Chae, Kyung-Yeon ; Kwon, Tae-Young ; Hong, Jin-Sook ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 127~133
The aim of this study was to determine the optimum amount of waxy millet flour (WMF) to add to rice flour in the preparation of Sulgidduk (waxy millet rice cakes). According to the results, increasing the level of WMF in the formulation caused the moisture contents of samples to increase (
). The L-value decreased with increasing additions of WMF whereas the b-value increased and the a-value did not differ by the addition of the flour. According to the mechanical evaluation results, hardness increased with increasing amounts of added WMF. Adhesiveness, cohesiveness, gumminess, and brittleness did not differ significantly and springiness was highest at the 30% level of WMF. From the sensory evaluation results, the 30% WMF samples received the highest overall-acceptability scores. In conclusion, according to its sensory and mechanical qualities, the optimal Sulgidduk formulation consisted of 30% WMF added to rice flour.

Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 134~142
This study was conducted to identify the optimal mixing ratios of pomegranate powder or Opuntia humifusa powder for the production of jelly. To establish the amount of pomegranate powder or Opuntia humifusa powder that could be added to jelly, physicochemical sensory characteristics and textural properties were measured. Specifically, jellies were prepared using gelatin that contained a ratio of 0.5, 1, 1.5 and 2%(w/w) pomegranate powder or Opuntia humifusa powder. Sensory evaluation of the sweetness, chewiness, springiness, hardness, transparency and overall acceptability of jelly prepared using 0.5% pomegranate powder resulted in a high score. Similarly, the appearance, sweetness, chewiness, springiness, hardness, transparency and overall acceptability of jelly prepared using 0.5% Opuntia humifusa powder received a high score. Taken together, the results of this study suggest that pomegranate and Opuntia humifusa can be useful in the production of high quality jelly.

Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 143~149
The objective of this study was to evaluate the quality characteristics of lotus root Dasik prepared by different additions of lotus root powder (0%, 20%, 40%, 60%, 80%). As the level of lotus root powder in the formulation increased, the moisture contents of samples increased. Also, the L-, a-, and b-values of samples significantly decreased as the amount of lotus root powder increased. According to the results for mechanical characteristics, hardness, gumminess, springiness, cohesiveness, and chewiness decreased, whereas adhesiveness increased, as the amount of lotus root powder increased. The sensory evaluation results showed that the 40% lotus root sample received the highest preference scores; therefore, the 40% lotus root Dasik prepared with 60 g of flour, 40 g of lotus root powder, and 80 g of honey was chosen as the superior product.

Gwon, So-Young ; Moon, Bo-Kyung ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 150~159
The purpose of this research was to improve the quality of Sulgidduk by additions of green tea or rosemary powder to enhance its functional properties and antimicrobial effects. The green tea or rosemary powders were added to the Sulgidduk at different levels (1 or 3%), and color values, textural characteristics, sensory qualities, pH values, and acetic acid values were evaluated. With higher amounts of green tea or rosemary powder, the L-values of samples decreased and a-and b-values increased. Texture profile analyses indicated that hardness was significantly different among all the samples. The sensory evaluation results showed that the 1% addition of green tea or rosemary powder did not cause significant differences in overall acceptability, flavor, or taste. During storage, pH values decreased in all groups and the control group showed the lowest value. Acetic acid values increased during storage and the control group showed the highest value in the last stage of storage. Finally, the L- and a-values of samples did not change significantly during storage.

Kim, Eun-Mi ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 160~169
This study was performed to examine the quality characteristics of red ginseng wet noodles prepared with additions of carrageenan, xanthan gum, or guar gum. The quality characteristics of the samples were estimated in terms of their general composition, color differences, cooking characteristics, textural attributes, sensory qualities, and microbial growth during storage. The results were as follows. Protein content was significantly decreased in the guar gum added group and ash content was significantly increased in the carrageenan added group (p<0.05). Lipid, water, and Na contents were not significant different among the groups. However, water binding capacity was significantly increased in the group with added xanthan gum. Over 10 weeks of storage, water contents did not differ significantly between the xanthan gum and guar gum added groups. In all the added gum groups, L- and a- values were significantly increased whereas b- values decreased (p<0.05). In texture profile analyses, chewiness, cohesiveness, hardness, and springiness were significantly increased in the carrageenan and xanthan gum added groups (p<0.05). According to sensory evaluations, surface color, red ginseng flavor, red ginseng taste, softness, chewiness, and overall acceptability were considered very good in the xanthan gum and guar gum added groups (p<0.05). Therefore, the red ginseng noodles containing xanthan gum and guar gum were deemed most preferable and presented the safest shelf-life during 10 weeks at -

Kim, Mun-Yong ; Chun, Soon-Sil ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 170~179
This study examined effects on shelf-life extension and prevention of starch retrogradation in rye-wheat mixed bread (RWMB) samples prepared with substitutions of 20, 40, 60, and 80% rye sourdough (RSD) as well as a control made with the addition of naturally fermented raisin extract. These effects were investigated using mold growth, water activity, and textural characteristics during a storage period of 8 days at
. The activities of the rye sourdough were examined in terms of pH, total titratable acidity, general bacteria, lactic acid bacteria, and yeast counts. As the incubation time of the sour dough increased, pH decreased, while total titratable acidity increased. General bacteria, lactic acid bacteria, and yeast counts increased with increasing incubation time. Mold grew on the external surface of the control group after 6 days and on the surface of the RSD bread samples after 8 days, respectively. With regard to water activity, the control group had increasing activity as the storage period increased. In addition, the 20, 40, 60, and 80% RSD samples had increasing water activities until the 4th day however, these strongly decreased by the 6th day. In terms of textural characteristics, as the storage period increased, hardness increased, while springiness, cohesiveness, and resilience decreased. There were no significant differences in gumminess among the samples. The control, 20, 40, and 60% RSD samples had decreases in chewiness with increasing storage time, however, the 40% RSD sample did not differ significantly during the storage period. Finally, water activity was negatively correlated with hardness (p<0.05). In conclusion, the results indicate that substituting rye sourdough in rye-wheat mixed bread has a prolongation effect on shelf-life, but no effect on the prevention of starch retrogradation.

Jung, Bok-Mi ; Park, Soon-Ok ; Shin, Tai-Sun ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 180~188
This study investigated the quality of rice noodles containing different amounts of mesangi (Capsosiphon fulvescens) powder. The noodles were prepared with ratios of 1.9, 3.8, and 5.7% (w/w) of mesangi powder based on the flour weight. The noodles containing mesangi powder had lower moisture contents compared to the control, while amounts of ash were higher than in the control. For the cooking properties of the noodles, weight, volume, and turbidity were significantly higher in the mesangi rice noodles than the control (p<0.0001). The mesangi rice noodles had lower L- and a- values than the control, and these values decreased with increasing amounts of mesangi powder while the b- value increased. Texture profile analysis of the cooked noodles showed significantly higher levels of hardness (p<0.0001) and adhesiveness (p<0.05) in the mesangi rice noodles compared to the control, while cohesiveness (p<0.05), springiness (p<0.05), and gumminess (p<0.0001) values were lower than those of the control. However, the values for hardness, adhesiveness, cohesiveness, and springiness were not significantly different among the mesangi rice noodle groups. The pH of the rice noodles gradually decreased over 8 days of storage time. The 3.8% mesangi rice noodles had lower total and fungus plate counts than the other noodles during 15
24 days of storage. However, the 3.8% masangi noodles showed the highest overall acceptability score(p<0.05).

Lyu, Eun-Soon ; Lee, Hye-Kyong ; Shin, Eun-Soo ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 189~198
This study was conducted to analyse middle school students' perceptions of seafood as well as their eating experiences and favorite cooking methods for seafood. It also examined the frequency and use of seafood on school lunch menus. Questionnaires were distributed to 739 students in 5 middle schools in the Busan area. On a scale of 5.00, the average scores for perceptions toward seafood were as follows: 3.67 for health & nutrition, 3.53 for taste, 2.53 for smell, 2.77 for convenience. The male students had significantly_(p<0.05) higher perception scores for health & nutrition, taste, and smell than the female students. Among 38 types of seafoods, the highest percentages for eating experiences included seaweed_(99.2%), anchovies_(99.1%), fried fish paste_(98.6%), shrimp_(98.4%), crab_(98.2%), squid_(97.9%), sea mustard_(97.8%), mackerel_(97.7%), dried squid_(97.3%), and hair tail_(96.9%). However, the majority of students had eaten a limited amount of seafood. The degree of seafood intake at home was significantly_(p<0.01) higher than at school. The students' favorite cooking methods for seafood were in the order of grilling, stir-frying, steaming, deep-fat frying, and soup. However, the middle school lunch programs primarily served as soup, seasoning, stir-fried, braised, deep-fat fried, and grilled, respectively. The main reasons for leaving seafood on a plate were inconvenience due to the fishbones_(62.7%), tasteless_(45.4%), and disliking the smell_(35.7%). Improvements that students wanted for seafood on school lunch menus included removal of fishbone for convenience_(67.0%), taste_(52.0), and increased variety of seafood types_(38.2%).

Song, Seung-Heon ; Jung, Hyun-Sook ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 199~205
Wet noodles with different percentages of Curcuma Ionga L. powder(CLP) as an additive were generated and their cooking characteristics were evaluated. Wheat flour with 8% CLP had the highest water binding capacity and breakdown, while setback was reversed. Cooked noodle characteristics, weight, volume and tensile strength decreased as CLP content of wheat flour increased, but turbidity of the soup was reversed. L value of wet noodles was higher than cooked noodles, while b value, and texture of wet noodles were lower than cooked noodles. Hunter color value and texture measurements demonstrated decreasing L value, springiness and cohesiveness but increasing b value, hardness, gumminess and chewiness with increasing CLP content. In sensory evaluations, noodles made with 4% CLP were most highly preferred, while noodles made with 2% and 8% CLP were less preferred than CLP-free prepared noodles.

Jeon, Gwee-Yeon ; Ha, Dong-Hyun ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 206~218
The study assessed the relationship between brand evidence (e.g., brand name, price/value for money, servicescape, core service, employee service and self-image congruence) and positive/negative emotion and brand satisfaction, and between positive/negative emotion and brand satisfaction in the family restaurant setting. Also, the relationship of positive/negative emotion and brand satisfaction with customer loyalty were assessed. Customers who used five brands of family restaurant in Daegu and Pusan during October of 2008 were surveyed by questionnaires. Brand evidence was positively related to positive emotion and brand satisfaction, and was negatively related to negative emotion. Positive emotion was positively related to brand satisfaction and negative emotion was negatively related to brand satisfaction. Brand satisfaction was positively relatively to customer loyalty. The results indicate that management of family restaurants should focus on brand evidence as a means of increasing profits and sales volume.

Ku, Su-Kyung ; Choi, Hae-Yeon ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 219~226
Red ginseng extract was added to Yanggaeng to determine a practical use for the herb which has medical usage and functionality. We examined the antioxidant activity and quality characteristics of Yanggaeng prepared with different amounts (as ratios of 1%, 2%, 3% to the total materials) of red ginseng extract, as well as those of commercial red ginseng Yanggaeng. The antioxidant activity of the Yanggaengs samples was estimated by the DPPH free radical scavenging activity,
scavenging activity, and reducing power. The antioxidant activity of the Yanggaeng increased as a result of the addition of the red ginseng extract. Levels of polyphenol compounds and flavonoids increased according to the extract concentration. The quality characteristics of the red ginseng Yanggaeng were estimated in terms of pH, sugar content, viscosity, color, texture profile analysis, and sensory evaluations. With increasing concentrations of the extract, viscosity and sugar content increased, but pH decreased. In terms of the overall palatability, color, taste, flavor, and hardness, the 3% red ginseng Yanggaeng was determined as the best among the tested samples. Also, the 3% red ginseng Yanggaeng had higher scores than the commercial red ginseng Yanggaeng.

Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 227~233
The objective of this study was to evaluate the quality characteristics of Sangwang Mushroom powder at different levels (0 %, 5 %, 10 %, 15 %, 20 %). roximate moisture composition of the powder was 9.22 %. As powder level increased, the moisture content of the Dasik increased the L, a, and b values of the Dasik significantly increased. According to the mechanical evaluation results, hardness and gumminess decreased as the level of Sangwang ushroom powder increased while springness, cohesiveness and chewiness were not significantly different among the groups. In the sensory evaluations, the 10 % Sangwang Mushroom Dasik prepared with 90 g of heat flour, 10 g of Sangwang ushroom powder, and 80 g of honey showed the highest preference scores and was therefore chosen as the optimal product.
Optimization of the Ingredient Mixing Ratio for Preparation of Kiwifruit (Actinidia deliciosa) Jam Prepared with added Barley Sproutling Powder
Jang, Myung-Sook ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 234~242
This study was performed to find the optimum ratio of ingredients for the manufacture of kiwifruit jam. The experiment was designed according to the D-optimal design of RSM (response surface methodology), which included 18 experimental points with 4 replicates for three independent variables (sugar
, kiwifruit paste
). The compositional and functional properties of the prepared products were measured, and these values were applied to mathematical models. A canonical form and trace plot showed the influence of each variable on the quality attributes of the final product mixture. By use of the F-test, viscosity, color values (L, a, b), and sensory characteristics (color) were expressed by a linear model, while the L color value and select sensory characteristics (smell, taste, overall acceptance) were also expressed by a quadratic model. The optimum formulations by the numerical and graphical methods, were similar, and with the numerical method it presented as: sugar, pectin, and barley sproutling powder at 49.7%, 0.5%, and 0.6%, respectively. The above results demonstrate the feasibility of preparing kiwifruit jam added with barley sproutling powder, and therefore, the commercialization of a kiwifruit jam marketed as a functional food is deemed possible.

Choi, Eun-Jung ; Cho, Shin-Ho ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 243~251
Changes in pH and acidity were investigated in kimchi containing different amounts of added onion and/or pear during fermentation at
. As the fermentation period increase, the pH and sugar contents of the onion and/or pear kimchi were higher compared to the control kimchi. However, the acidity of the kimchi containing onion and/or pear was lower than that of the control. To enhance the acceptance of kimchi, the optimal conditions for the addition of onion and pear were evaluated with the central composite design, ANOVA, and response surface methodology. According to variations in the mixing ratio of onion and pear, smell, taste and overall acceptability differed significantly, but the appearance and texture were not different. The optimal levels of onion and pear, predicted on the basis of each corresponding sensory parameters for kimchi, were
for smell, 2.61% and 2.38% for taste and 2.78% and 2.57% for overall acceptability, respectively.

Kim, Mi-Kyeong ; Kim, Jong-Won ; Kim, Mee-Ra ;
Korean journal of food and cookery science , volume 25, issue 2, 2009, Pages 252~259
Ergosterol is the significant component of the cell wall of fungi. Its presence is regarded as evidence of fungi contamination in grain and other foods. Many studies on ergosterol detection have been carried out using chemical methods, but those methods required complicated pre-treatments and long analysis times. In this study, an amperometric biosensor was developed for fast and precise ergosterol detection. The biosensor system used the electron transfer of hydrogen peroxide produced from the reaction of ergosterol with cholesterol oxidase. The biosensor system consisted of a peristaltic pump, a syringe loading sample injector, an enzyme reactor, a fabricated flow-through cell containing a working electrode, a reference electrode and a counter electrode, and a potentiostat/recorder. The working electrode was prepared by coating modified multi-wall carbon nanotube (MWNT) on glassy carbon electrode. The
coated glassy carbon electrode linearly responded to hydrogen peroxide in the range of
M with a detection limit of
M in the basic performance test. The currents produced from the ergosterol biosensor showed the linearity in a range from
