  • China is the largest rice producer in the world, with about 28 million hectares rice-planting area. Most of the rice is consumed domestically as daily staple food, with a small proportion consumed as feed and deep-processed products. The low elastic elasticity and low profit of rice production which hampers the development of the industry, is due to the low quality of rice grain, low processing level and undeveloped rice processing technique. Promotion of high-quality species, effective quality control, adoption of modem Processing techniques, My use of low-quality indica rice, and utilization of specialty rice are considered as priorities in rice industry.

  • Aspergillus luchuensis 34-1 was inoculated into wheat pellets with different conditions of raw materials to produce nuruk. The degree of substrate reactivity improvement of steam treated raw materials compared with that of non-heat treated was analyzed. The water content of the pellet was adjusted to 25% and 35%, and steam treatment for 10 minutes improved the substrate reactivity at 2.1-fold and 3.1-fold, and sterilization was also possible. The characteristics of improvement pellet nuruk were investigated according to the degree of crushing and water content of raw materials according to the temperatures and humidities ($23^{\circ}C$, $30^{\circ}C$ and RH 60%, RH 80%). The pH of the pellet nuruk was higher depending on the temperature, humidity and moisture content of the koji were lower, and the pH of the flour-pellet nuruk was lower than that of 2 mm milling wheat-pellet nuruk according to milling degree. It can be seen that the milling degree affects the growth of mold. The acidity and amino acid were generally higher as fermentation time increased. Also, the higher the incubation temperature, humidity and moisture content, the higher the value. Glucoamylase activity was significantly the highest in moisture content 35% D2b nuruk, cultured at $30^{\circ}C$ and 80% RH for 38 hours. This is higher than the previous reports on glucoamylase of rice-koji or commercial nuruk using fungi isolated from traditional nuruk. From these study, it is expected that making of improvement pellet nuruk would save the fermentation time considerably compared with traditional nuruks.

  • 양잠농가의 소득증대 및 산업기반 확대를 위한 새로운 형태의 고 부가가치 양잠산물 창출을 통하여 현재까지 섭취가 어려웠던 5령4일부터 숙잠기 누에의 식용화를 위한 가공기술을 개발하였다. 농민들도 쉽게 가공이 가능하도록 생누에를 열수에 침지하여 삶거나 수증기로 쪄서 익혀 본 결과 누에의 몸체와 더불어 누에체내에 들어 있는 견사선의 섭취가 가능함은 물론 맛도 좋은 것으로 나타났다. 상기 기술은 원천기술로서 향후 일반식품, 건강기능식품, 화장품, 애완동물용 사료 등으로의 광범위한 활용이 예상돼, 양잠농가 소득증대와 산업기반 확대에 큰 기여를 할 것으로 기대된다.

  • Since 1985, the growth rate of population of the world is over that of the food production. The cultivated land and the grain production rate are decreasing every year. Therefore, the most serious crisis which we will meet in the 21st century will be food shortage. In order to solve this desperate shortage of food, besides trying to produce more food, the technology of post-harvest, food processing, and food packaging should be developed to reduce and make the best use of the amount of the already produced agricultural products for which a lots of cost and labors were invested, but are being wasted during food distribution channel due to their undeveloped technology.

  • Clostridium perfringens strains were isolated from swine diarrhea in Korea. Three out of nineteen (15.8%) isolates of C. perfringens were found to be enterotoxigenic by PCR analysis. PCR-based genotyping of the three enterotoxigenic isolates of C. perfringens revealed that they were types A, C and D, respectively. These results suggest that various types of enterotoxigenic C. perfringens can cause swine diarrhea, and that the presence of enterotoxigenic type A strain, known to be strongly associated with food poisoning, may cause public health problem in Korea.

  • When baking, the proper blending or mixing of materials will affect the quality of the product. The mixing strength is important when establishing the optimal conditions for batter, and control of the mixing condition is accordingly an important factor. This study investigated the effects of the mixing speed and time on the quality characteristics of a gluten-free type of rice batter. The batter samples manufactured for this purpose are as follows: control (+) (wheat flour), control (-) (rice flour), T1 (1,800 rpm, 1 min), T2 (1,800 rpm, 2 min), T3 (1,800 rpm, 3 min), T4 (3,600 rpm, 1 min), T5 (3,600 rpm, 2 min), T6 (3,600 rpm, 3 min). In this study, rice flour was used in the T1 to T6 samples. The pH of the batter tended to be higher when the mixing speed was slower and the time was shorter depending on the ultra-high mixing conditions. The moisture content of T3 was highest, and there was no difference according to the ultra-high speed conditions. The specific volumes of the ultra-high mixing treatments were higher than those of the control samples. The relationship between the specific volume, hardness and springiness of rice bread according to the mixing speed and time was weak. Therefore, it is considered that the application of ultra-high speeds when manufacturing gluten-free batter can have a positive effect on improving the production efficiency by reducing the processing time.

  • 본 논문은 황기재배 농가의 미생물학적 위해요소를 분석하였다. 충북 제천소재의 4곳의 농가를 선정하여 수확 후 처리 설비 (세척기, 세척수, 손수레, 선별 작업대, 건조선반, 결속기), 작업자의 손 및 수확 후 처리 단계별 황기(세척 전, 세척 후, 선별 후, 건조 후)로부터 샘플을 채취하여 위생지표세균과 병원성 미생물에 대한 오염도를 조사하였다. 수확 후 처리 설비의 총 호기성 세균과 대장균 군은 각각 0.93~4.86, 0.33~2.28 log CFU/$100cm^2$, mL의 수준으로 검출되었으며, 작업자의 손에 대한 미생물의 오염도는 5.43~6.11, 2.52~4.12 log CFU/Hand로 수확 후 처리설비보다 높게 검출되었다. 병원성 미생물에 대한 연구결과, B. cereus가 수확 후 처리 설비, 작업자의 손, 황기에서 각각 0.33~2.41 log CFU/$100cm^2$, mL, 1.48~3.27 log CFU/Hand, 0.67~3.65 log CFU/g으로 측정되었다. 정량분석에서는 S. aureus가 측정되지 않았지만, 정성분석에 의해 세척기, 작업대, 작업자의 손, 황기 (세척 전, 선별 후)에서 검출되었다. 본 연구에서 황기의 수확 후 처리 설비와 황기에서의 미생물학적 오염도를 측정한 결과, 개인 위생 및 작업시설의 위생상태를 청결하게 유지하여 교차오염을 방지해야 할 필요가 있는 것으로 판단된다.

  • This study explored how temperature, time, and moisture content affect the rheological properties (apparent viscosity, flow behavior index, and consistency coefficient) of stored tomato and pepper purees. These purees were prepared with moisture contents of 85%, 90%, and 95% (w/v) using the hot-break method and tested over 6 days at 2-day intervals and temperatures of 5℃, 10℃, and 15℃. Results displayed distinct ranges for apparent viscosity, consistency coefficient, and flow behavior indices: tomato puree (2,519.9-4,324.6 mPa·s, 258.0-550.6 mPa·Sn, 1.80-0.48) and pepper puree (2,105.6-4,562.0 mPa·s, 268.4-580.4 mPa·Sn, 0.22-0.48). The temperature and storage time had significant (p≤0.05) effects, but moisture content did not affect these properties. Flow behavior and consistency coefficients demonstrated relative variation with apparent viscosity, indicating pseudoplastic behavior. Optimal processing and storage conditions were identified within specific ranges: 13.21-14.42℃ for 2 days with 92.22-94.23% (w/v) moisture content for pepper, and 8.42-11.77℃ for 2-6 days with 85% (w/v) moisture for tomato.
