Objective: To develop healthier comminuted meat products to meet consumer demand, the gel properties, rheological properties, microstructure and water distribution of pork meat batters formulated with various amounts of bamboo shoot dietary fiber (BSDF) were investigated. Methods: Different levels of BSDF (0% to 4%) were added to pork batters, and the pH, color, water-holding capacity, texture and rheological properties of pork batters were determined. Then, pork batters were analyzed for their microstructure and water distribution using scanning electron microscopy (SEM) and low-field nuclear magnetic resonance (LF-NMR). Results: Compared with the control, BSDF addition into meat batters showed a significant reduction in L^*-value and a significant increase in b^*-value (p<0.05). BSDF addition of up to 4% reduced the pH value of pork batters by approximately 0.15 units; however, the cooking loss and expressible water loss decreased significantly (p<0.05) with the increased addition of BSDF. The hardness and gel strength were noticeably enhanced (p<0.05) as the content of BSDF increased. The rheological results showed that BSDF added into pork batters produced higher storage modulus (G') and loss modulus (G") values. The SEM images suggested that the addition of BSDF could promote pork batters to form a more uniform and compact microstructure. The proportion of immobilized water increased significantly (p<0.05), while the population of free water was decreased (p<0.05), indicating that BSDF improved the water-holding capability of pork batters by decreasing the fraction of free water. Conclusion: BSDF could improve the gel properties, rheological properties and water distribution of pork meat batters and decrease the proportion of free water, suggesting that BSDF has great potential as an effective binder in comminuted meat products.

BACKGROUND/OBJECTIVES: With the advances in technologies, self-service kiosks at foodservice operations are becoming a new way of service provision. This study examined the relationships among the menu information quality, nutrition information quality, technology acceptance characteristics, and customer behavioral intention toward the kiosks in fast food restaurants. SUBJECTS/METHODS: A survey with a self-administered method was distributed online and offline. The sample consisted of customers who had used the kiosks at fast food restaurants in the last six months prior to the survey. The study hypotheses were tested by applying structural equation modeling. RESULTS: Structural equation modeling revealed the positive impacts of menu information quality and nutrition information quality, technology acceptance characteristics, and behavioral intention toward kiosks at fast food restaurants. On the other hand, one hypothesis (Hypothesis 4) on the impact of nutrition information quality on the perceived usefulness was rejected. CONCLUSION: The study is the first to investigate nutrition and menu information at foodservice kiosks and relate them to technology acceptance. The study is very timely and adequate in the time of the 4^th industrial revolution. The critical importance of the presentation of nutrition information and menu information at the kiosks at fast food restaurants was verified. The academic and industrial implications of the study findings were discussed.

BACKGROUND/OBJECTIVES: Osteoporosis and osteoporosis-related disease are drawing a lot of attention in Korea as one of the serious health problems. Bone health status may be influenced by the general dietary quality and dietary pattern. SUBJECTS/METHODS: To determine the relationship between dietary quality and intake patterns and bone health status, the %RNI, NAR, DDS, and food group intake patterns were assessed according to their bone health status for 847 postmenopausal women using the 2010 KNHANES data after eliminating those of likely changing their diet under the advice of doctors or those taking estrogen. RESULTS: Bone health became worse as dietary quality deteriorated. All NAR and %RNI values were highly associated with bone health levels and the consumption frequency of Ca sources, DDS and the food group intake patterns also confirmed the findings. CONCLUSIONS: This study confirmed that dietary quality and dietary patterns were important for bone health. Nutritional education on eating foods from the five basic food groups has to be emphasized to prevent osteoporosis among older women.

This study was conducted to identify the relationship among various service quality clues, brand trust, brand distinctiveness and revisit intention focusing on fast-food restaurant consumers. Using online questionnaires tool in South Korea, a total of 450 questionnaires were distributed and 390 participants were used for further statistical analysis through SPSS 21.0 and AMOS 21.0 for Windows. Four service quality factors (menu, interior, exterior, staff) were extracted from twelve questions. According to the result of this study, several service quality factors of fast-food restaurants' have positive effects on brand trust and distinctiveness. Specifically, staff and menu and exterior were significant predictors of brand trust, and staff and menu of fast-food were critical antecedents of brand distinctiveness. In addition, the brand trust has positive influence on brand distinctiveness as well as revisit intention. Although there are many studies which proved the relationships among various selection attributes and other outcome variables such as brand loyalty or image, little research explained the relationships among service quality factors of fast-food restaurants, brand trust, brand distinctiveness, and revisit intention. Therefore, present study will contribute to provide significant results and some practical implications in both the fast-food restaurant industry and academic research.

This study identified the importance and performance perceptions of funeral foodservice service quality toward funeral foodservice employees, chief mourners/the bereaved and funeral visitors. Data were collected using self-administered questionnaires from 102 funeral foodservice employees, 71 chief mourners/the bereaved and 293 funeral visitors. According to the result of the survey, 'hygienic food production process' was recognized as the most important attribute while 'neat appearance of food' had the least performance. By comparing the importance of service quality attributes between three subject groups, it can be identified funeral foodservice employees had the highest recognition while funeral visitors had the lowest (p<0.001). Furthermore, funeral foodservice employees had a significantly high performance level compared to chief mourners/the bereaved in all 19 service quality attributes (p<0.001). The IPA result toward funeral foodservice employees indicated the following attributes that required improvements: 'reasonable menu price' and 'kindness of helpers'. Another IPA result from chief mourners/the bereaved recognized 'reasonable menu price' as a service priority. Overall, implications for funeral foodservice managers regarding service quality improvement are discussed.

This study was conducted to examine the importance and satisfaction of quality attribute, popularization and tourism commercialization of Pohang local food. The purpose of this study was to provide useful information for establishing efficient marketing direction that serves the popularization and the activation of the Pohang local food. On the prospects and improvement of Pohang local foods and its use, 86.1% of subjects stated that the status quo was being maintained or only a portion of the foods was being transmitted. On the dissemination of local foods as world foods, subjects stated 'cooking methods' and 'simplified cooking methods' were required. In the IPA result of Pohang local food quality attributes, it is important to continuously keep 'health', 'nutrition', 'hygiene', 'preference (taste)', 'freshness', and 'credibility toward the ingredients', while 'service' needs to do intensive care and operation. The importance and satisfaction of attributes regarding plans for popularizing local foods and commercializing tourism differed, with importance and satisfaction on average being high, although attributes on plans for popularizing local foods and commercializing tourism was lower than the expectation of customers. Such results mean that residents have high expectations for Pohang local foods, on the other hand, the quality of local foods fails to satisfy the expectations of residents. Therefore, it is important to improve the quality of local foods overall.

Purpose: This study aimed to identify the perception of quality-certified children's preferred foods as well as consumption behaviors of nursery directors and parents. Methods: A total of 243 nursery directors and parents of preschool children were surveyed using questionnaires. Results: Parents' perception scores were lower than directors' scores for many of the questions. Parents showed significantly higher scores for food safety standard questions and nutritional fortifying questions than directors (p<0.001 each). On the other hand, directors showed significantly higher scores for questions about products nutrition and safety (p<0.001, p<0.01). When buying children's favorite food items, food additives and hygiene level of vendors were the most important, in that order. Parents' scores for questions on purchasing behaviors of quality-certified children's preferred foods were significantly higher than those of directors'. Further, respondents with nutritional education experience showed high behavior scores. Conclusion: It can be concluded that promotion of quality-certified children's preferred foods is insufficient. The nutrition education group showed high scores for perception and positive consumption behaviors of quality-certified children's preferred foods. It is important to cooperate with nursery directors and parents of preschoolers to further children's nutritional education.

This study examines the service satisfaction rate on high school students(637) in order to provide the basic data for marketing direction by analyzing the importance and satisfaction rate of the service quality. In IPA for the service quality, as the following properties are high in expectation as well as satisfaction they needed to maintain. They are the taste, scent, saltiness, proper temperature of the food, the quantity main food, nutritional value, the degree of freshness, and the smell of dining room. The following properties need the excessive efforts. They are the number of side dishes, eating place, the shape and material quality of dish, the costume of dining workers. As the following showed low importance degrees as well as satisfaction degrees, they don't need concentrated efforts. They are the harmony of color and shape, the interior design of the dining room, the arrangement of tables and chairs, the atmosphere of dining room, and the effect of nutrition instruction. As the education of nutrition is compulsory among the school group meal, the analysis based on the response of questioned students is supposed to be more careful. The items showing low satisfaction degrees while high importance degrees are considered to make an operational plans for the improvement through a variety of menu, the quality of food, the quantity for side-dishes, health control, the cleanness of dishes, the kindness of cooks, the performance of nutritionists, the charge of school meal, and meal time.

Objective: This study investigated the effect of different acute heat stress (HS) levels on chicken meat quality and ultra-structure. Methods: Chickens were randomly divided into 7 groups to receive different HS treatments: i) $36^{\circ}C$ for 1 h, ii) $36^{\circ}C$ for 2 h, iii) $38^{\circ}C$ for 1 h, iv) $38^{\circ}C$ for 2 h, v) $40^{\circ}C$ for 1 h, vi) $40^{\circ}C$ for 2 h, and vii) un-stressed control group ($25^{\circ}C$). Blood cortisol level, breasts initial temperature, color, pH, water holding capacity (WHC), protein solubility and ultra-structure were analyzed. Results: HS temperatures had significant effects on breast meat temperature, lightness ($L^*$), redness ($a^*$), cooking loss and protein solubility (p<0.05). The HS at $36^{\circ}C$ increased $L^*{_{24h}}$ value (p<0.01) and increased the cooking loss (p<0.05), but decreased $a^*{_{24h}}$ value (p<0.05). However, as the temperature increased to $38^{\circ}C$ and $40^{\circ}C$, all the values of $L^*{_{24h}}$, cooking loss and protein denaturation level decreased, and the differences disappeared compared to control group (p>0.05). Only the ultimate $pH_{24h}$ at $40^{\circ}C$ decreased compared to the control group (p<0.01). The pH in $36^{\circ}C$ group declined greater than other heat-stressed group in the first hour postmortem, which contributed breast muscle protein degeneration combining with high body temperature, and these variations reflected on poor meat quality parameters. The muscle fiber integrity level in group $40^{\circ}C$ was much better than those in $36^{\circ}C$ with the denatured position mainly focused on the interval of muscle fibers which probably contributes WHC and light reflection. Conclusion: HS at higher temperature (above $38^{\circ}C$) before slaughter did not always lead to more pale and lower WHC breast meat. Breast meat quality parameters had a regression trend as HS temperature raised from $36^{\circ}C$. The interval of muscle fibers at 24 h postmortem and greater pH decline rate with high body temperature in early postmortem period could be a reasonable explanation for the variation of meat quality parameters.

Recently the market of the food waste disposer has increased. Therefore, many companies in the development of food garbage disposer has been increasing interest. In this study, we used QFD (Quality Function Development) to find out the quality factors for the development of the food waste disposer reflecting the consumer needs. HOQ (House Of Quality) showing the correlation between consumer characteristic and engineering characteristic was written by investigating the consumer needs based on the consumer complaints and survey. In addition, we generated the CTQ (Critical To Quality) reflecting the weighting of the importance of the parts. As the research result, the important quality factors for the food garbage disposer were the grinding capability, drying, and odor emission features. The crushing motor associated with grinding and dehydration appeared as the most important quality factors among the parts. Second thing was the fan motor associated with odor. The findings will be able to contribute to the development of the food waste disposer reflecting the consumer needs.
