The aim of this study was to investigate the characteristics of paprika dried by various methods. Moisture content of dried paprika was higher in vacuum freeze-dried red paprika (DRP) (11.85%) than in vacuum freeze-drying of osmotic dried red paprika in sugar (RPS), vacuum freeze-drying of osmotic dried red paprika in fructose (RPF) and vacuum freeze-drying of osmotic dried red paprika in corn syrup (RPCS). Carbohydrate content of DRP was the lowest among the dried groups, but fat, protein, and ash contents were the highest in DRP. The pH of paprika was the highest in RPF (5.34), while it was the lowest in DRP (5.05). Reducing sugar and sugar contents of RPF were 28.59 g/100 g and $5.03^{\circ}Brix$, respectively, which are the highest level among the groups. All color values in inside of paprika were the highest in RPCS, while in outside of paprika, L value is the highest in RPCS, and the value of a, b were the highest in RPS. Regarding the texture characteristics of paprika, strongness, hardness, adhesiveness, chewiness and brittleness were the highest in RPS (p<0.05).

Microwave를 이용하여 밤 당침제품을 제조하고, microwave가 당침제품의 물성 및 조직구조에 미치는 영향에 대하여 조사하였다. 박피한 생율을 각각 일반가열방법으로 자숙한 후 당침을 행한 당침밤과, 일반가열방법으로 자숙하고 microwave로 당침한 밤, 자숙 및 당침 전과정에 microwave를 이용한 밤의 세 구로 제조하였다. 당침제품의 수분함량은 microwave를 이용하여 당침한 경우 가장 높게 나타났으며 조지방의 함량은 microwave를 이용하여 자숙 및 당침을 행한 당침제품에서 가장 낮았다. 총펙틴 및 HSP (hydrochloric acid soluble pectin)함량은 microwave로 처리한 제품에서 가장 낮게 나타났다. 당침밤제품의 물성 측정 결과 당침시에만 microwave처리를 행한 당침밤이 springiness를 제외한 fracturability, hardness, gumminess, chewiness에서 가장 낮은 값을 나타내었으며, microwave 처리를 행하여 자숙 및 당침을 행한 당침밤 간에는 유의차가 인정되지 않았다. 처리방법에 따른 당침밤의 조직을 주사전자현미경으로 관찰했을 때 당침을 행한 밤의 세포벽이 당침투에 따라 점성을 띠는 것을 볼 수 있으며 microwave 처리가 행해진 경우 세포벽이 심하게 파괴되었음을 관찰할 수 있었다.

In order to determine the optimal condition for making Yugwa (one of the Korean traditional cake) the textures in various conditions were studied by sensory test and texturometer. The changes of texture and fat content in the cake were measured along the period of storage. The results were as follows: (1) The cake were classified in 3 groups according to the leavening agent used in the procedure, namely refined rice wine (W), distilled liquor (L) and yeast group (Y). It was the refined rice wine group that had been 'the best' by sensory test. Its brittleness $(1.40{\pm}0.27)$ was higher than those of L and Y. (2) Crispness measured by bend test prior to soaking into syrup were 1.19, 1.23 and 1.63 in W, L, Y, respectively. (3) Chemical composition (%dry basis)) of Yugwa leavened with W included 9.3 of moisture, 1.3 crude protein, 6.7 crude lipid, 66.4 carbohydrate and 16.3 crude ash. (4) Brittleness decreased gradually along the period of storage while the rancidity increased. From the 40th days of storage, the change of brittleness and rancidity were marked as well as the scores of sensory test decreased significantly. (5) Content of linoleic acid in Yugwa decreased along the period of storage from 52.5% of total fatty acid on the first day to 10.9% on the 50th days Main fatty acids in Yugwa were oleic acid, palmitic acid and stearic acid, all of which were also decreased in content along the period of storage. One remarkable change was the appearance of an unknown fatty acid with 19.54 of retention time, in 50% of total fatty acid, on the 50th day of storage.

This study was investigated to obtain basic data which can be applied to processing of canned seasoned sea mussel. Shell was washed and steamed for 10 min before shucking. Sea mussel meat was seasoned with mixed seasoning sauce(soy sauce 23%, monosodiun glutamate 2%, sorbitol 2%, sesame oil 1%, vinegar 2%, starch syrup 15%, water 55%) for 30 min The seasoned sea mussel 60 g was vacuum packed in RR-90 can and fill with seasoning sauce 30 mL and grape seed oil 30 mL respectively, and then there was sterilized for various Fo values(Fo 8~12 min) in a steam system retort at $121^{\circ}C$. pH, VBN, amino-N, total amino acid, free amino acid, color value, texture profile, TBA value, mineral content, sensory evaluation and viable cells count of the canned seasoned sea mussels sterilized with various conditions(Fo 8~12 min) were measured. The same experimental items were also measured during storage. There was no remarkable difference between sterilized conditions and sensual characteristics. The results showed that the product of filled with grape seed oil sterilized at Fo 8 min was the most desirable.

Korean ginseng (Panax ginseng C.A. Meyer) preserved in syrup, known as ginseng Jung Kwa (GJK), is a popular traditional snack in Korea. We investigated the effects of heat processing time on total phenolic content and antioxidant capacity of GJK. Water extract was prepared from GJK with different heat processing times, 3 hours (GJK-3), 6 hours (GJK-6), or 12 hours (GJK-12), with sonication for 2 hours. The GJK extract contained total phenolic content in the following order: GJK-12 (2.28%)>GJK-6 (1.57%)>GJK-3 (1.29%). Both the peroxy and hydroxyl radical-scavenging activity and cellular antioxidant capacity of GJK extract was significantly enhanced with increasing heat processing time. The hydroxyl radical-scavenging activity of GJK-12 extract was greater than that of the GJK-3 and GJK-6 extracts, consistent with metal chelating capacity and reducing capacity. In a cellular model, the GJK extract effectively reduced 2,2'-azobis(2-amidinopropane) dihydrochloride, $Cu^{2+}$-, and $H_2O_2$-induced oxidative stress, with GJK-12 and GJK-6 extracts demonstrating greater cellular antioxidant capacity than the GJK-3 extract. These results suggest that heat processing time can contribute to the antioxidant capacity of GJK and that GJK extract may have the potential to be used as an effective dietary antioxidant to prevent oxidative stress-related diseases.

본 연구는 고성능 준구조용 양면 점착테이프 제조를 위해 2-ethylhexyl acrylate(2-EHA)와 acrylic acid(AAC)를 사용하였고, UV 조사에 의해 시럽을 준비하였다. 양면 점착테이프의 두께, 무기물 충전제 함량 및 충전제 종류에 따른 준구조용 물성에 미치는 영향을 고찰하였다. 테이프의 두께 및 젖음시간이 증가할수록 박리강도가 증가하였다. 두께가 얇은 점착테이프($250{\mu}m$이하)의 경우 무기물 충전제의 true density가 낮을수록 적용시간 경과에 따라 박리강도가 높게 나타났다. 무기물 충전제 입자가 클수록 초기 박리강도가 높게 나타났으며, SEM 이미지를 통해 점착테이프 내에 무기물 충전제의 크기를 확인하였다. 다양한 무기물 충전제 및 함량에 따라 박리강도 증가와 함께 전단접착강도가 증가하는 비례관계를 보였으며, $0.1{\mu}m$인 양면 점착테이프에서 무기물 충전제는 전단접착강도에 더 영향을 주었다. 이러한 결과로부터 박막형 아크릴 양면 점착테이프는 준구조용 물성을 필요로 하는 용도에 사용가능할 것으로 사료된다.

This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.
