        본 연구는 초미세분쇄기술을 이용하여 옥수수전분의 입자구조파괴가 이루어졌을 때 분자구조적, 물리적 변화가 어떻게 이루어지는지를 구명하고자 하였다. 초미세 분쇄처리 후 옥수수전분의 평균직경은 약 50% 감소가 이루어졌으며 비표면적은 567% 증가하였다. 초미세분쇄처리 전·후의 옥수수전분에 대한 분자량분포를 GPC로 측정한 결과 분쇄 후 저분자량의 Peak II의 면적이 21.0%에서 86.5%로 상승하였다. 손상전분 함량은 각각 9.63%와 83.57%로 초미세분쇄처리에 의하여 크게 증가하였다. 옥수수전분의 경우는 겔(gel)을 형성하였으나 초미세분쇄처리 후에는 전분의 분쇄과정에서 전분입자파괴와 아울러 옥수수전분의 분자량이 저분자화 되면서 겔 형성능력이 크게 저하되었다.

        We investigated the consumption inclinations of consumers for environmentally-friendly agricultural products (EFAP) for better production and distribution of EFAP. Consumer inclinations in large supermarkets from April 7th to 30th, 2008 were surveyed. Data were analyzed using the SPSSWIN 12.0 program. Results showed that 90.4% of consumers recognized EFAP and 76.4% of those who recognized the products had actually bought the products. Members of the "have purchased group" bought EFAP once a week because they believed these products were safe from hazards, such as pesticide. The amount spent on EFAP was less than 20% of the total food budget and the major consumed items were green vegetables and fruits. The sale location was mainly large supermarkets and agricultural cooperation outlets. Although many people were satisfied with EFAP from the viewpoint of nutritional and sensory qualities and safety compared with general agricultural products, they were notsatisfied with the price. Many consumers trusted that EFAP were safe and nutritional. Members of the "not purchased group" also trusted the nutritional and sensory qualities of EFAP and recognized the safety issue, but they were not satisfied with the price, compared with general agricultural products. Consequently, to succeed in the market, EFAP should maintain the confidence of the consumer while decreasing in price.
