The quality characteristics of Korean rice cakes (Karedduk) with a mixture of fructooligosaccharide (95%) and AA (acetylated adipate distarch) added, after 2 and 24 hours of storage at $5^{\circ}C$, were investigated. A central composite design was used for arrangement of treatment. Different levels of fructooligosaccharide (95%), 0, 3, 6, 9, and 12%, were added to dry rice flour. In addition, different levels of AA, 0, 0.3, 0.6, 0.9, and 1.2%, were added to the same dry rice flour. The texture properties analysis using a Texture Analyzer revealed that the springiness, cohesiveness, chewiness, gumminess, adhesiveness, and hardness were significantly different. The effect of retarding retrogradation of Korean rice cakes (Karedduk) with added mixtures of fructooligosaccharide (95%) and AA showed an increasing trend as the amount of fructooligosaccharide (95%) and AA increased. Overall, the instrumental texture properties were highly correlated with the sensory characteristics. These results suggest that adding a mixture of 6% fructooligosaccharide (95%) and 1.2% AA to Korean rice cakes (Karedduk) is effective for retarding retrogradation.

물김치는 발효 중 국물에 생성된 젖산을 비롯한 각종 유기산과 이산화탄소가 주는 독특한 신선미와 상쾌한 탄산미 그리고 배추나 무의 아삭아삭한 조직감 때문에 즐겨 먹는 김치의 종류이다. 일반 배추로 담근 물김치가 무색인데 비해, 안토시아닌 색소를 함유한 자색 양배추를 주재료로 물김치를 담그면 발효됨에 따라 유기산이 생성되어 pH가 낮아짐에 따라 색소가 안정화되어 시각적으로 아름다운 색을 띌 것으로 생각된다. 따라서 본 실험에서는 배추, 흰양배추, 적색양배추로 물김치를 담그어 숙성되는 동안의 이화학적, 관능적 특성을 분석하였다.

The purpose of this study was to develop a muffin recipe that included germinated brown rice powder soaked in a mycelial culture broth of Phellinus linteus (GBRP). Muffins were made using various quantities of GBRP, butter, and milk. An assessment was conducted using the response surface methodology (RSM), which included 16 experimental points with three replicates for the three independent variables: GBRP, butter, and milk. The physical and chemical evaluation using the RSM showed no significant differences; whereas the hardness, cohesiveness, springiness, gumminess, and chewiness indicated significant differences in the relationships between the factors (p<0.05). The sensory evaluation using the RSM was highly effective in describing the relationships between overall acceptability and taste (p<0.001). Thus, the optimal combination of ingredients in a GBRP muffin, as assessed with numerical and graphical methods, was 84.041 g GBRP, 110.224 g butter, and 80.0 g milk.

Jeungpyun was prepared with different ratios of makkulli leaven to water in order to examine the changes in its quality characteristics. The results on the height and volume of the samples showed that Jeungpykn prepared with the ratio of 1 makkulli leaven to 2 water showed the highest degree of fermentation. Texture profile analysis, Hunter's color and sensory evaluation of jeungpyun were carried out for 4 days from the day of its steaming, to see its quality changes. In texture profile analysis, the hardness, gumminess and chewiness increased in all samples as the time elapsed, and at the same time texture parameters were increased as the water ratio increased. As the water ratio increased, L value was increased; however, a value and b value were decreased. The results of sensory evaluation showed that Jeungpyun prepared with the ratio of 1 makkulli leaven to 2 water had the most favorable sensory qualities.

Response surface methodology (RSM) was used to monitor extraction characteristics of electron donating ability and organoleptic properties for ethanol extracts from Chrysanthemum petals, thereby determining optimum extraction conditions. A central composite design was applied to investigate effects of solvent per sample $(X_1)$, ethanol concentration $(X_2)$ and extraction time $(X_3)\;at\;60^{\circ}C$ on dependent variables such as electron donating ability $(Y_1)$, organoleptic color $(Y_2)$ and organoleptic aroma $(Y_3)$ of the extracts. Second-order models were employed to generate 4-dimensional response surfaces for qualitative and quantitative aspects of ethanol extracts. Coefficients of determination $(R_2)$ of the models for dependent variables were ranged from 0.8180 to 0.9696. Optimum extraction conditions for each variable were 50 mL/g, 61% and 16 hrs in electron donating ability, 88 mL/g, 21% and 16 hrs in organoleptic color, 55 mL/g, 73% and 19 hrs in organoleptic aroma, respectively. The optimum condition ranges for maximized characteristics of ethanol extracts were $65{\sim}78\;mL/g,\;90{\sim}100%\;and\;15{\sim}25\;hrs$. Predicted values at the optimum conditions were in good agreement with experimental values.

The purpose of this study was to investigate the sensory characteristics of 11 noodles from four countries by descriptive analysis and consumer acceptance test. Noodle types were udon, pasta, kalguksu, and plain noodles. Fourteen sensory descriptors were developed to evaluate the sensory characteristics of the noodles. The sensory characteristics of the noodles were sweetness, saltiness, springiness, hardness, chewiness, milk flavor, yeasty odor, milk powder flavor, loose particles, and so on. PCA conducted to visually summarize the sensory characteristics of noodles by consumer preference test revealed that 77.1% of the variance was positively defined by sweet, springiness, cohesiveness, chewiness, and moisture and was negatively defined by hardness, color, and floury taste. Yk_udng_KR, thin_KR showed high scores for attributes of springiness and cohesiveness. Overall consumer acceptance was surveyed. Udng_KR scored the highest for attributes such as gusu. Udng_KR showed the highest springiness and high moisture, taste acceptance, and overall acceptance. Note: Please confirm this word.

The effects of different dehydration conditions for the removal of ginkgo nut inner coat on peeled ginkgo nuts were examined using physical and sensory methods. Dehydration of ginkgo nuts at $90^{\circ}C$ for 120 min resulted in greater hardness, lightness (L), redness (a), yellowness (b), and firmness. Higher roasted flavor and larger holes were observed with dehydration at $150^{\circ}C$ for 30 min and greater cooked ginkgo flavor and green color with dehydration at $120^{\circ}C$ for 50 min. Based on these findings, dehydration at $120^{\circ}C$ for 50 min was determined as the adequate hot air dehydration condition for the removal of ginkgo nut inner coat. Ginkgo nuts stored at $25^{\circ}C$ maintained overall desirability up to 4 weeks. In ginkgo nuts stored at $4^{\circ}C$, all sensory desirabilities evaluated were reasonably high until 60 days of storage; desirability of appearance decreased moderately at 80 days of storage, and appearance became very undesirable at 180 days. Ginkgo nuts stored at $-18^{\circ}C$ showed little changes until 10 months of storage, but slight decreases in overall desirability, flavor, and texture were noted at 12 months.
