The objective of this study was to investigate the perceptions and purchase behaviors on foreign matters in food. For that, we conducted a survey of 348 adults living in a metropolitan area. Concern over the presence of foreign matters in food was a lower than that for other harmful factors such as heavy metals, BSE, harmful microbes and so on. 70% of respondents would not take the snack which was detected a rat's head, including the manufacturer's product and similar products with it after the foreign matter incident. In contrast, about of 54% respondents were willing to buy canned tuna after the incident. It is necessary to prepare more detail management and policy on foreign matters in food.

Globally, agriculture is one of the largest consumers and polluters of water resources, contributing to the unsustainable use of limited water resources. To reduce the resource use and environmental footprints associated with current and future food systems, researchers and policy makers have recommended the transition to sustainable and healthier diets and the reduction of food loss and waste along the food supply chain. However, there is limited information on the synergistic effects and trade-offs of adopting the two measures. In this study, we assessed the water-saving potential of the two measures in South Korea using environmentally extended input-output relying on the EXIOBASE database for the reference year 2020, along with scenario analysis to model the potential outcomes. Specifically, we analyzed scenarios where meat consumption was reduced by 30% and 50% and in combination with a 50% reduction in food waste at the consumption stage for each scenario. According to our findings, by considering individual measures of dietary change and food waste reduction, shifting to a diet with 30% and 50% less meat consumption could lead to reduction in water footprint by 6.9% and 7.5%, respectively, while 50% reduction in food waste at the consumption stage could save about 14% of water footprint. However, the synergistic effects of the two measures such as 30% less meat consumption and 50% food waste reduction, and 50% less meat consumption and 50% food waste reduction result to 20% and 24% reductions in water footprint, respectively. Moreover, our findings also showed that increasing food consumption with high environmental impacts could promote resources use inefficiency when waste occurs. Thus, policy strategies that address synergistic effects of both dietary change and food waste reduction should be strengthened to achieve sustainable food system. International and national policies can increase resource efficiency by utilizing all available reduction potentials while considering strategies interactions.

The objective of this study is to investigate the perception and satisfaction of elementary and middle school students on free school food service. We surveyed education related to school food service, concerns about food ingredients, perceptions of free school food service and satisfaction for the quality of the school food service. The investigation is classified into two groups, schools that operate as a food service center or those that do not. Those who are provided food ingredients by school food service centers are educated about the agricultural products' country-of-origin and their environment-friendly food service. The more individuals are educated of the foods' county-of-origin and environment-friendly food service the more they will have a higher concern of the food materials and subsequently a higher satisfaction for the quality of school food service. School food service centers managed directly by the local government would probably receive higher satisfaction than those consigned to a private sector. The results of this study will be meaningful to establish policies on school food service and school food service centers.

The objective of this study to investigate the satisfaction of elementary and middle school students in Chungnam province. We surveyed related to school food service, concerns about food ingredients and dietary life, perceptions of free school food service and satisfaction the quality and management of the school food service. Furthermore, this survey with the previous. Compared to year, frequency of education related to school food service and concerns about food ingredients and dietary life. Perception on free school food service increased 1.2%, not statistically significant. Satisfaction for the quality of the school food service statistically significant increase compared to 2015. ore individuals educated the foods' county-of-origin and a higher concern the food materials and dietary life, subsequently higher satisfaction for the quality and management of school food service. The results of this study suggest that concern and concentration on software of school food service such as education and guide are important.

본 연구는 음식물류폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 제시하고자 실시하였다. 현재 운영중인 음식물류폐기물 자원화 시설에 대한 투자에서부터 운영현황 분석을 통해 투자비 대비 경제성이 어느 정도인지의 경제성 분석을 실시하였으며 시설의 무분별한 신규건설로 인한 국가의 예산이 낭비되지 않도록 그 대안을 제시하였다. 그 결과, 공공자원화시설 경제성 확보방안 마련, 공공자원화시설에 대한 국고보조금 지원기준 강화, 음식물류폐기물 단일 독립법안 제정이 필요할 것으로 사료되었다.

본 연구에서는 전분 및 단백질 분해력이 우수한 토착 발효종균 Aspergillus luchuensis 74-5 및 Aspergillus oryzae 75-2로 제조한 고체종국의 품질 특성을 조사하였다. 액체종국 접종량 5%와 10% 접종하였을 때, pH는 각각 5.78 및 3.85 이하로, 적정산도는 2.12와 8.54 이상, 아미노산도는 1.15 및 2.66 이상으로 균주에 따라 차이를 보였다. 효소활성의 변화는 발효종균에 따라 증감 패턴이 특징적으로 나타났고, 액국 접종량에 따라 A. luchuensis 74-5는 접종량이 증가할수록 ${\alpha}-amylase$와 glucoamylase 활성은 증가하나 acidic protease활성은 감소하였고, A. oryzae 75-2는 5% 접종하였을 때 모든 효소활성이 가장 높게 나타났다. 발효온도는 저온보다 중온(35, $40^{\circ}C$)에서 효소활성이 우수한 것으로 나타났고, 발효시간은 종균에 따라 차이는 있지만 각각 144시간과 120시간일 때 효소활성이 높은 것으로 나타났다. 발효조건에 따른 고체종국의 포자수는 약 $2.0{\times}10^7$, 세균의 오염은 약 $3.0{\times}10^3$으로 나타났으며, 세균에 의한 오염도 저감화 및 효소활성을 유지하기 위하여, 구연산, 종국의 건조법 및 부형제 등의 추가적인 연구가 필요하다.
