  • Purpose: This study was conducted to optimize the conditions of manufacturing the wet noodle added with Aloe powder. Methods: The I-optimal design of response surface methodology (RSM) was used for the optimization of added amount of Aloe powder, water content, and kneading time as the independent variables. The quality characteristics (color, texture, water absorption ratio, volume, turbidity) and sensory characteristics (color, flavor, taste, mouth feel, overall acceptance) were analyzed as dependent variables. Results: The lightness, redness, and yellowness of the Aloe noodle were all lowered with the addition of Aloe powder. All texture characteristics such as hardness, elasticity and chewiness of Aloe noodle showed the tendency to increase with increasing amount of Aloe added and kneading time. The water uptake and the volume expansion tended to increase with increasing aloe addition and water addition. As the kneading time increased, the dissolution of solids decreased and the turbidity tended to decrease. Aloe powder content influenced the color, flavor and taste of the noodles most among independent variables, and the mouthfeel of the noodle influenced by the water addition and the kneading time. Conclusion: Aloe noodle showed the best desirability with 3.03% of Aloe powder, 43.56% of water content and 13.06 min of kneading time by RSM analysis. Aloe noodles prepared under these optimized conditions are expected to be able to manufacture and utilize functional Aloe noodles by meeting the content of isobarbaloin, which helps the intestinal functional activity.

  • The purpose of this study was to investigate the effects of dill on the quality characteristics of tomato sauce during 60 days of storage. As storage time increased, the pH stays between 4.10-4.22 on all additives. The lowest pH appeared on a 0% dill added sample during the storage period, except at 45 or 60 days of storage. The more dill was added, the less sugar appeared, and this was generally consistent across other samples. As storage times increased, the sugar content showed a tendency to decrease in all additives. Salinity turned out to be between 0.90-1.48 among all of the additives. For the L-value, the more dill was added, the less the L-value decreased, and this was consistent across all the samples. As the storage period increased, the L-value showed a tendency to decrease in all samples. The more dill was added, the more the a-value showed a tendency to decrease. The b-value showed a tendency to decline the more dill was added. Also, as storage time increased, the b-value decreased in all samples. Viscosity showed a tendency to increase in all samples the more dill was added. The reducing sugar content was kept between 44.83-55.38. A sensory evaluation was performed by 15 professional panelists with scoring tests for color, flavor, taste, aftertaste, viscosity, and overall acceptability. The tomato sauce with 2% dill showed the best score in the color, flavor, and overall acceptability. From the above results, the data suggests that an addition of 2% fresh dill to tomato sauce is recommended for commercial use.

  • Purpose: This study was conducted to investigate the effect of cabbage powder on the quality characteristics of rice nutritional bars. Methods: In order to analyze quality characteristics, total phenolic content, DPPH free radical scavenging activity, baking loss rate, leavening rate, specific volume, moisture content, color, texture analysis, and sensory evaluations were assessed. Results: The total phenolic content and DPPH free radical scavenging activity of rice nutritional bars significantly increased with an increase in the content of cabbage powder (p<0.05). The baking loss rate, leavening rate, specific volume, and moisture content of the rice nutritional bars were significantly reduced as the amount of added cabbage powder increased (p<0.05). As the concentration of cabbage powder increased, the lightness and redness of the bars' crust and crumbs decreased, while yellowness increased (p<0.05). In texture analysis, the control bars showed the highest hardness values. Adhesiveness, springiness, and cohesiveness values slightly decreased with higher cabbage powder content in the groups with added cabbage powder (p<0.05). When consumer acceptability was measured, rice nutritional bars prepared with 15% cabbage powder showed the highest scores in color, whereas the rice nutritional bars prepared with 20% cabbage powder showed the lowest scores in flavor (p<0.05). In characteristic intensity rating, the taste and off-flavor of rice nutritional bars significantly increased with increasing amounts of cabbage powder (p<0.05). Conclusion: Judging from our results, it can be concluded that the addition of cabbage powder to rice nutritional bars during processing can enhance consumer preference for the bars, total phenolic content, and DPPH free radical scavenging activity.
