Paddy rice cultivation in Korea has steadily grown-up since 1960 due to improvement of agronomy, Rice production exceed self-sufficency from 1986, resulting 1.5 million tons of surplus rice. Our government has fostered the production of rice-based products which is banned by law until 1986. In order to activate the production of rice-based products, government has provide not only aged rice in cheap price, but also financial support for modernizing production facilities. As a part of their effort Rice Utilization Research Center was expecially established at the Korea Food Research Institute in 1991 to develop varieties of rice-based products. Owing to government effort, 0.3 million tons of rice was used for production of rice-based products at the end of 1993 which is about 5% of total rice production in Korea. However, the amount of aged rice in Korea seems to be used-up by end of 1995. After agreement of UR. 50 thousand tons of rice should be imported from foreign country, causing changes of rice price in the market. Rice is recognized as not only staple food but also major sources of income for agricultural farmers in Korea. Therefore, special plans should be contrived to prevent the decrease of rice comsumption as well as to promote continous rice production. As a part of device, the taste of cooked rice should be improved, new types of products developed for the younger generation, modernizing technics for production of traditional foods are required for increase of rice comsumption. Development of automatic rice cooking system for group diet and research for evaluating nutritional superiority of rice seems to be required. Development of these technics will be helpful to keep up with the foundation of rice processing industry in Korea.
[제2주제]쌀관련 식품의 생리활성 기능과 산업화의 과제

주식으로 먹고 있는 쌀은 당질 급원으로만 인식되었으나 근년 쌀의 생리적 기능에 관한 연구가 활발히 진행되고 있다. 미강과 백미, 현미를 섭취함에 따라 콜레스테롤 저하 효과가 있음을 알 수 있었으며 특히 쌀단백질은 혈중 콜레스테롤의 상승을 억제하고 간장중의 콜레스테롤 축적을 억제하는 효과가 확인되었다. 또한 쌀은 다른 곡류에 비하여 식후 혈당반응이 낮기 때문에 장기간 섭취시 당뇨쥐에서 당대사와 지질대사를 개선하는 것으로 나타나 혈당조절기능이 있음을 시사하고 있다. 특히 미강 및 탈지미강단백질을 pepsin으로 가수분해하여 column chromatography에 의해 분획한(분자량 1.000이하의 small peptide) 획분을 얻어 SHR 쥐에 경구투여하여 jn vivo에서 혈압강하 효과를 조사한 결과 혈압이 저하하는 경향을 확인하였다. 아울러 쌀로부터 분획한 methanol 추출물이 S. typhjmurium reversion assay. SOS chromotest 및 spore rec-assay 등 미생물을 이용한 항변이활성 시험과 동물세포를 이용한 chromosome aberration test에서 억제활성이 측정되었고 억제활성 물질은 질소함유물질 또는 수용성 당류일 가능성은 낮으며 페놀성화합물과 지질이 복합적으로 구성되어 있을 가능성이 높은것으로 사료되었다. 지금까지 밝혀진 결과들은 가능성을 시사한 기초적인 연구이며 향후 이들에 대한 보다 지속적이고 심도있는 연구들이 수행되어야 한다고 본다. Rice, our staple food. was considered only as a source of energy. However, it has been revealed by several studies that rice functions physiologically. Rice bran, milled rice and brown rice showed hypocholesterolemic effect. and rice protein decreased blood and liver cholesterol of rats. Rice has been known to exert lower postprandial blood glucose response compared to other cereals. and long-term rice feeding improved glucose and lipid metabolism of rats. Pepsin hydrolysate from full-fat and defatted rice bran protein showed angiotensin I converting enzyme(ACE) inhibitory activity. Supplementation of ACE inhibitory peptides partially purified by column chromatography lowered blood pressure of spontaneously hypertensive rats. The methanol extract of brown rice showed inhibitory effects on mutagenicity induced by various mutagens in Samonella typhimurium reversion assay. SOS chromotest and spore rec-assay. The extract also had antimutagenic effect in chromosome aberration test using animal cell. The antimutagenic component might be complex of phenolic compound and lipid. The findings mentioned above may be only an example of the function of rice unravelled yet. So more research should be conducted to elucidate the physiological function of rice.
