There is a strong connection between the diet rich in antioxidants and the decreased incidence of cardiovascular and cancerous diseases. Diets that are rich in anti-oxidants particularly include fruits and vegetables containing the high amounts of vitamin A-E, carotenoids, and minerals. Different processing conditions applied for vegetables and plants results in the alteration of the nutrients present in them. Therefore the rationale of our study was to compare the antioxidant effects of different processed vegetables and plants and to see that which one of them showed best anti-oxidant activity. For this purpose, we have used acetaminophen induced oxidative stress model in mice to check the effects of processed apple, pear, carrot, cabbage, broccoli and radish. Our results have shown that the administration of these samples effectively decreased the expression of parameters related with oxidative stress like ALT, AST, catalase, superoxide dismutase, GPx and 8-OHdG. Moreover they also significantly protected the mice livers from APAP induced damage as shown by histological changes. Therefore our results have demonstrated the effects of processed fruits and vegetables in mice model of oxidative stress.

최근 5년간 단기소득임산물 생산량 및 생산액은 증가하고 있는 추세이며, 그 중에서도 산채(산나물) 생산액은 2017년 기준 약 4천억 원으로 전체의 14 %를 차지하고 있다. 산채 중에서도 특히 고사리, 취나물, 곤드레 등의 생산량 및 생산액은 꾸준히 증가하고 있지만, 산나물의 특성상 값 싼 수입산과의 가격경쟁이 심하고, 소비패턴의 변화가 거의 없는 점들로 인해 국내산 산채류 가격에 악영향을 미치고 이는 결국 산채 소비시장의 전반적인 소비 위축 현상을 불러일으킬 위험이 있다. 하지만 최근 소득수준의 향상과 건강에 대한 소비자들의 관심도가 증가함에 따라 건강에 좋은 웰빙 식품 선호 현상이 나타나고 있어, 지금이 산채 소비시장에서는 매우 중요한 시점이라고 할 수 있다. 이에, 본 연구에서는 산채 소비활성화를 위한 다양한 전략 및 정책 수립에 도움이 되기 위하여 소비자조사를 통한 산채에 대한 소비자들의 구매행태 및 소비행태를 분석하였고, 이와 더불어 소셜 빅데이터 분석을 통하여 산채에 대한 소비자 인식 및 의향을 파악하였다. 기존 연구들과는 달리 설문조사뿐만 아니라 SNS 소셜 빅데이터 분석을 통한 소비자 인식 및 의향 조사도 실시했다는 점에서 차별성이 있으며, 본 연구 결과가 향후 산채 소비 증진을 위한 전략 및 정책 마련에 있어 우선순위를 정하는데 도움이 될 것으로 판단된다.

This survey was conducted to assess the perception of hazards and washing behavior of vegetables of 500 housewives in Korea. The subjects were selected by the stratified random sampling method. The survey was performed using a structured questionnaire through telephone interviews by skilled interviewers. Most people have bought vegetables and fruits in the supermarket or (traditional) markets rather than stores, department stores, or direct transactions. Eighteen percent of the subjects felt vegetables were secure and were not concerned about safety. But $42.8{\%}$ were concerned about vegetable safety. The perceptions of vegetable-related hazards differed significantly by the respondent's socioeconomic characteristics. Higher concern about vegetable safety was reported by subjects with higher income, children, and who usually buy vegetables in supermarkets or department stores. Most subjects ($88.6{\%}$) perceived that residues of chemical substances such as pesticides were the most significant potential vegetable risk factor, followed by heavy metal, and pathogens. Housewives mainly rinsed vegetables in flowing-water ($85.2{\%}$ of subjects), 3${\~}$4 times ($63.8{\%}$ of subjects), and without detergent ($90.6{\%}$). Subjects believed that hazards decreased by blanching or boiling vegetables rather than washing. Subjects realized more or less correctly the removal rate of pesticide and pathogen through the washing and cooking processes. However, the removal rate of heavy metals was less than subjects thought it would be. Therefore, the scientifically assessed results on safety in the washing and cooking process should be opened to the public to provide the right-to-know and assure confidence in consumers.

Cryptosporidium and Cyclospora are well-known coccidian protozoa that can cause waterborne and food-borne diarrheal illnesses. There have been a few reports regarding contamination in different vegetables with Cryptosporidium, but no data are available regarding the sources of Cyclospora infections in Korea. In the present study, we collected 6 kinds of vegetables (perilla leaves, winter-grown cabbages, chives, sprouts, blueberries, and cherry tomatoes) from July 2014 to June 2015, and investigated contamination by these 2 protozoa using multiplex quantitative real-time PCR. Among 404 vegetables, Cryptosporidium and Cyclospora were detected in 31 (7.7%) and 5 (1.2%) samples, respectively. In addition, Cryptosporidium was isolated from all 6 kinds of vegetables, whereas Cyclospora was detected in 4 kinds of vegetables (except perilla leaves and chives). Cryptosporidium (17.8%) and Cyclospora (2.9%) had the highest detection rates in chives and winter-grown cabbages, respectively. Cryptosporidium was detected all year long; however, Cyclospora was detected only from October to January. In 2 samples (sprout and blueberry), both Cryptosporidium and Cyclospora were detected. Further investigations using TaqI restriction enzyme fragmentation and nested PCR confirmed Cryptosporidium parvum and Cyclospora cayetanensis, respectively. In conclusion, we detected C. cayetanensis in vegetables for the first time in Korea. This suggests that screening should be employed to prevent these protozoal infections in Korea.

To investigate the antimicrobial activity on bacteria causing a respiration disease and antioxidant effects of water extracts from 12 kinds of wild edible vegetables, we extracted the water extracts for 72 h in $7^{\circ}C$ using distilled water as solvent. The water extracts except Ixeris dentate and Allium monanthum had high concentrations of phenol compounds and flavonoids. Liguraia fischeri specially had the highest level on total phenol compounds and flavonoids with 205 ${\mu}g/mL$ and 98. 86 ${\mu}g/mL$, respectively. The each 0.05% extracts of Sedum sarmentosum and Liguraia fischeri had high effect on the DPPH radical scavenging activity among wild edible vegetables and the most extracts promoted antioxidant activity with increasing concentration of extract. The catalase activity of Erysimum aurantiacum and Aralia elata showed more than 150 units per g of fresh tissue. The effect of antimicrobial activity on water extracts showed characteristic activity. Only Staphylococcus aureus KCTC 1928 and Corynebacterium diptheriae KCTC 3075 were inhibited cell growth on the other hands, the remainder of bacteria was not inhibited cell growth. Nevertheless, the extracts of wild edible vegetables had specific concentration as MIC for antimicrobial activity respectively. In case of the extract of Aster scaber, Erysimum aurantiacum, and Allium monanthum had over 30% antimicrobial activity on the bacteria causing a respiration disease. In results, the wild edible vegetables include high concentrations of total phenol compounds and flavonoids that give a good antioxidant activity and antimicrobial activity. Therefore the wild edible vegetables are functional food for anti-aging and physiological activation.

The soil-transmitted helminthes, such as ascaris, whipworm, hookworm and trichostrongylus, have been considered as the most prevalent parasitic diseases in a matter of several decades ago in Korea. In facts, the attached eggs and/or larvae to the vegetables have been played a great role on the transmission to human because of raw eating the vegetables without the proper recipe. The aims of this study is to outline the attached helminthes egg in vegetables and to define whether the detection rates on them show a decreasing pattern or not in present. The subjected vegetables were collected from the three markets which are located at Goo-Pa Bal, Soo-Yoo Dong, Cheon-Ho Dong in suburban area, Seoul from April to May 1983. A total of 180 samples including such as 60 Korean cabbages, 60 young radishes and 60 Korean onions were examined. For the detection of helminthes eggs, the both methods of formalin-ether sedimentation and zinc-sulfate floatation were applied. The results were summarized as follows: 1) The detected eggs of ascaris, whipworm, hookworm, trichostrongylus and either filariform larvae or rhabditoidform larvae of hookworm, as well as unknown ones were found in vegetables subjected. 2) Out of 180 subjects, the overall detection rate showed 48 (26.7%). And in case of Korean onion, the rate revealed 22 heads (36.7%) among 60, 17 heads (28.3%) out of 60 Korean cabbages, 9 roots (15.0%) out of 60 young radishes respectively. 3) The ascaris eggs were detected 6 heads (10%) out of 60 Korean cabbages, while the filariform larvae of hookworm appeared in 7 heads (11.7%) among 60 Korean onions. 4) In the results of present study, the detection rates in vegetables were appeared to be the marked decreasing tendency as like 28.3%, 36.7%, 15% compared with 96%, 100%, 88% of previous investigators (Choi et al. 1967)each on Korean cabbage, Korean onion, young radish.

The purpose of this study was to investigate effect of methanolic extracts of 10 kinds of wild vegetables cultivated in Gangwon province on antioxidant activity, acetylcholinesterase, and β-secretase inhibitory activities. Results showed that among the wild vegetables, Aralia elata(Miq.) Seem shoot extract exhibited the highest total phenol content (84.65±1.08 mg GAE/g) and total flavonoids content (70.77±0.55 mg RE/g), respectively. The antioxidant activity of wild vegetables extracts was measured by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay. Aralia elata(Miq.) Seem shoot extracts had the highest DPPH and ABTS scavenging activity (90.16%, 40.18% at 2 mg/mL). As a result, Aralia elata(Miq.) Seem shoot extract was the most effective in terms of acetylcholinesterase inhibitory activity (35.94% at 1 mg/mL). In the β-secretase activity assay, all 10 kinds wild vegetables extracts showed low inhibitory activity, and Aralia elata(Miq.) Seem shoot extract had highest inhibitory activity among the 10 wild vegetables extracts was 14.99%. Taken together, these results showed that Aralia elata(Miq.) Seem shoot extract has potential cognition improvement impact, suggesting that it may provide an effective strategy for improving cognition.

BACKGROUND/OBJECTIVES: Fruit and vegetable consumption of children in the United States falls below recommendations. The U.S. Department of Agriculture Fresh Fruit and Vegetable Program (FFVP) is a national free-fruit and vegetable school distribution program designed to address this problem. This permanent, legislated program provides funding to qualified elementary schools for provision of additional fruit and vegetables outside of school meals. The objective of this study was to understand children's perceptions of FFVP after the intervention and formulate recommendations that may improve success of the intervention. SUBJECTS/METHODS: Secondary data were obtained from 5,265 $4^{th}-6^{th}$ graders at 51 randomly-selected FFVP intervention schools in Indiana. Anonymous questionnaires were completed late in the 2011-2012 academic year. Multilevel logistic regressions were used to determine associations between students' perceptions of program effects (4 close-ended items) and their preference toward the program. Content analysis was applied to a single open-ended item for program comments. RESULTS: Over 47% of students reported greater intake of fruit and vegetables due to FFVP, and over 66% reported liking the program. Student-reported program effects were positively associated with preference for the program (P < 0.01). Themes that emerged during analysis of 3,811 comments, included, students liked: the opportunity to try different kinds of fruit and vegetables, types and flavors of fruits served, and benefits of eating fruit. Fewer students liked the types of vegetables and their benefits. A small group disliked the program citing poor flavor of vegetables and quality of fruits. Important suggestions for the program include serving more dipping sauces for vegetables, cooking vegetables, and providing a greater variety of produce. CONCLUSIONS: The degree that students liked FFVP may predict the program's effects on fruit and vegetable intake. FFVP may become more acceptable to students by incorporating their suggestions. Program planners should consider these options for achieving program goals.
