  • This study was to investigate the physiological activity of cookies with Sanguisorba officinalis L. powder. Our results showed that the pH of the cookies ranged from 6.34 to 6.29, and the density ranged from 4.12 to 4.40. Increasing the amount of Sanguisorba officinalis L. powder in the cookies decreased the spread factor of the cookies and tended to decrease lightness (L) in the Hunter color value with yellowness (b) and redness (a) increased. For the textural characteristics, the addition of Sanguisorba officinalis L. powder increased hardness. The sensory evaluation showed that the cookies with Sanguisorba officinalis L. powder were preferred more than those without in color, odor, texture, taste and overall preference. Based on the results above, the cookies that contained 3% of Sanguisorba officinalis L. powder presented the best quality.

  • The quality characteristics of bread processed with the addition of roasted safflower seed powder were evaluated Safflower seed powder was roasted at 180$^{\circ}C$ for 20 min and pulverized below 45mesh size. Bread was processed by addition of control, 1, 2, 3 and 4% safflower seed powder at basic formulation. Dough raising power was increased as the addition of safflower seed powder increase, but Hunter's L value was decreased, From the sensory evaluation of safflower seed bread, color score was decreased significantly as the addition of roaste safflower seed powder increase, but overall acceptance had no significantly difference between control and added 4% of safflower seed.

  • Physicochemival properties of ginseng roasted at 170 to $250^{\circ}C$ were investigated. Soluble solid contents in roast ginseng increased until $200^{\circ}C$, but decreased at higher temperature than $200^{\circ}C$. Contents of reducing sugar and protein were decreased and pH values were dropped, while optical density, acidic polysaccharide contents, precursor of brown pigments and hydrogen donating activities by DPPH were increased according to increasing in roast temperatures. The color distribution of roast ginseng expressed as Hunter L, a and b values demonstrated that lower L values and higher a values were observed according to higher temperature, but b values were almost not changed.

  • In order to improve qualities of kochujang, various fruit juices such as apple, orange, pineapple and grape were added to the raw material of kochujang instead of the part of water. It was apparent in the kochujang with pineapple juice that organic acids originated from fruit juices increased titrable acidity and decreased pH. Free sugars and organic acids in the kochujang that was fermented during three months were degraded or might be used by microorganism after ten months of fermentation. Kochujang with grape juice showed relatively dark color, which had a good agreement with the changes of Hunter a-value. Sensory evaluation test about tastes, flavor and color showed that the kochujang with pineapple juice was preferred to others.

  • To evaluate a pigment of the flower of cockscomb, Cclosia critata. as a natural food colorant, jelly-po, candy and sherbet were chosen as model foods and colorized to red with the pigment of the flower. Color changes were evaluated by analyses with Hunter color difference colorimeter. Lovibond tintometer and UV-visible spectrophotometer. Also sensory evaluation was carried out. The results obtained indicated that the red pigment of the flower had a good potential as food colorant, when it is utilized under the certain limited conditions: low water activity such as candy or low temperature. Data obtained indicated good correlation between instrumental analyses and sensory evaluation as well.

  • The dried cinnamon was extracted with water and 70% ethanol and studied for the several extraction conditions of temperature, time, solvent addition ratio and number of extraction on mineral components and physical properties of the extracts. Mineral components significantly increased as the extraction temperature increased. More than 8 hours of extraction showed a little improving while solvent ratio (V/W) up to 60 times (V/W) significantly increased the mineral components, particularly Cu, Zn, Fe, Na in water extracts and Fe, Mn, K in 70% ethanol extracts. Absorbance at 285 mm decreased as the temperature raised up to the range of $60{\sim}80^{\circ}C$. The Hunter a-value was much affected with extraction conditions and L-value and transmittance were changed similarily while pH was little changed.

  • This study developed patties using the Antarctic krill Euphausia superba and investigated the food quality of the patties. Three different types of krill patty were produced: krill patties with added 1) corn oil (CKP), 2) AA grade surimi (AKP), and FA grade surimi (FKP). Their proximate composition, Hunter color value, texture, sensory evaluation, and levels of astaxanthin, cholesterol, calories, total amino acids, fatty acids, and fluoride were investigated. The moisture and crude protein contents were highest in FKP. The calorie and astaxanthin contents were highest in CKP and lowest in AKP. The cholesterol content was highest in CKP and lowest in AKP. Measuring the Hunter color value of cross-sections of the patties, the L values were highest for FKP, and the a and b values highest for AKP. The total amino acids were highest in FKP and lowest in CKP. The major fatty acids were highest in FKP. The hardness and chewiness were highest in FKP and lowest in CKP. The fluoride content was highest in AKP and lowest in FKP. The sensory evaluation had the highest scores for FKP and lowest for CKP. Accordingly, FKP appears to have better food quality than the other two products.

  • Sea lettuce(Monostrima nitidum) were treated with several alkali agents on condition with water blanching at 9$0^{\circ}C$ for 10 min., and followed by drying and powdering, thus, the power samples treated and the not treated were then allowed to be stored at $25^{\circ}C$, dark place for 5 months. The sea lettuce powder samples were evaluated for green color intensity and volatile flavor at a month intervals. The green intensity of the samples were measured by using Hunter-lab colorimeter, therefore, the decoloration of greenness were seen in both of the samples treated and the not treated, but there were slight inhibitory effects on decoloration in the treated with alkali agents, especially in the treated with KHCO$_3$.The volatile flavor of the samples were collected by simultaneous distillation-extraction, and then the 31 flavor compounds were separated on HP-5 capillary column(25m$\times$0.25mm i.d) and identified by using GC-MS. From these results, it was presumed that the characteristic impact flavor compounds were $\beta$-cyclocitral, $\beta$-cyclohomocitral, ionene, $\alpha$-ionone and $\beta$-ionone. The total content of the characteristic impact flavor compounds decreased in the samples treated with alkali agents more alkali agents more than in the not treated, but lee decrease was observed in the treated with KHCO$_3$.

  • This study was carried out to find out the color, rooking quality and storability of the oil-added milled rice. Soybean oil was added at the level of $0.07{\sim}0.15%$ in the last cycle of milling process. Fat content of the oil unadded milled rice was 0.65% and that of the oil-added one were 0.70% to 0.73%. Water uptake ratio, expanded volume, total soluble solids and iodine blue value of milled rice during cooking were lower in the oil-unadded one. The oil-addition to milled rice lowered the value of Hunter L, a, b and whiteness. Changes in fat acidity of the oil-added milled rice was similar to that of the untreated rice.

  • Alkaline treatment during preparation of anchovy extracts was studied for its changes in some of the physicochemical and sensory qualities. The dried anchovy was blended in 0-0.5N NaOH solutions and then incubated at $60^{\circ}C$ for 6 hours. After extraction the suspensions were neutralized and centrifuged. The results showed that the yields of solids and protein were increased by 3-5 fold of those of water extract as alkaline concentration and treatment time increased. The intrinsic viscosity showed little changes for the extracts prepared with 0-0.2N NaOH solution while the extracts prepared with over 0.3N NaOH resulted a initial small decrease followed by a rapid increase to the maximum point. The changes in color expressed as Hunter 'L', 'a' and 'b' values showed that the L value increased rapidly until 3 hours of treatment followed by a decrease, and 'a' and 'b' values were increased a little. The intensities of odor and taste were markedly increased by 2-3 fold for all of the descriptions investigated where clam-like odor and taste and sea complex odor were particularly significant.
