Korean journal of food and cookery science , volume 25, issue 5, 2009, Pages 521~530
Perilla leaves powder was added to cookies to determine a practical use for the herb, which has been shown to have medical benefits and functionality. We examined the antioxidant activity and quality characteristics of cookies prepared with different amounts (as ratios of 0.5%, 1%, 3%, 5% to the total materials) of perilla leaves powder. The antioxidant activity was estimated by DPPH free radical scavenging activity and the total phenolic compound content in perilla leaves powder and cookies. The quality characteristics of the perilla leaves cookie were estimated in terms of the bulk density, pH of the dough, spread factor, loss rate, leavening rate, color, texture profile analysis, and sensory evaluations. While the bulk density and pH of the dough as well as total polyphenol contents and DPPH free radical scavenging activity of cookies significantly increased, the spread factor, loss rate, leavening rate and L value of the cookies decreased with increasing perilla leaves powder content(p<.05). The consumer acceptability scores for the
perilla leaves cookie groups ranked significantly(p<.05) higher than those of the other groups in appearance, taste, flavor, texture, and overall preference. This study suggests that perilla leaves powder is a good ingredient to increase the consumer acceptability and the functionality of cookies.

Strategic alliance is increasingly becoming a popular strategy in the family restaurant industry. In general, strategic alliance can be defined as several brands collaborating in technology development, marketing, or production while keeping their independence as separate business entities. This study identified segments on the basis of sales promotion resulting from strategic alliances between family restaurants and card companies. This study further investigated how brand image, brand value, price fairness, customer loyalty and demographics are different among the segments. From the statistical analysis, three segments were found; 'short-period benefits oriented' segment, 'intangible and discount benefits oriented' segment and 'free benefits oriented' segment. Among the three segments, the 'free benefits oriented' and 'intangible and discount benefits oriented' segments had greater perceived brand image, brand value and customer loyalty than the 'short-period benefits oriented' segment.

The purposes of this study were to understand the influence of perceived service quality in Korean food restaurants on customer satisfaction and behavioral intention and to empirically analyze whether trust plays a mediating role between both the relations of the perceived service quality and customer satisfaction and the perceived service quality and behavioral intention. Based on total 303 samples obtained from empirical research, this study reviewed the reliability and fitness of the research model and verified a total of 5 hypotheses using the Amos program. The hypothesized relationships in the model were tested simultaneously by using a structural equation model(SEM). The proposed model provided an adequate fit to the data,
= 536.566, p<.01, RMR .126, GFI .841, NFI .896, CFI .919, RMSEA .101. The SEM results showed that the perceived service quality(
= .823, t = 9.392, p<.001) had a significant positive effect on trust had a significant positive effect on trust, and trust had a significant positive effect on customer satisfaction(
= .730, t = 14.202, p<.001) and behavioral intention(
= .239, t = 3.362, p<.001). Also, customer satisfaction had a significant positive effect on behavioral intention(
= .509, t = 6.978, p<.001). In addition, the effect of the perceived service quality in Korean food restaurants upon behavioral intention was found to be partially mediated by the trust.

Yong, Eun-Zu ; Lee, Keun-Taik ;
Korean journal of food and cookery science , volume 25, issue 5, 2009, Pages 557~563
In this study the perception and consumption of processed meat products by students in food service schools was investigated. The total number of subjects in Seoul and Gangwon province used for this survey was 569. The most preferred processed meat product for students was the fried pork cutlet(17.7%), followed by bacon(11.4%), ham(7.9%) and sausage(7.6%). The main reasons for the consumption of these processed meat products were 'good taste'(52.5%), 'convenience in eating'(18.8%) and 'as the parent buy'(18.8%). The preference for the processed meat products had a relatively high perception value(4.0). However, the effect of consuming processed meat products on nutrition and health had a relatively low perception value(2.9). Reasons for distrusting the processed meat products were attributed to 'bad influence by media'(25.9%) and the 'unsanitary manufacture'(23.6%). In regards to the question about sodium nitrite, most of the students(56.2%) replied that they had 'never heard of it' or 'didn't know it well'. In conclusion, an improvement in public information would be a prerequisite for expanding wholesome use of processed meat products.
Evaluation of the Effects on Food Service Quality and Food Purchasing Attitudes According to the LOHAS level of School Foodservice Employees
Lee, Yeon-Jung ;
Korean journal of food and cookery science , volume 25, issue 5, 2009, Pages 564~574
This study was conducted to evaluate the effects of the LOHAS index value of school food service employees on the purchase of food materials and foodservice quality. The subjects consisted of 566 foodservice employees. The findings were as follows. (1) The foodservice employee's LOHAS index fell within that of a NOMADICS group with an average of 72.18 points out of 100 points. (2) When the age, working experience and LOHAS index of the foodservice employees was high, the necessity, view, interest and recognition of LOHAS introduction for the improvement of the foodservice environment was high. (3) The amount of environmentally-friendly food materials purchased by foodservice employees was high, when they had a high LOHAS index. (4) High foodservice quality management items of foodservice employees were 'sanitation management' (3.87 points) and 'human resource management' (3.84 points), whereas 'menu management' (3.57 points) and 'food material and inspection management' (3.61 points) scored low. (5) The LOHAS index of foodservice employees has a significant impact on the purchase intention of environmentally-friendly food materials in LOHAS and NOMADICS groups. (6) This study confirmed that a higher LOHAS index of foodservice employees was associated with higher foodservice quality management behavior, which leads to an improved quality of foodservice.

Korean journal of food and cookery science , volume 25, issue 5, 2009, Pages 575~585
This study was conducted to identify the job stress factors of school foodservice employees and to examine the relationship between job stress and turnover intention through path analysis. Data was collected using a survey of 432 school foodservice employees in elementary and secondary schools in Masan, Kyungsangnam-do. All of the participants were female, and 165(52.9%) were over the age of 45' Additionally, 310(99.4%) of the respondents were married, while 287(92.0%) had less than a high school level of education. Furthermore, 271(86.9%) of the respondents were cooks. Overall, 107(34.3%) of the respondents had worked in the food industry for less than
years. In addition, 208 (66.7%) respondents answered that they had 'never' changed jobs. Among job characteristics that causes job stress, job posture was the primary stress factor, followed by heavy work load and job condition. Job stress was found to be significantly correlated with turnover intention. Additionally, job position was the only moderating variable that was found to be correlated with job characteristics and job stress. Finally, the moderating variables influencing the effects of job stress on turnover intention were identified as performance confidence, job career, and job position. The results of this study will be useful for future studies conducted to evaluate the development of job environments and performance to minimize turnover and job inefficiency as a result of job stress.

Sulgidduk samples containing 2, 4, and 8% red ginseng powder and a control[ED highlight - consider specifying what the control was, if 0%, then change to Sulgidduk samples containing 0(control), 2, 4 and 8%] were examined for moisture content, color, gelatinization properties, textural characteristics, and sensory qualities to determine the optimal ratio of red ginseng powder in the formulation. The moisture contents among the samples did not differ significantly. Specifically, they ranged from 39.64 to 40.69%, and increased as the red ginseng powder content increased. Additionally, the lightness decreased and the yellowness and redness increased as the red ginseng powder content increased. Evaluation of the gelatinization properties revealed that the, peak viscosity(P), hold viscosity(H), final viscosity(F), setback, and time to peak viscosity decreased with increasing red ginseng powder content, but the breakdown and temperature to peak viscosity did not differ significantly among samples[ED highlight - please ensure my changes are correct]. The hardness and adhesiveness decreased with increasing red ginseng powder content, as did the cohesiveness, gumminess, and chewiness; however, the springiness did not differ significantly among samples. Sulgidduk containing 4% red ginseng received the highest scores for flavor, taste, texture and overallquality. Based on the above results of the sensory and texture analyses, Sulgidduk containing 4% red ginseng had the highest quality[ED highlight - please ensure my changes are correct].

Kim, Heh-Young ; Lee, Yun-Hee ;
Korean journal of food and cookery science , volume 25, issue 5, 2009, Pages 632~642
In this study the microbiological quality of vegetables was evaluated in relation to the sanitization methods used and vegetable types which consisted of raw food ingredients used in foodservice operations. We analyzed the microbial quantities on lettuce and spinach, which were used as leaf vegetables and cucumber and tomato, which were used as fruit vegetables according to various disinfection methods using different chlorine concentration(50 ppm, 100 ppm, 200 ppm) and exposure time(5 min, 10 min) over 5 days. When the effects of the disinfection methods on microbial qualities and sensory evaluation were analyzed, the following results were obtained. First, in the leaf vegetables, disinfection with a chlorine concentration of 200 ppm for a 5 minutes exposure time was needed to control microbial growth. Second, fruit vegetables sterilized with tap water had reduced microbial qualities after an extended amount of time relative to chlorine disinfection, that is, disinfection with a chlorine concentration of 50 ppm for 5 minutes exposure time was desirable.
