  • The effects of baking with broccoli powder on the consumer perception and sensory characteristics were investigated using a model system of cookies incorporated with broccoli powder as a value-added food ingredient. Broccoli powder was incorporated into cookie dough at 5 levels (0%, 1%, 2%, 3%, and 4%, w/w) by replacing equivalent amount of wheat flour of the cookie dough. After aging and sheeting, cookies were baked at $170^{\circ}C$ for 8 min in an oven. The baked cookies were cooled to room temperature for 1 hour and packed in airtight bags prior to all measurements. Control received the most favorable mean score, which was not significantly different from samples with 1% broccoli powder for color preference (p>0.05). Results of the consumer preference on taste showed a similar trend. Consumers did not find any significant differences on aftertaste and flavor among samples prepared by replacing wheat flour with up to 2% broccoli powder (p>0.05). Overall, incorporation of 1% broccoli powder in the formulation would result in the most favorable broccoli cookies for the consumers without sacrificing the sensory qualities, while still taking advantages of health benefits of broccoli. Correlation analysis indicated that broccoli powder concentration was significantly negatively correlated with the consumer preference for color, taste, aftertaste, flavor, overall acceptability and positively correlated with sensory color, taste, and flavor (p<0.05). Consumers' color, taste, aftertaste, and flavor were well correlated with the overall acceptability (p<0.05). Sensory intensity results are also presented.

  • Effects of onion peel (OP) components (quercetin and rutin) in press ham on TBARS, pH, redness (a*) and flavor (panel test) were investigated during cold storage. TBARS in OP samples of high concentration was significantly (P〈0.05) lower than control during cold storage. This result suggests that OP components have an antioxidant activity in press ham. Also, redness of OP samples was significantly (P〈0.05) higher than control after three weeks of cold storage. Cured ham redness could be improved through lower pH of OP samples compared to that of control. However, flavor score of OP samples was not significantly (P〉0.05) different with control during cold storage. It could be possible that OP components plays role as an antioxidant without any negative effects on plavor of press ham. 양파 껍질을 급여한 돼지로부터 quercetin 및 rutin을 축적시킨 돈육을 원료육으로 하여 제조한 햄을 4주 동안 냉장 저장하면서 지방산패도(TBARS), pH, 육색(적색도) 및 향미의 변화를 조사하였다. TBARS의 경우 저장 3주부터 양파부산물 급여량이 높은 처리구가 유의적으로(P〈0.05) 낮은 수치를 보여 양파 껍질 성분의 항상화 효과가 인정되었다. 또한 저당 3주이후 대조구와 비교해 처리구가 유의적으로 (P〈0.05) 높은 적색도를 나타내었다. 이러한 결과는 양파 껍질 성분이 육제품의 변색을 억제할 수 있을 것으로 사료된다. 처리구의 염지 육색이 증진된 것은 처리구의 pH가 대조구에 비해 상대적으로 낮은 것으로 설명되었다. 한편, 향미의 관능검사 결과 처리구와 대조구 사이에 유의적인 차이는 인정되지 않았는데(P〉0.05), 이는 양파 껍질 성분의 항상화제로서의 역할과 향미에 미치는 영향이 다소 미미하였기 때문으로 사료된다.

  • In order to verify the quality characteristics of soybean milk added chickpeas, the following characteristics were investigated: pH, solid contents, color, DPPH radical scavenging, as well as electric nose and sensory evaluation. Physicochemical and the sensory characteristics were analyzed based on the experimental data. The pH value was different in the control and the treatments (p<0.005). As the quantity of chickpea content increased, the solid content was augmented (p<0.0001). The L value was 56.86 in the control, and with the amount of chickpea addition increasing, the L value increased to 57.43 in 100% chickpea soybean milk (p<0.0001). The a value and b value also increased significantly (p<0.0001). However, the DPPH radical scavenging in the control was the lowest but the antioxidant activity of 100% chickpea milk was more than 2.5 higher than that of the control (p<0.0001). In the electric nose experiment, the flavor component of 20%, 30% and 100% chickpea treatment showed a significant difference compared to the control in the flavor components. In the sensory evaluation, for the score of flavor (p<0.001) and taste (p<0.0001), the score was higher in the treatments where 20% and 30% of chickpeas were added. In the sensory test of texture, there was no significant difference in the different experimental conditions except for the 100% chickpea addition treatment. In the overall acceptability test, the scores of 20% and 30% chickpea treatment were the highest results, compared to other treatments (p<0.0001). According to the correlation analysis, both antioxidant activity (0.797) and solid content (0.834) had shown high correlation to pH among the physiochemical characteristics (p<0.01). In the sensory evaluation, color, flavor, taste, texture and overall acceptability had shown a positive correlation to the amount of the soy bean milk added chickpea (p<0.01). In particular, the overall acceptability had shown the highest correlation to the taste (0.803), and it was the texture which resulted in the next highest correlation for overall acceptability (0.666).

  • The principal objective of this study was to evaluate the quality characteristics of jelly prepared with five different levels(0, 0.5, 1.0, 1.5, and 2.0%) of black garlic concentrate(BG1-BG4). We conducted the pH, sugar content, Hunter's color value, mechanical characteristics, and a sensory evaluation analysis of black garlic jelly. The more black garlic concentrate increased, the more the sugar content of the black garlic jelly increased(p<0.05). In terms of color, lightness(L) and yellowness(b) decreased as the black garlic concentrate increased, while redness(a) increased. With regard to the mechanical properties of the black garlic jelly samples, the higher the score of hardness, gumminess, and chewiness significantly increased(p<0.05). In color, flavor, texture and overall quality, the score of jelly with 1.0% black garlic concentrate(BG2) increased most of the all.

  • This study aimed to find oils that can replace high-priced sesame oil. The quality of baked Yackwa containing different types of oils (rice bran, olive, or sesame oils) and amount of oils (30, 35, 40%) were investigated. The hardness of the baked Yackwa depended on the amount of oil, as more oil led to a softer texture of baked Yackwa. According to sensory evaluations, baked Yackwa with rice bran oil received the highest score in taste quality, with sesame oil receiving the second highest score. The flavor of baked Yackwa containing the rice bran oil was also better than other samples. In contrast, there were no significant differences in taste between other samples, including baked Yackwa containing all ingredients, 40% sesame oil, and 40% olive oil. The overall acceptance showed the highest score in baked Yackwa with rice bran oil (35%). In conclusion, rice bran oil (35%) is recommended as an oil ingredient for baked Yackwa.

  • Glutinous rice dduk, traditional Korean rice cake, was prepared using rice(white glutinous rice, brown glutinous rice, black glutinous rice, gaba glutinous rice) as a meal alternative, and each of their quality characteristics were compared. This study had checked sensory tests, color differences, moisture contents, texture characteristics, and storage lives of dduk during storage at room temperature for 6 days. The moisture contents of black glutinous rice dduk scored the highest. For color properties, gaba glutinous rice dduk was darker with a decreased yellow value, whereas its red value was higher comparing with that of brown glutinous rice dduk. The results of the preference test showed that appearance, flavor, texture, and overall preference were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the lowest score. The results of the color difference test showed that softness, viscoelasticity, and fineness were the highest in white glutinous rice dduk, whereas black glutinous rice dduk showed the highest difference in color. For individual textural characteristics, black glutinous rice dduk showed the highest score, whereas white glutinous rice dduk showed the lowest scores in hardness, chewiness, and gumminess. In the results of the textural characteristics of dduk during storage, white glutinous rice dduk showed the highest increase in hardness after 48 hours, whereas black glutinous rice dduk showed the lowest increase. White glutinous rice dduk showed the highest increases in chewiness and gumminess. Cohesiveness decreased in all glutinous rice dduk. In the results of fungal occurrence in dduk during storage, black and gaba glutinous rice dduk showed increased fungi occurrence compared with white and brown glutinous rice dduk after 6 days. In conclusion, the overall preference for glutinous rice dduk made from different rice is more affected by appearance or texture than flavor.
