Fusarin C, which had been produced in cereals by Fusarium moniliforme, was known as a mutagen. In this study, natural occurrences of fusarin C in 12 kinds of cereals grown in Korea, fusarin C production by F. moniliforme in cereal cultures, and the relation between fusarin C production and water activity were investigated. The results were obtained as follows; 1. Fusarin C was detected large amounts in rice, glutinous millet, sorghum millet, and corn obtained from Seoul markets randomly. But in cereals selected from Pyungtaik market, fusarin C was detected in barley and job's tears only. The amounts were much lower than those from Seoul markets. It was thought that keeping conditions of cereals during retailing period were very important factors to natural occurrences of fusarin C. 2. The amounts of fusarin C production were determined much more in rice and barley cultures with F. moniliforme. In this study, the facts are made clear that rice and barley had been more proper than corn to produce fusarin C by F. monilifome. 3. Water activity had more effect on fusarin C production in corn cultures than rice cultures. In corn cultures, water activity was higher, and the amounts of fusarin C production was larger. In case of high activity (Aw 0.85), the amounts of fusarin C was shown the largest in 1 week after then was decreased rapidly.

사료의 생산비를 절감하여 국제경쟁력을 높이고 결과적으로 축산물의 국제경쟁력을 높이는 것이 모든 정책 결정에 우선적으로 고려되어야 한다. 이를 위하여 행정 및 제도적으로는 사료용원료수입품목의 자유화, 곡류의 수입쿼터제 철폐, 국산곡류의 사료화지양, 사료원료 및 사료에 대한 세제 개선, 사료관리법개선 등의 조치가 취해져야 될 것인데 이러한 문제점들이 개선된다면 20-30$\%$의 사료의 가격경쟁력이 향상되리라고 기대된다. 사료공장의 입장에서 고려해야 할 과제들은 기술의 개선, Computer의 적극응용, 생산시설의 자동화, 생산품의 전문화, 유통질서의 확립 등을 들 수 있는데 이러한 과제들을 발전적으로 해결하므로써 생산비의 절감을 통한 국제경쟁력을 더욱 제고시킬 수 있을 것이다.

A curd yogurt was prepared from milk added with skim milk powder or four kinds of cereal. The effect of cereals at 2%(w/v) level on the pattern of volatile aroma compounds in curd yogurt was investigated. Acetaldehyde, acetone, ethanol, diacetyl, butanol and acetoin in curd yogurt were detected by gas chromatographic analysis. Among these compounds, acetaldehyde, ethanol, diacetyl and acetoin were produced during fermentation by Lactobacillus acidophilus (KCTC 2182). The addition of cereals did not affect markedly general pattern of volatile aroma compounds in curd yogurt. The amount of acetoin and ethanol markedly increased until the first 6 hours of fermentation, and then increased mildly until 24 hours. The amount of diacetyl markedly increased until the first 6 hours and then decreased slightly. Acetaldehyde was first detected by gas chromatograph after 18 hours of fermentation.
