2004년 쌀 시장개방을 대비하고 갈수록 높은 소비자의 구미요구에 맞은 고품질 쌀을 생산하기 위하여 특수미 및 영양미의 생산이 시급하다. 더 나아가 우리 농가의 생산소득을 높이기 위해서 경쟁력이 강한 고품질의 농산물이 반드시 개발되어야 한다. 최근에 국내에서 여러 가지 특수미가 유통 및 판매되고 있다. 예를 들자면, 배아미, 발아현미, 무세척미, 기능성 쌀 등을 들 수 있겠다. (중략)

The objective of this study was to determine antioxidant compounds in specialty rice including milled rice, brown rice, red rice, giant embryonic rice, black rice, green rice, and Goami consumed in Korea. The concentrations of total polyphenols (insoluble and soluble polyphenols), phytic acid, and anthocyanin in the samples were measured using spectrophotometric methods and vitamin I analysis was carried out by HPLC. The contents of the total polyphenolic compounds were 565mg/100g for black rice, 405mg/100g for red rice, 140mg/100g for giant embryo rice, 138mg/100g for Goami, 133mg/100g for brown rice, 127mg/100g for green rice, and 66mg/100g for white rice. The black and red rices were significantly high in polyphenolic contents compared with the other rices, apparently due to their intense red-purple color. Black rice, red rice, and Goami showed significantly higher vitamin E and phytic acid contents compared with other rices. Anthocyanins were determined in only black rice (302mg/100g) due to the detection limits of spectrophotometric assay. hlthough vitamin I and anthocyanin contents were relatively lower than polyphenolics among the samples, the specialty rice may contribute to the significant supply of antioxidant compounds to prevent oxidative stress due to the fact that rice is used as a staple food and consumed in large amounts in our diets. The results can be used to increase rice consumption by enhancing consumer awareness on health benefits of the rice.

최근 농산물 시장의 개방에 따라 외국의 값싼 농산물이 지금 우리 유통시장에서 점차적으로 많이 판매되고 있다. 우리 농가의 생산소득을 높이기 위해서 경쟁력이 높은 고품질의 농산물이 생산되어야만 한다. 특히, 지금 우리나라 쌀 시장이 2004년에는 완전 개방되므로 이에 대비해서 쌀의 고품질화 및 특수미 개발로 우리 쌀의 국내소비량 및 국제 경쟁력을 높여야 한다 최근에 국내에서 여러 가지 특수미가 유통 및 판매되고 있는데 예를 들면, 배아미, 영양강화미, 발아현미, 무세미, 기능성 쌀 등을 들 수 있다. (중략)

The compositions of fatty acid and amino acid of specialty rice which includes colored rice (Heugjinju, Jeugjinju, Josangheugchalbyeo), flavored rice (Heughyangmi, Hyangmi1), and giant embryo rice (Keunnun) were determined and compared to those of regular rice (Ilpumbyeo, Whaseonchalbyeo). Major fatty acids were linoleic acid (C18:2) and oleic acid (C18:1), which were composed of 75~80% of total fatty acids. Major amino acids were glutamic acid and aspartic acid in most cultivars but Jeugjinju in which cysteine (169.61 nmol) and GABA (129.32 nmol) were the most abundant amino acids. Thermal properties measured by differential scanning calorimeter (DSC) revealed that the enthalpy (${\Delta}H$) for starch gelatinization was the highest in Josangheugchalbyeo and Whaseonchalbyeo. It suggests that the starch structure of waxy rice could be more crystallized compared to non-waxy rice, and also that amylopectin could have more impact on starch gelatinization than amylose. The on-set and complete temperature for starch gelatinization were higher in colored rice of Heugjinju and Jeugjinju, and regular rice of Whateonchalbyeo.

The objectives of this study were to determine antioxidant activity of the methanolic extracts from some specialty rices and to investigate relationships between antioxidant activities and antioxidant contents in the extracts. ABTS (2,2-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) radical cation scavenging activity, inhibitory effect on lipid peroxidation, chelating activity, reducing power and inhibitory effect on xanthine oxidase have been used to investigate the relative antioxidant activity of the extracts from specialty rices. The concentrations of total polyphenolics, phytic acid, and anthocyanin in the extracts were measured by spectrophotometric methods and vitamin E analysis was carried out by HPLC. The methanolic extracts prepared from black and red rices showed higher antioxidant activities and contained higher antioxidant compounds compared with other rices, apparently due to their intense red-purple color. The correlation coefficient between total polyphenolic content of methanolic extracts and ABTS radical cation scavenging activity, reducing power, and inhibitory effect of xanthine oxidase were 0.9921, 0.9856, and 0.8032, respectively.

최근 중국 WTO가입과 농산물의 시장의 개방에 따라 국내에서 경쟁력이 높은 고품질의 농산물을 생산하려고 있다. 특히 쌀 시장도 2004년에는 완전 개방되므로 이에 대비해서 쌀의 고품질화 및 특수미 개발로 우리 쌀의 국제적 경쟁력을 높여야 한다. 현재 일본 등의 선진국에서는 영양강화미, 발아현미, 향미, 기능성 쌀 등 다양한 특수 미를 생산하고 있다. 국내에서도 인삼 쌀, 잡곡성형 쌀, 혼합곡, 버섯 쌀, 무세미 등을 비롯한 특수 미를 생산하여 판매하고 있으나, 고가, 낮은 저장성, 떨어지는 밥맛, 인공적인 처리로 인한 거부감 등 때문에 일반인에게 기호도가 매우 낮은 편이다.

과거에는 생각지 못했던 치료방법이 속속 등장하고 환자들이 좀더 양질의 치료를 요구함에 따라 의과에서뿐만 아니라 치과에서도 다양한 특수클리닉이 개설돼 있다. 치과에서의 특수클리닉은 구취 클리닉, 임프란트 클리닉, 장애자 클리닉, 레이저 클리닉, 구순구개열클리닉 등이 있으며 이러한 특수클리닉은 의료의 질 향상과 환자의 편의를 도모하면서 점차 확대양상을 보이고 있다. 11개 치대병원을 중심으로 하여 특수클리닉의 현황과 장단점, 앞으로의 전망에 대해 살펴본다.
