  • The purpose of this study was to compare the sensory effects of different culinary methods such as electric pan cooking and charcoal roasting on gamma irradiated ready-to-eat chicken at 10 kGy. Evlauation of sensory properties were measured by estimating the organoleptic characteristics and physicochemical properties (TBARS, hardness and color different matters). The results showed that gamma irradiation after charcoal-roasting could more effectively moderate the decrease of sensory qualities and reduce off-flavor of ready-to-eat chicken than gamma irradiation after following electric pan cooking. These results suggest that gamma irradiation after charcoal broiling can be an effective culinary method for the preparation of ready-to-eat chicken.

  • This study was performed to aid the development of a reduced-calorie ssanghwa beverage, by using substitutes for high fructose com syrup(HFCS). Sensory scores were examined for ssanghwa beverages containing different levels of glucosyl stevia, aspartame, and acesulfame-K(0, 50, and 100%, respectively) in place of HFCS. The results showed that sensory scores were not significantly different for the beverages containing different levels of acesulfame-K, including aftertaste, ssanghwa taste, and overall eating quality. In contrast, the sensory scores of beverages containing 0 and 100% glucosyl stevia were significantly different. Data were also gathered comparing the sensory scores of beverages according to the different types of sweeteners. Bitter taste and astringency were not significantly different between the beverages sweetened with HFCS, KP(containing 50% acesulfame-K and 50% aspartame), SP(containing 50% glucosyl stevia and 50% aspartame), and SK(containing 50% glucosyl stevia and 50% acesulfame-K), respectively. Finally, aftertaste and overall eating quality were not significantly different between the HFCS and SP sweetened beverages.

  • This study investigated the effects of adding hard and soft wheat flour to Korean rice cakes(Karedduk) to retard retrogradation, by examining texture properties and descriptive sensory qualities after 2 and 24 hrs of storage at $5^{\circ}C$. The hard and soft wheat flour were combined with dry rice flour at levels of 0, 5, 10, and 20%. The texture properties, as analyzed by a Texture Analyzer, revealed that the springiness, cohesiveness, and adhesiveness of the rice cakes containing wheat flour were similar to those of the control, while chewiness, gumminess, and hardness were lower compared to the control. Also, in sensory analyses, hardness was significantly different in the rice cakes containing wheat flour compared to the control after 24 hrs of storage at $5^{\circ}C$. Overall, the instrumental texture properties were highly correlated with the sensory characteristics. These results suggest that adding hard and soft wheat flour to Korean rice cakes(Karedduk) is effective at retarding retrogradation.

  • We evaluated chemical, sensory and mechanical properties of breads containing different amount of Paecilomyces japonica powder to provide the basic informations for the development of functional bread. The pH of dough with 2% Paecilomices japonica powder was the highest but the pH of dough with 3% Paecilomices japonica powder was the lowest. Baking loss rate of bread added 3% Paecilomices japonica powder was the lowest but that of bread added 1% Paecilomyces japonica powder was the highest in that. The result of sensory evaluation showed that bread added 1% Paecilomices japonica Powder was significantly more preferable in chewiness, mouth feel, texture quality and overall quality. Sensory properties of softness, wheat flour odor, moisture, and mouth feel were positively correlated with the acceptability. Mechanical properties of hardness and chewiness had negative correlation with sensory properties, but springiness, gumminess and brittleness had positive correlation with those. The results of various measurements and evaluations showed that the quality of bread containing the Paecilomices japonica powder could be well accepted organoleptically. And this in turn proves the possibility of functional bread by use of Paecilomices japonica.

  • This study focused on the relationships among leaf and smoke components and sensory properties following tobacco leaf blending. A completely randomized experimental design was used to evaluate components of leaf and smoke and sensory properties for sample cigarettes with four mixtures of flue cured and burley tobacco (40:60, 60:40, 80:20 and 100:0). Eleven leaf components, six smoke components, and eight sensory properties of smoking taste were analyzed. A sensory evaluation method known as quantitative descriptive analysis was used to evaluate perceptual strength on a fifteen score scale. Raw data from ten trained panelists were obtained and statistically analyzed. Based on the MANOVA, clustering analysis, correlation matrix and partial least square (PLS) method were applied to find out which smoke component most affected sensory properties. The PLS method was used to remove the influence between explanatory variables in the leaf, smoke components derived from the results. High correlations (p<0.0l) were found among ten specific leaf and smoke components and sensory attributes. Total nitrogen, ammonia, total volatile base, and nitrate in the leaf were significantly correlated (p<0.05) with impact, bitterness, tobacco taste, irritation, smoke volume, and smoke pungency. From the results of PLS analysis, influence variables are used to explain about the correlation. In terms of bitterness, with only two explanatory variables, Leaf $NO_3$ and Leaf crude fiber were enough for guessing their correlation. In the distance weighted least square fitting analysis, carbon monoxide highly influenced bitterness, hay like taste, and smoke volume.

  • 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.

  • This study was aimed to compare the texture and sensory properties of Cream cheese and cholesterol-removed Cream cheese made from the whole milk powder (CRWMP) during storage at $7^{\circ}C$ for 4 wk. The cholesterol reduction by crosslinked ${\beta}$-CD was about 92% in CRWMP. In texture studies, hardness, gumminess, and chewiness had increased during the storage period of 4 wk in both cheeses, irrespective of treatment. In the sensory properties, cooked milk flavor was found to have decreased, whereas sourness had increased with increasing storage period of 4 wk in whole milk powder Cream cheese. On the basis of our results, we conclude that the cholesterol removal in CRWMP does not cause any adverse effect on the texture and sensory properties of Cream cheese made with whole milk powder.

  • Freeze-dried Ecklonia cava powder was incorporated into cookie dough at 5 levels (0%, 1.5%, 3%, 4.5%, and 6%, w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at $185^{\circ}C$ for 14 min in a convection oven. The baked cookies were cooled to room temperature for 30 min and packed in airtight bags prior to all measurements. Lightness $(L^*)$ decreased significantly as the E. cava powder content increased (p<0.05) and a decreasing trend in both redness ($a^*$-value) and yellowness ($b^*$-value) was observed. On the other hand, firmness increased significantly with an increase in E. cava powder content (p<0.05). Increases in E. cava powder concentration up to 6% in the cookie formulation significantly increased the intensities of all sensory attributes such as color, flavor, taste, and firmness (p<0.05). Correlation analysis indicated that the E. cava concentration correlated significantly with most of the properties except for $a^*$-value (p<0.01, 0.05, or 0.001). Properties such as firmness and sensory color and firmness correlated positively while $L^*$- and $b^*$-value correlated negatively with E. cava concentration. Sensory color correlated negatively with $L^*$- and $b^*$-value. Sensory firmness correlated positively with mechanically measured firmness.
