        The antioxidant, physicochemical, and sensory properties of muffins using fermented Curcuma longa L. were investigated. Sensory properties of the samples were examined, and the correlation between the physicochemical, antioxidant, and sensory properties was studied. The pH of the samples was pH 7.26-7.42, which was the optimal pH range for the air formation of the dough, color, or volume. The antioxidant activities of the sample group were significantly higher than the control (p<0.05). In the sensory intensities, the 1.0 and 1.5%-added sample groups showed a similar savory aroma, sweet aroma, savory taste, sweet taste, and texture to those of the control. Samples containing 1.0 and 1.5% showed similar overall acceptance values to the control. The muffin containing 1.0 or 1.5% fermented Curcuma longa L. powder was developed successfully, and it was concluded that the developed muffin with the fermented turmeric powder could be a highly valued product in the increasingly competitive muffin food industry.

        This study investigated the sensory characteristics and antioxidative activity of the reduced salt dried bulgogi bibimbap containing AF-343, a dandelion-derived compound extract. A sample with a 30% reduced salt had a sodium amount of 659.01 mg, which was significantly lower than that of the sample before the reduction (p<0.05). The textural hardness of the SW (Standard sample with the AF-343), showed the lowest value of 1.03 N/cm2, indicating that the AF-343-containing sample could have a slightly softer texture than the non-containing sample. In the analytical sensory test, the AF-343- containing samples showed a synergistic effect on the aroma and flavor of bulgogi, with values of 5.7 and 8.4, respectively, which were significantly higher than that of the non-containing sample group (4.3 and 4.4, respectively). The hardness by the sensory test was slightly hard with values of 7.2-8.1 in all samples, indicating that textural improvement was needed. In the acceptance test, all the samples scored with slightly lower values of 4-5 points, highlighting the need for future studies to improve the sensory characteristics of dried bibimbap. The flavonoid contents of AF-343-containing SW and RW sample groups were 68.21 and 64.31 mg GAE/100 g, respectively, which were significantly higher than those of the samples without AF-343 (49.06 and 44.82 mg GAE/100 g, respectively) (p<0.05). The ABTS and DPPH radical scavenging activities were similar to those of the flavonoid contents. As a result, in the production of AF-343-containing reduced-salt dried bulgogi bibimbap, more study on the textural improvement will be needed to achieve better palatability.

        We investigated the antioxidant, physicochemical, and sensory characteristics of dried type sodium-reduced bibimbap using dandelion complex powder (DCP). DCP is known to add moisture to the skin and relieve symptoms of atopic dermatitis. The sodium content of the standard sample was 1,110.87 mg per serving. The sodium was significantly reduced by 30%, resulting in 762.62 mg of sodium for the reduced sodium group (p<0.05). The ash contents of the standard sample group with DCP showed the highest value (3.17%) in all samples and was affected by minerals of DCP (p<0.05). The total flavonoid contents and ABTS radical scavenging activity, indicators of antioxidant, anticancer and antibacterial activities, showed significantly high activities with addition of DCP (p<0.05). In the sensory results, bulgogi and savory flavor of the samples with DCP showed significantly higher values, and samples with DCP received the highest scores for after-taste. All samples were confirmed to be microbiologically safe according to the food code applied to food manufacturers. Pathogenic microorganisms tests were either negative or not detected in all samples.

        Korean style DASH (Dietary Approaches to Stop Hypertension) and a dietary education program for sodium reduction were developed. Reduced sodium diets (15 and 30% reductions) were developed from general diets for 3 consecutive weeks from Monday through Saturday. Subjects (19 total) were classified into two groups according to dietary education. Experimental period was from June 24 to July 23, 2012. Total sum of adaptation scores for low sodium diets significantly increased in the group that underwent dietary education compared to that without (p<0.05). After the experiment, both groups showed significantly increased values in terms of food group balance, sodium-related nutrition knowledge, attitude, and practice by paired t-test. Especially, group that underwent dietary education showed significantly higher values for attitudes by ANCOVA pre-test as a variation (p<0.01). For the results of the nutrient intake survey, group that underwent dietary education showed significantly increased values for dietary fiber (p<0.01), vitamin A (p<0.001), vitamin K (p<0.001), vitamin C (p<0.01), Folic acid (p<0.001), vitamin B12 (p<0.01), calcium (p<0.01), iron (p<0.05), and zinc (p<0.05) and significantly decreased values for sodium (p<0.05) and chloride (p<0.005). Subjects adapted to reduced sodium diets showed apparent improvements in sodium-related knowledge, attitude, practice and intake of nutrient, and these improvements were even higher in the group that underwent dietary education compared to that without. Thus, adaptation to low sodium diet combined with dietary education can improve dietary habits.

        This study investigated the antioxidative activities and quality characteristics of gruel as a home meal replacement with Angelica keiskei powder pre-treated by far-infrared radiation or freeze-drying methods. Far-infrared treated Angelica keiskei powder (F-IAP) showed significantly lighter, weaker green, and stronger yellow color values than powder subjected to freezedrying (FAP) (p<0.001). F-IAP showed higher total phenolic compound contents than that of the FAP. ABTS radical scavenging activity of F-IAP was 50.31%, which was significantly higher than that of FAP, at 43.51% (p<0.05). Color values of gruel significantly decreased with increased addition of Angelica keiskei powder (p<0.05). Gruels containing far-infrared treated Angelica keiskei powder (F-IAG) showed higher total phenolic compound contents as well as ABTS radical scavenging activities compared to the gruels containing freeze-dried Angelica keiskei powder (FAG). Gruels containing 5 g of Angelica keiskei powder showed 2.0 to 2.5 times higher antioxidant activities than those containing powder alone due to the presence of other ingredients with antioxidant activities such as black soybean or sweet pumpkin. In the results of sensory evaluation, F-IAG containing more than 5 g of Angelica keiskei powder had higher sweetness and roasted grain flavor, as well as lower bitterness and astringency compared to FAG. Sensory acceptance tests of all samples showed higher scores than 5.0 representing possibilities of successful development of gruels as a home meal replacement containing Angelica keiskei powder.

        We conducted this study to investigate the quality characteristics of mashed red pepper(MRP) with different freezing(-20, -30, -40, -50, -60 or -70℃) and thawing(4, 10, 20, 30, 40 or 50℃) temperature. Frozen and thawed MRP was evaluated for ascorbic acid contents(AsA), capsaicinoids contents, free sugar contents, ASTA value, and flavor patterns. The AsA of frozen MRP with freezing temperature showed a range of 67.08~80.35 ㎎/100 g FW, and the mean AsA losses after frozen were 57~64% compared to raw red pepper. Capsaicinoids contents, free sugar contents, and ASTA values of frozen MRP with freezing temperature were no significant difference compared to raw red pepper. The AsA of thawed MRP with thawing temperature showed a range of 70.34~81.59 ㎎/100 g FW, and the mean AsA losses after thawed were 45.12~52.69% compared to raw red pepper. Capsaicinoids contents and free sugar contents of thawed MRP with thawing temperature were no significant difference compared to raw red pepper, whereas the ASTA value decreased according to the increasing of thawing temperature. Flavor patterns of thawed MRP after 20~50℃ thawing were clearly different from the raw red pepper. Overall, it is recommended that the best freezing and thawing temperature for preserving the quality of MRP is freezing at -20℃ and thawing at 10℃.

        This study was performed to investigate flavor modification effects of β-cyclodextrin (β-CD) inclusion complex on the flavor of Doenjang (Korean traditional fermented soy paste) with various substitution levels of 10, 20, and 30%. Water and protein contents of the substituted samples showed significantly lower values compared to those of control(p〈0.05). Results of DSC(Differential Scanning Calorimetry) showed that significantly higher δH values (386.03 and 304.23) in the 20 and 30% substituted samples represented the stabilized internal cell structures(p〈0.05). Internal structures observed with the scanning electronic microscope tended to be less rough and organized making even and ordered internal cell structures as the substitution levels were increased. Results of sensory evaluation showed significantly higher savory flavor and significantly lower bitter and astringent flavors with the substituted samples compared to those of control(p〈0.05). Results from this study showed the substitutions of β-CD could possibly modify unfavored flavors of Doenjang while keeping the unique, nutritional and functional properties when β-CD was used as a flavor modifier.
