본 시험은 직파시기가 총체 벼의 수량 및 사료에 미치는 영향을 구명하기 위하여 2005년부 터 2006년까지 축산과학원 초지사료연구센터 시험포장에서 수행되었다. 총체 벼 품종은 남일벼로 하였고 4월 25일부터 6월 4일까지 15일 간격으로 직파하였고 5월 25일 이앙구를 대조구로 하였다. 출수기는 파종기가 늦어짐에 따라 지연되었으며 조단백질 함량은 증가되었다. ADF 및 NDF 함량은 파종이 늦어짐에 따라 증가되었으며 평균 TDN 함량은 61.5%이었고

활성 글루텐 첨가가 쌀베이글의 품질 특성에 미치는 영향을 조사하였다. 쌀가루에 글루텐 첨가량이 증가함에 따라 보수력은 증가한 반면, 알칼리수 흡수율은 감소하였다. Pelshenke값과 침전가는 글루텐의 첨가량이 증가함에 따라서 유의적으로 증가는 하였으나 강력분의 Pelshenke값과 침전가에는 미치지 못하였다. 최고점도와 setback 및 peak height와 peak width는 글루텐의 첨가량이 증가함에 따라서 감소하는 경향을 보였다. 글루텐을 23% 첨가할 경우 베이글의 부피는 글루텐 11% 첨가 후와 비교할 때 2배 이상 증가하였으며 글루텐의 첨가량이 증가할수록 베이글의 경도, 검성 및 씹힘성은 감소하는 경향을 나타내었다. 베이글의 비용적과 물 흡수력, Pelshenke값 및 침전가와는 고도의 정의 상관(r =0.962, r =0.964, r =0.966)을 나타내었다.

본 시험은 품종 및 수확시기가 총체 벼 사일리지의 품질에 미치는 영향을 구명하기 위하여 2004년부터 2005년까지 축산연구소에서 수행되었다. 식용벼인 추청벼와 총체 벼 전용품종인 하마사리를 이용하여 생육시기별로 6회(출수기, 개화기, 유숙기, 호숙기, 황숙기 및 완숙기)에 걸쳐 수확을 하여 사일리지로 조제하였다. 조단백질 함량은 숙기가 진행됨에 따라 감소되었으며 TDN 함량은 증가되었다. 평균 조단백질 함량은 총체 벼 전용품종이 식용벼 품종보다는 높게

Quality characteristics of dasik were studied with varied the levels of rice grain particle size and green tea powder and compared them with commercially sold dasik. Among the samples with the same number of grinding times, the sample groups with the higher amount of green tea showed significantly the less mosture content(p<0.05). Hardness was higher in the samples containing higher amount of green tea among the ones with the same grain size (p<0.05). The M13G0.5 was evaluated to have the highest savory aroma with significance (p<0.05), and C1 to have the highest sweetness by sensory analysis. The developed dasik samples with lower rice grain particle size had significantly lower adhesiveness, chewiness, gumminess, and cohesiveness compared to those of commercial sample groups. In sensory tests, the compared groups showed significantly the higher savory aroma and flavor and very lower hardness when compared to those of commercial sample groups. With the results above, dasik with with varied the levels of rice grain particle size and green tea powder were developed with improved qualities compared to those of commercially sold dasik.

Effects of Takju(Korean turbid rice wine) lees on noodle investigated by substituting Takju lees water extract powder for each 2% and 4% wheat flour in sample II and III, respectively. The lightness(L) of uncooked noodles was decreased, whereas that of cooked noodles was increased with increasing amount of extract added. Redness(a) and difference of total color(δE) were significantly increased according to the amount of extract added in uncooked and cooked noodles. Yellowness(b) of the noodles containing 2% Takju lees water extract powder was exhibited lowest values in uncooked and cooked noodles. In cooking property of noodles, turbidity of soup decreased in proportion to amount of extract added, 2% and 4% in sample II and III, respectively whereas the weight and volume of noodles were not significant than those of control. Tension of cooked noodle was highest in sample II and lowest in sample III. Texture profile analysis of cooked noodle showed an significant increase of hardness in addition of Takju lees water extract powder but not significant different in springiness, chewiness, adhesiveness. Cohesiveness was significantly lowest in sample II. The sensory evaluation showed that significant difference between noodles with 2% addition groups and control was not recognized but was recognized 4%. Therefore, based on cooking properties and sensory evaluation, Takiu lees water extract powder up to 4% could be substituted for wheat flour.

본 시험은 사료용 총체 벼의 수확시기 및 품종이 수량 및 사료가치에 미치는 영향을 구명하기 위하여 2003년부터 2005년까지 축산연구소에서 수행되었다. 식용벼인 추청벼와 총체벼 전용품종인 하마사리를 이용하여 생육시기별로 6회(출수, 개화, 유숙, 호숙, 황숙 및 완숙기)에 걸쳐 수확하였다. 조단백질 함량은 수확이 늦어짐에 따라 감소하였으나 TDN 함량은 증가되었다. ADF 함량으로 추정된() 평균 TDN 함량은 60% 내외로 나타났다. ADF 및 ND

The quality characteristics of cookies containing brown rice flour, which has a greater variety of functional components than wheat flour, were studied. The results of the pasting properties shows that the inclusion of brown rice flour to the wheat flour-mixture did not affect the pasting temperature for up to 30% inclusion. The total dietary fiber and total polyphenol content increased and color of the cookies became darker with increasing brown rice flour content. According to the results from TA on texture, the hardness decreased and the crispness increased significantly(p<0.001, p<0.05, respectively) with increasing brown rice flour content. From the acceptance test, the aroma and texture of the cookies with added brown rice flour were significantly(p<0.001) lower than those of the wheat flour cookies. However, the appearance, taste, and overall acceptance of the cookies with added brown rice flour did not differ significantly from those of the wheat flour cookies. According to the results from the sensory evaluation, the savory aroma of the cookie with 30% brown rice flour was significantly strong(p<0.001). The brown rice flavor of the cookies with brown rice flour was significantly stronger(p<0.001) than that of the wheat flour cookie, but there were no significant differences among the cookies with brown rice flour in it. The crispness of the cookies increased significantly(p<0.001) with the inclusion of brown rice flour in the mixture, especially for the mixture with 30% brown rice flour which had the highest value of crispness among the cookies. The graininess and brown color of the cookies increased significantly(p<0.001) with increasing brown rice flour content, especially for the mixture with 30% brown rice flour which had the highest values among the cookies.

In this experiment, I used three samples of oils. The oils that I used were hydrated soybean oil, pure soybean oil and regular soybean oil. The group of rice was fried in the each sample of oil that had not been used for a few seconds. Rice was used after frying at 230-235℃ every four hours terms and total frying hours was 12 hours. The hydrated soybean oils was least affected in rancidity. The other two oils were more affected in rancidity than the hydrated soybean oil. However, the trans fatty acid in hydrated soybean oil was 36.5%. The diameter of the poped rice that was fried in pure soybean oil and regular soybean oil that had been used 12 for hours was reduced while the diameter of the popped rice fried in the hydrated soybean oil was not reduced. Also, the groups of rice fried in the pure and the regular soybean oil that had been used for 12 hours reduced the hardness in rice while the group that fried in the hydrated soybean oil at the 12th hour kept the hardness well. In sensory evaluation, rancidity order was found apparently in the pure soybean oil that had been used for 12 hour and in the regular soybean oil that have been used for eight hours and 12 hours. Only the hydrated soybean oil did not have distinctive rancidity order at all. The degree of the crispiness was reduced in the pure soybean oil and in the regular soybean oil at 12th hour frying. However, the hydrated soybean oil preserved the crispiness well until the end of 12 hours of frying. In overall preference test, the pure and regular soybean oil that had been used for 12 hour were not preferable. In conclusion, I found that the group fried in the hydrated soybean oil was better in every evaluation than the groups fried in the pure soybean oil and in regular soybean oil. The hydrated Soybean oil may be better to be used in food manufacturing if the trans fatty acid in the hydrated soybean oil can be reduced.
