Fermentation temperature (10 and $20^{\circ}C$) and salt concentration (10, 20, and 30%) on volatile basic nitrogen (VBN), histamine, amino nitrogen, total viable cell counts, coliform bacteria and Escherichia coli counts as the quality index in salted shrimp were investigated during fermentation. Results show that the effect of salt concentration on changes in quality index was not high compared with fermentation temperature (10 and $20^{\circ}C$) in salted shrimp treated with 10% and 20% salt concentration. However, effect of salt concentration and fermentation temperature on the quality index was not significant with 30% salt concentration. And all most whole changes of quality index were rapidly increased or decreased for 30 days of fermentation.

The classification and evaluation of cooking that is being published on the internet are presented without scientific criteria based on individual subjective factors. In this paper, we objectified the degree of cooking difficulty based on the information entropy. And we measured the similarity by calculating the common entropy between recipes and constructed a social network based on the recipe similarity. As a result of measuring the cooking difficulty, 'Dongtae Haemul-jjim' (Korean) and 'Vegetarian Lasagna' (Italy) are the most difficult recipes and 'Gochu-jang' (Korean) and 'Tofu steak' (Italy) are the easiest recipes. Through the recipe network, the similarity between Korean and Asian cooking is higher than Western cuisine. We showed a similar recipe to a particular cooking, the group of similar recipes, and reasonable schedule when preparing the menu from the viewpoint of ease of cooking.

China has not thousands years history and culture but more than 50 times huge territory compare to Korea. Moreover, China is a multiracial country which has 56 minority races including Han race. Today's food culture of China has been established based on historic, regional, and racial features. China is located adjacent to Korea and historically has had close relationship with Korea. Moreover, China and Korea have had interaction in politic, economic, and cultural respects. In this aspect, the food culture of China has had great influence to the food culture of Korea. Therefore, this study purposed to understand the food culture of China more deeply which has been passed over, through researching food culture based on Chinese foods in five thousands historic stream. As the result of researching Chinese food by times in terms of food culture, which has been well known by only cuisine, the food culture of China had been changed by rise and fall of several dynasties. In addition, food styles had divided the south and north by inflowing western food materials and deep relation to Buddhism, Confucianism, Taoism, and the principles of yin-yang.

In this study, a survey was conducted among university students (119 men and 134 women) in Chungbuk province using questionnaires to investigate the variables and eating patterns related to the use of food delivery apps. A survey was conducted from March 22, 2019 to April 3, 2019. Of the total respondents, 77.2% reported that they had ordered food at least once using food delivery apps on smartphones. Further, 63.3% of the total subjects had ordered food delivery through smartphone apps once or twice a month, and the most preferred cuisine for food delivery was fast food, followed by Bunsik (Korean street food/snack), western food, and Chinese food. The average satisfaction scorefor food delivery apps was 3.8 points, and the satisfaction score was the highest with the convenient ordering process (4.0), followed by good taste (3.9) and good portion (3.8). The subjects who used smartphone food delivery apps three times or more a month showed a significantly higher frequency of instant food intake (p=0.0132), dining out (p=0.0282), and late-night eating (p=0.0047) than the subjects who ordered food using delivery apps less than three times a month. In conclusion, these study results may be applied as baseline data for dietary education among university students.

We investigated methods for extracting histidine-containing low-molecular-weight (LMW) peptides such as anserine, carnosine and histidine from the edible meat of tuna byproducts. Extracts were treated by several methods including heat treatment ($80^{\circ}C$, 10 min), DOWEX ion exchange (IEC), ultrafiltration (UF), and carboxymethyl (CM)-cellulose column chromatography (IEC+CMC); then the levels of protein, total iron, histidine, carnosine, and anserine were measured. Extracts treated with IEC+CMC using CM-cellulose were analyzed for total iron, protein, histidine, and anserine content, which were $6.27{\pm}0.26mg/mL$, $5.20{\pm}0.21{\mu}g/mL$, 0.80 mg/mL, 0.208 mg/mL, and 4.40 mg/mL, respectively, in yellowfin tuna; and $9.05{\pm}0.82mg/mL$, $4.06{\pm}0.20{\mu}g/mL$, 1.62 mg/mL, 0.012 mg/mL, and 7.28 mg/mL in bigeye tuna. By comparison in IEC-UF treated extracts, protein, total iron, and histidine content decreased by 43%, 73%, and 27% in yellowfin and 0.4%, 54%, and 23% in bigeye tuna, wheres carnosine and anserine content increased by 22% and 17%, respectively. Freeze-dried (FD) extracts exhibited similar trends as non-dried extracts, i.e., dipeptide content increased with purification steps, whereas pro-oxidant (total iron and protein) content decreased. IEC+CMC treated FD extracts had the highest anserine, content, and the greatest reductuion in pro-oxidants.

This study was conducted to investigate changes in the quality of Gochujang following the addition of sea tangle Saccharina japonica powder fermented by lactic acid bacteria (FSP). Gochujang was prepared with or without FSP and fermented at $16^{\circ}C$ for 24 weeks, as detailed in a previous study. No significant physicochemical changes in moisture, crude protein content, pH, salinity and amino nitrogen content were observed among the varieties of Gochujangs evaluated (Commercial Gochujang, Gallic-Gochujang and FSP-Gochujang). In addition, we detected no significant differences in microbiological profiles. However, following addition of FSP to Gochujang, the color was affected and antioxidant properties were enhanced. The DPPH radical scavenging activity of FSP-Gochujang increased by 58.8% and 24.8% compared with Commercial Gochujang and Gallic-Gochujang, respectively. Furthermore, analysis of the free amino acid content revealed higher levels of ${\gamma}$-Aminobutyric acid (100.9 mg/100 g), a biofunctional ingredient, in FSP-Gochujang. Thus, these results suggest the potential for development of a traditional Korean fermented food with enhanced antioxidant activity and ${\gamma}$-Aminobutyric acid content using FSP.
