This study was performed to determine the sensory evaluation and mechanical characteristics of lemon red ginseng-pyun. Lemon red ginseng-pyun was made with lemon juice(21.4%), sweet potato starch(6.7%), water(53.3%), sugar(13.3%), honey(5.3%) and various concentrations of red ginseng powder(0, 2, 4, 6, 8, 10%). The quality characteristics of the sample were estimated in terms of pH, color difference, texture profile analysis and sensory evaluation. The pH of lemon red ginseng-pyun showed no significant difference among the different ratios of red ginseng. With increasing red ginseng powder addition, the lightness was significantly(p<0.05) lower, and a value and b values were significantly(p<0.05) higher. In sensory evaluation, with increasing red ginseng powder addition, the color and bitter taste of lemon red ginseng-pyun were stronger, while clarity of the 10% added red ginseng was significantly(p<0.05) lower than that of the 0% added red ginseng. Elasticity, hardness, chewiness, softness. sweet taste and overall acceptability were not significantly different in any group. In texture profile analysis, chewiness, cohesiveness, gumminess and hardness were significantly(p<0.05) increased in the 10% added red ginseng but springiness was not significantly different in any group. Overall acceptability was related to texture, appearance, overall taste and sweet taste of lemon red ginseng-pyun. Therefore, development of lemon red ginseng-pyun with no sugar or artificial sweeteners is encouraged as a healthy diet for diabetes and hypertension patients, because red ginseng is defined as a functional foods.

This study was carried out to examine the sensory characteristics of Demi-glace sauce prepared by fresh basil with different amount of salt added. The evaluation of the sensory quality of Demi-glace sauce prepared by fresh basil was conducted by unexperienced and trained panel with regard to color, odor, taste, appearance, texture, viscosity, and overall acceptability while varying the quantity of salt added, the time of preparation, and the conditions of sauce offered in which each panel was supposed to evaluate both sauce itself and sauce with meat. It was found that Demi-glace sauce prepared by fresh basil with 0.3% salt added was gained the highest score from both panels in most properties and the second was the one with 0.1% salt added. In the sensory properties correlation analysis according to the time of preparation and the conditions of sauce offered, there was no significant correlation in most sensory properties for the unexperienced panel, except some significantly positive correlation between taste and overall acceptability of the sauce. Whereas there was a positive correlation in the majority of sensory properties for the trained panel regardless of the time of preparation and the conditions of sauce offered. The sauce with 0.3% salt added ranked as the best recipe by both panels among four different ratios of salt adding regardless of the time of preparation and the conditions of sauce offered. Triangle test showed that the sauce B with 0.1% salt added before the preparation was more highly appreciated in terms of taste than the sauce A with 0.1% salt added in the final step of preparation. In conclusion, it could be suggested that Demi-glace sauce prepared by fresh basil with 0.3% salt added is the best recipe for commercial products. Also, there seems to be the need of further sensory evaluation studies on the Demi-glace sauce according to the time of addition during the process of preparation.

To confirm the influence of modified starch on frozen storage stability, the microstructure and sensory characteristics of fish cakes, called Eomuk in Korea, by using seven varieties of starch, including native starch (NS), physically treated corn starch (MS) and modified starch [treatment with acetate (SA-1, SA-2 and SA-3), hydroxypropyl (HS), and acetylated distarch adipate (ADA)] were evaluated. Scanning electron microscopy (SEM) photographs showed fish cakes with NS had a finer and denser network structure than those made with modified starches. During frozen storage, fish cakes with HS and ADA exhibited a stable structure, as evaluated by porosity and rough surface. The results of the sensory evaluation showed that modified starch, including HS, SA-2 and ADA, increased the taste and firmness of the fish cakes, while NS, MS and the modified starch SA-3 resulted a decrease in the sensory properties during storage. Therefore, HS, SA-2 and ADA are suitable additives to improve the sensory quality of frozen fish cakes.
