Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 1~8
Extraction conditions were optimized using response surface methodology for preparing high-quality, hot water extracts from cultivated Chrysanthemum indicum L. petals. A fractional factorial design was applied to investigate the effects of added sample ratio (
), extraction temperature (
) and extraction time (
) variables on extract properties, such as, soluble solid contents (
), sugar content (
), ?E (
), turbidity (
), total phenol (
) and DPPH (
). Second-order models were employed to generate a 3-dimensional response surface for dependent variables and their coefficients of determination (
) ranged from 0.8408
0.9914. The range of optimum conditions at
extraction for maximize characteristics of hot water extracts was 2.3

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 9~18
This study was designed to evaluate the effects of hotel brand image on the job preference of students majoring in culinary art through the relationship between hotel brand image and internship satisfaction and internship expectation. The effects were also examined on the personal job preference and job potential as career to the internship. To analyze the proposed hypotheses, a survey questionnaire comprising 61 statements was administered to students majoring in culinary art in colleges located in Seoul and Gyunggi-do. Out of 450 respondents, 420 questionnaires were collected (93.3%) and 411 (91.3%) were analyzed using the statistical package SPSS 12.0. The following results were obtained. First, the regression analysis results for the correlation between hotel brand image and internship confirmed a significant effect of hotel brand image on the satisfaction of internship for students majoring culinary art. Second, according to the correlation results for the internship and job preference, both satisfaction and expectation on internship greatly affected the student's job preference. On the relationship between hotel brand image and internship expectation, the social image of the hotels provided a major contribution to the internship expectation. As well as the internship expectations, the hotel brand image was strongly related with the job preference.

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 25~32
The objective of this study was to investigate the effect of the perceived importance of kitchen equipment and facilities on the hygienic performance of cooks in deluxe hotels. Cooks and chefs at 7 different deluxe hotels participated in this study. Out of 490 questionnaires administered, 456 (93.1%) were completed and 419 (91.9%) were analyzed using a statistical package SPSS 12.0. The results were as follows. First, the correlation between sanitary equipment, including HACCP system, in the hotel kitchens and the hygienic management performance confirmed the significant effect of the sanitary equipment on the performance of the cooks and chefs. Second, the sanitary facilities in the hotel kitchens greatly affected the hygienic management performance. The results also demonstrated that the sanitary equipment provided the same contribution to the performance irrespective of the job level, management type and HACCP practice. However, the sanitary facilities greatly affected the management type expecially the chain hotels. The hygienic management performance did not affect the cooking stage (before-cooking and during-cooking), but affected the after-cooking stage according to the management type and the HACCP practice, but not the job level.

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 33~40
This study investigated the antioxidative and antimicrobial activities of nutmeg (water, ethanol extract and essential oil). The total phenol contents of water, ethanol extract and essential oil were 3.4%, 16.9%, and 3.2%, respectively. Hydrogen donating abilities of water, ethanol extract and essential oil at 1,000 ppm were 4.9%, 41.8% and 6.8%, respectively. The antioxidative activities in linoleic acid substrates were in the order of BHT > ethanol > extract >
-tocopherol > essential oil > water extract. The antioxidative activities in linoleic acid emulsion substrates were in the order of BHT > water extract > essential oil > ethanol extract >
-tocopherol. In antimicrobial activity, ethanol extract showed growth inhibition effect against Micrococcus luteus, Bacillus cereus and Salmonella enteritidis, and the essential oil showed growth inhibition effect against Micrococcus luteus. However, no antimicrobial activity of water extract was observed. The nitrite-scavenging abilities of water, ethanol extract and essential oil at 1,000 ppm were 4.5%, 28.8% and 98.8%, respectively, and the ACE inhibitory activities were 0.2%, 11.0% and 10.0%, respectively.

Ahn, Myung-Soo ; Kim, Chan-Hee ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 41~49
The substitution effects of whey protein isolate(WPI) for egg in the preparation of sponge cake were determined by objective and subjective tests. Milk whey is drained from milk curd as a by-product of cheese manufacture. Whey protein is known as a good nutritional source and a functional material for many processed foods, especially baked goods. WPI contains above 90% whey protein. The specific gravity and viscosity of sponge cakes tend to be affected by WPI substitution. The cooking loss of sponge cakes with WPI substituted for egg(abbreviated as WPI cake) during oven baking was smaller than that made with egg(abbreviated as egg cake) and the specific loaf volume of WPI cake was larger than that of egg cake. The number of pores was highly increased and the size of pores was more uniformly and finely distributed in the cross section of WPI cake than those of egg cake, as observed by scanning electron microscopy(SEM). The hardness, gumminess and chewiness of WPI cake made with 10-20% WPI substitution were the lowest among all the tested cakes, including egg cake, thereby confirming the considerable improvement in their cake qualities. By the results of sensory evaluation, appearance, pore uniformity, softness, chewiness, moistness, flavor, mouth feeling, and overall acceptability of 10-20% WPI substitute cakes were evaluated as being significantly superior to those of all other cakes(p<0.05). These results support the better physicochemical characteristics and sensory evaluations of sponge cake prepared with 10-20% of WPI substitution for egg.

The aim of this study was to determine the optimum amount of astringent persimmon concentrate to add to rice(polished rice, brown rice, and black rice) flour in the preparation of GamJeopyeon (persimmon rice cake). The moisture contents of polished rice, brown rice, and black rice persimmon Jeolpyeon were 50.37
52.44%, and 48.82
51.87%, respectively. With increasing astringent persimmon content, the L value of all of the Jeolpyeon decreased, whereas the values of polished rice and brown rice persimmon Jeolpyeon increased. The b values of polished rice, brown rice, and black rice persimmon Jeolpyeon were the highest at addition levels of 8%, 4%, and 12%, respectively. In the mechanical textural evaluation, the hardness of polished rice and brown rice, persimmon Jeolpyeon decreased with increasing astringent persimmon concentrate content during storage time, and was the highest at the 0% addition level in black rice Jeolpyeon after 2 days storage. In the sensory evaluation, the overall acceptability of polished rice, brown rice, and black rice persimmon Jeolpyeon was higher at 4, 8, 12, and 16% compared to the 0% addition level. According to the above study. Jelopyeon made with the addition of up to 16% astringent persimmon concentrate to polished rice, brown rice, and black rice flour was found to be the best recipe in terms of overall acceptability and textural qualities.

Min, Kye-Hong ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 62~69
Competitions among domestic foodservice businesses get more intense as the presence of new competitors has rapidly increased. For the past decade, our domestic foodservice industry has shown outstanding growth and overcome poor industrial environments. The poor work conditions employees suffer from will cause negative effects on organization values and effectiveness. Although facing severe problems, most of foodservice businesses do not take aggressive counteraction to eliminate these issues. With this in mind, the study has been implemented to empirically investigate the effects of the foodservice business on organization values and organization effectiveness and then to utilize the findings of the study to develop various marketing strategies for the foodservice industry. The findings of the study were as follows: first, with respect to the effects among organization values, job satisfaction, and organization loyalty, the organization value was found to have positive effects both on job satisfaction, and organization loyalty. The findings demonstrated that the levels of job satisfaction and organization loyalty of employees may be increased by promoting organization values, as positive relationships were found between organization values, job satisfaction, and organization loyalty of employees. second, organization values were found to have a positive effect on organization loyalty. Therefore, job satisfaction should be considered as a key factor for achieving overall organizational loyalty of employees in the foodservice industry.

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 70~77
The study was conducted to evaluate the physicochemical and sensory characteristics of sponge cake with different amounts of
-glucan, 2%, 4% and 6%. Addition of
-glucan did not affect the texture property of batter in terms of springiness, cohesiveness, gumminess and hardness. The volume of the sponge cake was significantly decreased in only 6%
-glucan added group, compared to the control. The pH, height, weight and moisture content of the cake were not significantly different between the control and
-glucan added groups. Lightness and yellowness of the cake crust were the highest in the 4%
-glucan group, while redness was decreased with increasing
-glucan content. The color of the cake crumb was not significantly different between the control and
-glucan group, and nor were the texture properties and sensory quality of the sponge cake. These study results show that the addition of
-glucan up to 4% did not affect the quality of sponge cake.

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 78~82
Yulmoo Kimchi becomes sour without carbonated taste when ripened at room temperature after being placed under cold temperature. The carbonated taste of Kimchi is reported to come from the hetero lactic fermentation of Leuconostoc strains. Yulmoo extract was made with methanol and added to four lactic bacteria strains originating from kimchi. The bacteria were also subjected to
for 24 hours as a cold shock treatment. after which Leuconostoc mesenteroide subsp. dextranicum KCCM 40708, Lactobacillus brevis KCTC 3102, Lactobacillus plantarum KCTC 3108, and Leuconostoc lactics KCTC 3528 strains showed a growth inhibition with the addition of Yulmoo extract at the concentration of 250-4,000 ppm. Leuconostoc mesenteroide subsp. dextranicum KCCM 40708, Lactobacillus brevis KCTC 3102, Lactobacillus plantarum KCTC 3108, and Leuconostoc lactics KCTC 3528, a strains appearing at the early stage of Kimchi fermentation, showed a higher growth inhibition following Yulmoo treatment in combination with the cold shock.

Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 83~89
This study was carried out to investigate the quality characteristics of sponge cake with mesangi(Capsosiphon fulvescens) powder added to give a control 0(control), 2, 4, 6 and 8% by weight per wheat flour. The crude protein was 33.37% for mesangi on a dry basis. Batter specific gravity, viscosity and baking loss increased with increasing mesangi powder content, whereas the specific loaf volume tended to decrease. Values of L and B decreased with increasing mesangi powder content while a value was minimized for the 4% mesangi powder. Hardness, cohesiveness, springiness, gumminess, and brittleness of sponge cakes with added mesangi powder content. The sensory tests indicated that aircell uniformity, firmness, sweetness and overall preference were not affected by the addition of 2 and 4% mesangi powder compared to control. Therefore, the addition of 4% mesangi powder to sponge cake was suggested as bing suitable to improve the quality.

Lee, Bong-Shik ; Choi, Mi-Kyung ; Shin, Seo-Young ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 90~98
The purpose of this study was to apply the activity-based costing (ABC) model to restaurant menu costing. The overhead cast of six entr
es in XYZ restaurant was calculated for all levels of activity. When comparing activity-based costing with traditional costing applied to BBQ pork rib and an assorted seafood platter, the total difference of costs between two items was 2,191 won in activity-based costing and 600 won in traditional costing. The average food cast percentage of the six entr
es was 27% using traditional costing, while the average activity-based cost percentage was 40%. Therefore, there was a 13% difference between the actual margin volume and the expected margin volume. The application of activity-based costing to the restaurant industry would be a milestone from a cost point of view as well as from a process point of view. In particular, the limitation that traditional costing only accounts for food costs could be overcome b considering the overhead cost as an important part of the cast structure. Furthermore, activity-based costing would not only help to reduce the costs associated with the process of analyzing the activities but it would also provide more accurate cost information for menu pricing.
Effect of UV-B Irradiation on Vitamin
Contents, Color Value and Flavor Pattern in Pleurotus ostreatus
Lee, Jin-Sil ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 99~106
This study investigated the effect of UV-B irradiation on the quality of Pleurotus ostreatus. The changes of vitamin
contents, color value and flavor pattern in mushrooms were analyzed by high-performance liquid chromatography (HPLC), chromameter and gas chromatography - surface acoustic wave (GC-SAW) electronic nose. By exposure to UV-B irradiation (0 kj/m
, 10 kj/m
, 20 kj/m
content increased from 0 (control) to 48.50 g/g (DM: dry matter, 10 kj/m
) and 61.58 g/g (DM, 20 kj/m
). Although there was no significant difference in L, a, b values among the three groups, flavor changes were detected by GC-SAW electronic nose. The number of peaks increased from 10 in the control group (0 kj/m
), to 14 and 15 for the 10 kj/m
and 20 kj/m
groups, respectively. Nevertheless, the changes of flavor pattern were not detrimental to the mushroom quality. These results suggested that UV-B irradiation is an effective method to increase the vitamin
content without degrading the quality.

There were fifty two kinds of fermented soybean sauce before 17th century thirteen recorded in
, two in
, one in
, nine in
, one in
, six in
, four in
, five in
, two in
, four in
and five in
. These books had thing to know when making fermented soybean sauce like kinds of soybean sauce, how to make it, its ingredients and quantities to be used, how to make fermented soybean sauce in haste, and how to remake wrong made fermented soybean sauce, etc. Before 17th century, fermented soybean malt was divided into two kinds the only soybean malt and the mixed soybean malt that had bean, wheat, wheat flour and wheat bran. The bean only soybean malt was further divided into mashed soybean malt (Beans were steamed and mashed into past.) and unmashed soybean malt (Beans maintained their shape without being mashed.) while mashed soybean malts were made in Winger, in January of February, unmashed and mixed soybean malts were made in Summer, in July. When made fermented soybean sauce, mashed and unmashed soybean malts were used as they were and mixed soybean malt was dried and powdered for use. Fermented soybean sauce before 17th century could be classified by the features of soybean malts being used, Normal fermented soybean sauce was made from bean only soybean malts and other ingredients. Shi(시) was made from unmashed soybean malts, in which beans maintained their shape, and Gowhajang and Jeupjang were made from mixed soybean and wheat bran. Fermented soybean sauce was also made from old fermented soybean sauce, yeast. water leftover after boiling bean leaves, and soybean chaff without soybean malt. There were also side dish type soybean sauce like Kongjaban today and fish and meat sauce made from flesh ingredients. To make fermented soybean sauce in haste, the soybean sauce was heated. Beside there were how to maintain fermented soybean sauce and how to remake wrong made fermented soybean sauce.

Lim, Young-Suk ; Kim, Haeng-Ran ; Han, Gwi-Jung ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 124~139
This study was conducted to evaluate the degree of value assigned to traditional Korean foods by residents from the Kyunggi(n=582) and Kangwon(n=189) areas of Korea. We determined the degree of value for 13 items classified as traditional Korean foods by asking subjects to score the items based on a 5 point Likert scale. Based on the total scores, resident in Kyunggi assigned Kimchi the high degree of value. Next was Tteok, then Eum-cheong, Jang, Hankwa, Muk, Bap, Jeon, Namul, and Guk, respectively. In the Kangwon area, the total scores showed that Kimchi also had the highest degree of value, followed by Tteok, Jang, Hankwa, Eum-Cheong, Muk, Bap, Namul, Jeon and Myeon, respectively. The female residents in Kyunggi gave Kimchi a higher degree of value than the male residents'. Also, subjects with overall higher positive perception of traditional foods had a higher degree of value for Kimchi. Relative to age, ther was a trend showing older subjects had a higher degree of value for Kimchi than Younger subjects. In the case of the head of the family, residents of the Kangwon area showed a trend toward a high degree of value for Kimchi. The residents in Kyunggi, compared to the residents in Kangwon, evaluated the Jang food group as inexpensive foods(p<0.05). However, there was no significant difference between the residence areas for the total score of the items. Overall, the resident's evaluation of the degree of value traditional Korean foods increased with increasing age.
Recognition of the university students in Seoul of the passage rites and foods-one hundredth birthday and the first birthday rites and wedding ceremony
Yun, Hye-Hyun ; Kim, Mee-Jeong ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 140~149
This study investigated the thoughts of undergraduate students in Seoul about the birth rites and wedding ceremony and their foods. Among 524 students who were surveyed, 299 students answered that the meaning of the first birthday rites was for special memory, followed by the child's future and family's harmonies. 248 desired birth rites to remain unchanged and 150 desired extravagance and waste to be reduced. Regarding wedding ceremony, 328 answered that changes are necessary in wedding ceremony gifts. Next, process in wedding ceremony and bridegroom's gift box should be changed, Most of the students didn't know clearly the foods of the one hundredth birthday and the first birthday; nevertheless they considered the birth rites to be necessary. Regarding wedding ceremony, half of the students knew the process and half didn't. Two hundred students answered they knew ordinarily about the foods of wedding ceremony. There were no significant differences in hometown about foods of wedding ceremony. In parent's religions, there were no differences about gifts & foods offered by the bride. The Buddhist students knew well about the birth rites' foods and considered birth rites to be necessary. The correlation of parents' work and student's major and passage rites showed that professional parents knew well about birth rites' foods but religious believers didn't know well. Students majoring in natural science were not concerned with birth rites and thought that they were unnecessary and they didn't know about wedding ceremony process and foods. Knowledge about birth rites increased with increasing number of siblings. Large families were interested in birth rites and knew well about the wedding process, wedding ceremony foods and gift & foods offered by the bride.

Kang, Ok-Ju ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 150~155
This work was conducted to obtain a rapid, accurate, and precise procedure for free amino acids analysis in Doenjang with HPLC-OPA (high performance liquid chromatography using-phthalaldehyde) and AAA (automatic amino acid analyzer) methods. Different sample extraction procedures among water, 0.1 M perchloric acid, and 0.1% meta-phosphoric acid were also compared. The optimal extraction solvent was 0.1% meta-phosphoric acid for both the HPLC-OPA and AAA methods. Good recoveries for glycine and methionine were observed using the 0.1% meta-phosphoric acid extraction with HPLC-OPA method. Method precisions (% relative standard deviation) for the free amino acids ranged for 1.62% to 8.27%, in which the HPLC-OPA method with water extraction showed the lowest value at 1.62%. Inhibition rates of the free amino acids in Doenjang were greatest with an addition of NaCI at a 1% concentration.

Lee, Yeon-Jung ;
Korean journal of food and cookery science , volume 23, issue 1, 2007, Pages 156~164
This study investigated the impacts from the recognition and satisfaction of Korean foods on the revisit intentions of japanese tourists to Korea. The subjects of this study consisted of 365 Japanese tourists visiting Korea. The findings are summarized as follows: (1) the recognition of Korean food included 'the quality of food material is fresh and good'(3.99 pints), 'Korean food is nutritious and healthful food'(3.89 points), and 'Koran food consisted of grains and vegetables, and the cooking methods were developed specially'(3.88 points) in the order. (2) They were highly satisfied with the 'nutrition of the food,' 'taste of the food,' and 'quantity of the food,' in terms of the Korean food quality however, they were not satisfied with 'Japanese marks on ingredients,' 'sanitary,' 'smell,' and 'freshness.' (3) The most influential recognition variables to affect revisit intentions to Korea was 'health knowledge' followed by 'unique,' 'preference,' 'experience,' and 'interest.' (4) The most influential satisfaction variable to affect revisit intentions to Korea was 'food and menu' followed by 'translation and understanding,' and 'flavor and appearance.'
