Using market-selling rice flour, four rice wet noodles were prepared with three hydrocolloids: wheat flour, hydroxypropyl methyl cellulose (HPMC), and potato starch at different levels based on pre-test, and the physical and sensory properties of the noodles were measured and compared. The rice noodle with hydrocolloids showed much higher peak and final viscosity than wheat flour noodle (control). Rice noodle also showed higher hardness, cohesiveness and springiness than control in textural properties, however, the noodle with the highest hydrocolloids (wheat flour 15%, HPMC 12.5%, potato starch 17,5%) showed lowest cohesiveness and springiness values among samples. By sensory evaluation, the rice noodle with 15% wheat flour, 8.5% HPMC, 17.5% potato starch showed the highest scores in appearance, taste, texture and acceptability. HPMC in noodles seemed to influence on the noodle quality than potato starch or wheat flour. For making rice noodle, adequate level of hydrocolloids could improve noodle quality such as viscoelasticity, however, excess addition made the noodle coarse.

The purposes of this study were to identify the actual utilization condition of combi-steam ovens and to evaluate the importance and the satisfaction of dietitians and cooks who used the oven in school foodservice. A survey of 300 schools, 1 dietitian and 1 cook from each school respectively; total 600, was conducted and 202 completed questionnaires were available for the purpose of the statistical evaluation. The main results of this study were summarized as follows: Among the schools, 70.5% set up the oven during 2007~2009, the most commonly used cooking method was 'Baking (87.0%)' and the way of acquiring recipes for the oven was 'from oven manufacturing company (50.0%)'. The advantage of using the oven was 'the convenient use of the oven (63.3%)' and the disadvantage was 'Difficulty of cooking foods evenly (59.8%)'. The degree of importance and satisfaction on twenty six attributes were measured according to type of school, location of school, number of meal service per day, and number of total serving per day. Among quality attributes of importance of the oven utilization, 19/18 characteristics were assessed over 4 point (important) out of 5 scale by dietitians/cooks respectively and in satisfaction 16/18 were over 4 points (satisfied) by dietitians/cooks respectively. When it comes to the most satisfied factor of combi-steam oven, 'Improvement of cooking baked foods' was highest for dietitians (4.60 point) and 'Checking temperature of cooked foods' was for cooks (4.49 point). In overall satisfaction of the oven use, the average score was 4.10 point for dietitians, 3.98 point for cooks out of a 5 point scale. Using the survey results as a base, school foodservices are required to use the combi-steam oven efficiently to serve high quality of meals for students.

The purpose of this study was to examine the level of importance of service quality provided by restaurant when industry meal service recipients used the restaurant. Additionally, the purpose was to compare the level of satisfaction on the respective service qualities of company cafeteria and outside restaurant. The level of relative importance and satisfaction of service quality attributes are comparatively analyzed using the Important-Performance Analysis (IPA) of customers in order to provide basic information on the direction of marketing to efficiently operate company foodservice facilities. Restaurant service qualities were divided into the six factors of hygiene, convenience, food, environment, subsidiary services and food distribution process. The results revealed that the 'environment' of both company cafeteria and outside restaurant was needed to improve as quickly as possible. Additionally, it was found that the level of satisfaction was higher in the 'food' and 'environment' factors when using company cafeteria and outside restaurants, which would become an important attribute for the company foodservice recipients to use outside restaurants than using company cafeteria. Accordingly, it could be said that company cafeteria will need further control of the 'food' and 'environment' factors.

Purpose: Eating behaviors are influenced by food environments, such as availability and/or accessibility of healthy food options. In this study, we examined the relationship between healthy eating-out options and the intention to eat healthily in adults residing in Daqing, China, using an extended theory of planned behavior (TPB). Methods: Data were collected via an online survey conducted from April to May 2021 using a previously validated questionnaire in Daqing. A total number of 308 subjects aged 18-64, either Daqing oilfield workers or their family members were eligible and finally included in the analysis. The relationships among the attributes and the quality of healthy eating-out options, the three major constructs of TPB, and the intentions of healthy eating were examined using multiple linear regression analyses. Results: Subjective norms (p = 0.049) and perceived behavioral control (PBC) (p = 0.000) were significantly related to the healthy eating intention. The quality and attributes of the food served statistically significantly explained the intention to eat healthily. After controlling for age, sex, and body mass index, not the quality but the attributes of food served (p = 0.037), subjective norms (p = 0.016), and PBC (p = 0.000) had a significant relationship with the intention to eat healthily. The model explained 83.7% of the variance. Conclusion: The healthy eating-out choices, along with subjective norms and PBC of TPB, may be a potential determinant of healthy eating intention among Chinese adults living in Daqing, China. Policy implications have highlighted that not only the personal intention to eat healthy foods, but also the available healthy food environment may be important for the choice of healthy options by the population of interest. Therefore, building an environment for healthy eating choices and campaigns aimed at increasing consumer awareness of healthy eating are equally important for a smart eating choice.

Sodium intake has been associated with the health-related quality of life (HRQoL). This study examined the demographic factors related to HRQoL and whether there is an association between sodium intake and HRQoL in adults residing in rural areas. A total of 1,980 adults (aged ≥20 years) were selected from a cross-sectional study conducted between December 2013 and February 2014 in Gyeongju, South Korea. The sodium intake and HRQoL were measured using a validated food frequency questionnaire and the EuroQol Five-Dimension (EQ-5D) (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression), respectively. The education levels (<5 years) were inversely associated with all five dimensions of HRQoL. Men had better EQ-5D scores for each of the five components examined. Adults living with spouses had better scores related to usual activities and anxiety/depression, whereas widowers had decreased scores of mobility and self-care. Unlike older adults aged 70-79 years, adults aged <60 years were more likely to have greater scores related to mobility, usual activities, and pain/discomfort. The income levels were also inversely related to the scores for self-care, usual activities, pain/discomfort, and anxiety/depression. Sodium intake was positively associated with the HRQoL related to self-care, usual activities, and pain/discomfort, but it was negatively associated with anxiety/depression. In conclusion, these findings suggest that the demographic factors and sodium intake were independently associated with HRQoL. The results highlight the need to provide tailored, targeted policies and interventions that consider personal characteristics and dietary intake to improve the overall HRQoL in adults residing in rural areas.

The purpose of this study was to investigate the priority of menu management by importance-performance analysis (IPA) of school foodservice menu attributes. Questionnaires were distributed to 448 school dietitians with an official letter, and a total of 292 responses were used for analysis. From the 21 menu attributes, the factors of 'nutrition', 'educational effect', 'capability consideration', 'ease of quality management', 'efficiency', and 'preference of students' were induced from exploratory factor analysis. The levels of importance (p<0.01) and performance (p<0.05) of the 'nutrition' factor were significantly higher with nutrition teachers than school dietitians, while the importance of the 'preference of students' factor showed significantly higher score with school dietitians (p<0.05). As a result of gap analysis for IPA, only the 'efficiency' factor was located in the area where performance was higher than importance, whereas no menu attribute factors were included in the 'concentrate here' area by the usual IPA. Further analysis showed that there should be more effort to improve the performance of an 'educational effect' factor for a school foodservice menu.
