  • This study was carried out to evaluate the effects of black sesame powder on bread quality. Breads were prepared by the addition of 0, 2.5, 5.0 and 7.5% of black sesame powder to the basic formulation. The weight of bread with black sesame powder ranged from 522.0 to 532.0 g and that of the control was 516.0 g. The volume of the bread prepared by adding 2.5, 5.0 and 7.5% black sesame powder was 2250.0, 2290.0, and 1800.0 mL, respectively. The water absorptive rate of bread with added black sesame powder decreased 3.83 to 2.48 and that of the control was 5.28. The lightness, redness and yellowness values of the bread decreased with the increase of black sesame powder. The hardness increased with the addition of black sesame powder, and was the highest for the bread with added 7.5 % black sesame powder. The sensory quality of the black sesame powder-bread as estimated by taste, and overall acceptability was better than that of the control product, and especially the quality of the bread with the addition of 2.5% black sesame powder was the best.

  • In this study, we evaluated the effects of sesame powder on the fermentation of Baechukimchi, by assessing sensory, physicochemical, and microbiological properties during up to 25 days of fermentation. The Baechukimchi, with various levels [0, 1, 2, 3, 4%(w/w)] of sesame powder, was fermented at $10^{\circ}C$. The product containing the control and 1% sesame powder evidenced the highest scores for appearance and smell. Taste and texture were highest in the 1% and 2% sesame powder, and the overall acceptability was highest in the 2% sesame powder sample. During fermentation, titratable acidity increased while pH gradually decreased. pH was higher in the sample with sesame powder than in the control, and the titratable acidity increased with increasing sesame powder content on day O. Reducing sugar increased sharply during fermentation, and then gradually decreased. In particular, the 2% sesame powder sample maintained the highest content. Total vitamin C was slightly increased at initial fermentation and then steadily decreased. The total polyphenol content and antioxidant effect of the experimental groups with added sesame powder were higher than those of the controls. Additionally, the time required to achieve maximum levels of lactic acid bacteria, as determined by log numbers of cells and total viable cells, were more delayed in the experimental groups with added sesame powder than in the controls. Our results indicated that the Baechukimchi with $1{\sim}2%$ added sesame powder was acceptable.

  • In this study, we applied a steam treatment to black sesame to determine the optimum treatment conditions, and also examined the antioxidant effects and quality characteristics. For black sesame gruels, roasting can be used in a variety of ways in cooking to enhance functionality and preference. We found that the solid content increased with the addition of 70% steamed black sesame in the glutinous rice-black sesame gruel samples, and for glutinous black rice-black sesame gruels, solid content was highest with the addition of 50% steamed black sesame. For the chromaticity, the L-value decreased as the addition of steamed black sesame increased in all the black sesame gruels made with the steamed black sesame. With regard to texture, the cohesiveness, springiness, gumminess, chewiness, and adhesiveness of the gruels made with steamed black sesame were highest when 60% steamed black sesame was added. The results of the sensory test showed that overall preference was highest for the glutinous rice-black sesame gruel made with 60% steamed black sesame, while the glutinous brown rice-black sesame gruels were preferred with 60% and 70% additions, and the glutinous black rice-black sesame gruel was deemed best with 60% steamed black sesame. The most appropriate ratios of steamed black sesame in the black sesame gruels, with regard to overall quality, are as follows: 60% steamed black sesame for the glutinous rice-black sesame gruel, 60% and 70% steamed black sesame for the glutinous brown rice-black sesame gruel, and 60% steamed black sesame for the glutinous black rice-black sesame gruel.

  • The purpose of this study was to survey the various kinds of cooked beef products focusing on 'Chim' (a steamed beef products) through historical literatures written from 1670 to 1945 in korea. 'Chim' was recorded 25 times in the references and could be classified to 5 groups based on major ingredients such as stomach, intestine, lean meat, tail and ribs. Among the eleven cooked products of 'Chim', 'Kalbi-chim' (a steamed ribs) was recorded most frequently and 'Sundae-chim' (sausage-like product) was the next. Though 'Kalbi-chim' has been used untill present day but 'Sundae-chim' was disappeared in the early 19th centuries. Ribs were most popular ingredient among the major ingredients such as stomach, intestines, lean meat, tail, feet and ribs. Twenty one kinds of subingredients including pheasant meat, blood clot and flour were used for 'Chim'. Decorating ingredients such as roasted sesame power, pine nut and thin-layer fried eggs and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and sesame oil were used for 'Chim'.

  • This study investigated the quality characteristics and antioxidant effects of black sesame gruel made with different concentrations of 15 minutes of treatment at $100^{\circ}C$ roasted black sesame. Total lignans showed the highest levels with 15 minutes of treatment at $100^{\circ}C$ roasted black sesame. With regard to lecithin's antioxidant effects, 15 minutes of treatment at $100^{\circ}C$ roasted black sesame showed a higher oxidation restriction rate. Hydroxyl radical scavenging, a similar scavenging activity to tocopherol, and a comparatively higher scavenging activity than sesamol, was shown with 15 minutes of treatment at $100^{\circ}C$ roasted black sesame and showed scavenging abilities of 90% and higher. For black sesame gruels, roasting can be used in a variety of ways in cooking in order to enhance functionality and preference. The most appropriate ratios of $100^{\circ}C$, 15minutes roasted black sesame in black sesame gruels, with regard to the overall quality characteristics, are as follows: The results of the sensory test showed that the overall preference was highest for glutinous rice-black sesame gruel, glutinous brown rice-black sesame gruel, and glutinous black rice-black sesame gruel, which were deemed best with 50% black sesame. From the above results, it could be seen that glutinous rice, glutinous brown rice, and glutinous black rice black sesame gruels, which are made by adding 50% roasted black sesame, contributed to enhancing the function of antioxidant activation and development quality.

  • In this study, the physicochemical characteristics of imported whole sesame oil (WS; WS1, WS2), imported sesame powder oil (SP; SP1, SP2), sesame oil mixed with imported whole sesame and sesame powder (WSP; WSP1, WSP2) were analyzed and their quality characteristics were compared according to the imported raw material type. $L^*$ and $b^*$ values of WS1 were the lowest and the browning index was significantly high. WS2 showed contrasting results. The redness of sesame oil was high due to its high acid value. The correlation value showed a low acid value as the content of saturated fatty acid was high. SP showed low values for antioxidant property and overall preference. The overall preference score of sensory evaluation showed the highest positive correlation with the score, suggesting that SP lacked the unique fragrance. Therefore, SP lacked the specific aroma and antioxidant property.

The quality and sensory characteristics of sesame dasik that were evaluated were moisture content, water activity, number of microflora, texture profile, Hunter color different value, and sensory properties (color, chewiness, overall acceptability, etc) during the storage at 35\pm1^\circ{C}$ temperature and $73\pm{2%}$ relative humidity. And the packaging materials were paper boxes (coated 0.02mm thickness polyethylene film), plastic boxes, and oriented polypropylene laminated film. Traditional sesame dasik is made from sesame powder 100g, honey 25g, rice syrup 25g, and table salt 0.5g. During the storage period, the changes in water content and water activity of sesame dasik with different packaging material showed a slight decline. On the other hand, it increased in hardness, and "a" and "b" value of Hunter color difference during the storage. Texture profile analysis data change in hardness was the greatest after the third day in a paper box, and it was affected by the moisture content of dasik and the temperature and relative humidity of the air. Therefore plastic boxes or oriented polypropylene laminated film was found to be better suited than paper boxes for storing sesame dasik.
