This study was conducted to examine the physicochemical properties and consumer acceptability of commercial Gang-jeong. The samples used in this study were nine different Gang-jeong as commercial products. To accomplish this research, the physicochemical properties of nine samples, including moisture, crude lipid, sugar contents, acid value, color values, and texture, were measured. In addition, consumer panels evaluated the overall acceptability, appearance, flavor, sweetness, and texture of samples using a 9-point Likert type scale as well as the perceived intensities of sweetness and rancid odor by a 9-point Just-About-Right (JAR) scale. All data were statistically analyzed using One-way ANOVA, Principle Component Analysis, Hierarchical Cluster Analysis, and Pearson's Correlation Analysis. All physicochemical properties were significantly different among the samples (p<0.001). Analyses of consumer acceptability and JAR ratings of the nine samples showed significant differences (p<0.001).

This study was performed to examine attitude, perception, and sensory evaluation of Jjigae HMR (Home Meal Replacement) for Americans in the L.A. area. Attitude and perception of Jjigae were conducted by 128 consumers. The questions were as follows: 1) frequencies and attitude toward soup and stew, 2) experience and frequency of Korean food intake, 3) awareness of Korean Jjigae. A total of 69.5% of American had previous experience with Korean foods. However, the frequencies of Korean food intake were once every few months (27.4%) or once a year (18.9%). The 20.2% of consumers selected Kimchi-jjigae as the best-known Korean Jjigae, and 17.1% of consumers had previous experience with Kimchi-jjigae. However, the 23.7% of consumers did not have experienced with Jjigae. Sensory evaluation was conducted using Sundubu-jjigae and Kimchi jjigae. Overall liking and flavor liking were conducted by Americans using a nine-point scale (1: Dislike extremely - 9: Like extremely). The degree of intensity for sensory attribute was also rated using a nine-point Just-About-Right(JAR) scale (1: not nearly spicy/sour enough, 5: Just-About-Right, 9: too spicy/sour). Purchasing intention was rated using a five-point scale (1: Definitely would not purchase, 5: Definitely would purchase). Overall liking and flavor liking of two jjigae (Sundubu-jjigae & Kimchi-jjigae) had a value higher than five on the nine-point scale. The level of spiciness of Sundubu-jjigae was suitable for consumers whereas spiciness of Kimchi-jjigae was significantly different from the JAR value of five points on the nine-point JAR scale, showing that Kimchi-jjigae was significantly spicier than JAR point. Purchasing intention had a value higher than three on the five-point scale.

This study was performed to analyze the JAR (Just-About-Right) Rating and CATA (Check-All-That-Apply) Method for commercial Yugwa (Korean oil pastry products) containing Baeknyeoncho (Opuntia ficus-indica var. saboten). The survey was conducted with 50 participants, and five kinds of Yugwa samples (Control, B-YG, B-RY, B-WY and B-GB) were used. According to the results of the study with these samples, the B-RY sample received the highest score in 'Try again (6.30/9)' and 'Recommend (6.24/9)'. The Control Sample, which was the traditional Yugwa, received the second highest score (Try again: 5.62/9, Recommend: 5.70/9). The liking attributes for these samples were related to eating convenience, familiar taste, traditional type and size. These findings suggest that the factors to be considered in the development of commercial Yugwa are the maintenance of traditional taste and familiarity in an easy-to-eat size for consumers.

국내 주요 복분자 산지인 고창, 정읍, 횡성, 순창산 복분자로 복분자주를 제조하여 제조 복분자주의 휘발성 향기성분 분석과 기호도 조사를 통해 산지별 차이를 파악하였다. 복분자주의 주요 향기성분으로 phenylethyl alcohol, isoamyl alcohol, diethyl succinate, isobutyl alcohol, acetic acid, octanoic acid, benzoic acid, $\alpha$-terpineol, myrtenol, pcymene-8-ol이 동정되었고 특히 적포도주에 비해 terpene류가 많이 검출되어 복분자주의 odor-active compounds를 분석하기 위해 gas-chromatography-olfactometry를 포함한 다양한 향기성분 분석 연구가 필요한 것으로 보인다. Ester류는 횡성산과 정읍산 복분자주에서 많이 검출되었고 alcohol과 acid류도 횡성산에서 가장 많은 농도를 나타내었다. Terpene류는 정읍산에서 가장 높게 나타났다. 차후 이들 시료에 대한 묘사분석을 통해 향기성분과의 상관관계 분석이 필요하리라 여겨진다. 전반적인 기호도에서는 제조복분자주에서 고창, 순창, 횡성, 정읍순으로 나타났고 특히 횡성과 정읍 시료의 경우 단맛은 약하고 신맛은 너무 강한 것으로 나타나 당산비 조절이 필요한 것으로 여겨진다.

This research evaluated and analyzed the level of acceptability of spinach according to blanching time by testing consumer taste of corresponding countries for the purpose of globalizing Korean food. General taste, appearance, flavor, and texture of spinach blanched for 20 seconds were highly evaluated by Koreans and Japanese ($p$<0.05), who are used to the method of slightly blanching, mixing, and eating spinach. On the other hand, general taste, appearance, flavor, and texture of spinach blanched for 5 minutes was highly evaluated by the French ($p$<0.05), who are used to eating boiled spinach. Concerning the result of JAR, there were clear differences in hardness and boiling level according to country among spinach samples, even though they were blanched for the same time and mixed with the same spices. Koreans and Japanese evaluated that hardness and boiling level of spinach blanched for 20 seconds were proper, whereas the French evaluated that spinach scalded for 20 seconds was too raw and crispy. Under the same context, French consumers evaluated that hardness and boiling level of spinach blanched for 5 minutes was proper, whereas Koreans and Japanese evaluated that spinach blanched for 5 minutes was boiled too much. These results show that familiarity level is an important driver of affecting the preference levels for three kinds of spinach according to country.

This study was conducted to identify the sensory characteristics of four kinds of wild vegetables (samnamul, miyeokchwi, daraesoon and bangpung namul), which were prepared through three different soaking methods: SBS (soaking both before and after boiling), BS (soaking only after boiling) and B (never soaking). Moreover, it also compared the consumer acceptance of these samples in Korea. A descriptive analysis was performed on 12 samples (Sam_SBS, Sam_BS, Sam_B, Miyeokchwi_SBS, Miyeokchwi_BS, Miyeokchwi_B, Daraesoon_SBS, Daraesoon_BS, Daraesoon_B, Bangpung_SBS, Bangpung_BS and Bangpung_B) by 10 trained panelists. Furthermore, 115 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale; they also rated the perceived intensities of toughness, roughness and moistness using a 9-point just-about-right (JAR) scale. According to the results of the PLSR data, the Sam_SBS sample, which had significantly (p<0.05) high muddiness, moistness, brightness, redness, oily appearance, sesame oil flavor, softness and greasy attribute scores, presented the highest acceptability and consumer desire scores for consumers. On the other hand, the Miyeokchwi_B and Bangpung_B samples, which had relatively high toughness, crispiness, roughness, bitterness and, astringent attributes scores, were the least preferred samples. Therefore, the muddiness, moistness, brightness, oily appearance, sesame oil flavor, softness and greasy attributes were drivers of "liking," whereas toughness, crispiness, roughness, bitterness, astringent attributes acted as drivers of "disliking" for consumers.
