  • This study was performed to investigate the storage properties of emulsion-type sausage added with Glycyrrhiza uralensis and Curcula longa hot water extracts (GCHE) extracted at $10^{\circ}C$ for 35 days. The TBARS values of sausages containing 1.0 and 5.0% GCHE were lower than that of control. The bacterial count and VBN contents of all the samples were significantly increased during the storage periods, except the group with 5.0% GCHE. The redness of all the samples was lower than that of control, while yellowness of all the samples was higher than that of control. The nitrite scavenging abilities of the sausages containing 1.0 and 5.0% GCHE were higher than that of the control. It is suggested that the addition of 1.0% hot water extracts extracted from these plants may be a potential substitute for the use of nitrite to extend shelf-life of sausages.

  • Various health benefits of turmeric have been reported. Therefore, an innovative application of turmeric as a functional food was explored. In the current study, effects of an extrusion process on the chemical properties and antioxidant activities of turmeric were investigated. Extrusion of turmeric was performed at $150^{\circ}C$ using screw revolution speeds of 500, 1,000, 1,300, and 1,600 rpm. A significant reduction in turmeric pigments and the formation of browning compounds occurred due to the extrusion. The degradation of pigments was proportional to the increase in screw speed. Infusion yields were significantly increased after the extrusion. The content of proteins and polyphenols, as well as the content of flavonoids in infusions and EtOH extracts were significantly reduced by the extrusion. Scavenging activities of turmeric against DPPH and ABTS radicals were also significantly reduced following the extrusion. These results indicate that the extrusion process caused a significant loss of pigments and decreased the antioxidant activities of turmeric. Therefore, further study related to the development of a proper extrusion process is to be needed.

  • This study was to examine the shelf life and qualities of castellas added with mixture of Morus alba root bark (MA), Ecklonia stolonifera (ES), and Curcuma aromatica (CA) extracts (MECE). The result of total microbial cell count showed that castellas with MECE were increasing storage time, especially at the rate of MA : ES : CA=0.75:0.75:0.5, and was reduced about 3 log cycle as compared to that of control. Also castellas with MECE were shown to have the highest antioxidant effect by Rancimat method. In the color, redness of castellas diminished with increasing amounts of MECE in castellas while conversely, lightness and yellowness increased. In sensory evaluation, the castella containing MA 0.25%, ES 0.25% and CA 0.125% were preferred than the control. These results suggest that the addition of MA 0.25%, ES 0.25% and CA 0.125% in castella positively improved the preservation and development of quality.

  • This paper describes a methode to extract yellow pigment from curcuma and turmeric containing natural color curcumin whose target color indexes of L, a, and b were 87.0 7.43, and 88.2, respectively. The pH range and extraction temperature used for the reaction surface analysis method were from pH 3 to pH 7 and between 40 and $70^{\circ}C$, respectively for both natural products. A central synthesis planning model combined with the method was used to obtain optimal extraction conditions to produce the color close to target. Results and regression equations show that the color space and difference of curcuma and turmeric have the greatest influence on the value. In the case of curcuma, the optimum conditions to satisfy all of the response theoretical values of color coordinates of L (74.67), a (5.69), and b (70.08) were at the pH and temperature of 3.43 and $54.8^{\circ}C$, respectively. The experimentally obtained L, a, and b, values under optimal conditions were 72.92, 5.32, and 72.17, respectively. For the case of turmeric, theoretical numerical color coordinates of L, a, and b, under the pH of 5.22 and temperature of $50.4^{\circ}C$ were 82.02, 7.43, and 72.86 respectively. Whereas, the experiment results were L (81.85), a (5.39), and b (71.58). Both cases showed an error range within 1%. Therefore, it is possible to obtain a low error rate when applying the central synthesis planning model to the reaction surface analysis method as an optimization process of the dye extraction of natural raw materials.

  • Turmeric is a medicinal herb with various pharmacological activities. Curcumin, demethoxycurcumin(DMC) and bisdemethoxycurcumin(BDMC) were extracted from turmeric by dipping and ultrasonic wave method. And extraction efficiency was identified using solid phase extraction(SPE). The extracted sample were simultaneously separated and analyzed from three kinds of commercial $C_{18}$ reversed-phase high performance liquid chromatography using water and acetonitrile as mobile phase with isocratic elution mode. Flow rate 1.0mL/min, injection volume $10{\mu}L$ and column oven temperature $40^{\circ}C$ at 425nm wavelength has been conducted. From the experimental results, the optimum mobile phase composition of water/acetonitrile 50/50vol% using RS tech column. It is evident that the amount of curcuminoids extracted(extraction time 4h) by 100% MeOH was higher than any aqueous MeOH composition. Finally, in 100% water extraction, the amount(mAU${\times}$mim) of curcuminoids extracted by SPE was 14.3 and 24.5 times respectively higher than ultrasonic wave and dipping method. The shown results can be applied as sources for pharmaceuticals and functional material.

  • This study examined the improvement of bread quality with Curcula longa and Glycyorrhiza uralensis extract (CGE). When counted, the viable cell number in bread with 5% of CGE dramatically was decreased by about 1 log cycle as compared to that of bread without CGE. With regard to oxidation, the content of malonaldehyde diminished in breads with increasing amounts of CGE. Breads with 1 and 5% of CGE were shown to have the highest antioxidative effect. The moisture contents of bread with CGE and bread without CGE were not much different during the early storage period. After six days of storage, however, the moisture contents of bread without CGE and bread with 0.5% of CGE decreased about 16%. On the other hand, the moisture contents of bread with 1% and 5% of CGE did not change dramatically. Their moisture content was decreased by only 4% during the same storage period. Although color, lightness and redness gradually diminished with increasing amounts of CGE in bread, conversely yellowness increased. In the sensory evaluation, bread with 0.5% and 1% of CGE scored the highest: 3.66 and 3.67 out of 5, respectively. Bread with 5% of CGE scored the lowest of the various bread tested. From these results, the addition of 1% CGE in bread had a good effect on improvement of preservation and development of quality.

  • Physiological effects of curcumin, major yellow-colored pigment in tumeric (Curcuma longa L.), extracted by traditional extracting methods, ethanol and hot-water extractions, and supercritical fluid extraction (SFE) using supercritical carbon dioxide as new extracting method. Antioxidative activity of ethanol extract was higher than those of SFE and hot-water extracts. Results of Ames mutagenicity test on SFE, ethanol, and hot-water extracts revealed no mutagen in the extracts. Antimutagenicity rates of SFE, ethanol, and hot-water extracts against direct mutagen, 2-nitrofluorene (2-NF), were 20.1, 9.3, and 15.2%, respectively. Antimutagenicity rate of SFE extract against TA98 derived from indirect mutagen, 2-acetamidofluorene (2-AF), was 12.2%, whereas none was observed in ethanol and hot-water extracts. Nitrite-scavenging ability of SFE extract was higher than those of ethanol and not-water extracts.

  • This study was performed to examine the shelf life and qualities of wet noodle with Morus alba L. root and Curcuma aromatica extracts (MCE) during storage at $4^{\circ}C$. Lightness and redness of wet noodle were decreased with increasing amounts of MCE added in noodle while yellowness was increased. The viable cell and molds count of wet noodle with MCE was reduced about 1~2 log cycle as compared with control during storage time. Also the TBARS (thiobarbituric acid reactive substance) value of wet noodle with MCE was lower than that of control. Hence the wet noodle with MCE has shown remarkable antioxidation effect. In sensory evaluation, the wet noodle containing the ratio of 2.5:0.02 of M. alba : C. aromatica was preferred than the control. From these results, the addition of 2.5% of M. alba and 0.02% of C. aromatica extracts in wet noodle had a good effect on improvement of preservation and development of quality.
