옥수수차의 기능성을 높일 수 있는 식품가공기술을 개발함으로써 새로운 소비 수요를 창출하고자 국내에서 육성된 옥수수 품종을 파종시기를 달리하여 수확된 옥수수로 볶음차를 제조하여 항산화 성분 및 활성 변화를 살펴보았다. 파종시기 및 품종별 원료곡의 일반성분은 전체적으로 유의적인 차이를 보였으며, 볶음 옥수수차 침출액의 품질특성 또한 전체적으로 파종시기에 따라 유의적인 차이를 보였다. 볶음 옥수수차의 총 폴리페놀 및 플라보노이드 함량은 볶음처리전후 유의적인 차이를 보였다. 4월 5일 파종한 평강옥은 볶음처리 전후에 총 폴리페놀 함량이 각각 $3.42{\pm}0.16$ 및 $12.22{\pm}0.67mg$ GAE/g으로 약 3.6배 증가하였다. 전체적으로 볶음 옥수수차의 총 폴리페놀 함량은 4월 5일 파종한 옥수수를 이용하여 제조한 옥수수차에서 높았다. 볶음 옥수수차의 DPPH 및 ABTS 라디칼 소거 활성은 볶음처리 전후 유의적으로 증가하는 것으로 나타났다. 4월 5일 파종한 강다옥의 DPPH 라디칼 소거 활성은 볶음처리 전후에 각각 $7.61{\pm}1.93$ 및 $240.37{\pm}8.82mg$ TE/g으로 약 31.6배 유의적으로 증가하였다. 4월 5일 파종한 평강옥의 ABTS 라디칼 소거 활성은 볶음처리 전후에 각각 $153.84{\pm}1.32$ 및 $843.54{\pm}3.64mg$ TE/g으로 약 5.5배 유의적으로 증가하였다. 원료의 일반성분과 볶음 옥수수차의 품질특성, 항산화 성분 및 활성 간의 상관성은 전체적으로 유의성을 보였다.

한국홍삼과 중국홍삼의 향 유형 및 강도를 관능적으로 비교한 결과 한국홍삼은 단 냄새와 구수한 냄새가 강한 반면에 중국홍삼은 흙 냄새, 나무냄새 및 건초냄새가 강한 경향이었다. 한국홍삼의 구수한 냄새와 단 냄새는 헤드스페이스추출물의 에테르분획, 그 중에서도 중성부에서 강하게 감지되었다.

The effective extraction of antioxidative substances from soybeans was studied by the mixed solvents of methanol or ethanol with water at 30$^{\circ}C$ and 85$^{\circ}C$. At accelerated peroxidation condition, POV (peroxide value) of soybean oil and TBARS (thiobarbituric acid reactive substances) value of egg yolk liposome with extracts added, were applied for the evaluation of antioxidative activity of the extracts. In the peroxidation of soybean oil, antioxidative substance of soybeans was extracted more effectively by methanol and at higher temperature 85$^{\circ}C$, and the deffated and roasted soybean extract (DRS) showed higher antioxidative activity. But in the Peroxidation of egg yolk liposome, methanol extract from the roasted soybeans (ROS) showed higher activity.

The purpose of this study was to select a cake ingredient acting as an emulsifier to retard the retrogradation of rice cake commercially available. For the purpose, Backsulgi, a traditional Korean rice cake, was prepared by adding various ingredients having high contents of lecithin such as raw soybean powder, parched soybean powder, soybean oil, egg yolk powder, and then the changes in the sensory and textural characteristics of the cakes were determined while storing them at the temperatures of 4$\^{C}$ and 20$\^{C}$ for 0, 1, 2 and 3 days. Based on the sensory evaluation, Backsulgi samples added with raw soybean flour were significantly different in roasted nutty smell, roasted nutty taste, softness, moistness, cohesiveness and overall quality compared with the control in the longer storage time at 20$\^{C}$.

Most of leaf teas, except flower tea, were considered as good materials with basic conditions for tea manufacture because water content was below 6 %, Crude protein was the greatest component in roasted young leaf tea, crude fats in roasted mature leaf tea and ashes in fermented young leaf tea. Caffein were present as the highest amount(5.18%) in steamed mature leaf tea, showing less amount than greenp teas. Catechin were contained as the highest amount in all kinds of teas, especially fermented young leaf tea. was the highest(9.57%). Tannin, which highly related with tea quality including astringent taste, color and perfume, were present as the highest amount in fermented young leaf tea.(중략)

This work was designed to determine the effect of steaming-Pretreatment on Physicochemical and functional properties of roasted Polygonatum odoratum roots. Steaming treatments led to some reduction in the contents of water solubles, such as total solid, reducing sugar and free-amino nitrogen of the unroasted samples. Moreover, roasting processing caused decrease in reducing sugar and free-amino acid, with increase in total soluble solid and browning color of the samples, which showed the dependence of steaming treatment as well as roasting temperature. Electron-donating ability and nitrite-scavenging ratio of the samples were also highly developed along with roasting processing at 17$0^{\circ}C$ within 35min. Considering the physicochemical and some functional parameters of water extracts of roasted samples, roasting at above 14$0^{\circ}C$ for over 55min or at 17$0^{\circ}C$ for around 35min was recommendable for the higher quality of Polygonatum odoritum tea, which conditions were similarly adapted for both steamed and unsteamed samples.

The result of the analytical experimental by HPLC on amino acid which is contained in such samples as white-raw-sesame, white-roast -seasame, black -raw -sesame, black-roast-sesame, raw-perilla seed and roast-perilla seed is as follows ; In the six smaples, the amino acid contents in raw seeds were all higher than those in roasted seeds, and the contents of alutamic acid and lysine were more reduced in roasted seeds than in raw seeds. All the amino acid contents except threoninewere highest in raw perilla seed. The amino acids which the six samples contain to a higher degree were in order of glutamic acid (18 %-21%), threonine(16%-19%), glycine (8%-9%), leucine(77.5%), aspartic acid (7%-7.4%), while methinine (1-2%) was contained least in all six samples followed by Isoleucine(3%).

The effect of partial replacement of flour with roasted soybean powder (0, 5, 10, 15, 20%) was examined by sensory and instrumental analyses of the bread. There were no significant changes in specific loaf volume up to 10% of replacement. Although the hardness of the bread increased with increasing storage time at higher replacement, there were no differences in springiness and cohesiveness compared with control. The yellow color of the soybean powder was reflected in the bread, however, it did not affect the preference. Overall, the bread with 10-15% soybean powder suggested to be acceptable.

This study was carried out in order to utilize ginseng marc (GM), a byproduct produced during the preparation of ginseng extract. For the utilization of GM as coffee-replacing beverage, GM was roasted at 140-23$0^{\circ}C$, for 10-30 min to generate coffee-like flavor and taste. The physicochemical changes in GM induced by roasting process was measured. Weight and moisture contents of GM abruptly decreased while roasting at various temperature and period of time, and the amount of water-extracted solid substances decorated beyond 23$0^{\circ}C$. Among the proximate components, total and free sugar decreased remarkably, while crude fat content increased. Crude protein content did not change by the roasting process. pH derides to pH 4.9 after 30 min at 20$0^{\circ}C$, but increased at higher temperatures. Hunter color L value of the GM powder decreased, whereas a and b values, increased up to 10 times as compared to that of the control. The brown color(O, D 490 nm) in 50% ethanol extract of the roasted GM was 46 times higher than that of the control.
