  • This study was conducted to examine the sensory attributes, gingerol content and volatile components of ginger paste resulting from microbial fermentation. In the ginger samples, a total of eighteen attributes were determined to characterize the sensory attributes from descriptive analysis. These eighteen attributes consisted of the following: one appearance, eight odor/aroma, eight taste, and one aftertaste attribute. The ginger fermented using Lactobacillus plantarum produced a ginger aroma and putrid taste, whereas the sample fermented with Lactobacillus brevis showed a decreased ginger aroma and taste, and generated a lemon flavor. A total gingerol content of fresh and fermented ginger was 100.19 mg% and 89.55 mg%, respectively. Sixty-one volatile components in the fresh and fermented ginger were identified, and constituted eight kinds of monoterpenes, twenty-one kinds of sesquiterpenes, eight kinds of oxygenated monoterpenes and nine kinds of oxygenated sesquiterpenes. The most abundant volatile component identified in the fresh ginger was $\alpha$-gingerberine (26.52%), whereas fermented ginger was increased in its alcohol components.

  • Soybean rice cake, which is often used in Hamkyungdo, is well hewn for a good taste and the slow firiming rate. Since soybean rice cake may taste different according to the amount of ingredients, this study will make a test of the taste and properties of two groups of soybean rice cake. One is prepared from rice flour mixed with yellow soybean and peanut flour at several rate, and the other is prepared from rice flour mixed with oil extracted from yellow soybean and peanut, the containing amount of which is the same as that of oil ingredient contained in each flour. Rice cake prepared mixed with extracted soybean oil shows better characteristics than that which is prepared mixed with soybean flour containing the same amount of oil. The result by sensory test reveals that the element which has a great influence on soybean rice cake is oil. Prepared mixed with extracted oil, soybean rice cake tastes best at 6% of oil, while rice cake prepared mixed with flour instead of oil tastes best at 8% of flour. As this study shows that the relation between firiming rate and oil has a significant influence on cohesiveness, moistness, and chewiness, it is needed to further study the effect of oil according to the kinds of the flour of rice or other grains used.

  • This study was done to provide the basic information of bread made with curry powder. The amounts of curry powder used were 0 to 3% based on the wheat flour weight. The quality of bread was investigated by evaluation of the specific loaf volume, water absorption capacity, color, sensory quality and texture. The weight of bread decreased with the increase of curry power contents, but there were no significant differences among 0.5, 1 and 2% added curry powder bread. The volume and specific loaf volume also decreased with the increase of curry power contents, but those decreases were not significant between 1% one and 2% one. The water absorption capacities were not affected by the addition of curry powder. The lightness and redness decreased with an increase of curry powder content in the bread, while yellowness increased significantly(p<0.01). The result of the sensory evaluation showed that total acceptabilities of appearance, aroma, texture and taste in the bread with 0.5% and 1% curry powder were significantly higher than the control group and the other groups. Overall quality was negatively affected by the yellowness, odor, hot and bite taste of added curry powder. The factors affecting on the overall quality of the bread with added curry powder were in order of taste quality > curry powder odor > texture quality > aroma quality > springiness > wheat flour odor.

  • Aronia melanocarpa (black chokeberry) powder containing various bioactive compounds is widely used in the food industry. We examined the sensory attributes (taste, color, flavor, texture, and overall acceptability) of market milk, yogurt, and Kefir containing different concentrations of Aronia melanocarpa powder. In market milk, the scores of all categories except color were the same or lower in market milk containing 0.5%, 1.0%, 1.5%, or 2% Aronia melanocarpa powder than the control group (0%). No statistical difference in color and flavor was observed between Kefir and yogurt. However, there was a statistical difference between the control and treated groups in taste, texture and, overall acceptability (p<0.05). As the content of Aronia melanocarpa powder increased, color, flavor, taste, and overall acceptability scores generally decreased. Yogurt and Kefir, with the addition of 1% Aronia melanocarpa powder, displayed the highest scores.

  • In this study, we investigated the effects of sweeteners on the quality of Kakdugi through the addition of 1.8% sugar, 0.006% sodium saccharin or 0.006% stevioside using a physicochemical test and sensory evaluation during fermentation at $20^{\circ}C$. The addition of sugar to Kakdugi resulted in the lowest pH and the highest total acidity relative to the control and experimental groups during the fermentation period. The number of lactic acid microorganism gradually increased and then decreased. The sensory evaluation revealed that the addition of sodium saccharin to Kakdugi resulted in the highest sweet smell and taste followed by the addition of stevioside. The addition of sodium saccharin to Kakdugi showed the highest sweet taste and the best texture, and the sweetness compensated for the sour smell and taste.

  • Pine mushroom is excellent for its unique smell, nutrients and functional factors. The quality characteristics of Demi-glace sauce made from pine mushrooms that have not been used despite their value as good ingredients and mushrooms that have been added to various kinds of sauce were examined by differing pine mushroom and mushroom powder in stock. The more pine mushroom and mushroom powder was added, the content of minerals increased; however, the content of moisture decreased. Overall, viscosity was increased. The content of each mineral varied in proportion to pine mushroom and mushroom powder contents level. Sensory evaluation of pine mushroom added to demi-glace sauce showed difference in sweetness, savory taste overall. 0.2% addition of sweetness, 0.3% addition of savory taste, 0.2% and 0.3% addition of overall acceptability appeared as the best estimation. Specially, 0.2% addition was the highest in salty taste and color. As the two mushroom powder contents was increased, tastes of demi-glace sauce were not increased; rather, the appropriate amount of addition existed.

  • This study was carried out to determine the best mixing ratio of French dressing containing onion juice which was added at with different levels (12, 24, 36, and 48%). The mixing methods of ingredients were evaluated through sensory evaluation and viscosity and color of were measured. Instead of soy bean oil, we also studied various oils(corn oil, grape seed oil, canola oil, and olive oil) for the purpose of determining functional French dressing. The results were as follows; The results of the sensory evaluation showed that the French dressing with 36% added with 36% onion juice was the preferred most in appearance, flavor, and overall preference. Correlation coefficients between overall preference and sensory characteristics of onion added French dressing were higher in the order of taste (r=0.64), flavor (r=0.54), texture (r=0.48), appearance (r=0.41). The quality of French dressing varied greatly depending on the mixing methods of ingredients. The best method for making dressing was mixing 5 mL of oil with the other ingredients at 5 seconds intervals. The results of the sensory evaluation on French dressings with added onion juice containing soybean oil, corn oil, grape seed oil, canola oil, and olive oil, indicated that soybean oil was the most preferable. The appearance and taste of French dressing containing soybean oil were significantly the highest with regard to preference.

  • Coffee beans are processed from coffee cherries by either natural, pulped natural, or washing. The aim of the present study was to evaluate the physiochemical and sensory characteristics of espresso coffees processed by different methods. The color of the washed coffee sample presented the highest value of lightness while the natural coffee sample presented the highest value of redness and yellowness. The biggest difference in brewed coffee, whether natural, pulped natural, or washed, was in the TDS content, which was higher in natural coffee and lower in washed coffee. Sensory descriptive analysis and acceptance test for espresso coffee using a 15 cm line scale were carried out by 12 trained panelists. Natural coffee had the highest cherry-like flavor and sweetness taste while washed coffee had the highest citrus flavor and acidity taste. An important attribute of espresso coffee is body, and natural coffee presented strong body while washed coffee presented a low body attribute. In conclusion, significant differences were observed among the three processing methods of green coffee. Pulped natural coffees presented intermediate physiochemical and sensory characteristics compared to washed and natural coffee. Natural coffees are appreciated for their increased body, and washed coffees are appreciated for added citrus flavors and acidity espresso coffee blends.

  • The study explores the sensory properties of Backsulgi prepared with dry non-glutinous rice flour sweetened with various sweeteners(sugar, honey, oligosaccharide, trehalos, erythritol and accesulfame K). Sensory attributes of Backsulgi were evaluated by quantitative descriptive analysis(QDA), PCA and PLSR. The QDA results revealed that the sample sweetened with trehalose showed highest value in dryness, and samples with accesulfame K, honey and erythriol had relatively high levels in moisture and springiness. Principle component analysis (PCA) results showed 78.89 % of the total variation with PC1 (54.92%) and PC2 (23.98%), respectively. The samples with accesulfame K(AF) and honey, which showed high values in moisture level, springiness and sweet taste, showed similar attributes which led to a positive direction of PC1. The correlation between the sensory attributes and consumer acceptance showed that the most important factors for high consumer acceptance were moistness, springiness, sweet taste and sweet flavor. Overall, the samples with accesulfame K(AF) had the closest position in the PLSR results with highest overall consumer satisfaction.
