Kim, Yoo-Kyeong ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 499~502
This study compared the total phenolic contents and antioxidant activities of two seaweed cultivars, Undaria pinnatifida (UP) and Capsosiphon fulvescens (CF), subjected to different drying methods. UP and CF were dried under two different conditions: vacuum drying (VD) at
and hot-air drying (HD) at
. After drying, the total phenolic content, DPPH, and nitrite scavenging activities of the water extracts were determined. Total phenolic contents were 101.94 mg/100 g for UP and 171.35 mg/100 g for CF upon VD-20, and these values were significantly decreased to 67.59 mg/100 g for UP and 141.48 mg/100 g for CF upon HD-60. UP upon VD-20 and HD-60 had 46.17% and 35.20% DPPH radical scavenging activity, whereas CF upon VD-20 and HD-60 scavenged 57.73% and 35.22%, respectively. UP upon VD-20 and HD-60 had 40.36% and 40.01% nitrite scavenging activity at pH 1.2, whereas CF upon VD-20 and HD-60 scavenged 72.35% and 55.24%, respectively. Nitrite scavenging activities of UP and CF were reduced at pH 3.0.

Different amounts of black garlic extract(0, 1, 3, 6, 9 and 12%(W/W)) were added to white pan bread, and the quality characteristics were evaluated. The pH and density of dough was decreased with increasing concentration of black garlic extract. There was no marked difference in the fermentation power of the dough expansion among the samples. The pH of bread decreased, and there were no significant differences in baking loss rate, dough yield or bread specific volume as the concentration of black garlic extract was increased. Regarding crust and crumb color values, lightness gradually diminished with increased amounts of black garlic extract in bread, whereas redness and yellowness increased. For measurement of texture, the highest hardness and gumminess of bread were observed in the 1% added group, and there was no remarkable difference between the 3% added group and control. Sensory evolution was the highest when 6% black garlic extract was added, but there were no significant differences in terms of color or overall acceptability. The results imply that addition of black garlic extract to white pan bread created a healthy and functional bread.

Yoon, Tae-Hwan ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 511~520
The purpose of this article was to study how the 7Ps influence consumers' risk perception of eating at family restaurants in Seoul. In this study, frequency analysis, reliability analysis, factor analysis and path analysis (SEM) of the data were performed. First, reliability analysis confirmed that the 7Ps performance and risk data could be used in this investigation. Path analysis showed that the 7Ps significantly influenced customers' risk perception of eating at restaurants in Seoul. According to the results, product negatively influenced performance risk (p<0.05) and financial risk (p<0.001); price negatively influenced performance risk (p<0.001), financial risk (p<0.001), and time risk (p<0.01); place negatively influenced performance risk (p<0.01) and time risk (p<0.001); promotion negatively influenced financial risk (p<0.05) and time risk (p<0.001); process negatively influenced performance risk (p<0.001) and time risk (p<0.001); physical evidence negatively influenced performance risk (p<0.05) and financial risk (p<0.001); and people negatively influenced performance risk (p<0.05), financial risk (p<0.001), and time risk (p<0.001). As a result, we confirmed that 7Ps were an effective marketing tactic for reducing consumers' risk perception of eating at restaurants. Therefore, family restaurant companies are recommended to administer the 7Ps without additional cost.
Study on Healthy Food Behavior and Recognition of Healthy Asian Food
Min, Kye-Hong ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 521~529
The purpose of this study was to research healthy food behavior and food recognition for each Asian country after subjects had visited Asian restaurants. The subjects of the study were university students from Griffith university and Queensland university, Australia. The survey was conducted from June 1 to 28, 2010. The summary of the analysis is as follows. Firstly, for dietary behavior related to healthy food, 'average' was the most common answer at 41.0% (102 respondents). Regarding the standard of selecting healthy food, 'if it is good for health' was the most common answer, regarding the reasons to like healthy food, 'because it is good for health', was the most common, and for information about healthy food, 'obtain from TV or media' was the most common. Regarding eating healthy food at home or dining out, most respondents answered 'once or twice a week', whereas regarding thinking of eating healthy food while dining out, 'average' was the most common answer. Secondly, the recognition of six Asian cuisines were ranked in the order of Chinese, Japanese, Korean, Thai, Indian, and Vietnamese. Representative well-being food by country, Bibimbap of Korea, Sushi of Japan, Shark's Fin of China, Tom Yum Kung of Thailand, Curry of India and Goi Cuon of Vietnam were selected. Thirdly, regarding recognition of well-being food, disease effect factor, health-oriented factor, nutrition factor and vegetarian diet factor were extracted. We found that disease effect factor and nutrition factor had positive (+) effects on visiting Asian restaurants due to recognition of well-being foods. Therefore, it is expected that more local people will eat at Asian restaurants if the public relations for Asian restaurants emphasizes harmony between well-being food and Asian food.

Kim, Mi-Hyun ; Kim, Mee-Jeong ; Rho, Jeong-Hae ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 530~536
This study was the tenderizing activity of fig and kiwifruit using meat cooking. Furthermore, the effects of various seasonings and flavor spices were investigated. The proteolytic activity of kiwifruit was 36,513 uM/g fruit, whereas that of fig was 24,131 uM/g fruit. The best amount of fruit for meat cooking was 3~5% for kiwifruit and 5% for fig among three different dilutions, 3%, 5% & 10%. The effect of fruit ratio showed that treatment with 'kiwifruit only' produced the best organoleptic results, and there was no significant difference between the kiwifruit and fig ratios, 3:0, 2:1, 1:1. The best marinating time for meat tenderizing by fig and kiwifruit was 6hr at
. The best marinating temperature for meat tenderizing by fig and kiwifruit was
. Fruit sauce containing basic seasonings such as soy sauce, sugar, oligosaccharides, and sesame oil had a pH of 4.64 for fig and 4.23 for kiwifruit. The addition of soy sauce, oligosaccharides, and rice wine decreased the proteolytic activity of the fruits. Fruit sauce containing basic seasonings, garlic, ginger, onion and scallion had a pH of 4.71 for fig and 4.43 for kiwifruit. Finely chopped garlic, finely chopped scallion, and pureed onion, finely chopped ginger, and pear juice, all increased the proteolytic activity of the fruits. There the fruit sauce containing seasonings and flavory spices for meat cooking improved the tenderness and preference in terms of sensory evaluation without undesirable taste or increased fruits.

Lee, Young-Ju ; Ryu, Hong-Soo ; Chun, Soon-Sil ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 537~544
This study was conducted to find an efficient use for mulberry fruit powder (MFP). MFP was added to salad dressing products at concentrations of 0.25, 0.5, 0.75, 1%, and pH, total acidity, viscosity, color, and emulsion stability were measured and sensory evaluation was conducted. There were no significant differences among salad dressing samples regarding pH, total acidity and moisture content. Salad dressing made with 0.5% MFP showed significantly higher viscosity during storage and made the most stable emulsion. For color, the control sample had the highest L and b values, and these values decreased significantly as the amount of MFP in the sample increased. The control salad dressing had the lowest a value of -3.26, and this value increased significantly as the amount of MFP in the sample increased. Sensory evaluation of salad dressing was performed by a trained consumer panel. The flavor intensity increased as the amount of MFP increased in the salad dressing samples. Sweetness was rated significantly higher as the amount of MFP increased in the samples. The control sample had the lowest sourness and off-flavor, but there was no significant difference compared to the samples containing MFP.

Lee, Eun-Suk ; Shim, Jae-Yong ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 545~551
In this study, Sulgidduk samples were prepared with 0%, 3%, 5% and 7% yacon powder. Sulgidduk samples were then examined for quality characteristics such as moisture content, general components, color, texture profile analysis, sensory qualities, and sugar content, in order to determine the optimal ratio of yacon powder in the formulation. Regarding the general components of yacon Sulgidduk, the contents of crude protein and lipid decreased as the ratio of yacon powder increased. The L-value for color decreased, whereas a- and b-values increased. In the texture profile analysis, 7%-added yacon showed significantly lower hardness, whereas 7% yacon powder showed the highest values for cohesiveness, springiness, and chewiness. The contents of sucrose, fructose, and glucose in yacon Sulgidduk were found to be 3%, 5%, and 7% by LC, respectively. Sucrose showed a decreasing trend with increased yacon powder content, but fructose and glucose increased with increased amount of yacon powder. For sensory qualities, taste/flavor, texture, hardness, and overall acceptability were not significantly different among the 0%, 3%, and 5% yacon powder samples.

Lee, Mi-Kyoung ; Choi, Sang-Ho ; Lim, Hong-Sik ; Ahn, Jong-Sung ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 552~558
This study was performed to provide basic data on the use of green laver for jook. To accomplish this, we tested water content, color, brightness, mechanical qualities and sensory qualities in comparison to a control group. Higher concentration of green laver powder decreased water content, lightness, redness, viscosity and pH. Further, higher concentration of green laver resulted in lowered preference regarding appearance. However, better flavor was with the result of a higher amount of green laver. Therefore, green laver seems to have benefits for use in oriental soup. Accordingly, we expect there is potential for use of green laver for jook.

Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 559~566
This study was performed to confirm of characteristics of Sulgidduk containing different amounts of black garlic extract: 0% (T0), 1% (T1), 5% (T5), 10% (T10) or 15% (T15). Samples were analyzed for their physicochemical characteristics and antioxidant activities. According to the results, increasing the level of black garlic extract in the formulation caused the moisture contents of the sample to decrease (38.66~36.79%). Additionally, the L value decreased while the a and b values increased as the contents of black garlic extract in sample increased. Analysis of the texture of Sulgidduk containing different amounts of black garlic extract, found that hardness, gumminess, and adhesiveness decreased, whereas springiness increased; cohesiveness and chewiness did not significantly change. The antioxidant activities of Sulgidduk containing different amounts of black garlic extract were evaluated by measuring 1,1-diphenyl-2-picrylhydrazyl (DPPH) and, 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid (ABTS) radical scavenging activities. In these assays, the Sulgidduk containing different amounts of black garlic extract presented significant radical scavenging activities in a dose-dependent manner.

Cho, Sang-Hoon ; Chung, Chang-Ho ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 567~574
Pork patties were formulated with either steam-dried green tea power or freeze-dried raw tea leaf powder, and the quality characteristics of these products were monitored. Proximate analysis of tea powder contained 17.80~19.85%, 4.70~5.73%, and 5.60~5.77% (as is) crude protein, crude fat, and crude ash, respectively. There were no significance differences in pH among the samples. Chromaticity tended to decrease brightness (
) and redness (
), and there were significant differences in yellowness (
) as the added amount of tea power was increased. For texture, hardness increased as more green tea powder was added. Thiobarbituric acid reactive substances (TBARS) and volatile basic nitrogen (VBN) values increased after storage for 12 days, whereas samples formulated with green tea powder showed lower TBARS and VBN values compared to control groups. Sensory panelists showed preference for samples with green tea powder added compared to the control group.

Kim, Mi-Kyung ; Kim, Weon-Mo ; Lee, Hey-Joeng ; Choi, Eun-Young ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 575~585
This study was performed to determine the optimal composition of a muffin administered dried burdock powder and oligosaccharide. The experiment was designed base on CCD (Central Composite Design), and evaluation was carried out by means of RSM (Response Surface Methodology), which included 10 experimental points with 3 replicates for the two independent variables burdock powder and oligosaccharide. The experimental muffin was made according to a traditional recipe, except that the flour was partially replaced with dried burdock powder (5%, 15%, 25%) and the sugar was partially replaced with oligosaccharide (25%, 50%, 75%). The compositional and functional properties of the prepared products were measured, and these values were applied to the mathematical models. Using the F-test, volume, height, pH, yellowness, chewiness, resilience, springiness, cohesiveness, taste, and overall quality were expressed as a linear model, whereas lightness, redness, adhesiveness, color, flavor, and overall quality were expressed as a quadratic model. The polynomial models developed by RSM for sensory evaluation, color, flavor, texture, taste, and overall quality were highly effective in describing the relationships between the factors (p<0.01). The estimated response surfaces confirmed that the amount of burdock powder had significant effects on color, taste, texture, flavor, and overall quality (p<0.01), whereas and the amount of oligosaccharide had significant effects on color and texture (p<0.01). Increased amount of burdock powder led to reductions of the sensory scores for color, taste, texture, flavor, and overall quality at all oligosaccharide levels. The optimal mixing percentage of burdock powder and oligosaccharide muffin were determined to be 5.00% and 46.25%, respectively.

Park, Bock-Hee ; Koh, Kyeong-Mi ; Jeon, Eun-Raye ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 586~595
This study was conducted to examine the quality characteristics of tofu prepared with Lycii fructus powder(LFP) during storage for 15 days at
. The moisture content, yield rate, tofu whey content and turbidity of soaking solutions of tofu prepared with LFP increased upon the addition of LFP. The pH of tofu prepared with LFP decreased while the acidity increased lightly; however, the acidity of the tofu did not differ significantly according to the level of added LFP. The L value of tofu decreased as the amount of LFP in the formulation increased, whereas the a and b values increased. The color value of tofu prepared with LFP did not depend upon the storage period. The hardness increased significantly with the level of LFP, but it did not differ significantly according to the storage period. The microbial count of tofu prepared with LFP was lower than that of control tofu during the storage period. In terms of overall preference, the preferred tofu contained 1.0% LFP tofu.

Kim, Yoo-Kyeong ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 596~602
The objective of this study was to investigate parents' behavior and attitudes regarding their kids' snacking and dietary life education. A survey was conducted with the parents (N=412) of elementary students from seven provinces, includeing Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Kids' snacks consisted mainly of purchased foods rather than homemade foods. Parents' main concerns regarding kids' snacks were nutrition (44.9%), taste (24.3%), and safety (23.5%). Over 50% of parents checked food labels, especially expiration date (96.4%), food ingredients (49.5%), and food additives (33.5%). The snack items frequently provided to kids were fruits (62.8%), milk (55.5%), bread (47.1%), and snack items (23.3%). Parents responded that the amount of their kids' snacking was adequate (47.8%), small (33.7%), or large (18.2%). The results show that more research is needed regarding the adequacy of kids' snacking, considering that 15.7% and 22.4% of the children ate more and less, respectively, than their daily energy requirement. 76.5% of the parents performed home education regarding their kids' dietary habits, especially on the topics of 'balanced diet' (83.9%), 'healthful food' (53.7%), and 'eating three meals a day' (40.2%). Parents obtained dietary information from TV (65.2%), internet (12.0%), and newspapers (7.0%). From this study, we found that parents perceived their kids' snacking behavior correctly, and considered home-education for their kids' dietary habits positively. However, the information resources were limited, which makes it necessary to develop parents' education programs.
Development of Self-Managed Food Sanitation Check-List and On-Site Monitoring of Food Sanitation Management Practices in Restaurants for Control of Foodborne Illness Risk Factors
Chung, Min-Jae ; Choi, Jung-Hwa ; Ryu, Kyung ; Kwak, Tong-Kyung ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 603~616
Based on recent dramatic increases in foodborne outbreaks in restaurants, self-managed sanitation systems are now recommended to control contributing risk factors. This study aimed to improve sanitation management practices in restaurants and had two objectives. First, we tried to develop a self-managed sanitation check-list, including risk factors contributing to foodborne illness and Korean food hygiene regulation articles. We also tried to evaluate current sanitation management practices in restaurants according to operation and restaurant type. Thirty restaurants were evaluated by on-the-spot inspectors using an auditing tool consisting of four dimensions, seventeen categories, and forty-one items. Total compliance rate categorized by operation type significantly differed between chain restaurants and self-managed restaurants, with values of 85.5% and 51.6%, respectively. Therefore, self-managed restaurants, which showed the lowest compliance rate of below 30.0%, need more strict control to improve current unsanitary management practices, specifically relating to 'sterilization of knives, chopping boards, and wiping cloths', 'sanitation training', 'not allowing access into the kitchen to outsiders', 'handling of food or utensils on shelves at a 15 cm distance away from floor', 'prevention of cross-contamination of cooked foods or vegetables', and 'records of kitchen access or inspection'. Thus, an effective food sanitation system is essential and should be implemented to improve the existing sanitary conditions in restaurants. However, the most important factor to achieving food sanitation management objectives is food handlers' self-motivation.

Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 617~626
The purpose of this study was to determine the optimal mixing conditions of three different amounts of seatangle powder, sugar, and butter in germinated brown rice cookie prepared with seatangle powder. The experiment was designed according to the Central Composite Design of response surface, which showed 16 experimental points including 2 replicates for seatangle powder, sugar and butter. The mechanical and sensory properties of each test were measured, and these values were applied to the mathematical models. A canonical form and perturbation plot showed the influence of each ingredient on the final product mixture. The L value, a value and b value decreased with increasing seatangle powder content and increased with sugar content. The a value and b value increased with increasing butter content, whereas the L value decreased with increasing butter content. Hardness decreased with increasing butter content. The results of sensory evaluation showed very significant values for texture (p<0.001), taste (p<0.01), and overall quality (p<0.05). As a result, the optimum formulation by numerical and graphical methods was calculated to be seatangle powder 4.25 g, sugar 49.86 g, and butter 58.23 g.

Kim, Hyun-Sook ; Shin, Eun-Soo ; Lyu, Eun-Soon ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 627~635
This study was performed to determine the optimal manufacturing conditions of cookies prepared with Hizikia fusiformis. The variables in Hizikia fusiformis cookies production were the amounts of Hizikia fusiformis powder, butter, and sugar. Six sensory characteristics were used for sensory evaluations, including color, appearance, taste, brittleness, hardness, and overall acceptability. The optimal amounts of the three variables were found to be 6.00 g for Hizikia fusiformis powder, 100.00 g for butter, and 70.00 g for sugar against flour powder 200 g, which satisfies a target sensory score (7.0/9.0) according to the response surface method. Cookies with these optimal amounts of Hizikia fusiformis powder, butter, and sugar were tasted by 114 consumers and showed a high acceptability score (7.21). Females preferred the flavor of Hizikia fusiformis significantly more than males did (p<0.05). Older consumers (
years old) scored significantly higher than younger consumers (
years old) in texture (p<0.05). Spread ratio and hardness scores of Hizikia fusiformis cookies were lower than those of control cookies. Color analysis results of Hizikia fusiformis cookies were significantly lower in brightness and redness, and higher in yellowness than control cookies (p<0.01).
Preparation and Characterization of Physicochemical and Sensory Properties of Bread Enriched with Two Types of Wild Grape Extract
Lee, Byung-Yong ; Lee, Malp-Eum ; O, Jin-Hwan ; Kim, Eun-Cho ; Surh, Jeong-Hee ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 636~648
Two types of wild grape extracts(WGE) prepared by different methods were added into butter-top bread at different concentrations(0, 5, 10, 15, 20% of water). Then, the resulting breads were analyzed for their physicochemical and sensory properties in order to identify whether or not the WGE-enriched breads were comparable to control bread in terms of qualities and preferences. Wild grape sugar mixture(WGS), which was prepared by osmotic dehydration of wild grape fruits with the same amounts of sugar, presented significantly lower moisture content and titratable acidity as well as higher pH and sugar content compared to wild grape juice(WGJ), which was produced by boiling the fruits in a vacuum jar and squeezing. The pH of the doughs and breads containing WGE tended to decrease with increasing amounts of WGE, and this phenomenon was more appreciable in those containing WGJ than WGS. This was presumably due to the higher contents of tartaric acid in WGJ. For both types of extracts, hardness, gumminess, and chewiness of the doughs decreased with the addition of WGE, nevertheless, which properties were not remained in the resulting breads. This could be partially attributed to the relatively high degree of baking loss and lower pH of the WGE-enriched breads than those of control bread. Contrary to the mechanical analyses, the sensory properties of the breads were dependent on the WGE type. That is, WGJ-enriched bread showed lower consistency and moistness than control bread, which consequently led to relatively lower overall acceptability. However, WGS addition did not adversely affect the sensory properties of the bread. In particular, addition of 5% WGS somewhat improved the physical and sensory qualities of the bread. Thus, WGE-enriched bread could be produced without loss of bread quality when prepared with 5% WGS.

Chang, Min-Sun ; Kim, Ji-Gang ; Kim, Gun-Hee ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 649~654
This study investigated the recognition of and preference for consumer root vegetables for the improvement of fresh-cut root vegetable quality. The questionnaires consisted of questions on general preference, purchasing locations and quality factors. Answers to 286 questionnaires were analyzed both descriptively and quantitatively using SPSS for Windows (Version 14.0). The principal results were as follows: 37% of the respondents preferred potatoes to other root vegetables; 52% purchased at wholemarket. Most consumers preferred fresh-cut root vegetables; 56% were un-satisfied with fresh-cut vegetables quality as high quality agents. The most considered factor in purchasing fresh-cut root vegetables was shape/appearance.

Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 655~664
This work aimed to investigate the physiochemical properties of commercial sugars (white sugar, dark brown sugar, organic sugar, and muscovado) and sugar beet. Percentages of crude protein, crude fat and crude fiber in sugar beet were 4.06, 6.36 and 0.02%, respectively, and the degrees of sugar of white sugar and sugar beet were
Brix, respectively. L(lightness) value scores of white sugar were higher while the turbidity of sugar beet was higher. White sugar, dark brown sugar, and organic sugar were composed of only sucrose, whereas muscovad and sugar beet were composed of fructose, glucose, and sucrose. The highest organic acid content was observed in sugar beet. The contents of amino acids in sugar beet were in the following order: proline (
/100 g) > aspartic acid (
/100 g) > leucine (
/100 g) > alanine (
/100 g). There were 16 free amino acids in sugar beet. The highest mineral contest was observed in sugar beet in the order of K > Ca > Na > Mg. This result indicates that sugar beet can be prepared by considering the characteristics of natural sugar materials.

Choi, Soo-Keun ; Kim, Dong-Seok ;
Korean journal of food and cookery science , volume 26, issue 5, 2010, Pages 665~675
This study applied high-pressure extraction cooking, which has been proven superior in processibility and stock extraction, for the preparation of stock, which is widely used as a basic material of dishes, and examined the physicochemical and sensory properties of the extracted stock by adding salt. We observed changes in the chromaticity of brown stock according to salt content, and pH decreased with increased the salt content, suggesting that stock was acidified. Regarding the mineral content, Na was the highest, followed by K and P. Regarding total free amino acid content, the content of essential amino acids, enhancing free amino acids, and other amino acids also showed the highest level in S2, which contented 0.3% salt. In the sensory test, saltiness grew stronger with an increase in salt content, and overall palatability was highest in S2. Regarding ranking, preference was highest for S2. Utilize to data that study finding of above is actual in development for mass production of brown stock product licensed cooks' traditional mesh dipper technology quality that make mass production direction that change and normalizes product that can keep excellent taste and improve conservative property develop. Culture formation and our country foodservice industry development that reduce damage of informed people ashes through development of brown stock product that is changed in large quantity, and improve quality of food more positively contributing to reappear diversification of menu, systematization and taste of specialty store as well as can contribute in rationalization of informed people ashes purchase, personnel expense (labor power) curtailment, waste decrease etc. but is developed still more being utilized.
