본 연구는 2018년 10월에서 2019년 9월까지 부산지역 유통 판매되고 있는 872건의 다양한 식품을 대상으로 B. cereus 오염도를 분석하였다. 총 872건 중 78건(8.9%)에서 B. cereus 검출되었으며 식품별 B. cereus 검출률은 김치· 절임·조림·젓갈류에서 23.9%, 조미식품 19.4%, 바로 섭취 가능한 농산물 10.5%, 조리식품 7.3%, 즉석섭취식품 5.6%, 신선편의식품 5.0%, 즉석조리식품 0.0% 순으로 분포하였으며 통계적으로 유의한 차이가 있었다. B. cereus 오염 수준은 불검출에서 최대 20,000 CFU/g로 평균 48 CFU/g였으며, 식품별 B.cereus 오염도에는 차이가 없었다. 78건의 검체에서 분리된 113주의 B. cereus의 독소 유전자 확인 시험을 수행하였다. 식품에서 분리된 113주를 대상으로 B. cereus 독소유전자 확인 결과 최소 1종류에서 최대 5종류 의 독소 유전자가 검출되었으며 총 18개 profile로 분류되 었다. 장독소 5종(Cytk-nheA-entFM-bceT-hblC)을 모두 보유한 경우가 34주(30.1%)로 가장 많았다.

Studies with various approaches are required for the globalization of Korean Food. The objectives of this study were i) how the preferences of foreign students residing in Korea on K-Wave, K-Drama, K-Pop and K-Friend affect their preference, satisfaction level and repurchase intention on Korean food, and ii) which of the factors have the strongest effects on their preference, satisfaction level and repurchase intention on Korean food. The results showed that the higher K-Wave, K-Drama, K-Pop and K-Friend preferences, the stronger effect on the preference, satisfaction level and repurchase intention on Korean food (p=0.0001). Among the factors for Korean food preference, the most critical one was K-Wave preference (p=0.0001), followed by K-Drama preference (p=0.0500). For the satisfaction level of Korean food, the most important factor among the four was K-Wave preference (p=0.0496), followed by K-Drama preference (p=0.0500). For the repurchase intention on Korean food, the most significant factor was the preference for K-Friend (p=0.0004), followed by K-Drama (p=0.0016) and K-Wave (p=0.0030). Based on these results, more efforts to invigorate the preferences for K-Wave and K-Drama, as well as various attempts to improve the preference for K-Friend are required for the globalization of Korean Food.

This study surveyed the recognition, image, preference, attributes, satisfaction and revisit intention for Korean food of local Vietnamese to facilitate the globalization of Korean food. Most participants had recognized Korean food. and, they were especially aware of kimchi (김치), bulgogi (불고기) and bibimbab (비빔밥), Additionally, most repondents thought these foods represent Korean traditions and culture very well.

In addition, the local Vietnamese showed a very high revisit intention for Korean food.

In the view of the fact that data are scare concerning the change of Methionine composition of poultry meat in function of storage temperature and cooking method. The present study was carried out to change in these compounds and the results were summarized as follows. 1. The result of measuring methionine compound of raw material stored under the condition of 5℃, 10℃ for 6 weeks were increased as temperature increases. 2. The result of change in methionine compound of roasting were decreased than raw material It was greatly decreased in the storage for 42 days at 10℃ and slightly decreased in the storage for 14 days at 5℃ 3. When the boiling in the water, methionine compound was decreased than roasting to compare with raw material 4. By the results of this study, one of the best cooking method is roasting, because of the change in methionine compound of roasting is slightly decrease.
