  • Functional foods are of great significance since our society is accelerating into aging. An aging society has many physiological metabolic diseases such as hypertension, diabetes, heart disease, cancer, dementia and geriatric diseases. Fundamental treatments for the elderly are almost impossible and the social burden is heavy. If these diseases can be prevented or alleviated by improving dietary habits using functional foods, the significance would be very large. Pomegranate has been found to have 124 different kinds of phytochemicals. Polyphenols have a wide range of protective effects including various physiological metabolic diseases and cancers. It is necessary to develop functional foods such as preservatives and food extenders which can contribute to food safety, required in the food industry, by using such bioactive substances. Pomegranates have been reported to decrease the impact of many serious illnesses. There is a considerable amount of bioactive substances in the peel of a pomegranate, which has potent anticancer, antioxidant, antimicrobial and anti-apoptotic properties. Unfortunately, the peel is typically discarded after processing. Despite knowledge regarding the bioactive substances in the pomegranate peel and peel extracts, including their functionality and diversity, the knowledge is not well known by consumers in general. The aim of this study was to review up to date research trends for processing and developing new functional foods by utilizing nutritional functional substances, favourite food materials, and materials for processing food contained in pomegranate peels and pomegranate peel extracts. This study will summarize the data found in pomegranate peel and pomegranate peel extract literature mainly recently published in Science Direct. There are polyphenolic compounds (ellagitannins, punicalagin, proanthocyanidin, flavonoids, polysaccharides, etc.) in the fruit peel, making up about 50% of the pomegranate's weight. The polyphenol content of a pomegranate fruit peel is 149.91 mg/g, which is about 100 times higher than the juice. Paying attention to the fact that the ellagitannin content (14.22 mg/g) in the fruit peel is also twice as high as that of the fruit juice and seeds, that confirms the possibility of utilizing the peel as a food ingredient capable of developing new, functional bioactive foods.

  • The relatively new concept of functional foods is supportive of sales of food products that deliver isolated 'nutrient' or 'food compound' substances, much as is done by dietary supplements. Whether such isolated substances have benefit must be investigated in each instance; such investigations can be complex. At the same time, simply prepared natural plant foods contain a myriad of substances that, in accord with the concept of food synergy, are beneficial for health. Whole grain foods are an example of such healthy fare, based on strong epidemiologic and experimental evidence. If the concept of functional foods is to be of use for the public health, it should support the consumption of healthy traditional foods as well as promoting 'novel' foods; in this sense, whole grain foods, which have great functionality, should be regarded as functional foods.

  • Gastrodia elata Blume is a achlorophyllous orchid plant that has been used in traditional medicine to treat many human illnesses, such as vertigo, hemiplegia, and epilepsy. It contains three major pharmacological substances; gastrodin, ergothioneine, and vanillyl alcohol. Here we investigated the quantitative changes in those functional components by cultivation conditions and harvest times. The content of ergothioneine was different with cultivation areas, while gastrodin accumulated the higher levels than vanillyl alcohol regardless of cultivation areas. The smaller tubers contained the higher concentrations of gastrodin and the lower concentrations of ergothioneine than did the larger tubers. The cultivation under sun shade screen increased the concentrations of both gastrodin and vanillyl alcohol but decreased the levels of ergothioneine. We also determined the contents of functional substances depending on the harvest times. The concentration of gastrodin was higher in October than in April, while the level of ergothioneine was higher in April than in October. Interestingly, the use of sexually propagated seed tubers produced 1.9 times higher levels of gastrodin compared to vegetatively propagated seed tubers. In this study, we found that three major functional substances in G. elata tubers altered depending on various cultivation practices, which might be important to increase the economic values of G. elata tubers.

  • Foods and related substances from diverse sources known to have a potential for disease risk reduction are called functional foods, while nutraceuticals are bioactive compounds isolated from food and sold in dosage form. Nutraceutical and functional food industries are rapidly growing in recent years and most of the cases development of these functional materials involves certain biotransformation processes. A number of bioactive compounds has been identified up to date and isolated from seafood related products through enzyme-mediated hydrolysis. The enzymatic bioconversion process require suitable biocatalysts and appropriate bioreactor systems to incubate byproducts with digestive enzymes. Membrane bioreactor technology is recently emerging for the development of bioactive compounds from seafood processing byproducts.

  • Silkworm food has been found to be effective for dementia, liver function, lowering blood sugar, and possesses antioxidant properties, which has been attracting attention as a health functional food. In this study, methods for enhancing the functionality of silkworms were explored and the production potential of high-functional silkworms was analyzed. For enhancing antioxidant activity, ascorbic acid, caffeic acid, laminarin, and glutathione were injected or fed to 5th instar silkworms, and the antioxidant activity of silkworm extract was comparatively analyzed. There was no significant change in polyphenol and flavonoid content, but it was confirmed that 2,2-diphenyl-1-picrylhydrazyl radical scavenging ability, superoxide dismutase-like activity, and reducing power were slightly increased after injection of ascorbic acid, caffeic acid, and glutathione. To confirm the increase in antioxidant efficacy through feeding, an inducer was mixed with sucrose and sprayed on mulberry leaves. As a result, the growth rate of silkworms improved and all indicators of antioxidant activity were improved in silkworms fed with ascorbic acid and glutathione. Considering these results, producing high-functional silkworms was deemed possible.

  • 본 연구는 유럽과 오세아니아의 선진국형 기능성 축산물 및 식육제품의 운영현황 및 관리방안을 연구 분석함으로서 국내 실정에 부합되는 규격기준 표준화와 관리방안 및 제도를 마련하는데 있어서 기초 자료를 제시하는데 있다. 우리나라를 비롯하여 전 세계적으로 국제경쟁력 강화 차원 등의 여러 여건 변화로 식품의 3차적 기능이 점차 강조되고 있다. 따라서 우리나라 자체적으로 기능성 축산물에 대한 정확한 정의와 범위를 확립하는 것이 시급하다. 식품에 기능성 표시를 허용하는 것은 이미 국제적인 대세이다. 유럽과 오세아니아에서도 별도의 기능성 축산물에 관한 법률이나 관리제도가 없으나 식품의 기능성 강화 측면에서 영양표시기준(nutrition claims)과 건강표시기준(health claims)을 통해 식품을 관리하고 있다. 강화 영양소에 대한 표시기준은 일부에 국한되어 있어 이들 기준을 사용하여 국내의 기능성 축산물 및 식육가공품에 적용할 경우, 기능성 지표물질 및 허용량의 설정이 반드시 이루어져야 할 것으로 보이며, EU와 호주 뉴질랜드에서 운영하는 제도 이외의 다른 선진국의 사례를 바탕으로 기능성 축산물에 대한 표준화가 이루어져야 할 것으로 보인다. 또한 기능성 축산물 및 식육제품의 표시를 확립하기 위해서는 현재 시중에 유통되고 있는 제품에 사용되는 기능성 소재 조사 및 각 기능성 소재가 인체에 유해한지 안전성에 대한 연구가 필요하며, 이들 소재의 적정 사용범위 설정을 위한 data base를 확립하기 위해 많은 실험적인 연구가 요구된다.

  • 매립지 침출수에 의한 지하수의 오염으로 생성되는 대수층내 오염대 내에서 휴믹물질이 다른 오염물질의 이동 및 변환에 미치는 영향을 평가하기 위한 기초연구로서 매립지의 매립년한에 따른 침출수중에 존재하는 휴믹물질을 추출하여 그 특성을 분석하였다. 추출된 휴믹물질에 대해 원소분석을 실시하였으며, 분광학적 분석으로서 자외선-가시광선, 적외선, 형광 분광분석과 $^1H$$^{13}C$ 핵자기공명 분석을 실시하였다. 침출수중에 존재하는 휴믹물질은 토양 및 수중으로 부터 추출된 휴믹물질에 비해 구조적으로는 지방족 화합물에 의한 특성이 방향족 화합물에 의한 특성에 비교하여 우세하였으며, 이로부터 침출수 휴믹물질의 휴믹화 정도가 상대적으로 낮음을 알 수 있었다. 한편 매립지의 매립년한이 증가할수록 침출수 휴믹물질의 휴믹화 정도는 증가하는 특성을 보였다.

  • Many plants and animal have long been known to have medicinal effects and therefore have been used as medicines. There are many substances that show various pharmacologic efficacy such as anti-tumor efficacy, anti-inflammatory efficacy, cholesterol-lowering efficacy, anti-coagulant of blood efficacy and anti-bacterial efficacy. I summarized the recent advances in research on physiologically functional foods. The pharmacological efficacy of dietary fiber, chitin & chitosan, DHA(docosahexaenoic acid), mushroom, alginic acid and herbs have selected as topices for discussion. I was examining the anti-coagulant activity of herbs, I discovered that Eugenia caryophyllata T. (clove) had a relatively high anti-coagulant activity.
