The purposes of this work were to investigate the changes in GABA content of six different rice cultivars along with viatmin E content and antioxidant activity after germination. Brown rice was soaked for 24 hr at 25℃ and then germinated at 37℃ for 48 hr. The content of GABA and vitamin E in the rice samples was measured by using spectrophotometeric and HPLC methods, respectively. Antioxidant activity was measured by ABTS (2,2`-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging methods. GABA and vitamin E contents were significantly increased after germination while no significant change in the antioxidant activity was observed. Among the samples tested, Geunnun cultivar contained the highest GABA content before and after germination. On the other hand, Sinmyungheugchal cultivar showed the highest content of vitamin E and antioxidant activity compared to other rice cultivars. In conclusion, the germinated rice with high GABA content can be used for a functional ingredient in rice processing industry.

Tests were conducted to obtain heat transfer coefficients during slush formation from 10% sucrose solution. The slush was made by scraping the ice formed on the cylinder. Cold brine was supplied inside of the evaporator cylinder to cool the outer surface. Below a certain brine temperature, which was -5 ℃ in this study, the solution was supercooled, and suddenly turned into ice crystals. During slush formation, the heat transfer coefficient oscillated significantly, due to periodic removal of ice chunk form the surface. The average heat transfer coefficient during slush formation was 40~70% higher than that obtained during single phase cooling. The heat transfer coefficient was also affected by the brine temperature with increasing heat transfer coefficient at higher brine temperature.

This study was conducted to analyze the nutrient compositions of stem and fruit of Opuntia ficus-indica var. saboten (OF) and Opuntia humifusa (OH). The results of the two-way analysis of variance test indicated that the parts, varieties and parts*varieties had influence on nutrient content except crude protein, soluble dietary fiber, Fe, Se, I, vitamin E, niacin and vitamin C. Moisture and crude ash content was higher in stem than in fruit, while crude lipid and insoluble dietary content was higher in fruit than in stem. Mineral content revealed that K (1,313.67 mg% in OF, 1,351.38 mg% in OH) was the highest in fruit and Ca (5,146.29 mg% in OF, 1,388.19 mg% in OH) was the highest in stem. Vitamin C was the most abundant vitamin in the fruit of OF (199.98 mg%) and OH (187.12 mg%). Polyunsaturated fatty acid was the highest among fatty acids (66.9~70.1%), with higher content in the stem (753.89 mg%) than fruit (578.01 mg%) in OF, while higher in the fruit (1,093.63 mg%) than stem (475.07 mg%) in OH. Moisture, crude protein, Mg, Se and riboflavin was higher in OF than OH; whereas, crude lipid, insoluble dietary fiber, total dietary fiber and monounsaturated fatty acid were higher in OH than OF. These results indicated that OF and OH could be a good food source for Ca, K and Vitamin C. Also, different nutrient content by parts and varieties, can be helpful in choice of parts or varieties for consumer purposes.

본 연구에서는 컨베이어식 원적외선 건조기를 이용하여 송풍속도와 건조온도에 따른 표고버섯의 건조특성과 건조제품의 색도변화를 조사하고 건조조건에 따른 표고버섯의 항산화성분과 항산화력의 변화를 분석함으로써 고품질의 원적외선 건조 표고버섯 제품 생산을 위한 기초 자료를 제시하고자 하였다. 컨베이어식 원적외선 건조의 경우 건조실 온도가 높고, 풍속이 증가할수록 건조속도가 빠른 것으로 나타났으며 열풍건조에 배해 건조시간을 약 $3\sim6.5$시간 단축할 수 있는 것으로 나타났다. 원적외선 건조에 의한 표고버섯의 항산화성분과 항산화력의 감소율은 $60^{\circ}C-0.6\;m/s,\;60^{\circ}C-0.8\;m/s,\;70^{\circ}C-0.6\;m/s$ 조건일 경우에만 열풍건조에 건조에 비해 적은 것으로 나타났으며, 그 이상의 조건에서는 열풍건조보다 손실률이 큰 것으로 나타났다. 따라서 원적외선 건조 내부의 건조조건을 저온 저속으로 결정한다면 표고버섯의 항산화성분과 항산화력의 손실을 최소화하고 열풍건조기에 비해 신속하고 색도의 변화가 최소화된 고품질의 표고버섯 제품을 생산할 수 있을 것으로 생각된다. In an attempt to find ways of improving the quality of dried Shiitake mushroom, this study compared a conveyer-type far-infrared drying method with a traditional heated air drying method. The conveyer-type far-infrared dryer was performed at air velocity of 0.6 and 0.8 m/s under drying air temperature of 60, 70 and $80^{\circ}C$, respectively. Drying characteristics, antioxidant activities and the antioxidant compounds of Shiitake mushroom dried by far-infrared dryer were investigated. Generally, drying rate with the conveyer-type far-infrared drying method was faster than that with the traditional heated air drying method. In the conveyer type far infrared drying method, drying rates were increased with increasing temperature and air velocity. The loss of antioxidant activities during the conveyer-type far-infrared drying method at 60-0.6, 60-0.8, and $70^{\circ}C-0.6m/s$ was less than the traditional drying method. However, the loss of antioxidant activities at 70-0.8, 80-0.6, and $80^{\circ}C-0.8m/s$ was higher than that of the traditional drying method. Therefore, the conveyer type far infrared drying conditions with below $70^{\circ}C$ and 0.6 m/s air velocity may produce dried Shiitake mushroom with relatively higher antioxidant activities and antioxidant compounds.
