  • The main objective of this study was to characterize physico-chemical properties, sensory property and oxidative stability of safflower seed obtained by various roasting temperature and time. The contents of water soluble solids decreased in the higher roasting temperature and time. Sensory evaluation of safflower seed roasted in various conditions showed significant differences in taste, color, flavor and palatability. The safflower seed roasted at $190^{\circ}C$ for 20min had the best palatability. At the change of Hunter's values, L values were decreased, and a, b and ${\Delta}E$ values were increased in the higher roasting temperature and time. The content of free sugars such as sucrose and raffinose were reduced significantly in higher roasting time of $190^{\circ}C$ and $210^{\circ}C$. During the storage period after roasting treatment, peroxide values (POV) were highly increased after eight months at the all treatment except for $150^{\circ}C$. Therefore, it is inadequate over eight months after roasting treatment.

  • Fermented milk was prepared from skim milk supplemented with Salicornia herbacea extract powder (SHEP) at the levels of 0∼0.4% (wi v) and was fermented with Lactobacillus acidophilus, Streptococcus thermophillus and Bifidobacterium longum. Quality characteristics of prepared fermented milk were evaluated for acid production, visible cell numbers, viscosity and sensory property during fermentation at 37$^{\circ}C$ for 6 hr. Supplementation of 0.1% SHEP stimulated the growth of lactic acid bacteria which showed the highest number of viable cell counts (9.23 log CFU/ml), and also enhanced the acid production which was pH 4.23 and titratable acidity 0.64%, and increased the viscosity (1,365 cps) after 6 hr incubation. The sensory scores of fermented milk supplemented with 0.1% SHEP were higher than other supplemented contents in taste, texture, flavor, aftertaste and overall acceptability. When the storage abilities of fermented milk supplemented SHEP at 6$^{\circ}C$ for 12 days were evaluated, its quality-keeping properties were relatively good in the fermented milk supplemented with 0.1% SHEP.

  • Two types of onions cultivated with different methods of sulfur application (designated as S-1 and S-2) were examined for their physicochemical and sensory properties, and then compared with onions without sulfur application as a control. During cultivation, dietary sulfur methylsulfonylmethane (MSM) was sprayed on the leaves twice starting at 2 months before harvest, with one month intervals for S-1. For S-2, the MSM was applied once onto surface soils before sowing, and then once again on the leaves at 2 months before harvest. Thiosulfinate, a major sulfur-containing compound in onions, increased in the order of control, S-1, and S-2, without noticeable differences in the strength of spicy hot taste and flavor. The S-2 onions demonstrated a total reducing capacity three times higher than control and S-1 did. It indicates that the application of sulfur would positively affect the quality of onions under the condition where sufficient time is given for soil mineralization.

  • This study aimed to find optimum addition of jujube powder to glutinous rice in the preparation of daechu injeolmi (rice cake). The daechu injeolmi added with 10% jujube powder gave the highest moisture content of 52.9% among treatments. Higher amount of jujube powder up to 14% resulted in lower 'L' and higher 'a' values of the cake. Hardness of the cake showed the lowest value for the 10% jujbe-added cake during the storage of 24 hours, while it was so for 14% jujube-added cake after 36 hour storage. Little change was observed with time in the cohesiveness for the cake added with jujube powder in more than in the 8% level. 10% addition of the jujube powder was found to be the best recipe based on the sensory qualities of softness, chewiness, moistness and overall acceptability, which were also well correlated with physical properties.

  • Every year in the ocean, various accidents occur frequently and illegal fishing is rampant. Moreover, their size and frequency are also increasing. In order to reduce losses of life or property caused by these, it is necessary to have a means to perform remote monitoring quickly. As an effective platform of such monitoring means, an Unmanned Aerial Vehicle (UAV) is receiving the spotlight. In these situations where marine accidents or illegal fishing occur, main targets of monitoring are ships. In this study, we propose a UAV based ship monitoring system and suggest a method of determining ship positions using UAV multi-sensory data. In the proposed method, firstly, the position and attitude of individual images are determined by using the pre-performed system calibration results and GPS/INS data obtained at the time when images were acquired. In addition, after the ship being detected automatically or semi-automatically from the individual images, the absolute coordinates of the detected ships are determined. The proposed method was applied to actual data measured at 200 m, 350 m, and 500 m altitude, the ship position can be determined with accuracy of 4.068 m, 8.916 m, and 13.734 m, respectively. According to the minimum standard of a hydrographical survey, the ship positioning results of 200 m and 350 m data satisfy grade S and the results of 500 m data do grade 1a, where the accuracy is required for positioning the coastline and topography less significant to navigation order. Therefore, it is expected that the proposed method can be effectively used for various purposes of marine monitoring or surveying.

  • Quality characteristics of tofu as affected by addition time (before or after coagulant) and the amount (0, 3, 6, and 9%) of astringent persimmon fruit (Diospyros kaki T. cv. Cheongdobansi) powder added were investigated. Yield and sensory acceptability were higher in tofu prepared by adding persimmon before than after adding the coagulant. The yield of tofu with added persimmon was higher than that of the control. The L value of the tofu decreased as the amount of added persimmon increased. Hardness, chewiness, and crispness of tofu made with 6% persimmon were higher than those of the others. DPPH radical scavenging activity tended to increase as persimmon concentration increased but no significant difference was observed between the 3% and 6% added persimmon treatments. A sensory evaluation showed no significant differences in aroma, beany, astringency, and texture. However, the 9% sample had the significantly lowest score for overall acceptability. Thus, astringent persimmon powder (3-6%, before coagulant addition) can be utilized as an additive during tofu processing.

  • To prolong the shelf-life of chicken breast meat, samples were treated with gel packs containing slow-released chlorine dioxide ($ClO_2$) gas at 7~15 ppm for eight days at $4^{\circ}C$. The microbial, physicochemical properties and sensory evaluation of the treated samples were investigated. The total number of bacteria in the control increased during storage and showed 6.78 log CFU/g on the 8th day of storage, but $ClO_2$ gas treatments showed 6.24~6.58 log CFU/g at the same time. The initial pH of chicken breast meat was 6.00 and gradually increased during storage. And $ClO_2$ gas treatments did not show any significant difference from the control during storage period, but maintained a generally lower pH than that of the control. The lightness, redness, and yellowness during storage were not significantly different between the control and the 7~10 ppm $ClO_2$ gas treatments. However, as the storage period was increased, the redness of 15 ppm $ClO_2$ gas treatment was reduced. The cooking loss and shear force were not different between the control and $ClO_2$ gas treatments during the storage period. Volatile basic nitrogen (VBN) increased in the control from the 6th day of storage and 23.80 mg% in the 8th day of storage. However, VBN of $ClO_2$ treatments showed lower than that of the control. In the change of sensory evaluation during storage, 10 ppm $ClO_2$ treatment showed the highest preference in odor, appearance and overall acceptance during storage period.

  • This study examined the quality characteristics of pork patty samples by the addition of hot air-dried Kimchi powder at levels of 0, 1, 2, and 3%(w/w) to the formulation. The CIE $L^{\ast}$-values of the raw patties decreased with increasing Kimchi powder content(p<0.05), whereas the CIE $a^{\ast}$-values and $b^{\ast}$-values of samples increased with increasing Kimchi powder content(p<0.05); however, after cooking, there were no significant differences in $L^{\ast}$-values among the treatments (p>0.05). Due to the acidity of the Kimchi powder, the treatment groups showed reductions in pH; but after cooking, pH had increased(p<0.05). The patties containing Kimchi powder also had decrease cooking losses and reduction of patty diameter(p<0.05). Finally, the results of sensory and texture property analyses indicated that higher overall acceptability and springiness, lower hardness, were attained by the addition of Kimchi powder.
