식품 사기는 글로벌 식품 공급망에 상당한 위협을 가하 며 경제적 안정성과 공중 보건에 영향을 미친다. 이 리뷰 에서는 먼저 식품 사기 취약성 평가(food fraud vulnerability assessment, FFVA)를 조사하여 다양한 기관의 통합된 정 의와 분류를 통한 표준화된 방법론의 필요성이 강조되었 다. 네 가지 주요 FFVA 도구인 ‘United States Pharmacopeia (USP) 식품 사기 완화 지침’, ‘International Featured Standards (IFS) 표준 제품 사기’, ‘SSAFE 식품 사기 취약 성 평가 도구’, ‘미국 Food and Drug Administration (FDA) 와 United States Department of Agriculture (USDA) criticality, accessibility, recuperability, vulnerability, effect, and recognizability plus shock (CARVER+Shock) 도구’의 주요 특징과 한계점 등을 살펴보았다. 또한 Safe Supply of Affordable Food Everywhere (SSAFE)의 식품 사기 취 약성 평가 도구를 적용하여 우유, 향신료, 오일, 유기농 식 품, 육류, 해산물 및 알코올의 공급망에 대한 취약성 평가 사례를 살펴보았다. 그 결과, 취약성을 평가할 때 원자재 나 제품이 브랜드 또는 상표 위조에 덜 취약한 경우 평가 설문에서 위조 관련 질문을 제외하는 등 식품 공급망 특 성이나 조사 대상에 따라 평가 항목이 조정되었다. 또한 식품 사기 행위의 기술적 탐지 난이도, 기업의 윤리적 문 화, 모니터링 시스템의 구축 정도가 식품 사기 취약성에 상당한 영향을 미치는 것으로 나타났다. 현재 이러한 평 가도구들은 귀중한 프레임워크를 제공하지만, 식품 사기 의 진화하는 본질을 해결하기 위해 보다 통합적이고 적응 가능한 접근 방식이 필요하다는 점이 시사되었다. 식품 사 기 예방을 위한 강력하고 글로벌한 표준을 수립하기 위해 서는 향후 FFVA 방법론을 개선하고 산업, 규제 기관 및 학계 간의 협력이 보다 강화되어야 할 것이다.

본 연구는 아메리카동애등에(Hermetia illucens)의 대량 사육을 위하여 남은음식물 사료의 최적 수분 함량과 적정 사육 밀도를 조사하였다. 실 험에서는 500 g의 습식 사료의 수분 함량을 각각 30%, 50%, 70%, 90%로 조정한 후, 3,500마리의 3령 유충을 7일 동안 사육하였다. 그 결과, 90% 수분 함량에서 평균 유충 무게는 7.19 g으로 측정되었고, 70% 수분 함량에서 가장 높은 무게인 10.54 g이 나타났다. 반면, 50%와 30% 수분 함량에 서는 유충 생육이 저조한 결과가 나타났다. 적절 사육 밀도를 조사를 위해 100,000, 150,000, 200,000, 250,000 마리의 3령 유충을 70% 수분함량 의 100 kg 습식 사료에 7일 동안 처리하였다. 그 결과, 250,000 마리에서 총 유충 생산량이 22.79 kg으로 가장 높게 나타났으나, 150,000, 200,000, 250,000 마리 밀도 간에는 유의미한 차이가 없었다. 100마리당 평균 무게는 100,000 마리에서 16.90 g, 150,000 마리에서 15.20 g, 200,000 마리 에서 11.30 g, 250,000 마리에서 9.50 g으로 확인되었으며, 100,000 마리와 150,000 마리 밀도 간에는 유의미한 차이가 없었다. 결론적으로, 남은 음식물 사료인 습식사료 100 kg를 급여할 경우 수분 함량을 70%로 유지하고 사육 밀도를 15만 마리로 설정하는 것이 가장 효과적임을 확인하였다.

This study analyzed the status of agrifood consumer competencies and the factors influencing them to provide useful information to improve the quality of life by strengthening the agrifood consumer competencies. The raw data of the 2022 Consumer Behavior Survey for Food collected by the Korea Rural Economic Research Institute were used. The data from 3,321 responses were used for the final analysis. Among the competencies, the average score of the cognitive and practical competencies were 3.543 and 3.459 points, respectively. In addition, the average scores of the specific areas within cognitive competency were 3.587 points for dietary competency, 3.557 points for civic competency, and 3.489 points for purchasing competency. Within practical competency, the average scores of the specific areas were 3.569 points for dietary competency, 3.422 points for civic competency, and 3.392 points for purchasing competency. Gender, age, monthly household income, marital status, administrative district, interest in health, and interest in food safety issues were the significant factors affecting the specific areas within cognitive competency. On the other hand, gender, age, educational level, monthly household income, marital status, administrative district, interest in food safety issues, and each of the areas within cognitive competency had a significant impact on the specific areas of practical competency.

This study examined domestic consumption trends in the development of mushroom-based alternative food products. It found that 85.5% of consumers were aware of alternative foods, with a higher recognition rate among younger age groups and variations based on household composition and monthly income. Additionally, 70% of consumers familiar with alternative foods had tried them. Among those who had not, taste (16%) and purchasing challenges (15%) were the primary barriers. Minced meat was the most commonly consumed alternative (25%), while dumplings (7%) and burgers (1%) were less popular. Notably, dumplings and burgers showed the highest potential for development using mushroom-based ingredients. These findings provide valuable foundational data for advancing mushroom-based alternative food products.

The purpose of this study was to compare and analyze dietary self-efficacy and Nutrition Quotient (NQ) according to the degree of food-related content use in university students. From October to November 2022, a total of 332 college students (140 males and 192 females) attending universities in Chungcheongbuk-do were surveyed to collect data on general information, food-related content use level, dietary self-efficacy, and NQ for adults. The average dietary self-efficacy score of the group that did not use food content was 3.08 points, which was significantly higher than the group that watched it sometimes (2.89 points) and the group that watched it often (2.83 points) (p=0.0191). The total NQ score of 48.85 points was the highest among the three groups (p=0.0270). For subjects who responded that they had no experience of eating food at all after using food content, their dietary self-efficacy was 3.03, which was significantly higher than the group with occasional or frequent food consumption experience (p=0.0194). Results of this study can be used as basic data for clarifying the relationship between the use of food-related content and eating habits in university students and for proper eating habits education for university students.

Recently, ESG(Environmental, Social, Governance) has been recognized as an important factor for the sustainable growth of companies. However, only 14.5% of food manufacturing companies have adopted ESG management. In particular, small and medium-sized enterprises(SMEs) face difficulties in implementing ESG management due to a lack of specialized personnel and resource constraints. The purpose of this study is to analyze the impact of ESG ratings on the management performance of 40 food manufacturing companies listed on the Korea Exchange(KRX) that have been evaluated for ESG. The one-way ANOVA was used and performed on data for 40 food manufacturing companies published by the Korea Institute of Corporate Governance and Sustainability(KCGS) in 2023. The results of the analysis showed statistically significant differences in sales (F=12.936, p<0.001) and foreign ownership (F=7.74, p<0.01) based on ESG ratings. Furthermore, Scheffe's post-hoc analysis indicated that the higher the ESG rating and individual scores, the better the overall management performance. Therefore, it is concluded that food manufacturing companies should continuously invest in and focus on ESG management to secure a competitive advantage in the market and achieve sustainable growth.

Habitat environment and food sources of fish, benthic macroinvertebrates, and brown trout (Salmo trutta) downstream of Soyang River Dam were analyzed. Water temperature at the site where brown trout was identified ranged from approximately 12.4 to 13.4°C, confirming that this environment could provide an optimal water temperature for the growth of brown trout. Most of the riverbed structures at this site had a high proportion of cobble and pebble substrates. Brown trout constituted less than 5% of the total fish population, more abundant in the upstream. The total lengthweight relationship of brown trout showed a parameter b value of 3.234, with the condition factor (K) increasing with length. Dominant benthic macroinvertebrates were Limnodrilus gotoi and Chironomidae spp. (non-red type). Stomach content analysis indicated that brown trout primarily consumed aquatic insects (R.A., 73.8%), non-insects (R.A., 23.3%), ground insects (R.A., 2.7%), and fish (R.A., 0.2%, TL: 246 mm). Correlation analysis revealed a positive relationship between total length and species preferring flowing water (p<0.05) and a negative relationship of total length with species favoring low-flow, sandy habitats (p<0.05). Larger brown trout showed active feeding behavior and resilience to flow speed and riverbed structure. The primary food source for the largest brown trout (TL: 246 mm) was Hypomesus nipponensis. Future analyses should include brown trout with a total length of 30 cm or more. Given that samples were limited, comprehensive population management will require ongoing research.

This study conducted field surveys targeting benthic macroinvertebrates and fish in Andong Dam and Yeongsan River, with the specific aim of analyzing bluegill stomach contents. Bluegills in Andong Dam ranged from 40-220 mm, with 93.0% between 80-220 mm, while those in Yeongsan River ranged from 50-210 mm, with 71.4% between 120-210 mm. The highest feeding rates in both sites were for Chironomidae spp., with findings of 72.6% in Andong Dam and 80.4% in Yeongsan River. In Andong Dam, H. nipponensis and Baetidae sp. were also significant at 17.5% and 6.5%, respectively, while in Yeongsan River, Baetidae sp. (7.5%) and Hymenoptera sp. were the next most common at 3.8%. The EI index showed that bluegills generally avoided H. nipponensis and S. tsuchigae (-0.373 and -0.975) whereas they preferred Chironomidae spp. (0.759, 0.892) and Baetidae sp. (0.723). The parameter b values of the total length-weight relationship of bluegill were calculated as 3.452 in Andong Dam and 3.449 in the Yeongsan River, respectively. The slope values of the condition factor were 0.0067 in Andong Dam and 0.0065 in the Yeongsan River. Both values were positive, indicating that the nutritional status of bluegill was good. Aquatic insects constituted the primary food source, particularly in Yeongsan River. Feeding patterns did not significantly differ by habitat orientation groups, but Yeongsan River bluegills consumed more diverse food sources. In Andong Dam, larger bluegills likely consume food sources with larger biomass, while Yeongsan River’s diverse and abundant food sources support opportunistic feeding tailored to the water ecological environment.

The purpose of this study was to quantitatively analyze the food security situation in Cuba using the National Food Security Index (NFSI) and compare it with neighboring countries with geographic and environmental similarities in order to provide policy implications for strengthening food security in Cuba. According to the analysis, Cuba’s food security level is in the NFSI Red Level. It is one of the lowest in the Latin American and Caribbean (LAC) region. Analysis of factors affecting food security levels showed that extreme weather events (i.e. high temperatures, heavy rainfall), political instability, and uncertainties such as the COVID-19 pandemic were the main factors threatening food security in 9 LAC countries, including Cuba. Results of this study can be used as a basis for diagnosing and strengthening the food security situation in Cuba. They will be helpful for future international cooperation and linkages between Cuba and Korea, including food aid and agricultural technology cooperation.

In this paper, we aim to improve the output quality of a food 3D printer through optimized component design and implementation. Existing 3D printers produce customized outputs according to consumer needs, but have problems with output speed and poor quality. In this paper, we aim to solve this problem through optimized design of unit parts such as the extruder, nozzle, guide, and external case. Fusion 360 was used for element design, and in the performance evaluation of the implemented system, the average precision was 0.06mm, which is higher than the non-repeatable precision of ±0.1㎜ of other products, and the feed speed of the existing system was evaluated to be more than twice as fast, from 70mm/s to 140mm/s. In the future, we plan to continuously research output elements that can produce texture and color and device control methods for convenience.

많은 사람들이 건강과 동물보호를 위한 채식에 관심이 있지만, 채식을 실천하는 것은 쉽지 않다. 본 연구에서는 한 개인의 마음-신체의 관계에 대한 생각이 건강을 위한 행동과 채식제품의 선택에 끼치는 영향을 살펴보려 한다. 연구 1에서는 마음-신체의 관계에 대한 생각을 마음-신체가 분리되는 이원론과 마음-신체가 연결되는 물리주의로 구분하여, 이 두 가지 유형의 생각이 건강을 위한 행동과 채식제품의 선택에 끼치는 영향을 비교하였다. 연구 2에서 는 마음-신체에 대한 생각이 한 개인이 지향하는 사회적 가치에 영향을 끼치는지를 검증하였다. 연구 3에서는 건강 한 채식과 이원론의 관계가 양방향으로도 가능한지를 건강한 음식사진과 건강하지 않은 음식사진을 점화하여 검증 하였다. 그 결과 연구 1에서는 마음-신체의 이원론조건에서 마음-신체가 연결되는 물리주의 조건보다 건강을 위한 행동의향이 더 낮게 나타났다. 연구 2에서는 이원론조건에서 채식제품의 선택의향과 배려의 가치선호도가 더 낮게 나타났다. 연구 3에서는 건강하지 않은 음식조건에서 건강한 음식조건보다 이원론의 점수가 더 높게 나타났다. 이 결과는 마음-신체의 관계에 대한 개인의 생각이 건강을 위한 행동과 사회적 가치의 활성화에 차별화된 영향을 끼칠 가능성을 보여준다.

The alternative food market has attracted much attention due to concerns about climate change, increasing consumer awareness of value consumption, and the development of the Food-Tech industry. This study aimed to analyze the factors that drive consumers to purchase alternative food products and identify the mechanisms that can induce consumers to continue buying. We surveyed 1,200 consumers and estimated data using a logit model. The results showed that the presence of vegetarians in the household, environmental concerns, a vegetable-oriented diet, and a mixed diet of meat and vegetables were positively associated with purchasing plant-based alternatives. Of particular interest was the non-linear relationship between respondents’ age and their purchasing experience with plant-based options, with the likelihood of purchasing alternatives increasing with age from the mid-50s onward. These findings suggest that in addition to the growing number of consumers who share the environmental value, which leads to increased interest in and purchase of plant-based alternatives, alternative foods are also health-oriented and meet the needs of older consumers, who are becoming an increasingly important segment of the super-aged society, suggesting the potential for continued growth in the alternative food market.

This study aims to develop a deep learning model to monitor rice serving amounts in institutional foodservice, enhancing personalized nutrition management. The goal is to identify the best convolutional neural network (CNN) for detecting rice quantities on serving trays, addressing balanced dietary intake challenges. Both a vanilla CNN and 12 pre-trained CNNs were tested, using features extracted from images of varying rice quantities on white trays. Configurations included optimizers, image generation, dropout, feature extraction, and fine-tuning, with top-1 validation accuracy as the evaluation metric. The vanilla CNN achieved 60% top-1 validation accuracy, while pre-trained CNNs significantly improved performance, reaching up to 90% accuracy. MobileNetV2, suitable for mobile devices, achieved a minimum 76% accuracy. These results suggest the model can effectively monitor rice servings, with potential for improvement through ongoing data collection and training. This development represents a significant advancement in personalized nutrition management, with high validation accuracy indicating its potential utility in dietary management. Continuous improvement based on expanding datasets promises enhanced precision and reliability, contributing to better health outcomes.

2019년부터 2023년까지 서울지역에 유통되는 식약공용 농·임산물 60품목 1,340건을 대상으로 ICP-MS와 수은분 석기, 모니어-월리엄스 변법을 사용하여 중금속(납, 카드 뮴, 비소, 수은) 및 이산화황의 함량을 조사하고 위해성 평 가를 수행하였다. 중금속의 평균 검출량 및 범위는 납 0.327 mg/kg (ND-36.933), 카드뮴 0.083 mg/kg (ND-1.700), 비소 0.075 mg/kg (ND-2.200), 수은 0.004 mg/kg (ND- 0.047)으로 나타났다. 품목별은 2023년에 복령 1건에서 납 이 36.933 mg/kg으로 기준을 초과하였고 카드뮴은 2022년 에 구절초 2건이 각각 1.700 mg/kg, 0.650 mg/kg으로 기준 를 초과하였다. 나머지 품목은 모두 허용기준 이내였다. 이 산화황의 평균 검출량 및 범위는 0.75 mg/kg (ND-192.00)이 였으며, 2019년에 천마 2건에서 각각 192.00 mg/kg과 42.00 mg/kg으로 기준치을 초과하였다. 약용부위별 중금속 평균 검출량은 납은 버섯류(1.377 mg/kg), 카드뮴은 수·근피 류(0.156 mg/kg)와 등목류(0.144 mg/kg), 비소는 엽류 (0.149 mg/kg), 수은은 전초류(0.009 mg/kg), 엽류(0.009 mg/ kg)에서 높게 검출되었다. 이산화황 평균 검출량은 근경류 (4.12 mg/kg)에서 높게 검출되었다. 원산지별로 중금속 및 이산화황 함량을 비교한 결과, 납, 카드뮴 및 수은은 국내 산, 중국산, 중국 외 수입산 간에 차이는 없었으나, 비소 와 이산화황은 중국산이 국내산과 중국 외 수입산보다 높 게 검출되었다. 위해성 평가 결과, 납은 대부분의 품목에 서 노출안전역(MOE)값이 1보다 커서 인체 위해성이 낮았 지만, 복령에서 MOE 값이0.66으로 1보다 낮아 위해성이 있는 것으로 나타났다. 카드뮴, 비소 및 수은의 위해도(HI) 는 각각 0.2740-1.0702%, 0.0049-0.0335% 및 0.0041- 0.0287%로 매우 낮은 수준으로 평가되었다. 이산화황의 위해도(HI)는 모든 품목에서1을 초과하지 않아 안전한 수 준이었다. 앞으로도, 식약공용 농·임산물의 안전성에 대한 지속적인 관심과 모니터링이 필요하다.

This study investigated the operating principles of colorimetric freshness indicators, particularly those for relative humidity (RH) and hydrogen sulfide (H2S), and evaluated the applicability of commercially available indicators for food use. The findings not only provide a deeper understanding of how these indicators respond to substances, such as carbon dioxide, volatile basic nitrogen, sulfides, water activity, and ethylene gas, which are produced during quality changes in food, but also pave the way for the development of new food safety technologies. The RH indicator functions by utilizing a dye that undergoes a chemical structural change when reacting with moisture. The H2S indicator uses a dye that changes color upon detecting H2S or volatile basic nitrogen produced when food spoils. Commercial RH indicators effectively indicated changes in the water activity of almonds, pastries, and red pepper powder; however, their ability to predict them diminished during storage. Commercial H2S indicators exhibited a stronger correlation between color change and volatile basic nitrogen levels in exposure to light than without light, as demonstrated when applied to mackerel and clam. Additionally, at the point of spoilage, the degree of color change in the H2S indicators was more distinct in clam than mackerel. Although commercial RH and H2S indicators are available, they must be sensitive, accurate, and irreversibly developed in response to changes in the target food for effective application.

As the number of households with pets has increased worldwide, there is a growing trend of accepting pets as family members. Consequently, the pet food market has seen the emergence of concepts such as “human-grade,” “raw (PMR and BARF),” and “no synthetic additives” pet food. These concepts not only fulfill essential nutrients but also consider the health and habits of pets, a crucial aspect that should be at the forefront of our work. However, these types of pet food are prone to microbial contamination and component alterations caused by heat. Current studies and products have recently been developed overseas to apply non-thermal sterilization technologies to pet food commonly used in the food industry. In contrast, the domestic standards for non-thermal sterilization in pet food are insufficient. Therefore, a comprehensive review of non-thermal sterilization technologies, such as high-pressure processing (HPP), radiation, and plasma predominantly applied in the international pet food market, is deemed necessary. This review is expected to provide guidelines for non-thermal sterilization standards in domestic pet food, thereby laying the foundation for the safe production of raw pet food.
