  • This study was analyzed to the components of leaf teas produced by manufature methods for which estimated food and nutritional values of Lindera obtusiloba loaves growed in Korea and had unique taste and aroma. There were identified to four kinds of free sugars in Lindera obtusiloba leaf teas and its content was the highest in the roasted tea among others. The contents of glutamic acid, aspartic acid, asparagine, and glycine were remarkably higher than other amino acids. The contentsof free amino acid in the leased tea and the androasted tea after steaming wase. 6 mg/100g had 101.5 mg/100g, respectively,had especially higher than in the others. Among the amino acid derivativer, phosphoserine, ${\alpha}$-aminobutyric acid, ${\beta}$-aminobutvic acid, and anserine contents were especially higher than others, but were not significantly difference by the manufacturing process. The volatile organic acids were composed acetic, propionic and butyric acid, and the nenvolatility organic acid were composed citric, oxalic, levulinic glutaric, lactic and pyroglutamic acid.

  • Eel is Anguilla japonica and Anguillidae family as a freshwater fish, and Japanese name is Unagi. The content of vitamin A of eel muscle are about 4,000IU/100g and they have many effective components, so it is known as healthy food. Therefore, many people have eel that cooked roast and hot-water extract in Korea. WHO encouraged that daily edible content of vitamin A is 2,000IU. Now, Japan government proposes the weight of roasted eel in lunch basket as 50g. But, Korea government does not proposes in every related aspects. Therefore, we researched content of vitamin A in hot-water extract from eel and optimal processing condition of hot-water extract from eel, in order to determine a proper edible volume. The content of vitamin A in eel hot-water extract sold at a market was about 200 IU. This study resulted from the fact that many eel hot-water extracts lacked the vitamin A. The reason was that the lipids were removed for taste on processing. But, The content of vitamin A in eel hot-water extract which didn't removed lipid on processing was about 800IU. Therefore, in drinking for 3packs per day, eel hot-water extract might have adjusted 100mL per pack which is almost consistent with the recommended dietary allowance of vitamin A in WHO.

  • Objectives: This study was conducted to identify factors that influence the consumption of temple food and to find systematic methods improving the popularization of temple food. Methods: A self-administered questionnaire was applied to 304 temple food restaurant visitors, including 232 local and 72 foreign individuals. The questionnaire was designed to investigate recognition, consumption, preference and popularization of temple food among restaurant visitors. Results: The study population consisted of 30.6% men, 69.4% women. 76.3% were Korean while 23.7% were foreigners. The responses on their impression on temple food contained the words, "vegetarian" (4.64), "plain and familiar" (4.19), and "good for dieting" (4.16). The most commont reason to favor temple food was its "mild taste" (63.0%) in the local group while foreigners preferred it because it is "good for health" (35.8%). The preferred kind of side dish of the local group was roasted dish (4.40), stir-fried dish (4.39), blanched vegetables (4.36), and food boiled with sauce (4.23); foreigner's high preference was for stir-fried (4.67), Jangachi (4.63), food boiled with sauce (4.56), and Buggak (4.55).. Most respondents thought that it is necessary to maintain the traditional form of temple food. While 43.5 percent of Koreans responded that "the five pungent vegetables" could be allowed, 62.8 percent of foreign respondents said it is permissible. Conclusions: A systematic approach to improve the temple food that reflects both foreign and local preference while maintaining its originality is necessary for its globalization. Furthermore, restaurants specialized in temple food should be expanded and promoted through effective marketing strategies that would make the cuisine easily accessible and spread throughout the world.

  • The purpose of this study was to investigate the effects of demographic characteristics such as gender, marital status, age, educational level, job and monthly income on the preferred menu classified by type of food, food material, cooking method, taste and food temperature. A survey was performed from the 5th to 10th of January, 2013 among consumers in such places as coffee shops and subway stations located in Daegu and Gyeongbuk region, and finally 307 data sets were used for analysis. The results of analysis showed that the strongest effects of demographic characteristics were observed in preferred menu classified by type of food(i.e. Korean, Western, Chinese, Japanese, buffet, herbal and instant foods), and the differences by marital status, age, educational level, job were statistically significant. In particular, the married consumers tended to prefer Korean and herbal foods, while the unmarried ones preferred western, Chinese, buffet and instant food. Moreover, the younger ones tended to prefer western, Chinese, buffet and instant foods, while the older ones preferred to eat Korean food. The younger unmarried ones liked beef and pork dishes, while the married ones over their forties tended to prefer vegetable dishes. The consumers less than or equal to their thirties tended to prefer roasted and fried foods compared to ones over their thirties.

  • The purposes of this study are to generate sensory profile, measure consumer acceptance, and determine liking and disliking factors of aseptic-packaged rice porridges (APRP). Five APRPs made by five different rice cultivars were used for this study. Twenty-one attributes were generated by trained panelists. Finally, 16 attributes were determined as descriptive terms for APRP. Each cultivar showed a different descriptive sensory profile. In a consumer acceptance test, there was no statistical difference (P>0.05) in the acceptances of the overall, appearance, taste, texture, viscosity, and rice particle texture among the 5 APRPs. SW52 showed the highest acceptance ratings in the overall, appearance, taste and texture, followed by SR. A total of 52% of consumers showed preference toward SW52 and SR. SW63 showed the lowest ratings and no consumer preference pattern. Consumers were divided into two groups by a cluster analysis; one was the consumers (C1) who liked APRP, and the other was the consumers (C2) who had a neutral stand in general. By correlating the results from descriptive analysis and consumer ratings from C1, liking and disliking factors for consumer acceptance were determined. The disliking factors were bitterness, feeling of surface, stickiness, metallic flavor, roasted aroma, and thickness. The liking factors were old cooked rice aroma/flavor. The disliking factors dominated in the determination of acceptability of APRP. Selecting rice cultivars that had low intensities of disliking factors is the key for APRP development.

  • In a previous study, isoflavones showed prominent physiological effects on diabetes, hyperlipemia, and alcoholic hepatotoxicity. The purpose of this study was to develop isoflavone-rich bean sprout- and isoflavone extract-containing foods, to improve symptoms of diabetes and hyperlipemia. The foods employed were yogurt, bread, and cookies. Through sensory evaluations, the ingredient amounts were determined. In the sensory evaluations of the yogurt and bread, overall taste scores decreased with increasing amounts of bean sprout powder. However, for the cookies, the overall taste score increased with an increasing amount of bean sprout powder, and the addition of isoflavones had no influence on flavor. The results indicated the following ingredient levels for ultimate product development. For the yogurt, 100 mL of low fat milk was fermented at $50^{\circ}C$ for 36 hr, and mixed with 0.5 g of roasted bean sprout powder and 31 mg of isoflavone extract. For the bread, bean sprout powder was added to wheat flour at a replacement level of 10%, which was mixed with 12 g of butter and 124 mg of isoflavone extract for 200 g of dough. For the cookies, the bean sprout powder was added to wheat flour at a replacement level of 60%, and then mixed with 15 g of butter and 124 mg of isoflavone extract for 100 g of dough. The total isoflavone contents of the yogurt, bread, and cookies were 14.35 mg/100 mL, 38.24 mg/100 g, and 190.00 mg/100 g, respectively.

  • The purpose of this study was to compare the eating habit, food intake frequency and preferred food and taste of juvenile delinquents (100 numbers) and male high school students (100 numbers), using questionnaires from August to October 2004. 1) It was shown that the juvenile delinquents took more unbalanced diet (p<0.05), smoking (p<0.001) and drinking (p<0.001) than general students, while general students had more eating between meals (p<0.01). 2) The intake of food was a significant difference in white rices (p<0.01), bibimbab (p<0.001), kimbab (p<0.001), fried rice (p<0.001), ramen (p<0.001), jajangmyun (p<0.001), jambong (p<0.001), hamburger (p<0.001), pizza (p<0.001) and breads (p<0.05). The juvenile delinquents took more major food than that of general students in all the items except for white rice. It was observed, then, that the juvenile delinquents showed more intake of such subsidiary foods as bulgoki (p<0.001), roasted thin pork chops (p<0.001), grilled pork belly (p<0.001), pork cutlet (p<0.01), sweet and sour pork (p<0.001), chicken with ginseng (p<0.001), fried chicken (p<0.001), kimchi pot stew (p<0.01) and zucchini (p<0.05) than general students, with general students taking more kimchi (p<0.01) and fried or boiled soybean curd (p<0.01). The intake of dessert was a significant difference in yogurt (p<0.01), orange juice (p<0.001), cola (p<0.001), soft drinks (p<0.001), ion drinks (p<0.001), coffee (p<0.001), apple (p<0.01), banana (p<0.001), orange (p<0.001), cake (p<0.001), hot dog (p<0.001), ddokbokgi (p<0.01), mandu (p<0.001), fried fish paste (p<0.05), steamed korean sausage (p<0.001), fried foods (p<0.05), hem & sausage (p<0.001), cheese (p<0.001), ice-cream (p<0.001), candy (p<0.01), chocolate (p<0.001), mayonnaise (p<0.05), jam (p<0.01) and butter & margarine (p<0.01). Then, the juvenile delinquents were shown to entirely have more intake of all the desserts than those of general students. 3) Regarding preference of foods, it was shown that the juvenile delinquents preferred cereals (p<0.05), grilled pork belly (p<0.001), chicken with ginseng (p<0.01), anchovies and small fish (p<0.05), chicken with ginseng (p<0.05), seasoned spinach (p<0.001), seasoned zucchini (p<0.001), milk (p<0.05), coffee (p<0.001) and butter & margarine (p<0.05) while general students did egg (p<0.01), soybean sprout soup (p<0.001), boiled or fried potato (p<0.05), seasoned soybean sprout (p<0.05), boiled or fried soybean curd (p<0.01), fried foods (p<0.01) and snack (p<0.05). For their preference of tastes, hot taste (p<0.01) was higher in the juvenile delinquents. 4) Under general environments there was a change of the difference in their behaviour of pork cutlet (p<0.01) intake in accordance with other family and of milk (p<0.001) and butter & margarine (p<0.05) preference in accordance with growth in a big city between the two groups.

  • To evaluate the potential use of apricot as a sauce ingredient, the physicochemical and sensory characteristics of apricot brown sauce were compared. Various concentration (0%, 10%, 20%, 30%, 40%) of apricot were used to evaluate the quality characteristics of the sauce during storage for 12 days at $4^{\circ}C$. The pH value of the 5 types of brown sauce ranged from 3.8 to 4.6, and these pH levels were stable during the storage period. The L-values of the 0% apricot brown sauce were higher than those of the 10%, 20%, 30% and 40% apricot brown sauce. All the samples tended to have higher viscosities during storage, especially after three days after. In the sensory evaluation, softness, roasted flavor, texture, after taste, and overall taste were highest for the 10% and 20% apricot brown sauce. For the overall acceptability, the $10{\sim}20%$ apricot brown sauce attained the highest score.

  • The cytotoxicity of coffee-like green tea (CLGT) was determined in a human breast cancer cell line, MCF-7; a human prostate cancer cell clone, PC-3; a human neuroblastoma cell line, SK-N-SH; and a rat cardiomyoblast cell line, H9c2, with reference to green tea leaves (GTL). The CLGT was prepared by roasting the GTL for 60 min at $240^{\circ}C$ in a temperature-controlled frying pan. The CLGT preparation imitated the flavor and taste characteristics of coffee fairly well according to sensory analysis. The CLGT preparation had no adverse cytotoxic effects on the cancer cells or the normal cells compared to GTL. No significant change in the antioxidant activity was seen in the CLGT preparation compared to that of GTL. The amount of total protein, sugar, and phenolic compounds was reduced in the preparation relative to those in GTL, a fact that might explain the coffee-like flavor and/or taste characteristics of the CLGT preparation. These results suggest that CLGT prepared by roasting GTL for 60 min at $240^{\circ}C$ does not show any adverse effects on cancer cells and normal cells compared to GTL. They imply that CLGT could be safe for human consumption.
