  • The physical condition of rapeseed delivered to fat industry plants plays a significant role in the formation of the qualitative features of the raw material for oil production and, consequently , of the oil itself. Rapeseed is stored in silos , frequently for months, before it is subjected to processing. During the long storage, the conditions of the seed cover is very important, as the seed cover provides natural protection of the seed against the effect of the environment. Seeds with damaged seed cover are more easily affected by mildew, and the rate of chemical processes. Deteriorating the quality of oil contained in the cotyledons is faster in such seeds. Cracked seed covers facilitates also the growth and development of microorgaism. So as rapeseed damage occurring inthe course of harvest and the post-harvest processing have a negative effect of the quality and quantity of oil the sees contain. The study presented here was aimed at examining the typical process of purcha ing and handling of rapeseed in fat industry plants, in the aspect of the occurrence of mechanical damage to the seeds. Special attention was paid to the condition of rapeseed immediately after combine harvesting : next , the successive stages of technological handling of the seed were examined. observing the operation parameters of the particular machinery and equipment in order to identify those operations which caused deterioration in the quality of the material (sees). Seed samples were taken successively from the following the hopper, prior to cleaning , after cleaning , prior to drying , after drying, from dry rape silo. The total level of damage increased through the handling. The content of unusable contaminants had the tendency to decrease in the successive operations. though the actual values still exceeded levels permitted by standards. The study allow to indicate the operation fo postharvest technological process, which cause the most seed damage as well as gave quantita ive description of the losses occurred.

  • Apple ring rot disease, caused by Botryosphaeria dothidea (Moug. ex. Fr) Ces. et de Not., is one of the most important diseases on apple fruits. In this study, strain 9001 isolated from healthy apple fruits from an infested orchard was evaluated for its biocontrol activity against apple ring rot in vitro and in vivo. Strain 9001 showed obvious antagonistic activity to B. dothidea YL-1 when plated on potato dextrose agar. Soaking healthy apples in the bacterial suspensions of strain 9001 prior to artificial inoculation of fungal pathogen resulted in a dramatic decrease in disease incidence when compared to the control. Moreover, either field application in the growth season or postharvest treatment of apples from infected orchards with bacterial suspensions of strain 9001 resulted in significantly reduced disease incidence within the storage period for 4 months at room temperature. Based on the phylogenetic analysis of 16S rRNA and the gyrA gene, strain 9001 was identified as Bacillus amyloliquefaciens. These results indicated that B. amyloliquefaciens 9001 could be a promising agent in biocontrol of apple ring rot on fruit, which might help to minimize the yield loss of apple fruit during the long postharvest period.

  • In recent years, Korean rice must compete with the rice of advanced countries under Doha Development Agenda(DDA) and free Trade Agreement(FTA). Therefore we should find more active and positive solution in rice industry according to the inncreasing power of international pressure. Increasing rice production was the most important policy during the past food-deficient days, but recently, with overproduction of rice, various circulation system by the brand(price)-differentiation should be settled in a recent market of Korea. Nowadays, some advanced rice farmers and Rice Processing Complex(RPC) managers developed new brands of rice with high-quality, adding healthy materials and environment-friendly farming methods. Therefore, the future strategy of making a new brand rice should be planned including selection of rice variety, cultural and post-harvest techniques, circulation and processing methods to compete against foreign rice. And environment-friendly farming is also recommendable for food safety and differentiate from imported rice. For the purpose of successful brand-rice, the following points might be considered. Firstly, selection of good quality rice and continual development of good variety must be conducted for the differentiation of Korean rice from foreign rice. Secondly, a special contract between producer and consumer with functional-rice, organic filming-rice, specific-rice will be recommendable. Thirdly, improvement of post-harvest management and milling system are necessary for the production of differentiated-rice. Fortunately, standard of inspection, rules of description for brand-rice must be developed by a more scientific examination in order to settlement of trust for consumer. Finally, provincial or regional-representative brand rice must be settled and conducted for the development of agreement market system between producer and consumer.

  • 본 연구에서는 동양배 '진황'의 1-MCP처리 후 유통온도에 따른 과실의 품질 변화를 관찰하였다. 과실의 감모율의 경우 저장온도가 낮을수록 적었으며 1-MCP처리구가 무처리구 보다 유의하게 적은 감모를 보였다. 수확 후 1-MCP처리는 과육경도에서 유통온도(18, 25 및 $30^{\circ}C$)와 관계없이 20N이상으로 무처리구보다 높게 유지되었다. 과피색의 변화는 모든 처리구에서 저장기간이 길어질수록 어두워졌으며, $a^*$값은 18 및 $25^{\circ}C$에서는 처리구간 차이를 보이지 않았지만, $30^{\circ}C$에서는 1-MCP처리구가 유의하게 적은 변화를 보였다. 과실의 생리장해에서 과심갈변, 분질과 발생은 저장온도가 낮을수록 발생이 적었으며, 1-MCP 처리구가 무처리구 보다 낮은 발생을 보였다. '진황'과실에서 1-MCP처리후 유통온도에 따른 과실의 품위유지 기간은 18 및 $25^{\circ}C$에서는 28일 내외이며, $30^{\circ}C$에서는 21일 내외로 1-MCP 처리로 유통기간을 약 7일 이상의 품위유지에 효과를 보였다. 이러한 결과는 특히 고온의 시장조건에서는 조생종 '진황' 과실에 1-MCP처리가 품위유지에 효과적인 것으로 사료된다.

  • 본 연구는 오리엔탈 나리 절화 'Siberia'의 잎 황화에 대한 수송온도와 전처리의 효과를 알아보고자 수행하였다. 나리절화는 5, 10, 15, $25^{\circ}C$에서 5일 동안 수송하였다. $25^{\circ}C$로 수송 시 잎 황화가 심하게 일어났지만 $5^{\circ}C$에서 $15^{\circ}C$로 수송시에는 잎 황화가 크게 감소하였다. Promalin(BA + $GA_{4+7}$) 전처리는 무처리와 비교해 잎 황화를 크게 감소시켰다. Promalin 처리는 수확 후 잎 황화를 완벽하게 예방하였지만 $GA_3$와 Chrysal SVB 처리는 효과적이지 못했다. 잎 황화는 Promalin 분무처리보다 침지처리 시 더 감소되었다. 그리고 Promalin 처리는 나리의 절화 수명을 연장하였다. Promalin 전처리 시 엽록소 형광반응의 최대광량자수율값이 높게 유지되었으며, 특히 엽록소 함량이 크게 증가하였다. 따라서 나리절화 'Siberia'는 $5^{\circ}C$에서 $15^{\circ}C$로 수송하였을 때와 Promalin 침지 전처리 시 잎 황화를 크게 경감하였다.
