세계적으로 버섯에 대한 소비는 매년 증가하고 있으며 한국에서는 느타리버섯, 양송이버섯, 팽이버섯이 주로 유 통되고 있다. 하지만, 버섯의 재배와 가공 과정에서 미생 물 오염을 예방하기 위한 대안의 부재로 인하여 Listeria monocytogenes와 같은 병원성 미생물의 오염이 검출되고 있으며 버섯에 의한 식중독 및 리콜 사례가 다수 보고되 고 있다. 버섯에서 오염된 미생물을 저감화하는 방법으로 는 화학적 및 물리적 처리, 또는 이들을 결합하여 사용하는 병용처리 방법이 이용되고 있다. 화학적 처리로는 염소 혼 합물, 과산화아세트산, 4차 암모늄이온 화합물이 주로 사용 되고 있으며 오존과 전해수를 이용한 방법도 최근에 개발 되었다. 물리적 처리로는 초음파, 방사선조사, 콜드 플라즈 마 기술이 이용되고 있으며, 병용처리 방법으로는 자외선/ 염소 혼합물, 오존/유기산, 초음파/유기산 등이 연구되었다. 본 리뷰에서는 국내에서 소비되는 버섯의 종류와 그에 대한 미생물 오염도를 조사하고, 버섯에 오염된 미생물을 제 어할 수 있는 기술에 대하여 조사하여, 정리하였다.

This study established the optimal conditions of noodles by varying the amount of modified starch treated with octenyl succinic anhydride in wheat starch. It investigated the digestibility and quality characteristics of the produced noodles. The color difference of the noodles added with octenyl-succinic anhydride (OSA)-modified starch increased as the amount of OSA-modified starch added increased but decreased after cooking. The cooking characteristics of noodles added with OSA-modified starch showed increased weight, water absorption, and turbidity but reduced volume. In the extensibility of noodles, the noodles with 10 and 20% OSA-modified starch showed the most similar values to the control. The digestibility of noodles with OSA-modified starch added showed a higher RS content as the amount of OSA-modified starch added increased. However, it is considered that an optimal addition level of 20% of modified starch is suitable for the formation of noodle texture. As a result of this study, it is thought that OSA-modified starch, with its low digestibility, could be utilized not only in noodles but also as a low-calorie food ingredient that can replace wheat flour.

This study aims to select eggplant cultivars adaptive to the hot temperature period greenhouse climate by water consumption, and growth performance of plants and fruits of different European eggplant cultivars, including ‘Bartok (BA)’, ‘Bowie (BO)’, ‘Black Pearl (BP)’, ‘Ishbilia (I)’, ‘Mabel (M)’, ‘Vestale (VE)’ and ‘Velia (VL)’, in substrate hydroponic cultivation under hot and humid greenhouse conditions. On the 118 DAT, the leaf number and stem dry weight were highest in ‘VL’, followed by ‘M’, and there was no significant difference in leaf dry weight among cultivars. The marketable fruit number per plant was 16.4 for ‘M’, which was higher than other cultivars, and ‘VE’ and ‘VL’ were 8.5 and 8.8, respectively. The weight per fruit was low for ‘M’ at 136 g, and the highest in ‘VE’ and ‘VL’ at 332 and 281 g, respectively. There was no significant difference in fruit production per plant. In this study, ‘M’, which has high water use efficiency and a large number of fruits, and ‘VL’, which required less quantity to water consumption for producing 200 g of fruit and had a high product weight, will have excellent adaptability in the UAE greenhouse condition.

A beverage was developed using the Abeliophyllum distichum leaf (AL). The beverage was prepared by adding it to apple juice by concentration, and physicochemical quality, antioxidant activities, and sensory evaluation were measured. Soluble solid and reducing sugar content of the control were 12.57 °Brix and 11.40%, respectively, and there was no difference from the group with addition of the AL extract. However, pH was slightly increased upon addition of AL extract. Lightness and yellowness increased when AL extract was added. Verbascoside content was not detected in the control, but it increased as the concentration of AL extract increased. The contents of ascorbic acid and flavonoids were 5.38 and 20.42 mg%, respectively, and there was no significant difference between the groups. However, the content of polyphenols increased as the concentration of the AL extract increased. DPPH radical and metal ion scavenging activity were increased by addition of the AL extract, but there was no difference in the ABTS radical scavenging activity. As a result of the sensory evaluation, there was no difference from the control even wihen the AL extract was added; thus, it was considered that there was no problem with the degree of acceptability when added within about 300 ppm.

To enhance the efficacy of Abeliophyllum distichum leaves, extracts were prepared using different solvents for hydrolytic enzyme-treated Abeliophyllum distichum leaves. Physicochemical quality and antioxidant activity were measured. Soluble solids, reducing sugar, ascorbic acid, flavonoids, and polyphenols contents showed the lowest values in the control without enzyme treatment. However, they showed high contents in ethanol extract. In the case of enzyme treatment, their values were higher than those of the control. In particular, verbascoside content increased about 220 times more than that of the control group when treated with enzymes and extracted with 50% ethanol. pH was lowered upon enzymatic treatment. Regarding DPPH radical scavenging activity, for enzyme-free, 25% ethanol extract showed the highest activity among extracts with different solvents. For cellulase and pectinase-treated leaves, water extract showed the highest DPPH radical scavenging activity among extracts with different solvents. For leaves treated with enzyme combination, 50% ethanol extract showed the highest DPPH radical scavenging activity among extracts with different solvents. Regarding ABTS radical scavenging activity, it was generally higher in the 50% ethanol extract than in the water extract and 25% ethanol extract. In particular, verbascoside content was increased when the extract was prepared by co-treatment with enzymes and 50% ethanol.

This study investigated the potential role of dietary factors associated with obesity and metabolic syndrome (MetS) in Koreans. The scoping review method was used to evaluate the studies that utilized the secondary data sets comprising the Korean National Health and Nutrition Examination Survey (KNHANES) and the Korean Genome and Epidemiology Study (KoGES). Articles published between 2012 and 2022 were identified using RISS, KISS, DBpia, PubMed, and ScienceDirect databases. In all, there were 32 published articles on obesity and 119 on MetS. Obesity research included eight articles on nutrients, 12 on food items/food groups, two on dietary patterns, nine on dietary behavior/eating habits, and one on the dietary index. MetS studies comprised 34 articles on nutrients, 43 on food items/food groups, seven on dietary patterns, 25 on dietary behavior/eating habits, and 10 on the dietary index. Carbohydrates, alcohol, and coffee consumption were the most frequently studied dietary factors for obesity and MetS. The primary areas of study were largely focused on nutrients and food items/food groups. Thus, to overcome the paucity of information on the relationship of dietary patterns and dietary indexes with obesity and MetS, there is a need for further research using the KNHANES and KoGES data sets.

본 연구는 헬스케어 식물 생산단지에 대한 일반 시민들의 인식 및 이용행태를 분석하고, 이용 경험자와 미이용자에 대한 중요도, 만족도 분석을 통해 향후 활성화 방안 및 개선 방향을 도출하였다. 이를 위해 선행연구 분석 및 전문가 브레인스토밍을 통해 헬스케어 식물 생산단지의 주요 요소를 도출하였으며, 전국 성인남녀 1,000명을 대상으로 인터넷 조사를 실시하였다. 또한 조사 결과를 토대로 헬스케어 식물 생산단지의 주요 요소에 대한 만족도와 중요도 기준IPA 분석을 실시하였다. 그 결과 헬스케어 식물 생산단지에 대한 인지수준 및 방문률이 높지는 않으나, 환경 인식 측면에서 생활수준의 향상 속에 환경개선이나 건강관리의 중요성이 강조되면서 헬스케어 식물 개념에 대한 공감대가 비교적 높게 형성되어 있기 때문에 기본적인 시장 수요를 가지고 있는 것으로 확인되었다. 이용 경험자와 미이용자 모두 헬스케어 식물 생산단지의 중요도 및 긍정적인 역할에 대해 공감하고 있으며, 이용 경험자 인식 조사 결과 향후 헬스케어 식물 생산단지의 활성화를 위해서는 기본적으로 화훼나 묘목 관리를 우선으로 하며 다양한 친환경 프로그램 및 시설 개발, 이용자 편의 측면에서의 개선이 필요한 것으로 나타났다. 미이용자 인식 조사 결과 시설 이용 시 편의성에 대한 일부 우려가 있으나 향후 의용의향이 충분한 것으로 나타났으며, 관람이나 친환경 체험 등에 대한 기대감이 크기 때문에 전시시설이나 체험 프로그램 개발 및 홍보가 요구된다. 본 연구의 결과는 헬스케어 식물 생산단지 및 기존 화훼 농가의 발전 방향 제시 등의 기초 자료로 활용 될 것으로 기대되며, 향후에는 헬스케어 식물 생산단지의 주요 요소별 시설 도출 및 설계 방안 등의 연구가 수행되어야 할 것이다.

Owing to its excellent nutritional value, eggs are among the most important components of the human diet. Gender and environmental factors, such as feed composition, may alter the nutritional profile and quality of eggs. Feed additives have recently been used to enhance the health and productivity of hens, which has resulted in the production of higher-quality eggs. The fungus Cordyceps militaris, a well-established source of traditional medicines, contains potential bioactive metabolites, which prompted us to examine the effects of C. militaris-supplemented diets on the quality of hens’ eggs. The hens of two species (Gallus gallus domesticus and Araucana) were fed with one of three different diets: a control diet and diets supplemented with 2% or 5% of C. militaris. Egg quality was determined by measuring the Haugh Unit, yolk color, and shell thickness. In addition, egg and shell densities together with the ratio of yolk to albumen were calculated. Eggshell thickness and yolk color were both enhanced by the addition of C. militaris, whereas Haugh Unit values were somewhat reduced. Egg size, eggshell weight, and yolk and albumen production were all enhanced by C. militaris supplementation. Notably, in hens fed the 2% C. militaris-supplemented diet, enhancement was more evident in the yolk than in the albumen. The overall quality of the egg yolk was enhanced when 2% C. militaris was added to the hens' diet, which led to increases in both yolk color and quantity. Eggshell thickness and weight were also higher among eggs laid by hens fed the supplemented diets. Although these effects differed depending on the chicken species, we established that, in general, C. militaris contributes to improving egg quality.
