dasik. Four kinds of corn syrup with different dextrose equivalent (DE) were applied and their effects on quality attributes of black sesame Dasik were examined to select the optimum corn syrup that could minimize the quality deterioration of black sesame Dasik during storage. Results of texture analysis and sensory evaluation of fresh and four weeks-stored Dasik at $25^{\circ}C$ suggested the possibility that the application of corn syrup with DE of 60~65 or oligosaccharide can minimize the quality deterioration of black sesame Dasik in terms of gloss, sweet flavor and texture hardening during storage.

  • White and black sesame produced in Korea were defatted with ethyl ether or n-hexane. Defatted sesame meal was extracted with water and salt solution, and protein extraction was precipitated at various pH 1 through 12, with trichloro acetic acid (TCA), tannic acid and ammonium sulfate, respectively. Protein was purified by Sephadex A-25, G-75, G-100 and G-200, and identified its protein fraction by polyacrylamide gel electrophoresis. Amino acids composition of protein in white sesame was analyzed by automatic amino acid analyzer. Protein contents of white sesame, black sesame and sesame meal are 20.5%, 19.2%, and 44.7%, respectively. n-Hexane was the most suitable solvent for extraction of oil from sesame. Crude protein precipitation was better in higher pH. The protein extraction was more effective with the solution containing sodium chloride tinder the pH 8. Globulin in total protein was high and prolamin was less than in other cereal proteins. Glutamic acid contents of white sesame and sesame globulin were 17.1%, and 20%, respectively. Both proteins contained relatively high levels of essential amino acids. 12-13 bands were found in water soluble protein and 2 bands in salt soluble protein were detected by the disc gel electrophoresis, and were identified in both of white and black sesame. The salt soluble protein of white sesame could be purified by Sephadee G-100 and G-200.
