Quality attributes of fresh waxy corn (Zea mays L.) as affected by pre-cooling and storage temperature (4˚C and room temperature) were investigated in terms of weight loss, moisture, color, reducing sugar content, and sensory quality. Two varieties of waxy corn with white and black kernel color, Ilmichal and Heukjinjuchal respectively, were cultivated at the field of National Institute of Crop Science in 2007 and 2008 to determine the physiologically optimal storage condition for higher eating quality stored in refrigerator of 4˚C and room temperature. They are pre-cooled immediately after harvest with ice for 5 hours. Quality analyses were monitored during 10 days at 4˚C storage room comparing with those of non cooled and stored at room temperature. A higher weight loss over 15% observed in both of two waxy corn varieties that were stored at room temperature. But there was not significantly difference with variety or pre-cooling treatment. There was up to 10% increase in moisture content in kernels non pre-cooled and stored at room temperature. For all treatments, very small amount of free sugar were detected, however, there were no significant differences between treatments. Glucose concentration increased with time in kernels stored at 4˚C and the effect of pre-cooling was not significant. A general darkening in color of kernels and a trend to turn yellow was observed in the pre-cooled corns when they were steam-cooked. Total sensory scores of corns stored in 4˚C were better than those of samples stored in room temperature and there was not significantly difference with variety or pre-cooling treatment. As storage period was longer, shelf lifes of waxy corn in control and waxy corn treated with technique applied to store waxy corn, and the quality of waxy corn could be maintained and the storage expense could be saved during storage. It is required that further studies narrow down the effect of pre-cooling on fresh waxy corn during short time storage.

This study investigated the changes in chemical components, antioxidant compounds, and activity before (BG) and after germinated (AG) brown rice in order to promote the availability of these beneficial factors. The GABA content of BG and AG brown rice were 0.07~6.61 and 11.13~49.72 mg/100 g, respectively. The ${\alpha}$-amylase activity of AG brown rice was 1.77~70.25 unit/g fold higher than it was in BG brown rice. Total polyphenol and flavonoid contents, which are known to be related to antioxidation, were higher in BG brown rice than in AG brown rice. The total polyphenol contents of BG and AG brown rice were 10.52~36.38 and 11.38~26.33 mg/100 g, and the total flavonoid contents were 3.55~13.39 and 3.52~9.78 mg/100 g, respectively. Also, DPPH radical scavenging activity was 57.64~251.34 and 50.49~213.35 mg TE/100 g, respectively. ABTS radical scavenging activity and total tannin content showed a similar trend to DPPH radical scavenging activity. We expect that this data will be useful in the manufacturing of food products. 본 연구에서는 현미 품종별 발아 전후의 일반성분 분석과 ${\alpha}$-amylase 활성분석, GABA 및 식이섬유 함량분석, 항산화 성분, 라디칼 소거 활성을 분석하여 기능적 가치를 평가하고자 하였다. GABA 함량은 일반현미는 0.07~28.24 mg/100 g의 함량을 나타내었으며, 발아현미는 11.13~49.72 mg/100 g의 함량을 나타내어 대체적으로 발아현미에서 높은 함량을 보였다. 특히 큰눈(KN)과 수원595호(S595)의 발아현미가 일반현미에 비해 크게 증가하는 것을 확인할 수 있었다. 또한 ${\alpha}$-amylase 활성은 발아현미에서 일반현미에 비해 1.77~70.25배 더 높게 나타났다. 총 폴리페놀 함량은 일반현미와 발아현미에서 각각 10.52~36.38 및 11.38~26.33 mg/100 g으로 나타났고, 플라보노이드 함량은 각각 3.55~13.39 및 3.52~9.78 mg/100 g으로 나타났다. 일반현미와 발아현미의 DPPH radical 소거 활성은 57.64~251.34 및 50.49~213.35 mg TE/100 g의 범위로 나타났고, ABTS radical 소거 활성도 일반현미에서 더 높은 활성을 보였다. 이상의 항산화 성분 분석 결과에서 발아 후 함량이 감소하는 것은 발아과정에서 살수에 의해 수용성 항산화 성분이 씻겨 내려가 감소하는 것으로 생각된다. 이와 같이 본 연구에서는 다양한 품종의 현미와 발아현미에 대한 일반성분과 항산화 성분 및 항산화 활성검정을 하였으며, 이는 현미와 발아현미를 이용한 가공품 제조에 기초자료로 활용될 것으로 기대된다.

Solid인 그루밀, 우리밀, 탑동밀, 진품밀 및 hollow인 진품밀 solid A, 진품밀 solid B, 고분밀, 은파밀의 밀 8품종의 줄기 특성과 총체수량에 미치는 영향을 조사한 결과 수수, 간장 및 줄기 직경을 고려한 줄기의 체적당 건물중에서는 solid type의 건물중이 무거웠으나 간장 및 줄기의 직경은 solid형이 작아서 stem당 무게에는 차이가 나타나지 않거나 오히려 가벼웠으며, 수수는 더 많아 단위 면적당의 건물중에는 차이가 없었다. 2. 직경이 비슷할 경우, 줄기와 잎을 포함한 tiller당 건물중은 solid인 4품종 평균이 더 무거웠고 hollow인 진품밀 및 진품밀의 solid형 near-iso-genic line 들의 건물중도 유의성은 없으나 solid형이 더 무거웠다. 3. 진품밀 및 Jin sol A 및 Jin sol B의 잎과 이삭을 제외한 줄기의 건물중은 5월 11일에는 차이가 없으나 5월 31일에는 solid형이 더 무거워 solid에 의한 건물중 증대효과는 생육 말기에 이르러 나타났다. This study was conducted to conform the effects of solid stemmed characteristics on total dry weight production in wheat as a haylage crop. There was no difference in total dry weight and total stem only dry weight between the two stem types, although the dry weights per unit cubic was heavier in solid type than hollow type. It seemed that shorter plant height and thicker stem diameter diminished dry weight increase of solid type. Stem dry weights with similar diameter on solid type was also heavier than hollow stem. The content of crude lipid of solid stem was higher than hollow, but crude fiber was lower. There was no significant difference between the two types on CP, ADF and NDF contents and RFV also. The dry weights of 30 stems of Jinpummil and it`s near-iso-genic lines at two time point, May 11th and 31st indicate that later haylage harvest is to be profitable for solid type.
