This study was performed to investigate the quality characteristics of noodles made from four different potato varieties: Atlantic, Go-un, Sae-bong, Jin-sun, and wheat flour. Quality characteristics of five noodles were analyzed by general components analysis, cooking quality (rate of water absorption, cooking loss, and volume increase), and mechanical textural properties. Some variations existed in wheat- or potato-based noodles for the general components analysis, but no clear trend was observed. Higher values in the rates of water absorption, cooking loss, and volume increase were observed for the wheat flour noodle, while some variations were observed for potato noodles depending on the variety. The wheat flour noodles exhibited higher values of textural characteristics obtained from the texture profile analysis, except for adhesiveness. Higher gluten contents as well as lower ash contents in the wheat flour noodles compared to the potato noodles are thought to be the two key factors contributing to this finding.

The objective of this study was to examine the relationship between instrumental tenderness parameters and histochemical characteristics in the porcine longissimus dorsi muscle, and to investigate a comparison between tenderness parameters such as the Warner-Bratzler shear-force (WBS) and texture profile analysis (TPA). A negative relationship between WBS and fiber area was observed. However, there was no significant relationship between hardness and muscle fiber area. The percentage of fiber type IIb exhibited a positive correlation with hardness. There was a negative relationship between the type IIa composition percentage and hardness. This study showed that some muscle fiber characteristics were related to WBS and TPA parameters, especially hardness.

The objective of the current study was to compare the execution of hygiene and safety management according to the characteristics of children's food service stations, with the ultimate objective of providing sanitary and safe food service to children. To this end, the study conducted surveys of 73 public and private pre-schools with fewer than 100 children in district A from July 30 to October 31 2015. The differences were evaluated by t-test and analysis of variance. The confidence and validity of the results were analyzed by six food ingredient and facilities management questions, three personal hygiene and facilities management questions, four environmental management questions, and five storage and treatment management questions; for a total of 18 questions. The cumulative distribution of the four factors was 61.569%, and the Cronbach's alpha was 0.821, which indicated that the results were reliable. The results revealed that public pre-schools (a) and home-based pre-schools (b) had different levels of food ingredient and facility management, but no differences in the number of cooks, number of children served, type of food distribution, and the existence of mass food service facilities. The results of the study may be used to develop hygiene and safety management manual and educational contents to promote the health of the children served.

In this study, we investigated the quality characteristics of noodles supplemented with lyophilized leg-meat powder from the red snow crab, Chionoecetes japonicus (CP). The noodles were prepared by adding 0, 2, 4, 6, 8, 10% of CP on a wheat-flour basis. The ash, crude protein and crude lipid contents of noodles increased with increasing CP content. The cooked weight, volume and water absorption values of noodles decreased, whereas the turbidity increased, with increasing CP content. The L values of the noodles decreased with increasing CP content, whereas the a and b color values increased. The hardness, gumminess and chewiness values increased with increasing CP content increased, while springiness and cohesiveness showed no significant differences among the groups. In the sensory evaluation, cooked noodles with 4-6% CP had greater overall acceptability than the noodles with other CP levels.

The need to further improve food quality and reduce food waste leads to increased attention for the development of Food Supply Chain Management (FSCM) which considers intrinsic characteristics of food supply chains besides traditional supply chain management (SCM) objectives such as cost and responsiveness. Growing consciousness of society towards sustainable development brings additional objectives to the food supply chains and the fast evolution of sustainable development results in the development of a new fast-growing concept: Sustainable Food Supply Chain Management (SFSCM). In response to these developments, researchers have developed various decision support tools that can be used for handling progressively increasing complexity along the alteration process from SCM to FSCM and now to SFSCM. This study reviewed literature on sustainable food logistics management to identify logistical key issues and relevant challenges. The evaluation of the reviewed papers shows that towards obtaining sustainability together with considering intrinsic characteristics of food supply chains, there is a gap between the needs of the practice and the current available method.

The effects of sea tangle, sea mustard, hijiki, and glasswort were investigated based on the proximate composition, salinity, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics of reduced-salt (NaCl) meat batter and frankfurters. The moisture content, salinity, lightness of the meat batter and frankfurter, hardness, gumminess, and chewiness of the reduced-salt frankfurters with sea weeds were lower than the control without seaweed (p<0.05). The protein content, springiness, and cohesiveness of the reduced-salt frankfurters were not significantly different among the treatments (p>0.05). The moisture content, salinity, cooking loss, lightness, redness, hardness, gumminess, and chewiness of treatments with sea tangle and with sea mustard were lower than the control (p<0.05). Among the sensory traits, color was highest in the control (p<0.05). The flavor was also highest in the control. The treatments with sea tangle and with sea mustard samples had high tenderness, juiciness, and overall acceptability scores similar to the control (p<0.05). The results of this study show that the combination of low-salt and seaweed in the formulation successfully improved reduced-salt frankfurters, improving sensory characteristics to levels similar to the regular salt control (1.5%).

Objectives: The purpose of this study was to examine the food allergy-related knowledge, awareness, and performance of dietitians at children's hospitals, depending on whether or not they have a clinical dietitian certificate. Methods: A questionnaire survey was administered to 41 dieticians at children's hospitals registered as a part of the Korean Hospital Association. The survey consisted of questionnaires examining general characteristics, nutritional counseling-related characteristics, and food allergy-related characteristics (food allergy-related knowledge, awareness, and performance). We examined differences according to the status of clinical dietitian certification. Results: The proportion of subjects who were holders of clinical dietitian certificates was 48.8%. There were differences between holders of clinical dietitian certificates and non-holders as follows. Regarding nutritional awareness and performance, 'needs to provide nutrition counseling in children's hospitals', 'providing nutrition counseling services in working hospitals', and 'whether there is a nutrition counseling room' scored higher among holders of clinical dietitian certificates than non-holders. Holders of clinical dietitian certificates showed higher scores for knowledge of food allergy symptoms and food allergy management than non-holders. For food allergy awareness and performance, 'self-assessment of food allergy knowledge understanding level', 'awareness of open oral food challenge (OFC)', 'recognition of the need for education and counseling on food allergy for patients / guardians', and 'food allergy related educational experience' scored higher among holders of clinical dietitians certificates than in non-holders. Conclusions: Children's hospital dietitians with a clinical dietitian certificate showed high knowledge, awareness, and performance related to food allergies. It is thus necessary to employ a clinical dietitian for food allergy management in children's hospitals. In addition, training and conservative education are necessary for the management of food allergies for children's hospital dietitians.

The object of this study was to employ effective marketing methods using SNS by determining how food-related SNS usage characteristics have influence on dine-out motivation and restaurant satisfaction and how this affects people's quality of lie. Survey respondents were men and women who have had used some kinds of food-related SNS. The survey included general characteristics of respondents, food-related SNS usage characteristics, dine-out motivation, restaurant satisfaction, and food-related quality of life. Food-related SNS usage characteristics were divided into convenience, effective time-spending, and informative; Dine-out motivation was sorted into entertainment motivation and social motivation by factor analysis. Analysis of the connections between the variables by AMOS showed that among food-related SNS usage characteristics, convenience did not have a significant influence on either entertainment or social motivation. Informative had a positive effect on entertainment motivation (p<0.05), but not on social motivation. On the other hand, effective time-spending through food-related SNS had an impact on both entertainment (p<0.001) and social (p<0.05) motivation. Moreover, the effect of dine-out motivation on restaurant satisfaction showed that entertainment motivation (p<0.05) and social motivation (p<0.01) both have significant influences on restaurant satisfaction. Also, restaurant satisfaction turned out to affect quality of life (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; (p<0.05). As a result of this study, the usage of food-related SNS did not directly influence customers' restaurant satisfaction and quality of life; however, it had an impact on dine-out motivation and gain pleasure of dining out and help improve the quality of life in the long run; thus, it is believed that marketing strategies thorough SNS by restaurant industry are required.

In this study, we sought to investigate the various characteristics of Salmonella spp. isolated from raw chicken meats available in Korean markets. The data collected, such as food source of isolation, sampling information, serotype, virulence, and genetic profile including sequence type, were registered in the database for further comparative analysis of the strains isolated from the traceback investigation samples. To characterize serotype, virulence and gene sequences, we examined 113 domestically distributed chicken meat samples for contamination with Salmonella spp. Phylogenetic analysis was conducted on 24 strains (21.2%) of Salmonella isolated from 113 commercially available chicken meats and by-products, using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Serotyping of the isolated Salmonella spp. revealed S. Enteritidis in 11 strains (45.8%), S. Virchow in 6 strains (25%), S. Montevideo in 2 strains (8.3%), S. Bsilla in 2 strains (8.3%), S. Bareilly in 1 strain (4.2%), S. Dessau in 1 strain (4.2%), and S. Albany in 1 strain (4.2%). The genetic correlation indicated that 24 isolated strains were classified into 18 clusters with a genetic similarity of 64.4-100% between them. Eleven isolated S. Enteritidis strains were classified into 9 genotypes with a sequence identity of 74.4%, whereas the most distantly related S. Virchow was divided into five genotypes with 85.9% identity. Here, the MLST analysis indicated that the major Sequence Type (ST) of the Salmonella spp. isolated from domestic chicken sold in Chungcheong Province belongs to the ST 11 and 16, which differs from the genotype of Salmonella isolated from imported chicken. The differential sequence characteristics can be a genetic marker for identifying causative bacteria for epidemiological investigations of food poisoning.
