  • Physicochemical and sensory characteristics of Yukwa(fried rice cookie) made by different processing condition were investigated to estabilish the optimum expansion of Yukwa. The expansion rate and crispness of Yukwa prepared by soaking waxy rice for 24 hours was satisfactory . Addition of 15% soy slurry gave better effect on increasing the expantion rate, crispiness and sensory preference than no addition of soy slurry . Yeast, Soju(distilled liquor) , Mackeali(rice wine, turbid) and Chunju(rice wine, clear) as expansion reagent were added to Yukwa prepration . Yeast and Mackeali among tested expansion reagent showed better expansion rate and lower hardness meausred by texturometer than Chunju. Yukwa added chungju showed more fine structure and lower expantion rate than others. Microwave puffed Yukwa was less expansion rate, but same level of crispiness and hardness compared with oil puffed. And no difference in sensory characteristics such as degree of crispiness and stickiness of microwave puffed and oil puffed.

  • This study attempted to improve frying powder products based on 272 consumers' purchase conditions. Factor analysis by type was conducted on purchase attributes of consumers who purchased frying powder by categorizing them based on five factors-namely, convenience, information, diversity, safety, and economy. Five main factors were divided into four purchase attributes named various pursuit, convenience pursuit, economical pursuit, and inform/safety pursuit. Purchasing status of frying powder products was analyzed according to three independent variables such as age, meal preparation type, and purchase attributes. The top motivation for using frying powder was convenience. According to the importance-satisfaction analysis survey, taste, expiration date, and certification mark were chosen as highly important and high satisfaction characteristics for frying powder (p<0.001), whereas nutrition, oil absorption, adhesiveness, crispiness, origin, and food additives were highly important and low satisfaction characteristics (p<0.001). In the conjoint analysis, crispiness was the most important attribute of fried food.

  • In this study, when we reflect the preference of consumers who wish to receive their health through natural materials, and whose purpose is to receive good quality and good tasting cookies made from ginger. After 0%, 2%, 4%, 6%, 8% of flour was replaced by ginger powder for making cookies, a comparative analysis of quality characteristics and QDA was completed. Adding ginger powder caused a decrease in the density of the cookie dough, moisture content, loss rate and leavening rate of cookie (p<0.05), but the hardness of the ginger cookie increased. As a result of the description analysis of adding ginger powder, adding ginger powder increases, cookie color, crispiness, acid taste, flavor, and an after taste, but not the sweetness of the cookie. In terms of cookie color, crispiness, taste, flavor and overall acceptability, adding 4% ginger powder received high reviews. Also as a result of measuring DPPH radical elimination, ginger powder shows to have good antioxidant activity. So their anti-cancer activity is better than cookies without ginger powder. Therefore, we expect that we can fulfill the overall acceptability.

  • In this experiment, I used three samples of oils. The oils that I used were hydrated soybean oil, pure soybean oil and regular soybean oil. The group of rice was fried in the each sample of oil that had not been used for a few seconds. Rice was used after frying at 230-235$^{\circ}C$ every four hours terms and total frying hours was 12 hours. The hydrated soybean oils was least affected in rancidity. The other two oils were more affected in rancidity than the hydrated soybean oil. However, the trans fatty acid in hydrated soybean oil was 36.5%. The diameter of the poped rice that was fried in pure soybean oil and regular soybean oil that had been used 12 for hours was reduced while the diameter of the popped rice fried in the hydrated soybean oil was not reduced. Also, the groups of rice fried in the pure and the regular soybean oil that had been used for 12 hours reduced the hardness in rice while the group that fried in the hydrated soybean oil at the 12th hour kept the hardness well. In sensory evaluation, rancidity order was found apparently in the pure soybean oil that had been used for 12 hour and in the regular soybean oil that have been used for eight hours and 12 hours. Only the hydrated soybean oil did not have distinctive rancidity order at all. The degree of the crispiness was reduced in the pure soybean oil and in the regular soybean oil at 12th hour frying. However, the hydrated soybean oil preserved the crispiness well until the end of 12 hours of frying. In overall preference test, the pure and regular soybean oil that had been used for 12 hour were not preferable. In conclusion, I found that the group fried in the hydrated soybean oil was better in every evaluation than the groups fried in the pure soybean oil and in regular soybean oil. The hydrated Soybean oil may be better to be used in food manufacturing if the trans fatty acid in the hydrated soybean oil can be reduced.

  • 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.

  • This study was conducted to determine the reasonable soaking period of glutinous rice for laver Bugak (Korean traditional fried dishes) processing and to identify the sensory characteristics of three kinds of laver Bugak made with different starch pastes: GRice_1d using glutinous rice soaked for 1 day; GRice_7d using glutinous rice fermented for 7 days; and Wheat using flour. Descriptive analysis was performed by 10 trained panelists, and the 92 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. From the measurement result by scanning electron microscope (SEM), there were differences in the surface characteristics among soaking period for 1 day and 7 days. Ten panelists were trained, and they evaluated the appearance, odor/aroma, flavor/taste, texture/mouth feel, and after taste attributes of these samples. 36 attributes were generated by panelists and 12 attribute were significantly different across products (p<0.05). It was found that the Grice_7d sample was characterized by mouthfeel of crispiness and uniformity of bubbles, and the Wheat sample was characterized by surface of roughness, mouthfeel of crispiness and adhesiveness, relatively. And the Grice_1d sample was characterized by surface of roughness, mouthfeel of roughness, hardness, cohesiveness, toughness, and adhesiveness.
